Answer:
B
Explanation:
This involves selectively breeding two or more populations of a species or subspecies with desirable traits that are wanted by the humans. The offspring of the populations will bear the desired traits from the population. Breeding can be done over generations. An example is the breeding a cattle population that is resistant to drought and another that produces more milk. The filial generations will bear both traits.
Answer:
An increase in a population of one species may case the extension of another species with the same food ration.
An introduction of a new food resource into the environment may cause a new species to appear.
An introduction of a new species of predator may cause the evolution of new defenses in some prey species.
Explanation:
An increase in a population of one species causes the extension of another species with the same food preference because the high population specie eat all the food and no food source is available to the other organism. An introduction of a new food resource into the environment may cause a new species to appear due to availability of the type of food.. An introduction of a new species of predator may cause the evolution of new defenses in some prey species which helps them in their survival.
The cerebrum is the largest and most complex part of your brain. It controls all your conscious thoughts and learning,
including setting goals, your memories
and your decisions to act.
It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing . it helps keep the organelles in place and directs their movement as needed . it keeps the DNA safely enclosed in the nucleus and holds the nucleus together . it provides anchoring places for the cell cytoplasm and help it move molecules . maybe that help :)
