Answer:
A. The rice genes didn't make the right type of vitamin A.
Explanation:
Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.
To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.
This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.
Answer:
The correct answer would be large NA
The resolution of a microscope is defined as its ability to distinguish two closely placed points as different entities.
The NA or numerical aperture of an objective is defined as the ability of a microscope to gather light.
NA determines the resolving power of the microscope that is, the higher the NA the higher will be the resolving power of the microscope.
However, the total resolution of any microscope also depends upon the NA of the substage condenser.

Explanation:
As water temperature increases, the amount of O2 dissolved in water decreases.
The graph looks something like this (though not exactly. It just has the same sort of shape.)
