Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
Hope it helps ^^
1. oxygen
2. co2
3. co2
4. oxygen
producers: photosynthetic plants
consumers: humans or any life that breathes oxygen
How are each of the spheres connected to the carbon cycle?
biosphere: regions occupied by living organisms need the carbon cycle to survive.
geosphere: is the habitat of the biosphere, w/o the geosphere plants would not be able to perform carbon fixation.
atmosphere: carbon cycle can contribute to global warming.
anthrosphere: involves the external environment and plants, so the carbon cycle is present.
hydrosphere: carbon cycle still happens in submerged plants as sunlight can pass through water.
How is the growing human population going to affect the carbon cycle?
more humans means more carbon being produced. more co2, more cars, more pollution being expelled into the air. Some things that can occur with the carbon cycle include an excess of co2 being present in the air as there isn't enough plants to efficiently remove it from the air, which can lead to co2 buildup in the atmosphere resulting in climate change.

Answer:
glucose and other sugars, ions etc
Explanation:
The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids.
<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration.
There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>
