Answer:
Atoms are made of the same type of parts,but the sizes change
Explanation:
The first answer is correct. rRNA makes up ribosomes along with other protiens. rRNA stands for ribosomal ribonucleic acid
Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

Remember that a controlled variable is a variable that stays the same thoughout the experiment.
it wouldn't be a. because two different wires were used
the final length of the wax would be your dependent variable, so it wouldn't be c.
the thermal conductivity is the independent variable so it isn't d.
the original length of the wax was the same for both.
So B is your answer.
Identification of human genes and functions
Explanation:
The Human Genome Project was founded in 1990 and its primary purpose was to identify and label all human genes and their functions. Information from the HGP may eventually be used in genetic testing, the detection of mutations or variations in children, and gene therapy.
