Tonicity is the measure or amount of the osmotic pressure gradient.
Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.

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.

Echinoderms _____. _____ Select one: a. have an exoskeleton of hard calcareous plates b. often use tube feet to move around in t

atroni [7]

Answer:

B. often use tube feet to move around in their environment

Explanation:

Tube feet are tiny tubular projections of echinoderms on the underside (oral side). They are a member of the echinoderm water vascular system.

Tubular feet are used for feeding, breathing and shifting. They are arranged around the sides, in grooves. They work by hydraulic pressure. They are used to transfer food in the centre to the oral mouth, and may stick to surfaces. Tube feet allow certain animals to stick and travel slowly to the ocean floor. for example starfish uses tube feet for the above functions.

Hence, the correct option is B.

Positive feedback is most like _____.

sesenic [268]

~ B - Adding wood to a burning fire to increase the heat.

A is kind of like a reaction to negative feedback - it's too hot, so cooling down.
C is like turning the air conditioner off. It's cool enough.

B on the other hand adds something to the whole by reinforcing it. The fire is a metaphor for the writer's self-esteem, ego, good-feelingness, what-have-you.
