D. organ systems help maintain homeostasis in the body.
What is homeostasis?Homeostasis is the process by which the body maintains a stable internal environment, despite changes in the external environment. This involves the coordination of various systems and processes within the body, including the circulatory, respiratory, digestive, and nervous systems.
These organ systems work together to maintain homeostasis by regulating various functions, such as maintaining a consistent body temperature, pH balance, and fluid balance.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit:
a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer.
b. Explain what happens to the energy that is not transferred from one organism to another.
c. Explain why there are typically fewer organisms at the top of an energy pyramid.
d. Use specific numbers and calculations to support your explanation.
The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.
a)
When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain. This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next. Further deterioration will occur when these herbivores are consumed by secondary consumers. Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.b)
Additionally, the energy flow in a food chain adheres to the 10% law.This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.c)
There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms. Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.d)
For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.learn more about ecosystem here: https://brainly.com/question/842527

What happens during prophase of meiosis I?
Answer:
Meiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.

The word transcribe means 'to write out' and the word translate means 'to express in a different language'. Review the meanings of transcription and translation in protein synthesis. How do the technical meanings of these words relate to meanings of the words in ordinary language.
The word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.
What is the genetic code?The genetic code is a series of instructions that indicate how to synthesize proteins from a given gene sequence.
During transcription, the DNA gene sequence is transcribed into a messenger RNA (mRNA).
During translation, triplets of nucleotides or codons in mRNA determine specific amino acids in the growing protein sequence.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele is 0.72. What percentage of the rats are normal sized? (3 points)
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%
