Answer:
The correct answer is - option B. They are small because they lack a nucleus.
Explanation:
Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.
In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.
Thus, the correct answer is : option B. They are small because they lack a nucleus.
Answer:
the answer is F oxygenated blood circulates back into the heart and is then pumped to all parts of the body through the arteries
Answer:
A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells. Ribosomes are specialised cell organelles and found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins
Explanation:
Answer:
Proteins
Explanation:
They are found everywhere in the body from muscle, cell membranes, hair, enzymes, and etcetera and are responsible for the phenotype of organisms. Proteins are the ultimate expression of genes in the DNA of organisms. The DNA is transcribed by DNA polymerase into mRNA, then mRNA is translated into protein by ribosomes. This general rule is called the central dogma.
