Answer: The cause can be something that causes the problem and the effect is what effected it. If something caused the population to go down the effect would be death rate or birth rate.
Hope this helps!
Answer:
Option C
Explanation:
In elephant seals, the male arrive the beach first and start establishing its territory. Once their territory is established female elephant seals starts arriving at the beach and prefer mating with the male who can defend their territory or females in his territory from other males. All females in the territory of specific male mate with the male give birth to their pups and after staying for few months move back into the water.
hence, option C is correct

Explanation:
The cerebrum is the largest part of the brain that contains left and right hemispheres.
The functions of the cerebrum are:
- interpreting touch
- vision and hearing
- speech
- reasoning
- emotions
- learning
- fine control of movement.
The whole brain system has got three parts, which are:
- cerebrum,
- cerebellum
- Brain stem.
Gene Therapy is the name of the process.
Answer:
Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.
It may arise from various factors such as:
- Geographical isolation such as river, mountain, etc
- Behavioral changes such as mating time or season, mating rituals, mating location etc.
- Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.
- Genetic differences.
Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.
These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes
With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
