I am taking this now It says in my course, A. Number of organisms.
Answer: Cell membrane is layer which is present in all living cells. It is present under the cell wall but in some cases such as plant cells.
Explanation: It is composed of lipid bilayer and proteins embedded in it. Phospholipids, glycolipids and sterols is the composition. Its function is to protect the cell from extracellular environment. It is semipermeable membrane that js allow only selected molecules to pass.
This is called the endothermic mechanism found in most organisms.
Endothermy is a physiological characteristics that enables some animals to control their body temperature unlike exothermics. This mechanism is important due to sudden change in temperature or uncontrollable conditions set by the harsh environment.
<span>So birds sharks salamanders and other related animals have this function.</span>
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
Of the object has a big amount of density
