how is genetic variation generated within the ciliate paramecium

The correct answer is D.

D.) a trait is advantageous and is passed through generations

There are different kind of adaptations occur in the life of organisms. Adaptations actually help organism to blend with their environment and are necessary for the survival of an organism. When organisms found a trait useful for them, they adopt it and with the passage of time they inherit that trait to their off springs.

The correct answer is B.

B.) there is competition within a species for resources, and only the single most fit individual will survive

Intraspecies competition means the competition within the individual of same species and only the fittest of all the individual will survive. This is the phenomenon of natural selection, in which nature select only most  fit individual for the next generations.

The correct answer is C.

C.) Fish C because of its streamlined shape and lack of pectoral fins.

Epipelagic zone is the zone of the sea where most of the sunlight penetrate. It is also called sunlight zone. Fish C is best adopted here because of its streamline shape and lack of pectoral fins.

The correct answer is B.

B.)An eye color different from one's parent

The inherited traits are the traits of individuals that are inherited from parents through genes. So, if an individual exhibit different eye color from his parents. It meas that he is showing inherited variation.

The correct answer is "A" according to graphic organizer.

Genetics always include both natural and artificial factor so that they can examine both the natural and artificial factor in inheritance or heritable variation.

The correct answer is C.

C.) Genetic traits that help fish survive are more likely to be seen in future generations.

The environmental factor such a over fishing affect genetic factors such as that only that genetic traits that help fish survive are more likely to be seen in future generations.

The correct answer is B.

b.) the survival of the fittest due to competition of resources.

In the over production of a population, the survival of the fittest due to competition of resources is a benefit. Because in this way only some of the fittest individual will survive and it will reduce the over production.

Eukaryotic genetic variation occurs with vertical gene transfer while prokaryotic genetic variation occurs with horizontal gene transfer.

Explanation:

Genetic variation is when the genetic content of the offsprings are different from that of the parents. It is a phenomenon achieved in different ways by different organisms. Eukaryotic organisms undergo sexual and asexual reproduction in which they transfer genetic material (DNA) to their offsprings. This process of transfer of DNA from parents to their offsprings is called VERTICAL GENE TRANSFER. In sexually reproducing organisms, meiosis is undergone where CROSSING-OVER is the process that increases the chances of genetic diversity.

However, in prokaryotic cells that use other methods like transformation, transduction and conjugation to increase genetic diversity among their species since asexual reproduction does not produce genetically different offsprings. Prokaryotes like bacteria transfer or receive genetic material (DNA) from other bacteria species that are not their offsprings. This process is called HORIZONTAL GENE TRANSFER.

A

Explanation:

All living organisms pass on or transfer their genetic material to their offsprings. However, this transfer of genes occurs through the process of reproduction (sexual or asexual). Reproduction may (in case of sexual) or may not (in case of asexual) ensure genetic variation among species.

Eukaryotes that undergo sexual reproduction increase genetic variation among their species by undergoing Crossing-over (exchange of chromosomal segment between non-sister chromatids of homologous chromosomes) during meiosis or gamete formation. This process of transferring genetic material directly from parents to offsprings is called VERTICAL GENE TRANSFER, and only sexual-reproducing eukaryotes ensure genetic variation through this process.

On the other hand, prokaryotic organisms cannot undergo sexual reproduction, they undergo asexual reproduction instead and asexual reproduction does not guarantee genetic variation since identical daughter cells as the parents are produced from the process. However, to promote genetic variation among their species, they employ the processes of transformation, transduction and conjugation which are all forms of HORIZONTAL GENE TRANSFER because it involves transfer of genetic material from one cell (donor) to another (recipient) which do not have the parent-offspring relationship.

B

Explanation:

B

Explanation:

The answer would be D)asexual reproduction.

Asexual reproduction will produce a offspring that has the same genetic material with their parent. That mean the offspring will have the same genetic that code their parent color, thus their color is the same as their parent. Other option will allow the offspring to have different genes, so the offspring could have different color.

A. Individual organisms are able to change their genetic adaptations in

order to better survive in changing environments.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

The statements which are consistent with the concept of natural selection includes;

I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.

II. There is genetic variation within populations. This simply means that tere is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.
