Can you accurately determine an genotype by observing its phenotype?

1 answer:

6 0

Yes. We can determine an genotype by observing it's phenotype by a "Test Cross".

If we cross between Homozygous recessive plant with dominant one, we can tell from the results of cross, that dominant individual is Homozygous or Heterozygous,.

Hope this helps!

A red blood cell with an osmolarity of 300 mOsM (non-penetrating solutes) swells but does not lyse when placed in a 300 mOsM sol

Mashcka [7]

Answer:

See below for answer

Explanation:

A. 200 mOsM NaCl

This solution is hypotonic to the red blood cell (RBC) with penetrating solute. The RBCs will swell up and burst because the water will move into the cells.

B. 400 mOsM urea

This solution is hypertonic to the RBCs with non-penetrating solutes. Water will leave the cells via osmosis and the cells will shrink and appear shriveled.

C. 100 mOsM urea plus 200 mOsM NaCl

This time both penetrating and non-penetrating solute is present. The solution is isotonic to the RBCs and although there will be movement of water between the cells and the solution, there will be no overall change in the concentration of water for each and no change in appearance of the cells.

D. 300 mOsM urea

The RBCs will not lyse nor shrivel as again the solution is isotonic to the RBCs.

siniylev [52]

Answer:

Spinous process

Explanation:

The rhomboideus minor muscle originates on the spinous processes of vertebrae T2-T5

The rhomboideus minor muscle forms part of the superficial group of back muscles. The muscles in the superficial group are immediately deep to the skin and superficial fascia. They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).

These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.

The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.

bogdanovich [222]

BROCA'S AREA Broca's area or the Broca area is a region in the left frontal lobe of the dominant hemisphere of the hominid brain with functions linked to speech production. Broca area, also called convolution of Broca, region of the brain that contains neurons involved in speech function. This was discovered in 1861 by French surgeon Paul Broca, who found that it serves a vital role in the generation of articulate speech.
