Flagellum is primarily a motility organelle that enables
movement and chemotaxis. Bacteria can have one
flagellum or several, and they can be either polar (one or
several flagella at one spot) or peritrichous (several
flagella all over the bacterium).
If sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient and the voltage across the membrane (the more negative charge on the inside of the membrane). So cells pump out the extra ions.
This is what my candidate teacher said..
Answer:
a. ribosome
Explanation:
Ribosome -
The ribosome is common in both the cells of eukaryotes and prokaryotes .
Ribosomes acts as a site for protein synthesis .
Ribosomes are present even on the endoplasmic reticulum .
They link the amino acids with the messenger RNA molecules , which is used for the sequencing of the amino acid to obtain proteins .
The amino acids are carried with the help of the tRNA molecules .
hence , the correct answer for the given information is ribosome .
The two principal types of connective tissue in a
muscle are collagen and myofibrils. The entire muscle is wrapped in collagen to
form a fascicle. Looking at one muscle fiber, you will see that almost the
entire cross section of the muscle fiber is composed of long, cylindrical
strands of proteins called myofibrils<span>. </span>
