Answer:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water
Explanation:
please give brainliest
Answer:
Water covers about 71% of the earth's surface.
326 million cubic miles of water on the planet
97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling).
320 million cubic miles of water in the oceans
3% of the earth's water is fresh.
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
0.5% of the earth's water is available fresh water.
If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon).
In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.
This supply is continually collected, purified, and distributed in the natural hydrologic (water) cycle.

It's hard to believe that forces and energies in space have an impact of events here on Earth. Scientists believe that the Sun is a huge influence on our planet. They have evidence to support their theories.
Can you pick out the statements that are true; statements that support the influence of the Sun on the Earth?
Spring tides are the largest tides due to the combined influence of the Sun and the Moon.
The sunspot cycle results in ice ages on Earth.
Solar flares disturb some radio communications here on Earth.
Geomagnetic storms on the Sun can damage to Earth-orbiting satellites.
The Sun's gravity is responsible for the planets' orbital path.

What is the main difference between the two parts of protein synthesis?
A. The first builds RNAs and the second builds proteins
B. The first happens in the presence of oxygen and the second is anaerobic
C. The first requires the input of energy from the cell and the second is passive
D. The first take place in the cytoplasm and the second takes place in the nucleus
Answer:
A
Explanation:
transcription creates mRNA, while translation builds proteins
In the process of protein synthesis, the first builds RNAs and the second builds proteins. The correct option is A.
What is protein synthesis?Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously.
The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription. Initiation, elongation, and termination are its three stages.
Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.
In the first stage, messenger RNA (mRNA) is created. After leaving the nucleus, mRNA moves into the cytoplasm and joins a ribosome.
At this time, the second stage of translation starts, during which a specific protein molecule is created by reading the genetic instructions contained in the mRNA molecule.
Thus, the correct option is A.

Why are phase changes considered physical and not chemical
changes?
Answer:
Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed. ... The phase of a substance depends on the amount of energy the atoms contain. All atoms are in motion. The higher the temperature of an atom, the faster the motion

What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

A rabbit is born with brown(g) fur. It has 9 other siblings from the same
litter, and they all have white(G) fur.
Select the True Statements.
• Brown fur is caused by a mutation
•The dominant allele is G
•The dominant allele is g
•gG is a genotype for white fur
•Brown fur is the recessive trait
•Gg is a genotype for brown fur
•The recessive allele is g
•White fur is dominant over brown fur
Answer and Explanation:
What we know:
1 rabbit born with brown fur (g).
9 other siblings with white fur (G).
The correct answers:
- The dominant allele is G
This is because G is capitalized, and there are more white bunnies than brown.- Brown fur is the recessive trait
We see that (g) isn't capitalized for the brown bunny, and that there was only 1 brown bunny out of the 10 bunnies in total. So, brown fur is a recessive trait.- The recessive allele is g
This is correct because g isn't capitalized, and acts recessive, or doesn't appear unless the genotype is gg, in which the recessive trait will then appear/unhide.- White fur is dominant over brown fur
There is more white fur bunnies than brown fur bunnies, so the white fur trait is dominating the brown fur trait.I hope this helps!

The stars appear to move across the sky every day, but
their paths change throughout the year. Here is a model of
the Sun-Earth system.
Based on the model, which three factors might cause this change in the
apparent movements of the stars?
Answer:
Earth's Revolution around the sun, The tilt of Earth's Axis, and Earth's rotation on its axis.
Explanation:
I have done this test
1. The Earth's revolution around the Sun: As the Earth revolves around the Sun, the stars appear to move across the sky each day. This is because the Earth is rotating on its axis, which causes the stars to appear to be moving from east to west.
2. The Earth's tilt: The tilt of the Earth's axis also has an effect on the apparent movement of the stars. As the Earth rotates around the Sun, the tilt of the Earth's axis changes throughout the year. This causes the stars to appear to move slightly differently at different times of the year.
3. The Precession of the Equinoxes: The precession of the equinoxes is the gradual wobble of the Earth's axis which takes place over thousands of years. This has an effect on the apparent movement of the stars, as the angle of the Earth's axis changes over time. This causes the stars to appear to move in a slightly different pattern than they did thousands of years ago.
