Answer: The correct answer is 1/2

Explanation:

Based on Mendel's 2nd law - the law of independent assortment of genes - each character behaves as a separate unit and is INHERITED independently of any other character.

So, Aa will separate in two alleles "A" and "a". And by the law, each will be received by the gametes in equal rate of 50:50 i.e 1/2.

So for"A" allele, it is 1/2

Which of the following best describes the solar radiation absorbed by and radiated from earth?
vovangra [49]

Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.

Explanation:

In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.
