Explanation:
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.
Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine.

Answer:
The correct option is Blood cells are produced in bone marrow.
Explanation:
Skeletal system can be described as the system which comprises of all the bones and joints of an organism. The main function of the skeleton system is to provide support and protection to the organism.
The circulatory system can be described as a system which comprises of the heart, blood vessels and blood. This system is mainly involved in the transportation of substances like oxygen, nutrients etc in the body.
The skeletal system interacts with many other systems of the body and helps them perform their functions. For example, the skeletal system interacts with the muscular system so that a muscle can contract and relax.
The skeletal system interacts with the circulatory system by producing blood cells in the bone marrow. Red blood cells, as well as white blood cells, are produced by this process.
Answer:
the basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions.
Explanation:
Answer:
Menisci are the semi-lunar fibrous cartilage of the knee which could be either medial meniscus or radial meniscus. The meniscus in humans is present in the joints of the knee, sternoclavicular joints, wrist and temporomandibular joints.
These menisci play important roles in these joints as they reduce the friction caused by the bones during movement. They also disperse the weight of the body of the humans as they spread the load of the weight of the body to different bones like the femur and tibia.
An amino acid can be formed by combining 3 nucleobases. In the test, the only nucleobase the mRNA is uracil. That means the possible combination of the nucleobase should be only UUU. Since there is only 1 possible combination, there should be 1 possible amino acid that can be formed.
<span>Phenylalanine should have UUU codon.</span>
