It is estimated that only one in a thousand sea turtles make it from eggs to adults. what is this an example of?
select one:
a.

overproduction
b.

variation
c.

survival of fit individuals
d.

none of the above

The correct answer is-

A) Overproduction.

A sea turtle has the potential to lay upto 110 eggs but most of them die and only 1 in 1000 survive so as to produce a fertile offspring ( that is eggs to adult).

Overproduction is an essential phenomenon in evolution as the best suited/ adapted organisms survive to adult stage so as to reproduce fertile offspring.

In overproduction, large number of offspring or eggs are produced but only few survive.

In this case, a larger number of eggs are produced but only few are surviving and reaching adulthood.

Thus, it is an example of overproduction.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
