Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
Cytokineses completes in telophase.
<u>Explanation:</u>
cytokinesis is the process by which the cell cycle takes place by dividing the cytoplasm. In a cell, mitosis is always accompanied by cytokinesis In a typical cell, although in some cells like Drosophila embryosand vertebrate osteoclasts mitosis takes place without the process of cytokinesis. Cytokinesis usually starts in anaphase and completes in telophase, thereby reaching completion and there is a begging of next phase called interphase.
Telophase is the last completed stage of mitosis. The name is derived from latin word telos which means end. At this phase the sister chromatids will be reaching the opposite poles. the dissolution of the kinetochore microtubules and the continuous elongation of the polar microtubules occurs at telophase.
I'm guessing for no reproduction of other human beings
The result shows that one can be conditioned by experience to have aversion for some food.
In the study of taste aversion, the rats that are shocked during exposure to light and clicker developed aversion for light and clicker sound.
Those rats that were nauseated as a result of sweetened water developed aversion for sweetened water.
