Multicellularity, homeostasis, structure and function

Question 1

the 4 types of tissue

Answer 1

connective, epithelial, muscle, nervous

Question 2

connective tissue

Answer 2

connects things, ex: fat, bone, cartilage

Question 3

epithelial tissue

Answer 3

covers our body surfaces

Question 4

muscle tissue

Answer 4

skeletal, smooth, cardiac

Question 5

nervous tissue

Answer 5

specialized cells that conduct signals

Question 6

what happens to the SA to volume ratio as animals get larger?

Answer 6

the ratio gets smaller

Question 7

When is diffusion limiting (with SA vs V)

Answer 7

when the ratio is small (rate is the same but there are larger distances which makes diffusion less effective)

Question 8

bulk transport

Answer 8

transporting materials through the different systems rather than diffusion (over longer distances)

Question 9

homeostasis

Answer 9

process by which the body maintains a stable uniform internal state

Question 10

what does homeostasis use?

Answer 10

negative feedback

Question 11

negative feedback

Answer 11

stimulus –> sensor –> effector –> response repeats
