A male rabbit with genotype GgBb x with a female rabbit with genotype ggbb. Set up the Punnett square and determine the expected

marysya [2.9K]

Answer:

<h2>25% all with genotype; GgBb, Ggbb, ggBb, ggbb.</h2>

Explanation:

1. Male rabbit genotype = GgBb;

so,gametes are; GB, Gb, gB, gb

female rabbit= ggbb

so, gametes are; gb all.

2. Cross between these rabbits = GgBb× ggbb

Punnett square;

GB Gb gB gb

cross with gb

3. So, progeny are GgBb, Ggbb, ggBb, ggbb

So, all genotypes are 25%.

What ion movement changes the membrane potential in a contractile cell from negative to positive during the rapid depolarization

Lesechka [4]

Answer:

The influx of calcium ions.

Explanation:

The influx of calcium ions at a certain point produces phase of the action potential also called depolarization which results in the ion movement changes the membrane potential from negative to positive inside the cell.

In action potential, calcium ions may control gene transcription, cell excitability, and neurotransmitter release. In chemical synapses, the influx of calcium ions leads to vesicles filled with neurotransmitters move to the surface of the cell, and into the synaptic cleft release their contents.

What are the skeletal difference between a biped and a quadruped?

Allushta [10]

To see the difference between <span>biped and a quadruped,</span> let's compare the skeletons of the man (biped) and the horse (quadruped):

*The man has the bigger pelvis: he has to bear the weight of the body.*The scapula is smaller.*The bones of the hind leg bigger.*The forearms more mobile.*The man has the spine that attaches under the skull.*And the tail that has completely regressed.
the man has adapted to standing and biped (he walks on 2 feet): his hind legs are reinforced.
