Answer:

Artificial selection is  process in which humans select the traits in animals and plants and use animal breeding or plant breeding to produce the animal or plants with desired traits.

Different dog breeds is very good example of artificial selection because with the help of artificial selection humans can  drastically alter the appearance of dogs. With artificial selection human can develop Great Dane from the tiny Chihuahua.

Answer:

When humans breed animals for a specific trait.

Answer:

The only way to make a whole population evolve is through natural selection.

Answer:

B

Explanation:

The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)

Hope this helps :)

The statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

The fossils are the preserved materials of the animals and plants, such as the skeleton, teeth, bones, imprints, and other parts stored in the different layers of the earth. These fossils are preserved in natural ways, not by humans, and they are helpful for the study of the different animals because some fossils give the idea of the connecting links, and they give the idea of the animals' living conditions in the early time.

Hence, the statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

Answer:

The delivery of the paternal genome to the egg is a primary goal of fertilization. In preparation for this step, the nucleus of the developing spermatozoon undergoes extensive morphological and biochemical transformations during spermatogenesis to yield a tightly compacted sperm nucleus. These modifications are essentially reversed during fertilization. As a result, the incorporated sperm nucleus undergoes many steps in the egg cytoplasm as it develops into a male pronucleus. The sperm nucleus (1) loses its nuclear envelope, (2) undergoes nucleoprotein remodeling, (3) decondenses and increases in size, (4) becomes more spherical, (5) acquires a new nuclear envelope, and (6) becomes functionally competent to synthesize DNA and RNA. These changes are coordinate with meiotic processing of the maternal chromatin, and often result in behaviors asynchronous with the maternal chromatin. For example, in eggs fertilized during meiosis, the sperm nucleus decondenses while the maternal chromatin remains condensed. A model is presented that suggests some reasons why this puzzling behavior exists. Defects in any of the processes attending male pronuclear development often result in infertility. New assisted reproductive technologies have been developed that ensure delivery of the sperm nucleus to the egg cytoplasm so that a healthy embryo is produced. An emerging challenge is to further characterize the molecular mechanisms that control sperm nuclear transformations and link these to causes of human infertility. Further understanding of this basic process promises to revolutionize our understanding of the mystery of the beginning of new life.
