Answer:
This question lacks options, the options are:
a. Ribosomes
b. Centrioles
c. Mitochondria
d. Peroxisomes
The correct answer is a.
Explanation:
A ribosome is a complex macromolecular structure in the cell (a cellular organelle) that is involved in protein synthesis
. Osteoblasts are cells that produce the osteoid substance (fibers and fundamental substance). Osteoblasts synthesize the organic component of the bone matrix (type I collagen, proteoglycans, proteins involved in cell adhesion, osteocalcin and growth factors) and control the deposition of mineral salts. They have a powerful ribosomal apparatus, consistent with the intense synthesis of proteins they develop. Of these, the most important quantitatively is collagen, but they also synthesize other proteins, among which it should be noted, osteocalcin. In addition to synthesizing proteins, the osteoblast directs bone mineralization. The non-mineralized bone tissue is called «osteoid», and is formed by layers that are synthesized from depth to surface, being defined by the different orientation of the collagen fibers in each of them.
Answer:
A virus is a tiny infectious biological agent that can only replicate or duplicate inside the host cell. These infectious agents can infect all different types of living organisms ranging from animals and plants to microorganisms and archaea and bacteria.
Virions are ineffective particle or form of the virus outside of the host cell, with RNA or DNA and a protein capsid.
The main role of these infectious agent virions is to transfer the DNA or RNA genome from itself to the cell of host and expressed the gene which means produce proteins from the genome transferred to the host cell.
The answer is heterozygous.
If it was crossed with homozygous dominant, then 100% of the offspring would show the dominiant trait. If it was homozygous recessive 100% of the offspring would have the recessive trait
