Answer 1

@Abhisar

Answer 2

What do u think should be the correct option ?

Answer 3

D

Answer 4

How so ?

Answer 5

I'm stumped

Answer 6

Therapsids were more mammal like than reptiles. Their legs were straighter and closer to the body. Therapsids may have been endotherms like mammals.

Answer 7

Getting my points ?

Answer 8

@Some of the larger creature of the time were likely functionally homeothermic.

Answer 9

Endotherms are those who caan regulate their body temperature according to the changes in environmental temperature.

Answer 10

U got ur answers @Spikers ?

Answer 11

B?

Answer 12

but i think there is a difference between homeothermy and endothermy @mrdoldum

Answer 13

No its d, u were correct !

Answer 14

I think u have reversed !

Answer 15

@Abhisar Yep I do!.

Answer 16

So basically,
A better definition for Homeotherms is an organism that can maintain a internal cellular condition that is close to the metabolic optimum for the organism regardless of environment (to a point of course). This can be through behaviors. Endothermy is the active cellular maintenance, not just behaviors like sun bathing.

Answer 17

I'm deleting my reverse one so know one can get confused. I wonder, I think great white sharks are near endotherms. I'll have to check.

Answer 18

Yes sharks are endotherms, there body temperature is internally regulated by metabolism.

Answer 19

I don't think all sharks are endotherms.
