Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Hope this helps.
Answer: Insulin is a hormone, which is secreted by the pancreas to regulate the sugar levels in the bloodstream.
Explanation:
Insulin is a protein hormone if take orally, will get digested in the digestive tract, it will not be able to affect the target site of action.
Insulin gets denatured in the digestive tract. Thus it will not be able to control the blood sugar levels.
Nancy has taken the insulin dose orally, the insulin will get denatured in the digestive system, it will not function and Nancy will remain hyperglycemic after the consumption.
Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
A species that is involved in a facultative mutualism with another: can utilize different resources outside of the mutualism.
Explanation:
- Mutualism is a type of ecological relationship in which two organisms are related to each other in such a way that both of them could benefit from the relationship.
- A type of mutualism in which the two organism cannot depend on any other resource outside their mutualistic relationship is called obligate mutualism.
- A type of mutualism, in which the participating organisms can opt for other resources outside their mutualistic relatonship i.e. they are not completely dependent on each other, is called facultative mutualism.
<span>Cell code for enzymes that can convert other molecules into carbohydrates, nucleic acids and lipids. Humans can synthesize 11 out of the 20 amino acids and bacteria can synthesize all 20. Plus bacteria can synthesize many of the vitamins that humans cannot, including vitamin C. As far as humans are concerned, we can make carbohydrates and glycogen from glucose. We use some amino acids to make nucleic acids and we can synthesize lipids and cholesterol from acetyl coA. There are certain types of fatty acids we can't synthesize and we must get them from our diet.</span>
