Answer:
An atom consists of protons, electrons, and neutrons.
Explanation:
The atom of an element is its smallest indivisible particle that retains its chemical properties. Atom is the fundamental and basic unit of matter.
The structure of an atom is made up of a positively charged PROTON, a neutrally charged NEUTRON (both contained in the nucleus) and a negatively charged ELECTRON that surrounds the nucleus. These three particles are called sub-atomic particles. The arrangement and number of these sub-atomic particles determine the properties of the atom.
The answer is <span>the ability to judge the location of tree branch.
Evolutionary tree represents a relationship between different group of organisms. Tree branches represent decedent groups while nodes are common ancestors of those decedent groups. This fossil skull could represent a new tree branch, so the paleontologist could judge its location.

Answer:
The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.
Explanation:
Answer:
My answer (that the information we have about codon structure is limited to the observations we can make now) is similar to the first part of your answer: that the number of amino acids that can be encoded is a function of codon length, in that both imply the (circular) argument that we must need more than 14 amino acids (plus a start and a stop, making 16) because we observe three nucleotide codons rather than two nucleotide codons. It would be nice to have a noncircular argumentf for why the minimum number of distinct amino acids is more than 14, but that is beyond my ability to construct
