why is a dominant acele called dominant
Answer:
Dominance is a relationship between two alleles of a gene and their associated phenotypes.
A "dominant" allele is dominant to a particular allele of the same gene that can be inferred from the context, but it may be recessive to a third allele, and codominant (both appear in the organism) to a fourth.

Why is it important to center the object you want to look at in your field of view before changing to a higher magnification objective lens? A. So the object is still in your field of view at the higher magnification. B. So you can always see the entire object at the higher magnification. C. So you do not damage the higher magnification objective lens.
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.
Q. Why is energy required by an organism even during sleep ?
Q. Give the energy transformation that takes place in the process of photosynthesis.
Q. What is chlorophyll ?
Q. Name the various factor which affect the rate of photosynthesis.
Q. Define photolysis.
➥ Even, when an organism is asleep, various biological processes keep on occurring in its body which requires energy.
➥ During photosynthesis‚ “Solar energy is converted into chemical energy”.
➥ “Chlorophyll” is a green coloured pigment found in plants that helps in absorbing sunlight used in photosynthesis.
➥ Several factors which affect the rate of photosynthesis:
Light. Temperature. Water.CO2.➥ “Photolysis” is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen.
