Homeostasis is maintained through feedback mechanisms.

a. True
b. False

a. True

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.

During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.

For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
