When planning space exploration, scientists face many challenges. One issue is the weight of the items being transported. They can use the engineering design process to help minimize the weight of materials on board a spacecraft The engineering design process starts with a statement of the problem to be solved. Which sentence best states the problem described above? A. Space vessels must carry heavy equipment but also minimize weight O B. Lower gravity on the Moon means that objects weigh less on the Moon than on Earth. O C. The longer a space flight will last, the more equipment must be carried D. Metal is stronger than plastic, but it is also much heavier,

Just took the quiz and the answer was A! don't give me credit, give the person above all the credit ^^

very easy

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.
