Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.
Answer:
behavior is considered the result of an interaction of genes and environment. For example, the development of intelligence depends on both the genetic influences on the brain and the environmental influences that affect learning in the child. Nature and nurture work together in behavior
Explanation:
Answer:
The correct order is
E. Adsorption
B. Penetration
D. Synthesis
A. Assembly
C. Lysis
Explanation:
Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.
The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.
The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
The best answer is A
Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.
Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.
To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.
There are so many examples for that in different areas, like biology experiment carried out in our lab recently.
