If no other changes occurred, how would emigration affect the population density of a group of organisms?​

<u>Answer:</u>

<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms. </em>

<u>Explanation:</u>

<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.

Population density is the population per unit area that is population per square kilometer.

Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration.  </em>

With a population in Hardy-Weinberg equilibrium, the A allele has a frequency of 0.60, and the frequency of the a allele is 0.40
valkas [14]

Following the Hardy-Weinberg equilibrium theory, the frequency of the heter0zyg0us genotype is 2pq. In the exposed example, 2pq = 0.48.

<h3>Hardy-Winberg equilibrium</h3>

The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q.

Assuming a diallelic gene,

→  The allelic frequencies are

  • p is the frequency of the dominant allele,
  • q is the frequency of the recessive allele.

→  The genotypic frequencies after one generation are

  • p² (H0m0zyg0us dominant genotypic frequency),
  • 2pq (Heter0zyg0us genotypic frequency),
  • q² (H0m0zyg0us recessive genotypic frequency).

If a population is in H-W equilibrium, it gets the same allelic and genotypic frequencies generation after generation.

The addition of the allelic frequencies equals 1  ⇒ p + q = 1.

The sum of genotypic frequencies equals 1 ⇒ p² + 2pq + q² = 1

If the allele A has a frequency of 0.6, and the allele B has a frequency of 0.4, then the frequency of the heter0zyg0us genotype is

2pq = 2 x 0.6 x 0.4 =<u> 0.48</u>

Select all the correct answers.
Andrej [43]

The first colorimeter (i'm guessing is standard) is less exact then the actual reading, and has a harder time pin-pointing. (it gives a number near the actual temperature, but it is not correct.)

The second colorimeter is exact, and should be 'trusted more in the future', because it gives an accurate reading of the current temperature.

these are the 2 conclusions i got from the top information given to me.

Which of the following correctly pairs an ecological level with an example? Select ALL that apply.A. community - the fish, frogs
ch4aika [34]

Answer:

A. community - the fish, frogs, insects, and aquatic plant species that live in a particular lake

B. individual - a groundhog living in your backyard

C. ecosystem - all of the species of plants and animals and the non-living resources in a tropical forest

Explanation:

A community is defined as a group of populations of two or more different species which inhabit the same area at a certain time.

Individual is defined as one type of organism.

Ecosystem includes communities, the environment, the non-living or abiotic conditions and their influence on living organisms.
