The branch of biology that deals with the form of living organisms, and with relationships between their structures.
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.
The answer is B, each gamete contains the same number of chromosomes as the mother. This is through cell division when the parent cells go through two rounds of meiosis 1 and meiosis 2, and all haploid gametes have 23 chromosomes.
In the immune response the body reacts to each kind of
pathogen with a defense targeted specifically for that pathogen.
D. Derived Trait
You take an ancestor and you "extract" a trait and you put that trait into the next ancestor meaning you "derive" the trait.
