Where is Earth's Water?

"Water, Water, Everywhere...."

You've heard the phrase, and for water, it really is true. Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.

For an estimated explanation of where Earth's water exists, look at this bar chart. You may know that the water cycle describes the movement of Earth's water, so realize that the chart and table below represent the presence of Earth's water at a single point in time. If you check back in a million years, no doubt these numbers will be different!

Left bar: All water, freshwater, and saline, on, in, and above the Earth.

Center bar: All freshwater

Right bar: Only the portion of freshwater residing in surface water (rivers and lakes, etc), snow and ice, and relatively-shallow groundwater.

Here is a bar chart showing where all water on, in, and above the Earth exists. The left-sidebar chart shows how almost all of Earth's water is saline and is found in the oceans. Of the small amount that is actually fresh water, only a relatively small portion is available to sustain human, plant, and animal life.

Bar chart showing the distribution of water on, in, and above the Earth.

Sources/Usage: Public Domain.

Notice how of the world's total water supply of about 332.5 million cubic miles of water, over 96 percent is saline. And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Fresh surface-water sources, such as rivers and lakes, only constitute about 22,300 cubic miles (93,100 cubic kilometers), which is about 1/150th of one percent of total water. Yet, rivers and lakes are the sources of most of the water people use every day.

This type of mutation is The normal sequence of genes along a hypothetical chromosome is ABC*DEFGH, where letters represent genes and the asterisk (*) represents the centromere. A mutation event results in a chromosome in which the sequence of genes is ABC*DGFEH. This type of mutation is :

a. A point mutation.
b. A translocation.
c. A nonsense mutation.
d. A duplication.
e. An inversion.

Answers

Answer:

The correct option is e

Explanation:

An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.

From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.

NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.

Which factor is a major cause of the changes that
occur during puberty, the years when the rate of
human physical growth increases and reproductive
maturity occurs?

A) changes in some hormone levels
B) an increase in meiosis in body cells
C) a decrease in the rate of metabolism
D) change in the gene sequences in reproductive
cells

Answers

The changes that occur during puberty are mostly a result of changes in hormone levels in the body.

Puberty

The transition from a child to an adult is caused by changes in the level of some hormones in the body.

In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.

In males, there is an increase in the production of testosterone hormone among many other hormones.

Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

Answers

It could be possible to have the same species of penguin living in multiple geographic locations due to the process of adaptation.

What is adaptation?

Adaptation refers to the characteristic of an organism that helps them to survive better in the surrounding environment. Living organisms are adapted to the habitat they live because they have built special features that help them to survive.

So we can conclude that it could be possible to have the same species of penguin living in multiple geographic locations due to the process of adaptation.

Explanation:

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences are due in part to genetic differences, predict what will likely happen to the songs of the two frog populations.

a. The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
b. The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.
c. This data does not help us understand effects of gene flow on fitness. The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.
d. You cannot predict a change in the courtship songs at the two lakes.

Answers

Answer:

I am pretty sure that the answer is B or D

Explanation:

a decline in fitness doesn't really make sense, because we are talking about courtship songs, not health. C.) doesn't make sense either, because at the end of the sentence it says that the fitness of the population is growing. again, we are talking about songs. Both b and d make sense.
