Answer:
C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
Explanation:
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, usually protein. Gene expression include steps such as
• transcription – part of DNA is copied into mRNA via an enzyme RNA polymerase
• RNA splicing – formed mRNA during transcription is not mature so it need to be proceed (e.g. excision of introns). Mature mRNA are then exported from nucleus to cytoplasm
• Translation – mRNA serves as information that codes for the synthesis of one or more proteins.
Answer:
The foramen magnum was not located at the bottom of the skull
Explanation:
The foramen magnum is a large hole or opening found in the base of the skull through which the spinal cord passes.
The position of the foramen magnum is important since it allows the skull to balance on the body hence essential for posture.
Humans are bipedal and Howler monkeys are quadrupedal hence the positioning of the foreman will be different.
That is how the skull found was realized it was not human
<span>Glucose which can also be fats from excess carbohydrates.
Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.<span>

Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
