How does the structure of a root hair cell support its function?

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.

Answer: B: Luster and Conductivity

Explanation:

The circuit is to test conductivity and the light is to test the shine or luster. :-)

i heard it had to do something with DNA in the bones all animals that where fossalized where identafied by using the DNA in their bones

hope that helped

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

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.

Explanation:

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:

Answer:

e rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. ... The best way is to use a hand crank such as a hand cranked flashlight or radio because it is easy to power enough energy for a short amount of time.

Explanation:

Answer:

yes because a thermodynamic system (isolated system) enclosed by rigid immovable walls through which neither mass nor energy can pass.

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 to provide the energy needed for active transport.

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.
