Frogs have the trait of being the tetrapod.
Explanation:
when the female frogs lays her eggs directly in the water and fertilized eggs are hatched into aquatic tadpoles, on maturity they acquire legs and lungs. tadpoles have tails which is lost during the metamorphosis and the frogs also acquire the carnivorous tastes.
As evident that the male clasps the female from her back and releases the sperm through which the fertilized eggs are laid into water by the female frogs, mature frogs develops the trait of tetrapod. A Tetrapod animal is the one having four pods or four legs. A complete metamorphosis occurs in the life cycle of the frog.
Answer:
Macula densa cells, lower and renin.
Explanation:
Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells. The juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen which is a peptide, or amino acid derivative into angiotensin-1.
Evaporation
Explanation:
Evaporation is one change that would cause more water to evaporate from a stream.
Evaporation is a phase change in which liquid is changed into its gaseous form.
- When a substance is heated from solid to liquid, it melts.
- After melting, additional heat causes a phase change that allows for the liquid to change to gases.
- In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
- This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.

Explanation:
This question requires more information for a complete answer. The first trophic level of a food chain or web is reserved for plants and other photosynthetic organisms that captures solar energy from the sun and converts it to chemical energy. The second trophic level is reserved for herbivores or primary consumers. The third trophic level or secondary consumers are carnivores or predators.
Decomposers are not usually drawn or represented in a food web or chain but they do play a vital role. Decomposers break down dead and decaying organisms and return these unused nutrients to the soil for producers to use.
