<span>The
most important estrogen is estradiol and the most important androgen is
testosterone.</span>
Testosterone
is the primary steroid male sex hormone. Its function is to control the development
of male reproductive tissues, to promote secondary sexual characteristics to
maintain health (the prevention of osteoporosis for example). It is synthesized
from cholesterol and it achieves its effects by binding to androgen receptors
on different tissues.
Answer:
<em>The fungus can be transmitted through contact and the fungus is deadly to bats.</em>
Explanation:
David Blehert was a scientist who had received a PhD in the field of bacteriology.
David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.
David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
The right answer is Scientists should conduct long-term studies of DNA technology to determine the consequences.
DDT is a potent insecticide: it kills by opening the sodium channels of insect neurons, destroying them instantly, leading to spasms and then death. Some genetic mutations acting on the sodium channels can make some insects resistant to DDT and other insecticides working on the same principle.
The US Environmental Protection Agency has categorized DDT into the B2 class, that is, potential carcinogen for humans. This supports the fact that the insecticide acts on human DNA.
Explanation:
Plants in forest are not supplied with fertilizer by human beings ,yet they get mineral and salt from the dead decaying body of plants and animal found in the forest .Animal die in forest get converted into humus by bacteria and other animals .Sources of energy is transferred from one life to other by different means in this way plants in forest get plant and mineral.
<span>Enzymes
These are characterized by macromolecular natural impetuous with catalysts that quicken synthetic responses. The particles where upon proteins may act are called substrates and the chemical changes over the substrates into various atoms which are their by products</span>
