Producers
(ex: grass)
If a pesticide is released into the environment that kills most of the grasshoppers, which of the following is most likely to occur?
OA.
an increase in population for all organisms
ОВ.
a decrease in the number of snakes
C
an increase in the number of hawks
D
a decrease in the amount of grass
Answer:
It should be A. If the pesticide is released, then they die, and the consumers of the grasshopper (snake) dies due to no grasshoppers, then the animal that consumes the other animal (hawk eats snake) that eats the grasshopper will die because there aren't enough of that animal for it to eat. the only thing that lives is the grass.
Sorry if I'm wrong, but i hope it helps.

Homeostasis Review - List some things in living things that need to be regulated
Answer:
Homeostasis The tendency to resist change in order to maintain a stable, relatively constant internal environment
Explanation:
The body maintains homeostasis for many factors. Some of these include body temperature, blood glucose, and various pH levels.
Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.
Feedback loops
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values. An example of a negative feedback loop is body temperature regulation.
Example of negative feedback loop
Example of negative feedback loop
The maintaining of body temperature is an example of a negative feedback loop. When body temperature increases, there are mechanisms that work to decrease temperature, and vice versa.
In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
Example of positive feedback loop
Negative feedback loop=
Feedback loop that acts to oppose the triggering stimulus
Positive feedback loop= Feedback loop that amplifies the starting signal

Answer:
desert plants that need to conserve water like a cactus.
Explanation:
Thick fleshy stems with thick waxy covering would most likely be useful adaptations for desert plants to conserve water.
What are desert plants?Desert flora that require water conservation Prairie plants that must withstand flames desert flora that require water, conservation thick waxy covering would most likely be a useful adaptation.
The challenge for plants that thrive in highly dry environments is finding and retaining water.
Xerophytes are plants that can survive in extremely arid conditions. Their adaptations may aid them in consuming more water, reducing water waste, or storing water for later use.
Therefore, water is so scarce in deserts, plants there need to minimize water waste. They have thin foliage that enable them to retain more water during the summer.

Hypertonic solution?
H2O
LH₂O
Answer:
[tex]\boxed {\tt B. \ Isotonic}[/tex]
Explanation:
We can see that the H₂O or water is leaving the cell and entering the cell at the same rate.
An isotonic solution has the same amount of solute outside the cell and solution inside cell. Therefore, when the water moves across the membrane, the water inside the red blood cell does not change.
Therefore, the best answer choice is B. Isotonic

Which statement best explains why BaCl2 is an ionic compound?
O A. BaCl, has a net charge of -2.
O B. The neutral atom Ba gains 2 electrons.
O C. BaCl, has a net charge of +2.
OD. The neutral atom Cl gains 1 electron.
Answer:
D. The neutral atom Cl gains 1 electron.
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Barium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.89. There is large difference is present. That's why two valence electron from barium is transfer to the chlorine. Barium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations. There are two valence electron lost by barium while chlorine required one electron to complete the octet thus two chlorine atoms are bonded with one barium atom. Each atom of chlorine carry -1 charge while one barium atom have +2 charge.

Discus immune response to a pathogen through the oral (oral-anus) and respiratory route
Answer:
The complete explanation of the immune response to a pathogen through the oral (oral-anus) and respiratory route is given below in explanation part .
Explanation:
In order to provide host protection against pathogens wherever they can enter or spread, the immune system can be seen as an organ distributed throughout the body. A collection of anatomically distinct compartments can be distinguished within the immune system, each of which is specifically adapted to produce a response to pathogens present in a specific set of body tissues. The basic concepts underlying the initiation in the compartment of the peripheral lymph nodes and spleen of an adaptive immune response. This is the compartment that responds to antigens that have dispersed through the blood or penetrated the tissues. The mucosal immune system (commonly represented by the MALT) is a second compartment of the adaptive immune system of equal size to this, and situated near the surfaces where most pathogens enter. Body cavities (peritoneum and pleura) and skin are two other distinct compartments. These compartments are characterized by two main characteristics. The first is that immune responses induced within one compartment are generally restricted to that specific compartment in terms of speech. The second is that by expressing homing receptors that are bound by ligands, known as addressins, which are specifically expressed within the tissues of the compartment, lymphocytes are limited to particular compartments. The body's mucosal surfaces are particularly susceptible to infection. Because of their physiological roles in gas exchange (the lungs), food absorption (the gut), sensory roles (eyes , nose , mouth, and throat), and reproduction (uterus and vagina), they are thin and permeable barriers to the interior of the body. Obvious susceptibility to infection is provided by the need for permeability of the surface lining of these sites and it is not surprising that the vast majority of infectious agents via these routes enter the human body.
When contemplating the immunobiology of mucosal surfaces, a second essential aspect to bear in mind is that the gut serves as a conduit of entry in the form of food to a large array of foreign antigens. The immune system has developed mechanisms to prevent, on the one hand, a robust immune response to food antigens and, on the other, to detect and destroy the entry of pathogenic organisms via the gut. The majority of the gut is heavily colonized by commensal microorganisms, which live in symbiosis with their host, to further complicate matters. In certain ways, these bacteria are beneficial to their hosts. They provide protection by occupying the ecological niches for bacteria in the gut against pathogenic bacteria. By synthesizing vitamin K and some of the components of the vitamin B complex, they also serve a nutritional role in their host.
Peyer's patches of the small intestine, the appendix, and solitary lymphoid follicles of the large intestine and rectum are the other major sites inside the gut mucosal immune system for the activation of immune responses. The patches of Peyer are an extremely important location in the small intestine for the activation of immune responses and have a distinctive shape, forming domelike structures that reach into the intestinal lumen. Specialized epithelial cells reside in the overlying layer of follicle-associated epithelium of the Peyer's patches. Instead of the microvilli present on the absorptive epithelial cells of the intestine, they have microfolds on their luminal surface and are known as microfold cells or M cells. By endocytosis or phagocytosis, M cells pick up molecules and particles from the gut lumen. This material is then transported to the basal cell membrane, where it is released into the extracellular space, via the interior of the cell in vesicles. This mechanism is referred to as transcytosis. The cell membrane of M cells is extensively folded at their basal surface around underlying lymphocytes and antigen-presenting cells that take up the transported material released from the M cells and process it for the presentation of antigen.
Explain the contribution of antigenic determinant in false negative and false positive tests
Answer:
Contribution of antigenic determinant in false negative -: Popular causes of false-positive ELISA include: flu vaccine administration, presence of HLA-DR antibodies in women with multigravity, presence of rheumatoid factor. Contribution of antigenic determinant in false positive tests -: Positive RPR exam, hypergammaglobulinemia and autoimmune hepatitis (e.g. multiple myeloma).Explanation:
Much attention has been paid to the specificity and sensitivity of this assay since regular ELISA screening of blood donors for anti-HIV antibodies was implemented. It was found that inadequate coating of the microtitre plates with HIV-antigen could lead to false negative results. It is important that the ELISA test kit manufacturers use control systems that guarantee adequate antigen coating.

1. John is suffering from autosomal dominant deafness (D) and his wife Mary is normal.
Considering complete penetrance for this trait (P=1), what is the probability that this
couple's first child would have this disorder?
Answer:
Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

EXPLAIN Make a claim about the affect urbanization has on
biodiversity. Does urbanization always decrease biodiversity? Use
evidence to support your claim and explain your reasoning. Address
the following questions in your answers
• What are the main factors that lead to biodiversity loss in urban
areas?
• How is the size of a habitat related to its biodiversity and its stability?
• Can an ecosystem in an urban area ever return to its previous state?
Answer:
Urbanization decreases biodiversity. Land development reduces the size of habitats and affects the availability of resources. Larger habitats have a greater potential for biodiversity. If some of the natural habitat is retained, the impact of urbanization may not be as destructive. Assuming human development and its resulting pollution aren’t too extensive, an abandoned urban area could return to its previous ecosystem.
Explanation:
It is found that urbanization affects the biodiversity and the relationship between them is not linear as with the increase in urbanization the area of forest keeps on decreasing which reduces the natural habitat of many species and lead to their extinction.
What affects biodiversity?
Biodiversity of an area is the total number of living organisms (species) living in a particular area. Most of the biodiversity are found in the forests as these are the natural habitats of many animal species.
The ecological studies conducted on the urbanization and biodiversity have found that the urbanization generally shows a negative impact on the biodiversity levels of an area. The relationship between biodiversity and urbanization is not always a linear relation. As the area of urban citied increases, the area of forest decreases which lead to extinction of many important species.
The forests are the natural habitat of animals, as the natural habitat decreases the biodiversity of an area also decreases which affects the stability of the forest.
An ecosystem in an urban area can be returned to a biodiversity-rich area by introducing species and making the habitat more favorable for them.

Describe how you might figure out if something was made out of cells.
Answer:All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.
Explanation:
To determine if something is made out of cells, several approaches can be employed, including microscopic and biochemical assays for physical and chemical assessments.
Visual inspection using a microscope can reveal the presence of cell-like structures, such as membranes, nuclei, or organelles. Staining techniques, such as fluorescent dyes or immunohistochemistry, can further enhance the visibility of cellular components.
DNA analysis can also be conducted by extracting genetic material from the sample and performing sequencing or polymerase chain reaction (PCR) to detect DNA specific to cells.
Biochemical assays can be used to identify cellular components, such as proteins or enzymes, which are characteristic of cell composition.

D. Each ecosystem has a preferred disturbance frequency, Disturbances that occur at the right frequency, not too frequent or infrequent, will promote diversity at the landscape scale. Disturbances that are too frequent or to infrequent will result in biodiversity decreases.
What is biodiversity?Biodiversity refers to the variety and abundance of different species that exist within an ecosystem or region. It includes the diversity of different species, as well as the diversity within species (such as genetic diversity) and the diversity of ecosystems.
Biodiversity is important because it helps to maintain the health and functioning of ecosystems, and it is also a source of economic, cultural, and recreational value. Biodiversity can be affected by a variety of factors, including habitat loss, pollution, climate change, and the introduction of non-native species.
Disturbances are a natural part of ecosystems, but that the frequency of disturbances can affect the diversity of species in the ecosystem. It also suggests that each ecosystem has its own "preferred" disturbance frequency, and that disturbances that occur at the right frequency can promote biodiversity, while disturbances that are too frequent or too infrequent can lead to decreases in biodiversity.
