Answer:
B. Resources such as time and energy are limited, so survivorship and fecundity cannot both be maximized simultaneously.
Explanation:
Each species trade-off between the survival and the life history traits such as a number of offspring produced, parental care and frequency of reproduction. Both reproductive success (fecundity) and survival success cannot be maximized due to limited resources.
For instance, species such as mosquitoes spend minimum energy is parental care but produce a large number of relatively unprotected young ones when the growth conditions become favorable to ensure the continuity of the species. They cannot spend much time in acquiring reproductive maturity and post natal care due to a small period of favorable growth conditions. On the other hand, most of the mammals such as human beings spend their energy in pre- and postnatal care to their young ones.

Answer:
The correct answer or fill in would be- but <u>Change and evolve</u> over time.
Explanation:
The perfect cosmological principle is a extended version of the cosmological principle. The perfect cosmological principle says that the universe is look same from all directions but can be change and evolve with time.
Steady state theory supports this theory as it also says that universe is expanding but also maintain its density even though it continuously creates stars and galaxies but still look same.
Thus, the correct answer is - but <u>Change and evolve</u> over time.
