without rain animals would not survive

Answers

Answer:

Without rain, there would more than likely be no collection of water for animals to drink such as ponds, lakes, rivers, etc. Rain, in addition to providing these animals with water to drink, also provides them with their natural habitats such as fish, mosquitoes, and other water creatures. Without rain, animals would merely perish, and soon, humans would as well.

a human red blood cell is placed in a solution whose solute concentration is twice as great as the concentration of the cell cytoplasm. The cell membrane is selectively permeable allowing water but not the solutes to pass through. What will happen to the cell? a.) No change b.) the cell will shrivel because of osmosis c.) the cell will swell because of osmosis d.) the cell will shrivel because of active transport of water e.) the cell will swell because of active transport of water

Answers

Answer:

the cell will shrivel because of osmosis, moving to the region of higher concentration, and it shrivels due lost of water

B is the correct thing. The water molecules with the cell with move to hypertonic solution until an equilibrium is reach . But in this case solute concentration is twice that of the red blood cell therefore the protoplasm of the red blood cell will move further away from cell. Hence the process called crenation (shrivel )

as of may 2020, carbon dioxide levels have reached 417 parts per million. what level should they be at to have the world in a climate similar to that in which civilization first developed?

Answers

Given what we know about global carbon levels in the present and the past, we can confirm that in order to be at the level of early civilizations, the modern-day carbon level should be at 280 parts per million.

Global atmospheric carbon levels are measured in parts per million. What this means is that for every one million units of mass in the atmosphere, 280 of them were carbon. This means that in recent years, the global carbon levels in the atmosphere have doubled.

The primary cause of these increased carbon levels is industrial pollution. Chemicals are released into the atmosphere as a by-product of industrial processess. This began with a noticeable spike during the industrial revolution and has then increased without end.
