Answer:

The 5' end has free phosphate group while the 3' end has free OH group.

Explanation:

Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will be in each cell?
butalik [34]

Answer:

36 chromosomes in each cell

Explanation:

Mitosis is an equational division which means that it does not reduce or change the number of chromosomes in the daughter cells. Mitosis in a single parent cell produces two daughter cells each having the same DNA content and the number of chromosomes is present in the parent cell. Each chromosome after the S phase has two sister chromatids that separate from each other and are segregated to the opposite poles of the cell during anaphase of mitosis. Therefore, a cell with 36 chromosomes will form two daughter cells after one round of mitosis. Each daughter cell would have 36 chromosomes.

Which of the following can occur to two segments of a population if they are geographically isolated
lbvjy [14]

The correct answer is 4.) Eventually they become separate species

A process of formation of a new species from an existing species is called speciation.

When a single species changed into two or more separate species, is called speciation. Speciation can take place due to reproductive isolation.  In reproductive isolation, the separated species no longer can interbreed among themselves. This is happened due to mating differences, sterility or environmental barriers which finally results into the adaptive splitting into two species.

Im so sorry if im asking alot of questions but i dont know anything so can someone help me ?

Answer:

The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.

Examples:

Homogeneous:

Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.

Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.

Heterogeneous:

Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.
