Which are examples of negative feedback? Select three options. a child whose thymus gland is building an immune system that gets stronger each day when someone's adrenal gland reacts to a scary movie by secreting hormones that make the heart beat quickly when someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently when someone's pancreas hormone increases every time they eat, but decreases when they aren't eating when a person takes calcium supplements so a gland will stop secreting a hormone that pulls calcium from the bones

The last three options

Explanation:

In the first two options, there's positive feedback, the change that the body produces (development of thymus or secretion of adrenaline) keep increasing with the stimulation (growth of the child with immunologic stimulation and fear when watching the movie, respectively).

In the last three however, the increase in a stimulation (hunger, feeding, calcium levels in plasma), causes a decrease in the body's functions (less of the hormone that lowers blood glucose levels, less of the hormone that raises blood glucose levels and less of the hormone that pulls calcium out of the blood, respectively).

last 3

Explanation:

took the test

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents

explanation:

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
