Answer:
electron microscope
Explanation:
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects.
Membrane proteins may extend partway into the plasma membrane and cross the membrane entirely or be loosely attached to its inside or outside face
Answer:
During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.
Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.
In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.
In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.
Answer:
The graph shows that the population of bacteria is increasing with the passage of time. During 1st hour, the population of bacteria is 50 per ml. In second hour, the population is doubled i. e. 100 per ml. In the 3rd hour, the population reaches to 200 per ml and in 3 and half hours, the population touches the value of 300 per ml. So the graph clearly shows that population is double with each hour.
Answer:
A
Explanation:
Bacteria use binary fission but viruses don't
