Explanation:
Answer:
D. Because science only uses facts that are proven 100% true through the use of variables.
Explanation:
All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is proven 100% true through the use of variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.
Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of variables.

Answer:Transcription.
Nucleus is the site of these converti
Explanation:
The DNA of a specific gene is the template f or the complementary base-pairing,
RNA polymerase enzyme is the name of the enzyme that catalyzes thr conversion of the pre- mDNA to fully mature mRNA..
This process involves splicing t;hat is the removal of precise introns from the primary RNA transcripts.
It is controlled by complexes of protein and spliceosomes.
Answer: The tuatara is a lizard-like reptile found only in New Zealand today, the last surviving lineage of a large group of reptiles that were contemporaries of the dinosaurs.
The traits that would i expect the <u>tuatara</u> to possess are:
- Spiny back similar to that of dinosaurs.
- A well developed pineal eye.
- It lacks a copulatory organ.
- Spine-like vertebrae with intercenters.
- Anterior teeth, large and very sharp.
Explanation:
<u>Living fossil</u> is an expression used to qualify non-extinct species that are extremely similar to species identified only through fossils.
A <em>pineal eye</em> is a part of the epithalamus present in some animal species. The eye can be a photoreceptor and is commonly associated with the pineal gland, regulating the circadian rhythm and hormonal production for thermoregulation. The tuatara has a developed parietal eye, <u>with retina and lens.</u>
