How does a magnifying glass make an object look bigger and closer?​
ANEK [815]

Answer:

Any converging lens that has a small focal length (several centimeters) can be used as a magnifying glass. The observed object is placed in front of the magnifying glass so that it is located between the lens and the focus (closer to the focus).

Explanation:

It consists of only one condenser lens of small life (a few centimeters).

The observed object is placed between the magnifying glass and its focus (closer to the focus)

The observer sees an upright and enlarged figure of the object.

In order to like clear video ("sharpen"), the magnifier zooms in or out of the subject.

When the character is most clearly seen, we can find ourselves on a given high species.

For a man with normal eyesight, it is about 25 cm.

The immune system has both specific and nonspecific immune responses against pathogens. Which scenario describes a specific immu
vovangra [49]

Answer:

antibodies being produced to fight off a pathogen inside the body

Explanation:

Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.

The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.

Mitosis &amp; Meiosis: Thinking Scientifically
REY [17]

Answer:

65536 cells

Explanation:

starting from 1 cell at zero minutes  there will be 1 (2^0) cell; 2^0 = 1

after 15 minutes                    there will be 2 (2^1) cells

after another 15 minutes ( 30 min)        there will be 4 ( 2²) cells

after another 15 minutes ( 45 min)         there will be 8 (2³) cells

after n number of 15 minutes                  there will be (2^n) cells

calculate number of 15 minutes in 4 hours

4 hours = 4 × 60 minutes

number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16

using the formula above and substitute 16 for n in the formula

Number of cells = 2 ^n = 2^16 = 65536 cells
