A cladogram shows how species are related by descent from a common ancestor. A classification of organisms on the basis of such relationships is called a phylogenetic classification.
A phylogenetic classification involves organisms in a clade with their common ancestor.
A cladogram consists of an organism being studied, lines, and nodes where those lines cross. The lines represent evolutionary time or a series of organisms that lead to the population.
A clade is a group of living organisms and the common ancestor they are derived from.
Therefore, the cladogram is related to common ancestors through their species.

Answer:
Describe how the organisms in your cladogram are related through common ancestors. Organisms c and d share a common ancestor, a and d and b and c 5. Label : The purple lines represent a characteristic change, or adaptation . ... The “parsimony score” calculates how many changes occur in a given cladogram.
Explanation:
Oxytocin
When the critical hormone oxytocin is released in high enough concentration by the mother's pituitary gland, the mother's uterus begins periodic contraction.
Oxytocin is a peptide hormone produced by the hypothalamus and released into the blood stream by the posterior pituitary. Oxytocin works on certain organs in the body such as the breast and uterus. Oxytocin influences important functions of the reproductive system, including causing contraction of the cervix and uterus during labor, lactation, and sexual reproduction.

Answer:
A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.
Explanation:
starts when a neutron slams into an atom, causing two atoms to form one, heavier atom
starts when two atoms slam together to form one, heavier atom
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
The statement that describes nuclear fission is as follows:
Thus, the correct option for this question is D.
Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.
