d. populations have more weak members than strong

6. In most cases bio luminescence is useful for ?
a. attracting prey
b.producing oxygen
c.supporting plant life
d.navigating dark waters

Answer 1

5. The creatures that are poorly suited to the environment do not generally weaken the entire population because they often die before they can reproduce

6. Bio luminescence is useful for attracting prey, navigating dark waters.

Step-by-step explanation:

5.In theory of evolution it is said that individuals that are poorly adapted to the environment, have lesser chances of survival and reproduction. It is also assumed that their genes are unlikely to be transferred to the coming generation and hence they are not going to affect the entire population.

6. The bio luminescence is the process occurring in marine animals producing light energy. Luciferin is a chemical found in them when exposed to oxygen emits light.

Deep in the sea the sunlight does not peneterate so light obtained from bioluminescence is the option for navigating dark waters.

In Bio luminnescence the light emitted will weaken in presence of bacteria and toxins eventually falling prey.
