Crossing over increases genetic variation because due to this, each of the homologous chromosomes get a new combination of traits/ genes and since a each cell has different homologous chromosomes, genetic variotion will occur

Mandarinka [93]

Answer:

gain, rather than lose, heat by radiation.

Explanation:

The body is can lose the heat by evaporation, radiation, conduction, and convection. The sun transfers the heat on the earth through radiation which we absorb and our body temperature rises. The loss of heat from the body through radiation occurs normally when the air temperature is below 20-degree Celcius.

But in tropical regions, the temperature is very high so the gain of heat by radiation is more than the loss of heat by radiation which can lead to heatstroke in those people who do not have sweat glands because in this condition 85% of heat can be lost by sweating.

Which component of bone is responsible for its strength?
Lorico [155]
<span>The answer is osteoid. It begins with unmineralized collagen fibers and ground substance. Later it becomes a calcified matrix. The matrix is mainly made of collagen and calcium ions.   When not well mineralized, osteoblasts proliferates hence the bone will not have the desired strength. This results to deformation of bone causing rickets</span>
