49; Number of Electrons = Number of Protons = Atomic Number
Answer:
4
Explanation:
because of the displacement
Answer:
internal receptor binding
Explanation:
This is because steroid hormones are lipids by nature (usually composed of cholesterol) so they are hydrophobic. This means that steroid hormones can easy pass through the membrane and bind to their internal receptors.
Internal receptors also known as intracellular receptors have DNA binding domain and when hormones bind to them DNA-binding site becomes exposed. Hormone-receptor complex gets into the nucleus and binds to regulatory regions of the DNA. Cellular response is gene expression.

One of the concerns regarding genetic selection is that some traits for pest resistance may affect the texture of lettuce, it is known as pleiotropic effects.
<h3>What is a pleiotropic effect?</h3>
In genetics, a pleiotropic effect occurs when one gene influences the phenotypic expression of several traits.
Pleitropic effects represent a problem in breeding programs because positive selection for a trait can also produce negative selection for another trait.
In conclusion, one of the concerns regarding genetic selection is the presence of pleiotropic effects.
