Maurinko [17]
The answer is lower because having to return to a pre disturbance size will likely affect its genetic variation to be lower compared to the original population where in its genetic variation will be greater compared to those in pre disturbance size.

Red-flowering snapdragons are homozygous for allele R1. White-flowering snapdragons are homozygous for allele R2. Heterozygous p
lana [24]

Answer:

a) 1/2 red, 1/2 pink; b) all pink; c) 1/4 red, 1/2 pink, 1/4 white; d) 1/2 white, 1/2 pink

Explanation:

The flower color trait in snapdragons shows incomplete dominance: the heterozygous genotype produces an intermediate phenotype between the two different homozygous genoytpes.

<u>The possible genotypes and phenotypes are:</u>

  • R1R1 : red
  • R1R2: pink
  • R2R2: white

<h3>a. R1R1 X R1R2 </h3>

The R1R1 individual only produces R1 gametes. The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R1R1 (red)
  • 1/2 R1R2 (pink)

<h3>b. R1R1 X R2R2 </h3>

The R1R1 individual only produces R1 gametes. The R2R2 parent only produces R2 gametes.

<u>For that reason, the F1 will be</u> :

  • 100% R1R2 (pink)

<h3>c. R1R2 X R1R2 </h3>

Both parents are heterozygous. This is a monohybrid cross, and from Mendel's Laws <u>we expect the following offspring:</u>

  • 1/4 R1R1 (red)
  • 2/4 R1R2 (pink)
  • 1/4 R2R2 (white)
<h3 /><h3>d. R1R2 X R2R2</h3>

The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes. The R2R2 individual only produces R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R2R2 (white)
  • 1/2 R1R2 (pink)

When unstable elements lose particles and become more stable it is called
Lady bird [3.3K]

Answer:

ions?

Explanation:

If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. ... In an effort to achieve equilibrium, the atom emits particles in the form of radiation until the nucleus is stable. Such unstable atoms are said to be radioactive.

A scientist has chosen to study the motion of clouds in the atmosphere during thunderstorm. Which type of model is most appropri
LenaWriter [7]

Answer:

<em>The correct option is A) computer simulation</em>

Explanation:

Models can be described as as a representation of ideas, events or processes. Models might be mathematical, graphical, visual or computer simulations depending on the type of event being represented.

For studying the motion of clods, a computer simulation will be best because it will make it easier to understand the events related to moving clouds during thunderstorms.

An equation, map or graph cannot be used because neither of them can depict the information for motion of clouds in the atmosphere during a thunderstorm.
