A solution that is:

Isotonic to the cell would cause no visual changes as the rate of water entering the cell is equal to the water exiting the cell.

Hypotonic to the cell would cause the cell to shrink, as water exits the cell to dilute the higher solute concentration outside the cell.

Hypotonic to the cell would cause the cell to swell, as water enters the cell to dilute the higher solute concentration inside the cell.

Hitchhicker's thumb is a condition in which a person is able to bend his thumb backwards. This trait can be seen in many people but the condition is recessive, which means a person needs two alleles for hitchhiker's thumb to have this particular characteristics. The gene for straight thumb is commonly indicated by T while that for hitch hicker's thumb is indicated by t.

Let's see what will happen if a person heterozygous for hitchhiker's thumb marries a woman who is also heterozygous for hitchhiker's thumb.

P1: Tt X Tt

Gametes: t T : t T

Offsping : TT : Tt : tT : tt

TT : 25 % : Straight thumb

Tt + tT : 50% : Straight thumb

tt : 25% : Hitch hicker's thumb

Therefore, there are 25 % chances that their offspring will have Hitch hicker's thumb and 75 % chances that they will have straight thumb.

Hope it help!

Through sexual contact or blood contact, the human immunodeficiency virus, which causes HIV infection, can be contracted. Many people are infected by sharing needles and having unprotected sex-ual contact with HIV/AIDS sufferers.

<h3>Describe HIV?</h3>

The human immunodeficiency virus, or HIV, preys on the body's immune system. HIV can progress to AIDS if it is not treated (acquired immunodeficiency syndrome).

There is currently no effective treatment available. When someone contracts HIV, they are always contaminated. However, with the correct medical attention, HIV can be controlled. People with HIV can live long, healthy lives and maintain their relationships if they receive effective HIV treatment.

The development of new medications can aid in reducing the effects of HIV/AIDS on people. It cannot be passed to offspring because some firms are already involved and using new treatments.
