Answers
Answer:
thats crazyyyy
Explanation:
Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.
The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.
The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.
For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

What would happen to a cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute?
Answers
A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.
A hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic
if you place a cell in a hypertonic solution, the cell shrinksit loses water as due to osmosis water moves from a higher concentration inside the cell to a lower concentration outsideThe water will move out of the cell to try to equalize.Thus, A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.

What is dichotomous key?A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.
A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.
The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.
Thus, option D is correct.

Answers
It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.
Nitrogen cycle is the series of processes where nitrogen converts into its compound move through the environment and in living organisms.
The processes here include fixation, ammonification, nitrification and denitrification.Majority of Earth's atmosphere is nitrogen.Nitrogen fixation is the process allows free nitrogen to available for plants.Plants can not use free nitrogen their for they require fixation and nitrogen fixating bacteria in nature.nitrogen fertilizers provide nitrogen for plants in soil therefore it necessary to add a nitrogen-based fertilizer to the soil.Thus, It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.
