What percentage of our usable freshwater is already polluted?
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.

When wax is heated, it turns into a liquid. How are the wax molecules affected by this change of state?
answer:
the molecules gain more energy and the space between the molecules increases
explanation:
when wax is heated, the molecules of wax gains kinetic energy and move about randomly until the inter molecular forces binding them together is broken and the wax turn into liquidIn the liquid state, the molecules have more free movement, so they spread out and the distances between them increasecredits: https://brainly.com/question/2755409At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides? A. The number of organelles doubles. B. Chromosomes must be copied. C. Four nuclei must be formed. D. The membrane thickens.
Answer: The correct option is B.
B. Chromosomes must be copied
Explanation:
This is because, before mitosis occurs the cells must first duplicate or replicate it's DNA during interphase and this is because mitosis is a type of cell division where a parent cell divide into two daughter cells which are genetically identical to the parent cell and carry the exact number of chromosomes of the parent cell.

How does the carnivorous plant catch its victums?
Pitfall traps (pitcher plants) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria. Flypaper traps use a sticky mucilage. Snap traps utilise rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum.
Answer:
They use special traps that are connected to them.
Explanation:
For example, the Venus Flytrap uses it's "mouth" to close on the fly. A sundew plant uses sticky spines to stuck to the bugs and slowly curls up and digests the bug.

Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.

Which term best describes two predators living in the same habitat who feed on the same prey?
A.coexistence
B.mutualism
C.competition
Answer:
The answer is C, competition
Competition refers to the interaction between the organisms to seek or feed on the same resource.
The term that best describes the two predators living in the same habitat feeding on the same prey is competition.
Competition can be defined as:
Competition in an ecosystem or habitat will take place when the ecological niche of organisms overlaps as both organisms try to use the same resource. In habitat, the predators feeding on the same prey will have competition, as the predators will fight for food, nutrients, and a source of energy to survive. Competition can be caused among animals due to food, space, and shelter.
Thus, the correct answer is Option C.

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.
