Answer:
According to scientists , water occupies up to 60 % of the human body .
The importance of water in the human body are ;
- Transport
- Formation of bodily fluids i.e. saliva
- Digestion
- Regulates body temperatures
- Circulation of nutrients
Explanation:
The reason why it is important to maintain good fluid balance within and without he cells is because , It can dissolve various elements to make then easily absorbed into other system .There are many fluids which rely on water for volume e.g. blood which is the main component of the circulatory systems , water also regulates the temperature and heart pressure ,
Through electrolysis , fluid balance in the cells can be achieved and it also helps to generate nerve impulses .
Answer:
Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide.
Explanation:
The production will most likely be halted by an inhibitor until the cell needs more to be produced
Answer:
A source from which organisms generally take elements is called exchange pool (option B).
Explanation:
Options for this question are:
- <em>Food web.</em>
- <em>Exchange pool.</em>
- <em>Reservoir.</em>
- <em>Biotic community.</em>
The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.
<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
Answer:
It is called mimicry when a living thing copies the appearance of another living thing as a means of protection.
Explanation:
Mimicry is used primarily by living things as a means for protection and to decrease the chances of the living thing being killed. For example, a frog that is prey to a toad could have bright colors (bright color frogs are often poisonous) that don't mean anything to the frog and it's species, but to the toad, the frog is poisonous and should not be eaten, so the toad does not eat the frog because it is brightly colored.
Without mimicry, the frog would have been eaten because it wouldn't have had looked like a poisonous frog, or something that the toad would avoid.
