Answer: A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England.

Explanation:

Natural selection is a process of differential survival and reproduction. It suggests that the organisms which have better traits are likely to survive in changing or adverse environmental conditions.  

Among the options given, A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England. is the correct option. This is because of the fact that the during industrial revolution the emission of soot from the factories will mask the original light color of the tree bark. The dark colored peppered moths when lying on the bark of the tree will get an advantage of survival due to the similarity in the background. Hence, this will help the peppered moths in camouflaging and remaining undetected from the predators. Hence, it can be said that the dark color is the phenotypic trait which helps in survival of the dark colored peppered moths. Therefore, it is the example of natural selection.

ozzi

Answer:

poliinators and flagellated sperm

Explanation:

Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales  belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.

Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.

Also, unlike other groups of gymnosperms, cycads have specialized  pollinators, beetls.

nasty-shy [4]

Answer:

Principles by Mendel

Explanation:

The heritage principles of Gregor Mendel are at the core of modern genetic engineering. Mendel has created three heritage principles by conducting experiments with pea plant breeding, which described the passing on of genetic characteristics before anyone thought that genes did exist.Mendel referred to this components as "elementen" and suggested that, throughout sexual reproduction, each parent contributes a form of elementary elementen to the resultant offspring. This blend of parental elementen then defined what type of characteristic was noticeable in the descendants.

Genetic concepts are laws or guidelines regulating the biological heredity process, the transition of parents' to children's attributes by information that is biochemically transmitted by DNA, to gene units.
