Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.
Answer:
C
Explanation:
Generalist predators. Generalist predators have, by definition, several alternative prey species between which they may 'switch', depending on which prey species are currently most abundant.
No i don't think so; this is because in a particular energy pyramid, no additional energy enters the system, and energy is lost to the environment at energy level. An energy pyramid is the pyramid that shows the availability of energy that connects the consumers with the decomposers shows the energy transfer between trophic levels. It shows that less and less food and energy is available as you go from the base to the top of the pyramid.
Answer:
Warm air rises on land and moves toward the ocean to cool
Cool air moves from the ocean to be warmed by the land
Explanation:
The land heats up faster than the oceans during the day. This is because water has a high heat capacity and takes more energy to raise its temperatures by one degree (even in comparison to land). Therefore land heats up the air above it faster than the oceans. The air mass over land rises due to drop in density. The cooler and denser air mass above the oceans moves towards land to replace the rising warm air. This creates a cool breeze felt on land during the day as the cool air rushes in.
