<span>The molecular clock has been useful to determine the phylogenetic relationships of species based on the assumption that they cannot be compared to non molecular methods such as comparative anatomy. The molecular clock helps us discover organisms that have a little common traits or features between evolutionary relationships.</span>
Active Transport<span> is used when substances are to be transported against their concentration gradient ( from low concentration to high concentration ) by utilising energy from ATP.

This phenomenon is not rare in the animal kingdom. Known as alternative mating strategies, it is employed by a subgroup of males that are usually incapable of facing the larger males in direct confrontations.
These "sneaky males" as they are sometimes called, will employ alternative strategies to mate with females. Which strategy will be dominant is dependent on the environmental factors and is not permanent. In some conditions where food is not that abundant, there will be less larger males and thus, the smaller males employing this strategy will be more common. At other times the opposite will occur.
However, in most cases and most probably here, the end result will be a coexistence of this traditional and alternative mating strategy, where males will exhibit a greater diversity in phenotype.
Answer: Heredity
Explanation: organisms can reproduce only their own kind due to heredity. Heredity is the transmsion of traits and characters from a parent to its offspring through what is known as gene(a unit of heredity carried by chromosomes of cells)
Now that takes us to the second part of the question,
Traits of the parents are carried in a form of 'genetic information' and passed-on to the offspring thereby making them have a unique resemblance of their parents compared to the other individuals.
Answer: The Answer is C
Explanation:
In this way of finding information, you are physically using another object to increase your knowledge of another object.
