Independent
Explanation:
A density dependent factor would cause a downfall to the population based on its numbers, like a disease. A density independent factor would affect it regardless of the population size, such as a storm or cold winter.
The answer is B. both need food and air
Answer:
It's the tundra
Explanation: I say that because the tundra, which literally means "treeless plain," is the coldest biome. Extremely low temperatures, limited precipitation, a short growth season, minimal biodiversity, and nutrients in the form of decaying organic matter are all characteristics of tundra.
Overproduction is a natural phenomenon in which the number of produced offspring is higher than the number of individuals the ecosystem can sustain. Thus, competition for limited resources occurs.
Because of the genetic variation, the organisms within a population have different chances to reproduce. Most often, some organisms have a lower reproductive success than others do.
The number of individuals with a high reproductive success is rather low as few males are very successful at passing on their genetic material.
The number of organisms with no reproductive success is also very low, as these "ill adapted" individuals will disappear from the population extremely quickly.
Genetic variation is the amount of differences between individuals. Thus, no organism taken by itself has any genetic variation.
Answer:
Their future children can have blood group AB, O, A or B
Explanation:
since the husband had blood group= Heterogeneous A means AO
and,
the wife's blood group= Heterogeneous B or BO
- so by crossing between them, we get this result.
