Astudent claimed that a solution with a concentration of na+ of 5.0 ppm will have a lower measured absorbance than a solution with a 1.0 ppm concentration of na+. based on the results of experiment 1, explain why the student’s claim was incorrect. as part of your explanation, give your prediction for an approximate measured absorbance for a solution with a 5.0 ppm concentration of na+.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
