C. this individual is a male since he has X and Y chromosomes
A monomer can be defined as the molecule that is capable of binding in long chains. The monomers bind together to form different polymers by the process of polymerization.
The monomer of carbohydrate is monosacchride. The monomer of proteins is amino acid, and that of lipids is glycerol and fatty acids. These three macromolecules are wrongly paired in the question.
The monomer of nucleic acids is nucleotide. This is correctly matched.
Hence, the correct answer is 'Option B - nucleic acids - nucleotides'.
Answer: SKELETAL MUSCLE
Explanation:
Skeletal muscles is a type of muscle tissue that forms those muscles that move the bones of the skeleton,straited because straitations (strips) can be seen on microscopic examination and involuntary as it is under conscious control.
Although most skeletal muscles move bones,they also accomodate a degree of voluntary control in breathing.
A lot of movements can be finely coordinated.example; writing but may also be controlled subconsciously, maintaining an upright position does not normally require thoughts unless a new locomotor skill is being learned example skating or cycling and the diaphram maintains breathing while asleep.
The fibre (cells) of the skeletal muscle are cylindrical,contain several nuclei and can be up to 35cm long.
Skeletal muscle contraction is stimulated by motor nerve impulses originating in the brain or spinal cord and ending in the neuromuscular junction.
The contraction of a whole skeletal muscle occurs because of coordinated contraction of it's individual fibres.
