Answer:

<h2> (1/4 * 60) </h2><h2>The probability. that child will have extra fingers and toes are = 0.15 </h2>

Explanation:

As given; extra fingers and toes are caused by a recessive trait.

Penetrance= 60%.

Parents are heterozygous, assume  Ff and Ff

F is dominant over f, and ff are homozygous recessive.

Ff crossed with Ff

Progeny are; FF, Ff, Ff and ff.

ff are homozygous recessive, as given that extra fingers and toes are caused by a recessive trait, so 1/4 will show the trait.

But according to 60% penetrance the trait will occur in = (1/4 * 60) =15% or 0.15 progeny will show the trait .

The probability, that child will have extra fingers and toes are = 0.15

Proteins produced by the immune system to destroy substances containing antigens are called
Tomtit [17]
Antibodies, also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it.<span>

Question in link below.
bezimeni [28]

The correct answer is - They supply the energy needed for living processes.

Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.
