Answer:

igneous, sedimentary, and metamorphic

Explanation:

Igneous rocks form when molten rock cools and solidifies.

Igneous, sedimentary, and metamorphic rocks are the three types of rock.
When molten rock (magma or lava) cools and hardens, igneous rocks form. Sedimentary rocks form as particles settle out of water or air, or when minerals precipitate out of water. They build up in layers. Existing rocks undergo metamorphism as a result of heat, pressure, or reactive fluids like as hot, mineral-laden water. The most prevalent elements in the Earth's crust are silicon and oxygen, which make up the majority of rocks.

1 connection between mutations and reproduction

Answers

Answer:

An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.

Explanation:

mutations affect reproduction. if the mutation has a deleterious affect on the phenotype of the offspring the mutation is a “genetic disorder”

tudy the arrow that is circled in the image.

The sun is in the sky. Clouds with blue arrows pointing down toward water. A circled arrow is pointing from the water inland. Red arrows are pointing up from the land to the sky.

What happens at this point?

Warm air is rising.
Cool air is sinking.
There is a difference in air pressure.
Cool air is less dense than warm air.
Dont answer with anything including arrow'S There is no S read it before answering

Answers

Answer:

The blue arrows in circles indicate that cool air is sinking

Explanation:

Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.

So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.

Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.

Cool air is sinking is what that represents

How does the structure of a root hair cell support its function? Explain your answer and I will give brainliest.

Answers

Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.

What are Root hair cells?

Plants do not have a heart, blood, or circulation system, but they do need a transport system to move food, water, and minerals around.

They use two different systems - xylem moves water and mineral ions from the roots to the leaves - phloem moves food substances such as sucrose (sugar) and amino acids from the leaves to the rest of the plant. This movement of food is called translocation. Both of these systems contain cells that make continuous tubes running the full length of the plant from the roots, up the stem, and through the leaves. They are like blood vessels for the plant.

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient.

They also contain lots of mitochondria, which release energy from glucose during respiration to provide the energy needed for active transport.

DNA in the bones used to determine that the first scientist had misidentified the fossil.

What do you mean by fossils?

Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.

There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.

Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber.
