1. 0 because they are nonpolar,  more concentration of molecules because of a proceess called simple diffusion,

2.  o because it is a form of passive energy, low concentration,

3. molecules moving, equilibrium, higher, lower

These processes are all Passive and therefore none require energy although some are different the first is the molecules that can just pass through and yea, then thefacilitated diffusion is through moleules moving because of concentration differences, then Osmosis is when molecules because of water differences.

What movement of the thumb would be most affected by lesion of the median nerve in the cubital fossa
natka813 [3]

Answer:

flexion

Explanation:

The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.

In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.

The flexion occurs in the sagittal plane.

Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

Gregor Mendel crossed true-breeding plants with green pea pods with true-breeding plants with yellow pea pods. The resulting F1
Alchen [17]

Answer:

A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.

Explanation:

The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.

The F1 cross would therefore be Gg x Gg. See attached punnet square.

The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1

Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)
