Answer:

There are about 120 million rods in the human retina. The cones are not as sensitive to light as the rods. However, cones are most sensitive to one of three different colors (green, red or blue). Signals from the cones are sent to the brain which then translates these messages into the perception of color.

Translation: process of protein formation is called translation .

In the process of translation, a cell reads information from a molecule called a messenger RNA and uses this information to build a protein. Translation involves “decoding” a messenger RNA and using its information to build a polypeptide, or chain of amino acids .

Translation involve three major steps

• Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

• Elongation ("middle"): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a poly peptide chain.

•Termination ("end"): in the last stage of translation, the finished polypeptide is released to go and do its job in the cell.

Organelles involve in translation:

Ribosomes: main process of translation occour at ribosomes.

Rough endoplasmic reticulum: ribosomes are located on rough endoplasmicreticulum .it bound proteins in the vesicles.Vesicles containing proteins are budded off into cytoplasm and move toward golgi apparatus for further modification .

Golgi apparatus: synthesisezed proteins are not functional . In golgi apperatus they are further modefied and processed and stored for a short time and then released toward destination.

If blood pressure is too high what should homeostatic regulation do

Anastasy [175]

Homeostasis is one way our bodies maintain its parameters within the normal range of values. We can say that it is key to life. When homeostasis fail, it can lead to diseases like hypertension and diabetes. In homeostasis, there will be stabilization of blood pressure as well as maintenance of its steady resting state. Take this scenario as an example, if a person exercises, there will be an increase of the heart rate, which will also result to higher blood pressure. The process of homeostasis will then accommodate the body through different mechanisms to make the decrease of the heart rate possible and at the same time reduce the high blood pressure. It is through homeostatis by which the normal body functions are maintaned in order to sustain life.

pluripotent

Explanation:

A cell that can differentiate into all cell types of the adult organism are called

"pluripotent". Like cells are named meristematic cells in higher plants and embryonic stem cells in animals, though some groups report the presence of adult pluripotent cells.
