<u>Answer:</u>

<em>Six centromeres are observed in a prophase cell from an insect, there are </em><u><em>20 pairs of chromosomes present</em></u><em>. </em>

<u>Explanation:</u>

<em>Centromeres is defined as the part of the DNA</em> which are held responsible for the directional changing of chromosomes.

And these chromosome gets divided into <em>2 daughter cells while undergoing the process of mitosis and meiosis. </em>

<em>Chromosome is basically defined as a thin structure</em> as of a threadlike which is made out of nuclei acid and protein which is <em>located at the nucleus of various living cells</em>

Answer:

6

Explanation:

In the cell that is in the process of dividing, each condensed chromosome appears as a pair of rods joined at a certain point, the centromere. These two chromosomal “halves”, called sister chromatids are identical and arise from the duplication of the original chromosomal filament, which occurs in the interphase, just before cell division begins.

In summary, we can say that a centromere is the structure that holds a pair of chromosomes together, so if six centromere are observed in a prophase cell, it means that there are six pairs of chromosomes in that cell.

How does ATP release energy that's stored within the molecule? 
Korvikt [17]

Answer:

Option (D).

Explanation:

ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions.

The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone.

Thus, the correct answer is option (D).

A ____ is the underlying combination of genetic material present (but outwardly invisible) in an organism.
Alex

Answer:

D (Genotype)

Explanation:

A genotype is the genetic make up of an organism i.e. what the genetic material

of an organism constitutes. Genotype describes the set of genes contained in an organism's genome. According to Mendel, an organism receives two forms of genes called ALLELE for a trait, one from each parent. The genotype of a specific gene coding for a trait is represented by each pair of allele for that trait.

Although the genotype of an organism is outwardly invisible i.e. cannot be seen, but it determines the phenotype of that organism i.e. the outward appearance. For example, if a plant receives T and T alleles coding for tallness, from each parent. The genotype of that plant for the specific height trait will be (TT). Hence, the TT genotype although invisible but controls the tallness of the plant.
