nasty-shy [4]

Answer:

(D) mutant

Explanation:

Translation occurs at the ribosome, which consists of rRNA and proteins. ... Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein.  A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.

PtichkaEL [24]

Answer:

1. Muscle Fibers

2. Bones

3. Joints

Explanation:

Muscle tissue is made of muscle fibers. The plasma membrane of a muscle fiber is called sarcolemma while its cytoplasm is known as sarcoplasm. Muscle cells are characterized by the presence of specialized endoplasmic reticulum which is called sarcoplasmic reticulum.

Muscle cells exhibit contractility and extensibility. The ability of muscle cells to shorten their length forcibly in response to a stimulus is their contractility. Muscle fibers have the ability to extend and shorten themselves.

Extension and contraction of muscle fibers are responsible for the movement of the human body and its parts.

Muscles are attached to bones via tendons which in turn are the fibrous connective tissues. Muscles are also part of our joints where they assist in the movement by pulling the bones as well as stabilize and strengthen the joints.
