River systems on the western side of the rocky mountains flow into the pacific ocean/ river systems on the eastern side of the r

GalinKa [24]

Option B i.e A Divide is the correct answer.

The Rocky mountains are also called a Divide or Continental Divide of Americas because these mountains separate river system flow in the pacific ocean and the river system which flows in the Atlantic ocean. The Continental divide is also called as the Great Divide.

In humans, six fingers (f) is the dominant trait; five fingers (f) is the recessive trait. if the father is heterozygous for six

rodikova [14]

The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.

<h3>How to calculate genotype of a cross?</h3>

According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.

If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:

Ff
Ff
ff
ff

This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).

In one of the first steps in Prophase I of meiosis,

Vikki [24]

Answer:

D) homologous pairs of chromosomes form tetrads

Explanation:

During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir

azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.
