The spinal cavity ,is enclosed within the vertebral foramen of the vertebrae
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.
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.
Chloroplast is the cell structure that enables the process of photosynthesis
