Please can I get some help on this? please?
1. If the ecosystem is balanced, which populations should be the largest? Which should be the smallest?
2. Why can the wolf be considered both a secondary consumer and a tertiary consumer?
3. If the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?
4. Analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? What would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? Describe how each level would be affected if each of these changes occurred.
Answers
Answer:
1. producers are the largest and consumers are the least
2. because wolves feed on both primary and secondary consumers
3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.
4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.
if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

What is the critical mass of a species?
A:The weight of all representatives of a species.
B:The weight of the last representative of a species.
C:The number of individuals that must exist for a species to continue.
Answers
Answer:
The number of individuals that must exist for a species to continue
Explanation:
I just had it on a quiz. Can I have brainliest?
The critical mass of a species is the number of individuals that must exist for a species to continue. Therefore, the correct option is C.
What is the critical mass of a species?The critical mass of a species refers to the minimum number of individuals that are required for a population to maintain its viability and continue to survive and reproduce in a given environment. This is also known as the minimum viable population (MVP) size.
The concept of critical mass is important in conservation biology because small populations are often more vulnerable to extinction due to genetic factors, environmental fluctuations, and other factors.
Therefore, understanding the critical mass of a species is significant for determining appropriate conservation strategies and protecting endangered species. Therefore, the correct option is C.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answers
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answers
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
