Answer: E.coli bacteria reproduce in liquid media containing either glucose or galactose

Explanation:

Answer:

Option B

Explanation:

E.coli has a preference of glucose over other energy molecules and therefore whenever glucose it present, it leaves no chance of metabolizing and using it as a source of energy.  

However, in absence of glucose E.coli uses alternative energy sources such as galactose, maltose, lactose, arabinose etc. Therefore, it is clear that in order to sustain, an organism or bacteria follows multiple metabolic pathways to derive energy from various energy sources.

Hence, option B is correct.

Individuals producing an abnormal form of the extracellular matrix protein, fibrillin, is a result of ______.
erastova [34]

Answer:

Indivisuals with producing an abnormal form of extracellular protein fibrillin are suffering from Marfan syndrome ehich is caused by genetic mutation in the FBN1 gene.

Explanation:

Gene mutations in FBN1 gene results in the production of an abnormal extracellular matrix fibrillin-1 protein that cannot function properly. These gene mutations basically reduce the amount of fibrillin-1 produced by the cell, alter the structure of fibrillin-1, or causes the impairment of the transport of fibrillin-1 out of the cell.

As a result, protein is poorly incorporated into extracellular matrix. Hence, indivisuals with Marfan syndrome present following symptoms

Tall stature.

Disproportionately long arms, legs and fingers.

Sternum either protrudes outward or dips inward.

Arched palate and crowded teeth.

Heart murmurs.

Extreme nearsightedness.

marysya [2.9K]
After looking at the graph represented above, I think I habe recognized the correct answer, <span> so the statement  which would best predict the population in generation 4 is being shown in the first option : </span><span>The nonresistant aphid would become extinct. As you can see from the tree pictures, nonresistant ones gradually become lower and lower and in the last one it has the same weak position as resistant in the first picture, then I would say that nonresistant will expire soon.

Hope that helps!</span>
