Answer:
D. Homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Hence, regulation of the internal body temperature of the bumblebee is an example of homeostasis.

5. The reactants and products for respiration are exactly the
same for a plant cell and an animal cell, the difference is
the _______
of the reactants.
Answer:
Source
Explanation:
Respiration, which occurs in all living organism, is the metabolic process by which organisms obtain energy (ATP) via the breakdown of their food substances.
The process of respiration in plant and animal cells is similar in the sense that reactants and products for respiration are exactly the same for both cells. The reaction is as follows:
C6H12O6 (glucose) + 6O2 = 6CO2 + 6H2O
The difference between this process in plant and animal cells is the SOURCE of the glucose or food molecule that is broken down. Plants get their food from PHOTOSYNTHESIS (autotroph) while animals get theirs by feeding on other organisms (heterotroph).

Which of the following explains why artificial selection is described as artificial?
It is the label used to show which animals have been given hormones and artificially-made nutrients.
ООО
It deals with synthetic or superficial genes and traits like color, markings, size, and speed.
It is the opposite of natural selection, in which organisms adapt to their environments without human intervention
O It alludes to the process of artificial insemination, a process of unnaturally planting a fertilized egg.
Answer: it deals with synthetic or superficial genes and traits like color, markings, size, and speed.
Explanation: a good example of artificial selection is breeding dogs. people mix breeds to get these kinds of quality’s.
Artificial selection is the opposite of natural selection, in which organisms adapt to their environments without human intervention. So, the correct option is C.
What is Artificial selection?Artificial selection, commonly known as selective breeding, is the intentional breeding of particular plants or animals by humans to advance certain desirable traits. On the other hand, natural selection occurs in the wild when organisms with favorable characteristics are more likely to survive and reproduce.
The term "artificial" in artificial selection refers to deliberate human manipulation of the reproductive process as opposed to allowing natural processes to occur. The use of nutrition, hormones or artificial insemination is not mentioned. A wide variety of traits, including color, markings, size, movement, and other physical or behavioral characteristics, are possible through artificial selection.
So, the correct option is C.

How to use informal assessment effectively to prepare for examination
Answer:
Kindly check explanation
Explanation:
The use of informal assessment while preparing for an examination could take various forms. Informal assessment include the use of actual grading of a set of questions which one decides to test his/her knowledge on in other to check or evaluate performance. Similarly, one may employ the use of a colleague or friend to set out a few likely questions from the subject or the use of previous test or examination questions to ascertain how well one has grasped or covered in the subject. Also, one could personally reminisce on the areas covered, frame likely questions in reasoning and check if the appropriate response could be proffered.
A few years ago, the labels from one class section's experimental treatments plants fell off in the greenhouse and got swept away! One group was the only group in the section to test the effects of indole acetic acid (IAA) on bean plants. The IAA group applied lanolin paste to one side of their bean stems. What should they look for in order to identify their experimental plants from other groups
Answer:
The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.
Explanation:
Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.

About the question:
I failed to find the complete question. However, I propose the following answer and explanation according to the given statement.
Answer:
Natural selection
Explanation:
Natural selection is the product of the interaction between phenotype and environment, which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases, adaptations -as a result of natural selection-, can be correlated to environmental factors or selective pressures applied by other organisms or habitats. These organisms might change or modify their habits according to the environmental pressures that are acting on them. Natural selection favors these new habits and behavior. The better an organism can behave in an environment, the higher chances to survive.
In the exposed example, if assuming that these two populations belong to the same species, they might behave differently from each other if they are, for instance, occupying different niches, changing their feeding habits, competing with other species, among other factors. If these two groups are separated in space and/or time, they might receive different environmental pressures that lead them to change the original behavior to a new one. And as both groups are separated, those pressures probably differ, modeling a behavior adapted to a specific niche.
Answer:
The correct answer is natural selection.

La Selva Biological Station and the Braulio Carrillo National Park in Costa Rica are an example of La Selva Biological Station and the Braulio Carrillo National Park in Costa Rica are an example of use of island biogeography theory in guiding conservation. poor planning in conservation efforts. use of corridor theory in guiding conservation. use of metapopulation dynamics in guiding conservation.
Answer:
use of corridor theory in guiding conservation
Explanation:
Conservation corridors, also known as green corridors, are small fragments of wildlife habitat that are installed to connect fragmented habitats. It is believed that green corridors can maintain healthy genetic diversity levels by connecting habitat patches that otherwise would be isolated (i.e., these corridors increase gene flow between isolated populations). Thus, green corridors are used to alleviate the harmful effects of habitat fragmentation on population viability. Species that make use of green corridors can be classified into passage users, which occupy corridors during brief periods of time, and corridor dwellers, which occupy corridors during long periods (even all life).

Suppose we have access to the four nucleotides which compose DNA: A, T, C and G. Placed into a sequence with one another, they form a code which can be read by the cell to provide a blueprint for the creation of proteins. When forming a sequence of three nucleotides, the sequences TAA, TAG, and TGA are codes to tell the cell to stop reading the DNA. Assume each sequence of nucleotides is equally likely to be formed.
A. How many possible ways are there to form a sequence of three nucleotides? - 64
B. Of the possible ways to form a sequence of three nucleotides, what is the probability to form a stop sequence? = 0.0469
C. What is the probability that a sequence that is not a stop sequence is formed? 64-3 = 61 61 = 0.983
D. For a three-nucleotide sequence, G is engineered to be in the third place. For the remaining two nucleotides in the sequence, C cannot be in the second place (for example CTG is allowed but not TCG). How many sequences can be formed?
E. Of the number of sequences found in Part D, what is the probability that a stop sequence is formed?
Answer:
The correct answer is :
A. we know there are four nucleotides and three sequence makes a triplet code then total possible ways are:
4^3 = 4×4×4= 64 ways.
B. The stop codons by 64 amino acid or triplet codes: TAA, TAG, and TGA then the probability would be = 3/64 = 0.0469
C. the probability that a sequence that is not a stop sequence is formed = total minus probability of stop codons:
64-3 = 61
61/64 = 0.953
D. G at end place and c should not be in the middle then:
the codes will be =
ATG

An old alternative hypothesis for the evolution of infanticide was that parents killed offspring (including their own) when food was short for the good of the group. On the basis of a modern view of adaptation, why is this not a good explanation for the evolution of infanticide
Answer:
On the basis of gender preference.
Explanation:
In the modern view of adaptation, the main cause of infanticide is not the food but the gender preference. In many societies, people killed their infant when they knew that the infant is a girl. They thought that having a girl is curse or shameful thing so they kill the infant. These type of people wants male baby or prefer male child so that's why they kill the infants. In the ancient times, infants were killed that were abnormal or having any defects but today it happen due to gender preference.

Explanation:
what are all the steps of the water cycle
Answer:
Brainliest please!
1. Evaporation - During this process, surface water turns into water vapor. This is done by the transfer of heat energy. Water absorbs this heat energy and turns into its gaseous state.
2. Condensation - Water vapor rises into the atmosphere and is changed into water droplets. When gas is chilled, it turns back into a solid state. These water particles that form in the atmosphere then come together to form clouds.
3. Sublimation - Ice directly converts into water vapor without first converting into a liquid. This process accelerates when the temperature is low or pressure is high.
4. Precipitation - It is the result of evaporation and condensation. Precipitation describes any liquid or solid water that falls to Earth as a result of those two processes. It includes rain, hail, snow, sleet and a bunch more.
5. Transpiration - When precipitation happens, the soil absorbs some of the water. While in the soil, the roots of plants will take in the water and push it towards the leaves where it is used for photosynthesis.
6. Run Off - This happens as a result of precipitation, so it is again, technically not a process. As water pours down, it leads to runoff. This is the action of water running over the surface of the Earth. As water runs over the ground, it can displace the topsoil with it and move minerals along lakes, seas and oceans.
7. Infiltration - This last process happens when water does none of the things stated above after precipitation. Sometimes, some of the water will move deep into the soil. Avoid the plants, avoid evaporation, avoid runoff, everything. The water instead seeps down and increased the level of the groundwater table. It is called pure water and is 100% fresh and drinkable.
