Meiosis is a type of cell division that produces:
A. Zygotes
B. Chromosomes
C. DNA
D. Gametes
Answer:
B. Chromosomes
Explanation:
This process is required to produce egg and sperm cells.
Meiosis is a type of cell division that produces: Gametes.
Meiosis is called a form of reproduction of cells, specifically, it allows a diploid cell to divide twice consecutively, generating four haploid cells (with half the number of chromosomes each).
This type of cell division is key to sexual reproduction, since through meiosis organisms produce their gametes or reproductive cells.Haploid cells are the gametes or reproductive cells that are involved in sexual reproduction, that is, they are the sperm (male gametes) and the ovules (female gametes).When a sperm and an egg fuse with each other during fertilization, each of them contributes half of the genetic load of the new individual.Thus, both haploid sets of each gamete combine to form a complete diploid set, which is the genome of the newly formed individual.Therefore, we can conclude that meiosis is an essential process prior to sexual reproduction, since gametes are formed during this process.

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.

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.

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.

Food webs contain many different, linked food chains.
Food webs contain only producers, not consumers.
Food webs do not include decomposers.
Food webs exist in aquatic environments, food chains exist in terrestrial environments.
Answer:
You answer is a) Food webs contain many different, linked food chains.
Explanation:
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.And so on for all the other animals in the food chain.

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

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.

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.
