Answer:

C. Sister chromatids separate

Explanation:

During interphase, which is composed of the G1 phase, S phase and G2 phase, the cell grows and replicates its DNA and some of its organelles. During the S phase, the genetic material is duplicated into two sister chromatids, and centrosomes, which are nucleated microtubules that interact with the chromosomes to form the mitotic spindle, are also replicated. Metaphase is the third phase of mitosis, where sister chromatids align in the middle of the cell before their separation into two daughter cells.

Name the three types of population distribution, describe each, and explain the conditions that govern each.
kakasveta [241]

Answer:

Three types of population distribution:

Clumped.

Random.

Uniform.

Explanation:

1. Clumped:

This is the most common pattern of population dispersion.

organisms are clustered together in a group.

This may reflect the patchy distribution of resources in the environment.

2. Random:

This is a typical distribution where individuals do not interact strongly.

The organism has unpredictable distribution.

3. Uniform:

This is the typical environment where individuals compete with each other for scarce resources like water in the desert.

organisms are evenly spaced over the area they occupied.

In the mitochondrial electron transport system, hydrogen atoms removed from nadh ultimately end up as part of __________.
Sergio039 [100]

The answer is water. This occurs through the following reaction. During this oxidative reaction of NADH by O2, the energy expended is used to synthesize ATP from ADP and Pi.  Because NADH generated in the cytosol cannot enter the mitochondrion, electrons and protons from NADH are transferred in by an electron shuttle system.
