When cells want to store up energy will they add or delete a phosphate group

they will add.

Explanation:

When a cell has energy available it can store small amounts of energy by adding a phosphate group to ADP molecules producing ATP molecules. The energy stored in ATP is released when ATP is converted to ADP and a phosphate group.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

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
