How is habitat fragmentation related to biodiversity loss? less carbon dioxide is absorbed by plants in fragmented habitats. in fragmented habitats, more soil erosion takes place. populations of organisms in fragments are smaller and, thus, more susceptible to extinction. animals are forced out of smaller habitat fragments. fragments generate silt that negatively affects sensitive river and stream organisms.

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

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
