Proteins encoded by genes within the same gene family are often said to have modularity if structure because: a) they are affected by the same transposons
b) gene duplication always shifts protein module around
c) gene families arise from gene fusion, which creates two distinct modules
d) gene families usually have similar DNA sequences and therefore similar protein structure

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

what is shown in the image?
