Why does the land around an once active coal mine remain barren?

Answers

Answer 1
Empty coal mines are flooded with acid rain so no life forms can survive.
Answer 2

Answer:

The ground where the coal was mined is acidic so few plants can grow there.

Explanation:

Usually, the ground surrounding the coal that is mined has a low pH.

Answer:

You can separate them according to the shapes of their beaks.

Some have longer, pointier beaks whilst others have flat and short beaks.

This is because they eat different things: seeds vs worms and insects.

This means that the shape of their beak is an adaptation (it enables their survival) because it makes it easier for them to consume food.

This is known as occupying different niches in the habitat, because even if they all live in one area, they will eat different things, meaning that they will always have enough food to survive.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?

Answers

Answer:

the sun because energy from the Sun heats the Earth unevenly. As a result, convection currents develop in the atmosphere and ocean. These redistribute heat in the atmosphere and oceans.

Answer: Hydropower is created when rapidly flowing water turns turbines inside a dam, generating electricity. Nuclear energy is produced at power plants by the process of nuclear fission. The energy created during nuclear reactions is harnessed to produce electricity.

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?

Answers

Answer:

I hope this will help

Explanation:

When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.

Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

In which of the following would competition not occur?
A Rabbits grazing in a field
B Owls and foxes hunting for mice
с Daisies and dandelions growing in a lawn
D Algae and fish in a loch

Answers

Answer is D

A- competition. Rabbits both want grass so it is a competition depending on how much grass there is.

B- competition. Owls and foxes hunting mice is considered two predators hunting, competition for food again.

C. Competition. Even plants don’t get along. Most plants need sunlight to stay alive and weeds grow quickly. The weeds are more or less silently fighting over the yard to keep growing.

D. Not competition. Algae is an underwater plant that most water life tend to feed off of. In this situation the fish would be eating the plant such as how the rabbits ate the grass, there would only be competition if there was less Algae and more fish. But in this case there is Algae and one fish.

Sorry if it sounds confusing but D is the correct answer

Mitosis vs Meiosis, someone help me with this, ill give brainiest.

Answers

Mitosis: chromosome # stays same in each cell, purpose is to produce more body cells, creates 2 identical sister cells
meiosis: purpose is to produce sex cells for reproduction, creates 4 genetically different cells, chromosome # cut in half in new cells
Both: cell division, dna copied during interphase, start with parent cell
Points of differences between Mitosis and Meiosis:1. Nuclei

Mitosis gives two nuclei, and hence two cells while meiosis gives four.

2. Cells

Mitosis gives identical cells to each other and to the mother cell while meiosis leads to genetic variation due to crossing over and independent assortment.

3.Division

Mitosis includes one division while meiosis includes two.

4. Crossing over

It takes place in Meiosis while absence in Mitosis.

5. Chromosomes

Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes)

A new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction. true or false

Answers

Answer:

True

Explanation:

It is true that a new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction.

This happens due to physical separation of members of a population.

Geographic isolation :Geographic isolation occurs when populations are separated by geographical barriers like rivers, mountain etc.

The population is separated from exchanging genetic material within the same species and results in evolution of a different trait.

What layer of the Earth does the upper surface of the cross-section represent? Group of answer choices Inner Core Outer Core Mantle Crust

Answers

Answer:

Hello! Your answer is...

The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth. The crust is the layer that you live in. The Outer and Inner Cores are hotter. The temperatures of the crust vary from air temperature on top to about 1600. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.

What is the upper surface of the cross-section of Earth?

The rocky exterior of the Earth is known as the lithosphere. It is composed of the uppermost layer of the upper mantle and the brittle crust. You live in the crust of the earth. It is hotter in the outer and inner cores.

The crust varies in temperature from the top air temperature to roughly 1600. The Earth's tectonic plates are moved by the asthenosphere, a region of the mantle.

Therefore, Mantle Crust layer of the Earth does the upper surface of the cross-section represent.
