The correct answer is: Differentiate

Every cell in a multicellular organism has an identical genome, and yet, there are various cell types. These varieties are the result of highly controlled modifications in gene expression (different sets of genes must be turned on and off).

Cellular differentiation almost never involves a change in the DNA sequence itself. Therefore, different cells can have very different physical characteristics regardless of having the same genome.

<u>Answer</u>: Differentiate

<u>Explanation</u>: Our bodies come from the fusion of two sex cells that provide the us with a full chromosome set specific to our species. Thus, all the cells in our bodies originate from a single diploid cell formed by the fusion of two gametes.

Inside that cell is the complete blueprint for our bodies encoded in our genes. However, as this cell divides, its offspring will start to fullfill different functions (skin cells, smell receptors, photoreceptors etc.). This is achieved by activating only a specific set of genes. The rest of the genes encoding for other cell types are inactive.

Thus, the ability to turn different sets of genes on or off enables cells to differentiate.

Peter and Rosemary Grant observed a small group of the large ground finches that colonized Daphne Major in the Galápagos Islands
erica [24]

Answer:

1) Founder effect and genetic drift: Small colonizing population did not represent the original gene pool of the source population and was more likely to undergo genetic drift.

2) Natural selection

Explanation:

Evolution of the population of the finches with larger beaks might have occurred due to one of the following mechanisms:

a) Founder effect and genetic drift: Since the size of the colonizing population was small, it did not carry all the genes and their alleles present in the gene pool of the original population. The small population size made it more likely to evolve by any chance event.  

b) Natural selection: The availability of different food types in the new habitat led to the natural selection of the larger beaks as the finches with larger beaks might have been able to better exploit the available food resources.

Species A has a diploid number of 42 chromosomes, while species B has a diploid number of 48 chromosomes. Give the chromosome nu
Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
