Answer:
The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.
Explanation:
The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>
The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.
The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.
The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
<h2>Muscle contraction in cytoplasm </h2>
Explanation:
- Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
- ATP is basic to get ready myosin for official and to "revive" the myosin.
- When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
High-residue cover cropping is an adaption of conservation tillage in which a high-biomass cover crop is grown during the winter and is rolled or cut down prior to no-till or strip-till planting in spring.
Eye spot allows to some protists to detect light. eye spot receiving light stimuli. eyespot which is a light sensitive organelle, which helps the chlamydomonas to swim toward the light. eyespot is also called the stigma. the eyespot is similar to an eye of human. it helps organisms pick up light waves to help the organisms live and function.
