Answer:
D) a genetic bottleneck
Explanation:
Genetic bottleneck refers to the sudden reduction in the population size due to some adverse climatic factors such as natural calamities. It changes the allele frequencies since the survivor population mostly have different allele frequencies than the original population.
In the given example, an earthquake kills 98% of the squirrels. The survivor population exhibits different allele frequencies for the gene responsible for the thickness of stripes. Therefore, it represents a genetic bottleneck.
CTTAAGGAGCTC. You would get this answer because cytosine and guanine are pairs and thymine and adenine are pairs too.
Answer:
Complex carbohydrates are MADE up of sugar molecules that are strung together in long complex chains, complex carbohydrates are found in food like peas, beans, whole grains and vegetables.
Explanation:
Both SIMPLE and COMPLEX carbohydrates are turned into glucose (blood sugar) in the body and are used as energy.
I really hoped this helped some, I tried to make it specific :[
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
