A cell wall, because animal cells have a cell membrane, ribosomes are used to reproduce some proteins same goes for mitochondrias.
I think under the influence of Antidiuretic hormone (ADH), more concentrated urine is produced. Antidiuretic hormone also called vasopressin acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney increases. It also helps to control blood pressure by acting on the kidneys and the blood vessels.
Protists are least similar to bacteria because all the others are eukaryotic cells. Bacteria are prokaryotic.
Answer:
decomposer decomposes :) so it breaks down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down. dead plants and animals would be everywhere and new organisms couldn't be born/grown. mold breaks down dead organic matter like dead trees. as the result simple compounds come into existence and can be assimilated by plants
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
