Answer:
The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.
Explanation:
The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>
The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.
The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.
The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.

Answer: Algae use photosynthesis to convert CO2 and sunlight into sugars and then convert some of the sugars into oil, which can be harvested and converted to biodiesel. 4) 30x more oil per hectare than other plants used for biodiesel such as soybean, oil palms, and rapeseed.

Answer:
Aerobic respiration;this is the process of breaking down of glucose  <u>with Oxygen</u> to generate energy  as ATPs in living cells
Location- Matrix  and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water  i<u>n the presence of  sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast 
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs
