The answer is cross-pollination, by using parents that had different traits.

Gregor Mendel researched pea plants and he established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits. In his experiments, he used cross pollination which includes the crossing of parents with different traits. For example, he crossed a plant with green peas and a plant with yellow peas (two different traits) and studied how these traits are inherited to the next generation.

If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population

s344n2d4d5 [400]

Given:

Present population of bison = 3652

Maximum growth rate = 0.28

To find:

The population of bison after one year.

Solution:

The future population can be calculated with the help of the following formula,

$P_F=P_P\times(1+r)^n$

where $P_F$ is the future population, $P_P$ is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

$\Rightarrow P_F=3652\times(1+0.28)^1$

$\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675$

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.

A checkered hen mates with a checkered rooster. The genes for the checkered trait are codominant in both parents. What are the c

seropon [69]

Answer:

Option D, 75%

Explanation:

Let the genotype of co dominant checkered hen mates and checkered rooster be CcC and CcC

Where Cc – is the allele for chekered skin

C – is the allele for non chekered skin

Co-dominant allele are those which irrespective of being dominant or recessive are expressed equally.

The punnet square for the cross between these two would be

Cc C

Cc CcCc CcC

C CCc CC

3 out of 4 offsprings have chekered allele i.e CcCc, CcC and CcC. Thus, the probability of chekered offsprings would be 75%

Water is one of the most powerful forces on Earth. How does the example shown here illustrate the theory of uniformitarianism?

Solnce55 [7]

Answer:

Explanation:

The theory of uniformatrianism was proposed by James Hutton, a Scottish Geologist by profession.

This theory was a contrast proponent to the tenets of the theory of catastrophism in existence before then in the scientific circles

The theory states that "the present is the key to the past and geologic processes occurring today have happened in the times past".

The theory correlates geologic processes as continuous in nature rather can punctuated situations.
Erosion occurring today has been changing the land surface on earth as far back into the geologic times and periods.
From the image, the erosional activities are still continuing today.
