1-5 questions

Help plss

Question 1:
C. Nervous

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate B because we aren’t using the integumentary system (skin, hair).
— We can eliminate D because the respiratory doesn’t instruct any systems, it just keeps them going.

Question 2:
D. Immune, Integumentary, Circulatory

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate C because we aren’t using the muscular system (muscles).
— We can eliminate B because we aren’t using the skeletal system (bones).

Question 3:
D. None of these

BECAUSE
— We can eliminate A and C because we need the integumentary system to maintain body temperature (the integumentary system uses skin to regulate body temperature).
— We can eliminate B because we need the muscular system to maintain body temperature (the muscular system uses its ability to contract muscles to create heat).

Question 4:
B. Digestive, Circulatory, Excretory

BECAUSE
— We can eliminate A and C because we need the excretory system to digest and maintain homeostasis (to prevent damage to the body).
— We can eliminate D because B is our answer.

Question 5:
B. Reproductive, Nervous, Endocrine, Circulatory

BECAUSE
— We can immediately eliminate A, C, and D because we need the excretory system (hormones) to reproduce.

What is the example? i’ll be happy to answer if you can tell me : )

Transpiration is the answer
