Mitochondria contain their own genome and duplicate by fission. even so,Mitochondria cannot function for long when isolated from the rest of the cell because they are endosymbionts.
Organelles called mitochondria are focused on cellular respiration, which is how a cell gets its energy. Mitochondria and other organelles are found only in eukaryotic cells; they are absent in prokaryotes.
Endosymbiosis, in which one cell was swallowed by another and eventually started to function within it, is the theory put forth by scientists as to how mitochondria evolved. In exchange for other functions of metabolism, mitochondria produce energy in a symbiotic relationship with cells. Thus, mitochondria are dependent on their host cell for survival.

In the form of DNA.........
The numbers of producers will be greater than the number of consumers.
Answer:
The correct answer is A. Actin filaments would grow longer.
Explanation:
If the monomers added bind nonhydrolyzable ATP, then, the interactions between each monomer will be more stable causing the filament to grow longer as it's really stable without the hydrolyzation of ATP.
Answer: These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.
The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries.
In exocytosis, a cell releases substances into its environment. During exocytosis, vesicles that contain substances are moved to the cell membrane and fuse with it. This cell membrane function has three results: the total surface of the membrane increases, toxins or waste products are eliminated, and proteins become part of the plasma membrane.
