Answer: One way of creating a variation in a population is through genetic replication errors. This will make a new type of alleles. Environmental factors cause variation such as affecting enzyme activity and function. The changes would show in the phenotype of an organism.
Explanation: thus is one way ik for sure another way idk srry
Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.

yes
Explanation:
thornless roses are often a result of a natural mutation that results in a chimera
Answer:
Water added
Explanation:
The above option is the best that represents the missing step.
This process is known simply to be cellular respiration. It is also the reverse of photosynthesis.
In this process, food is broken down in a chemical reaction with oxygen. As this process occurs, carbon dioxide and water are the products. So, in this process, water is added as the product of the breaking down process.
Respiration is seen to be almost the exact opposite of photosynthesis. These two reactions help to maintain biological energy balance on earth.
Answer:
C) The smaller population will be more affected than will the larger population, because the smaller population has less genetic variation than the larger population has.
Explanation:
Genetic variations are present in the natural populations. Some of the genetic traits become adaptive under the changed environmental conditions and allow the individuals carrying them to survive and reproduce. In this way, the genetic variations help to maintain a population.
Therefore, a larger population of a squirrel species with more genetic variations will have less intense impacts of a disturbance/natural calamity and/disease. On the other hand, a smaller population of the same species with a lesser number of squirrels has fewer genetic variations. This population is more likely to be affected in a negative way by a disturbance such as pathogen.
