1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.

GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.

Energy Generation in Aerobic and Anaerobic Conditions

Ira Lisetskai [31]

I wanted to be with you alone

And talk about the weather

But traditions I can trace against the child in your face

Won't escape my attention

You keep your distance via the system of touch

And gentle persuasion

I'm lost in admiration, could I need you this much?

Oh, you're wasting my time

You're just, just, just wasting time

Something happens and I'm head over heels

I never find out until I'm head over heels

Something happens and I'm head over heels

Ah, don't take my heart, don't break my heart

Don't, don't, don't throw it away

Two bacterial strains have the same genes for metabolizing carbohydrates, but one is wild-type for a regulatory inducer while th

klemol [59]

Answer:

b. The two bacterial strains have different phenotypes.

Explanation:

In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.

Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.

Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
