Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
Answer:The rocks are smooth due to the water eroding the rocks.
Explanation:
The water slowly takes off minerals of the rocks every time is splashes over them. Over time the rocks bumpy surface would be eroded away giving it a smoother surface.
Answer:
Population trend refers to changes over time and can include changes in ranging behavior (e.g., distance and route) and distribution, biogeography (e.g., size of population) and life-history (e.g., birth and death rates).
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
