Answer:
B
Explanation:
This involves selectively breeding two or more populations of a species or subspecies with desirable traits that are wanted by the humans. The offspring of the populations will bear the desired traits from the population. Breeding can be done over generations. An example is the breeding a cattle population that is resistant to drought and another that produces more milk. The filial generations will bear both traits.
Answer:
D) a group of feathered, endothermic dinosaurs
Explanation:
Birds are a group of endothermic dinosaurs, characterized by feathers, epidermal structures that form plumage. Warm-blooded animal species (endothermic) maintain the body temperature higher than their environment.
Answer A is false because although birds are feathered and lack teeth, they are NOT ectothermic lizards.
Answer B is false because although birds lay amniotiv eggs, birds are a different taxonomic group than mammals, and not all birds fly.
Answer C is false because although some reptiles are closely related to birds, the current scientific consensus is that birds are a group of dinosaurs. Also, not all birds fly, and although they have lost the teeth, they have NOT lost the amniotic egg.
Answer:
very STR has multiple alleles, or variants, each defined by the number of repeat units present or by the length of the sequence. ... Flanking regions are important because knowing their sequences enables geneticists to isolate the STR using polymerase chain reaction, or PCR, amplification.
Explanation:
<span>Carbon is present in the biosphere and other systems of the planet and is an essential part of life. Carbon moves through these systems by feeding the heterotrophs of other organisms, through the consumption of dead organisms. When oxygen is present, there is aerobic respiration, which releases carbon dioxide into the surrounding air or water. It plays an important role in the structure, biochemistry, and nutrition of all living cells.</span>
