Answer:
sepals
Explanation:
sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.
Limits to variation The most obvious limit to natural selection is that suitable variation may not be available. This may be because certain phenotypes cannot be built, being ruled out either by physical law or by the properties of biological materials.
Answer:
yes
Explanation:
bcoz it helps in every way
The magnification of the ocular lens of a microscope is x10 and the magnification of the objective lens for low, medium, and high power are 4X, 10X, and 40X, respectively. The measured dFOV under medium power is 2.6mm.
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.
