The overall magnification of a microscope is calculated by multiplying the objective lens's magnification by the optical lens' magnification.
However, you must first ascertain the optical lens's magnification power before computing the total magnification. The ocular lens typically magnifies 10 times.
Find out how much the objective lens can magnify. On the side of the lens is printed the magnification. The value may formerly be 4X, 10X, 40X, or 100X.
Multiplying the ocular lens' magnification power with the objective lens' power yields the compound light microscope's overall magnification. For instance, a 400X total magnification would be achieved with a 10X ocular and a 40X objective. The compound light microscope has a maximum total magnification of 1000X.

The triangle is an Acute angle triangle.
Answer:
a. True
Explanation:
Biological psychologists study the human behavior, focusing on the psychological causes. Identifying unconscious drives is important in order to understand the reason for this type of unaware reactions on humans. Using different techniques, they can manage to comprehend the origin of this behavior and find a solution to control, and settle this issue.
Answer:
Bacteriophages are attaching to bacterial cell wall and injecting genetic material.
Explanation:
Bacteriophage:
A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.
Following are steps of bacteriophage infection:
- Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
- Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
- The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
- After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
- In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.
* The second step of the infection cycle is pictured here.
