Answer:

b) Gonadocorticoids are secreted by zona reticularis.

Explanation:

The adrenal gland is made up of adrenal medulla (inner part) and adrenal cortex (outer part). Adrenal cortex is subdivided into Zona glomerulosa, Zona fasciluta, zona reticularis.

a) Zona glomerulosa is main site for production of mineral corticoid.

b) Zona reticularis secretes gonadocorticoid.

c) Epinephrine and norepinephrene are secreted by adrenal medulla

d) Zona fasciluta is the site for the production of glucocorticoid.

Of the three primary germ layers, which is responsible for developing into nervous tissue?

nadezda [96]

Answer:

D. All three primary germ layers develop into some more type of nervous tissue

Explanation: All of the primary germ layers have specific nervous tissue development. a) Ectoderm - neuroectoderm (neural tube, neural crest). b) Endoderm develops into (among others): The digestive tract and its attached glands; the inner lining of some organs, such as the lungs, nervous tissue; epidermis . c) Mesoderm - notochord signals the ectoderm to develop the neural crest more

C) What does this cladogram tell you about the evolutionary relationship of the traits of jaws

schepotkina [342]

Answer:

In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.

<em>The cladogram in the above picture shows that the limbs originated after the jaws. </em>

The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.

You transform an E. coli bacterium with the pGLO plasmid. After growing the +pGLO bacteria on an LB+Ampicillin+Arabinose plate,

musickatia [10]

Options for the question have not been provided. The complete question has been attached.

Answer:

A. Yes, we will see growth. Yes, they will glow.

Explanation:

pGLO plasmid was engineered to be used as a vector in the field of biotechnology. It has an ampicillin resistance gene which acts as a reporter gene. It also has another reporter gene, GFP which shares its promoter (araC) with the gene responsible for metabolizing arabinose. GFP gene is thus translated only in the presence of arabinose in the medium since the promoter is active only in the presence of arabinose. Once the GFP gene is translated, the colonies glow with green fluorescence under UV light.

Here, the <em>E.Coli</em> colonies were grown successfully on LB + Ampicillin + Arabinose plate so they were ampicillin resistant. They also glowed in UV light. If these transformed colonies are inoculated in another LB + Ampicillin + Arabinose plate they will be able to grow successfully since they are ampicillin resistant. They will also glow because the new plate also has arabinose so the araC promoter will be active and expression of both GFP gene and arabinose metabolizing gene will occur.
