The work of Charles Darwin and Alfred Wallace on the origin of the Earth's species extended the ideas of Lyell's uniformitariani

sm into the biological sciences. The theory of evolution is based on the principle that the diversity seen in the Earth's species can be explained by the A) random variation in the genetics of any population. B) idea that in any population, too many individuals are produced. C) uniform modification of genetic traits over long periods of time. D) sudden change in the gene pool due to mutations within the DNA of a given population.

<h2>The work of Charles Darwin and Alfred Wallace </h2>

Explanation:

C) uniform modification of genetic traits over long periods of time.

The theory of uniformitarianism  states that the natural phenomena and laws that are bringing about changes in the today's world are functioning in the same rate since the geological times. This idea of uniformitarianism was linked to biological sciences because according to Darwin and Wallace's observation, the uniform modification of genes among the population brought about the species diversity on the Earth.

Why is having a large surface area<br> important for a cell?
grandymaker [24]

Answer:

One beneficial result of a cell having a larger surface area is its ability to cover more area increasing the likely hood of nutrients coming in contact with the cell membrane. Which in turn will increase the rate at which nutrients diffuse through the cell membrane.

HELPP PLSSS :) American pikas are prey to long-tailed weasels. Which change in a limiting factor would increase the carrying cap
Damm [24]

Answer:

A. increase in American pika population size

Explanation:

Carrying capacity is the idea that relates to how much population can an environment sustain before collapsing. Here, the answer would be A. increase in American pika population size  because if you increase the food for weasals, naturally the population carrying capacity goes up because now the environment has food to feed the weasals which can contribute to increasing the carrying capacity (i.e. the environment can now handle larger population of weasel than initial condition)

In one generation, the frequency of the A allele is 70 percent and the frequency of the a allele is 30 percent. What are the cha
Fynjy0 [20]
The answer is 9%.

To calculate this we will use some <span>formulas of the Hardy-Weinberg principle:
</span><span>p² + 2pq + q² = 1 and <span>p + q = 1
where:
</span></span>

<span>p - the frequency of the A allele.
q - the frequency of the a allele.</span>

p² - the frequency of dominant homozygote (with AA genotype)

2pq - the frequency of heterozygote (with Aa genotype)

<span>q² - the frequency of recessive homozygote (with aa genotype)</span>

<span>We know:</span>

p = 70% = 70/100 = 0.7

q = 30% = 30/100 = 0.3

We need to calculate the frequency of the genotype aa:

q² = ?

Since we know the frequency of allele q, it is easy to calculate the frequency of the genotype aa:

q² = 0.3² = 0.09 = 0.09 · 100% = 9%
