Answer: Flagellated sperm

Explanation:

Mosses are generally in the class of non-vascular plants and ferns are vascular plants that are non-seed bearing. They both produces gametophyte that come in the form of spores, rather than seeds.

Flagellated sperm: These type of sperm will come together with egg cells in the presence of water to produce spores, instead of seeds.

Most of the times in the cases of mosses, the spores are produced on stalks which are above the low-growing vegetative portion of the plant. While in the instances of the ferns, the spores are basically produced in tiny spore cases along the back side of the leaves.

The feature of endocrine system that makes it distinctly different from the nervous system is that it uses hormones distributed through the bloodstream, option(A).

<h3>Why is endocrine system distinctly different from nervous system?</h3>
  • The biggest difference between these two is that the endocrine system uses hormones produced by glands into the bloodstream, whereas the nervous system uses electrical impulses to send signals through neurons.
  • The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are short-lived when compared to endocrine system.

Therefore, option(A) is the correct answer.

To know about differences between the two systems, refer:

In the diagram, how many angles are alternate exterior angles with angle 5?
andriy [413]

Explanation:

We have attached a figure that shows the diagram of the given equation.

We need to find how many angles are alternate exterior angles with angle 5?

We know that an exterior angle is the angle that is made outside of the shape and an alternate angle is the angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.

Use this information to answer questions 6 - 11. Your original population of
grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6
