Answer:
Explanation: Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes. ... The vast majority of protists are unicellular or form colonies consisting of one or a couple of distinct kinds of cells, according to Simpson.
Natural selection is the idea that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring.
<h3>What is natural selection?</h3>
The question is incomplete but I will try my best to explain the idea of natural selection.
The term natural selection refers to the idea put forward by Charles Darwin that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring. This is also called the survival of the fittest.

Answer:
Tell the younger student that organs are singular objects and systems are a group of organs that work together to perform certain jobs.
Explanation:
Organs are singular units that play a part of human survival. (Ex. the heart cleans the blood and pushes through your veins)
Systems are a group of the singular units that work together to perform a certain function.
(Ex. Lungs, heart, veins and arteries make up the circulatory system which transports oxygen, blood, and nutrients through out your body)
Well it’s obvious that they both use Photosynthesis to make there own food, and also they both use chemosynthesis the produce there own food. Very simple. :)
I got you :)
The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.
