Sometimes a mutation is beneficial to an organism’s fitness and can be passed on to offspring. what is likely to happen to the mutation over many generations?
any genetic variation will not persist because the mutation is a one-time event.
there is a random chance of the mutation spreading to other individuals in the population.
the mutation will become more common in offspring and increase the genetic variability in the gene pool.
genetic recombination is the only way that variations can be passed on, so the mutation will die out.

The mutation will occur often in offspring and leads to development of genetic variability in the gene pool.

Explanation:

Mutation refers to the process which causes disturbances in the normal DNA pattern.

When such phenomenon occurs over many generations, it will become a common process in offspring and increase the chance of difference in variability in the genetic makeup as well as the gene pool.

It is because, the first stage of mutation appears tedious to the organism.

As it gets transferred from one generation to another generation, the species due to its capability identifies certain ways and exhibit genetic variability due to the mutation.

By this way the mutation will become more common in offspring as their parent have mated in the presence of mutation.

The mutation will become more common in the offspring and increase the genetic variability of the gene pool.

Explanation:

Mutations get transferred from parent to progeny by means of crossing over phase of meiosis only. Thus only germline mutations are inherited and not somatic ones.

Organisms with favourable mutations have more chances of survival. Thus, based on probability, Offspring's of such organisms will tend to show the mutation more than others

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
