Match the description of an object's motion with the position-time graph that represents at A. slowing down
B. moving with constant speed
C. not moving
D. speeding up

1) D

2) C

3) B

Explanation:

1) The position and time increase, speeding up

2) The position and time do not change, therefore it is not moving

3) The position and time are moving, but at a constant speed.

Explanation:

1.)The top on is moving at a constant speed

2.) is not moving.

3 is slowing down

4.) The last one is speeding up

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

what's the question ?
