Answer:
Cyclones are actually water born storms in the equatorial regions.
Mainly, water near this equator get heated up as it receives direct sunlight, the hot air rises up and to fill this empty space cold air from poles rush to these equatorial regions. And hence the cyclones are mostly formed in Equatorial regions.
The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body.
Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
Answer:
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
- An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.
- The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
<em>the correct option for this is B>></em>
Answer:by being produced in the testes outside the body
Explanation: spermatogenesis is the production of male gamates,the sperm.this process occurs in the seminiferous tubules in the testes.epithelial cells produces the primary spermatocyte which divides to give a secondary spermatocyte.
The secondary spermatocyte divides to form spermatids,which differentiates to form the spermatozoons.
Testis is housed in the scrotal sac.
Sperm production is sensitive to temperature. Too high temperature can cause formation of abnormal cells . As a result the scrotal sac is located outside the body
