Asexual reproduction is not a source of genetic variation.

Further Explanation:

A given population can contain different individual with different sequences in DNA. This difference in DNA sequences between the individuals of the same population is known as genetic variation. Genetic variation can occur both in somatic cells as well as germ cells. The major reasons for variations can be mutations and recombination.

The alteration of DNA sequence which can be caused due to error during replication is known as mutation. Mutations can be either point mutation or frameshift mutation. The mixture of genetic material that a person gets from his family is one major source of genetic variation which is termed as the recombination. Sexual reproduction leads to genetic variation.The offspring arising from a single organism without the involvement of fusion of gametes is known as asexual reproduction. There is no chance of genetic variation because there is no chance of recombination. This type of reproduction is usually common and prokaryotes. The types of asexual reproduction are; fission, budding, vegetative propagation, spore formation, fragmentation, parthenogenesis, apomixis and nucellar embryony etc.

There are some organisms which follow both the asexual and sexual reproduction. This ability e is known as heterogamy. Depending upon the conditions this alteration mainly in the rotifer species.

Answer:

D. Asexual reproduction

Explanation:

In the process of asexual reproduction a new organism is produced from a single parent organism. So the new offspring inherits all the genetic traits of a single parent, there is no recombination of genetic traits. However, in sexual reproduction there is recombination of genetic traits so the offspring shows genetic variation.

Which choice describes a population? A. all the gray squirrels that live in a forest B. a nonliving factor in an organism's envi

goldenfox [79]

I believe D. because all the organisms that live in a lake can be a bunch of living things that would be considered a population and not a species. I canceled out B. from the get go because, I don’t believe non living organisms can be in a population ?

What causes the biggest change mass or speed?

Norma-Jean [14]

Answer:

Explanation if an object is in motion and more force is applied to it, the object will begin moving faster. If two objects have the same mass and a greater force is applied to one of the objects, the object which receives the greater force will change speeds more quickly.:

What happens when energy is released during atomic fission

Vesnalui [34]

Nuclear energy is called the energy obtained by the transformation of atomic nuclei, so small and heavy clusters of particles inside the atom. Nuclear energy can be produced in two ways, by cleavage or synthesis of nuclei. Heavy nuclei of radioactive elements such as uranium or plutonium, can be split into two nuclei. By splitting are released from the nucleus of neutrons that collide with other nuclei causing them to split and subsequent emission of neutrons. This is called a chain reaction. The condition calls self-sustaining nuclear reaction is slowing down neutrons. For this purpose, a special substance, called moderator. The neutrons collide with the molecules of the moderator precipitate heating speed while the moderator. The resulting heat heats the water so that a couple who drives a turbine generating electricity. Another way of producing nuclear energy is nuclear fusion, in which nuclei combine to light elements. So far, fusion, however, failed to carry out so that it can be applied to the economy as a source of energy.
