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.

Substance A's molecules are small. Substance B's molecules, which react with substance A to produce a blue-black color, are larger in comparison. If a solution of substance A is placed inside a selectively permeable bag, and the bag is placed in a solution of substance B, what will happen?
Here's link to the answer:
tinyurl.com/wpazsebu
When A reacts with B, it turns blue-black because the substance A is starch and its molecules are small, which is glucose. The substance B is iodine, which combines with starch to become blue black. If A is present in B, then the A will become blue black.
What is the reaction between the starch and the iodine?
Starch is a polymer that is made up of glucose monomer and is found in plant-based food products. This starch can react with iodine and produce a blue-black coloration, so when the substance A is placed in the substance B with a selectively permeable membrane, the substance B (iodine) can easily enter the starch and form the blue-black coloration. This is known as the starch-iodine reaction, and it results in a blue-black polysaccharide.
Hence, if a solution of substance A is placed inside a selectively permeable bag and the bag is placed in a solution of substance B, then the substance A (starch) will turn blue-black.

Which of the following data would support the claim that the gravitational force
between objects depends on mass?
O An object's weight can change depending where it is on Earth.
O A rocket can escape Earth's gravity by traveling at high speed.
O The further a planet is away from the sun, the smaller the gravitational force.
O Gravitational force is stronger on more massive planets.
Answer:
D.
Explanation:
gravitational force of attraction is stronger on more massive planets such as Jupiter
Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.
What is gravitational force?The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.
Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.
In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.
Therefore, gravitational force is stronger on more massive planets, hence option D is correct.

What might happen to a desert biome if the area received more rain than it normally receives over an extended period of time? Describe some of the changes that you might expect to see
Answer:
Desert biome will change.
Explanation:
Desert biome will change if the area received more rain than normal it receives over an long period of time because the vegetation on that area appears. The change in rainfall pattern in the desert area changes the animals present in this region because the temperature of the desert is no longer suitable for the desert animals so they migrated and other organisms come to this place.

Save Answer
Answer:
The correct answer would be - AUGCUUAUC
Explanation:
The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.
Original strands: TACGAATAG
new RNA strand: AUGCUUAUC

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
