The answer would be B. The available energy would decrease from the mouse to the hawk. As the trophic level goes up the energy decreases because some of the energy is lost in the form of heat for every energy transfer. This energy being lost cannot be used by the organisms on the next level.
Answer:
Pelvic body cavity
Explanation:
There are four basic body cavities
The dorsal, thoracic, abdominal and the pelvic body cavity. For the question, the sperm can find itself inside the pelvic body cavity, the pelvic body cavity encapsulates the reproductive organs and the bladder. The reproductive organs then includes the vagina, uterus, and fallopian tubes (oviducts) etc. Thus, the sperm can pass through organs of the reproductive system in the pelvic body cavity.
The answer is hyperosmotic urine.
A counter current mechanism system refers to a process, which spends energy to produce a concentration gradient. It is witnessed broadly in nature and mainly in mammalian organs. For example, it can signify towards the process of urine concentration, that is, the generation of hyperosmotic urine.
The hyperosmotic urine exhibit greater osmolarity in comparison to the blood. The kidneys generate hyperosmotic urine in response to a deficiency of water as an effort to return to homeostasis.
Observations are used with observing, forming a hypothesis, and analyzing data.
