Which of the following does not accurately describe movement within plants?

1 answer:

3 0

A. Transpiration is the only force that drives water movement within a plant.

<span>Normally there are two kinds of roots and they are taproot and fibrous roots. In case of taproots the main root goes downwards and smaller roots branches out of it. In case of taproots, it is true that the spread of roots is smaller than the depth of the roots. In case of fibrous roots, the spread of roots is greater than that of the depth of the roots. A wig tree is an example of a plant having taproot. in the wig tree the root can go to a depth of around 120 meters.<span>

prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

$p^{2} + 2pq + q^{2} = 1$

$(0,3)^{2} + 2pq +(0.7)^{2} = 1$

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

Answer:

The CNS

Explanation:

First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.

larisa86 [58]

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

The green beetle increases its survival rate (fitness) each year

The brown beetle decreases its survival rate each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.
