All the options are correct.

1. New ways to preserve and transport blood for blood transfusions were discovered.

2. Blood transfusion safety was improved.

3. Scientists discovered that elements of blood could be separated by centrifuge.

4. Scientists discovered that plasma could be preserved by freezing.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

<em>Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.</em>

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

<span>Connective tissue supports the framework of the liver, and epithelial tissue protects the liver. Connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver. Connective tissues are mainly used in forming support networks within tissues and Epithelial tissue tend to line the organs and form protective cell layers.</span>

If speciation occurred solely because of changes in chromosome counts between the original parents (who were 2n) and the offspri

Ket [755]

Answer:

Yes...This is an example of speciation by natural selection

Explanation:

As we know that natural selection always promote those evolutionary changes that are necessary. Changes that happen in chromosome number always promote with a specie that is closely related to the parent specie and produce fertile off-springs. These new generations are most adaptable and can survive in the environment more efficiently than the previous ones.

Additionally, other than natural selection, speciation can also happen as a result of random mutations, genetic drift and by means of artificial selection as well. But the natural likelihood of all these is probably low as compared to that of natural selection.
