Answer:
One biotic factor includes soil, air(oxygen and carbon dioxide), water.
One biotic factor includes animals and plants.
Both factors are different in each ecosystem. This is because, for example, the soil in desert ecosystem can differ from the polar ecosystem. Animals in polar ecosystems include polar bears, wolves, etc. while desert ecosystems have animals like deer, artic fox, etc.

Which of these best describes the difference between forest soil and sandy soil?
A:forest soil is lighter in color than sandy soil
B:forest soil has less humus than sandy soil
C: forest soil has more moisture than sandy soil
D:forest soil supports plant life, but sandy soil does not support any plants.
Explanation:
should be more moisture
Forest soil is the appropriate soil for the vegetation.Options C and D are correct.
What is the reason for good vegetation in forests ?The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life.
Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.

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.

Explain your answer well and I shall give brainliest. How does the structure of a root hair cell support its function?
A group of scientists wants to observe the adaptation of a foreign fish species in a river ecosystem. To do this, they want to enclose the top and sides of a section of a river to block light and matter from entering the area. Evaluate whether this experimental system is an isolated system. Justify your answer based on the definition of an isolated system.
Answer:
yes because a thermodynamic system (isolated system) enclosed by rigid immovable walls through which neither mass nor energy can pass.
How does the structure of a root hair cell support its function? Explain your answer and I will give brainliest.
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.
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. 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.

Explanation:
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
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.
