A male grabs the female around her chest with his front legs and clings until she lays her eggs in the water. ... In 2 to 3 weeks the eggs hatch into tadpoles. It can take 3 to 4 months for the tadpoles to absorb their tails, grow legs and develop lungs.
Phagocytes refer to the procedure by which some kind of living cells known as phagocytes engulfs or ingest other cells or particles. The phagocyte may be a free-living one-celled species, like an amoeba, or one of the body cells, like a white blood cell.
In higher species, phagocytosis is mainly a defensive mechanism against infection and invasion of the body by the antigens, that is, foreign particles.
Thus, phagocytosis is illustrated by most types of white blood cells ingesting bacteria, viruses, and other foreign substances.
The correct answer is the fourth option. The magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x is equal to 50x. Magnification is equivalent to the product of the objective power and the ocular lens. Ten times five is fifty.
In all types of chemical reactions, bonds are broken and reassembled to form new products. However, in exothermic, endothermic, and all chemical reactions, it takes energy to break the existing chemical bonds and energy is released when the new bonds form.
Hope this helps :)
Answer:
Active transport requires energy because it is not a passive process. The molecule has to go against the concentration gradient. Hence it requires energy to be carried by the carrier proteins.
The energy is used is ATP, which comes from respiration
