It is necessary for
nurses to join programs about growth and development because this is essentially
what they are dealing with everyday. Since they deal with different age groups,
growth and development is important to know what is normal in all age groups in
order to identify possible abnormalities their patients might face.
The scrotum is the sac that regulates the temperature of the testes and maintains its at 35degrees celsius. This temperature is 2 degrees lesser than that of the normal body temperature because, at higher temperatures, the process of spermatogenesis is affected. Temperature regulation is done by the smooth muscles of the scrotum.
<u>Answer</u>:
<u>Question 1.</u> 1.fragmentation The roads act as barriers which cannot/or will not be crossed by many forest dwelling species. They are either physical or psychological barriers for animals. The presence of humans and cars further increases this effect. Thus, the original forest habitat becomes fragmented into smaller areas with smaller populations.
<u>Question 1.</u> 2.find an unrelated mate
As the forest becomes fragmented, the original area and population of a species is divided into smaller units. Thus, for the individuals belonging to such a diminished population, the chances of finding an unrelated mate will decrease rapidly with time. This will lead to inbreeding and a loss of genetic diversity.
Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:
Explanation:
Transpiration is the loss of water from plants (via their leaves).
Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).
Animals excrete water by respiration and by passing urine.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
