Internal gestation followed by live birth is an evolutionary development most likely driven by which of the following? a. the inability of eggs to acquire nutrients to grow complex animals b. the need to give birth and reproduce on dry land where eggs could dry out c. the threat of predators to eat eggs d. environmental conditions caused eggs to over-absorb dangerous molecules from the environment

Internal gestation followed by live birth is an evolutionary development most likely because the of the threat of the predators to eat the eggs.

Option C

Explanation:

Reproduction is the activity followed by all organisms in order to maintain their species in this mother earth , as the evolution came by the organisms started to keep their young little ones in an egg inside themselves in order to protect these eggs form the predators that attack the parent and consume the young ones.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

thinking it would be d not too sure but i think it's right
