Answer:
Option 4 - Calcium
Explanation:
The <em>divalent cation </em>called <em>calcium</em> is needed to provide additional support to the bone matrix.
Calcium is considered one of the most <em>important components</em> in bone development. It helps in the formation as well as maintenance of bone. During the modeling and remodeling process of bones, calcium facilitates the formation of <em>semi-hard new tissues</em> which leads to the formation of new bone which is very hard.
Due to this reason, calcium is needed to create extra bone matrix support.
Answer:
The body will overheat
Explanation:
If the brain of an individual does not receive input that the body was starting to heat up on a hot day, <u>the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating. </u>
Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding.<em> Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.</em>
Answer: Option B and C.
Heavy and continuous rains flood the land, submerging habitats.
c. Lightning strikes a tree and begins a fire that clears the land.
Explanation:
Heavy and continuous rains flood the land, submerging habitats.
Lightning strikes a tree and begins a fire that clears the land.
The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.
Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.
Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.
Therefore, Heavy and continuous rains flood the land, submerging habitats.
cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
