Answer:

Mutation takes place in viruses as they occur in a cellular organism, the presence of a large number of mutants in the virus genome give virus population ability to adapt quickly to selective pressures

Some viruses like influenza and HIV virus mutate so rapidly from one host to another host cell that it becomes very difficult for the immune cell to prepare antibodies or for the scientist to prepare a vaccine against the viruses.

What are the products of the light reactions used for during in the dark reactions of photosynthesis?

serg [7]

Answer: Glucose and Oxygen

Explanation: The two products of the light dependent reactions in photosynthesis are glucose and oxygen and are produced through the reconstruction of water and CO2 in the air. The light independent reactions also known as cellular respiration is a process identical to the human cellular respiration where glucose is broken down and rearranged with oxygen to create mechanical energy leaving CO2 and H2O left over.

True-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) a

mina [271]

Answer:

The correct answer is -

Possible F2 offspring genotypes and phenotypes:

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Explanation:

In this case, the genes 's' and 'L' and genes 'S' and 'l' are linked, they will be passed on to the gamete together.

The cross would be as follows:

F1:

Parents: singed bristles and normal wings x normal bristles and vestigial wings

Genotype: ssLL SSll

Gametes: sL Sl

F1: SsLl ( normal bristles and normal wings )

For F2,

Parents: normal bristles and normal wings x singed bristles and vestigial wings

Genotypes: SsLl ssll

Gametes: SL, Sl, sL, sl

Cross:

SL Sl sL sl

sl SsLl Ssll ssLl ssll

Thus the possible offspring will have -

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Albedo is the fraction of incoming light that is reflected by a celestial object. how would you predict a decrease in paved surf

iren [92.7K]

A decrease in the paved surfaces on earth will increase amount of light reflected or increase albedo.

<h3 /><h3>What is a paved surface?</h3>

A paved Surface refers to a surface covered by concrete, asphalt, masonry, or a similar material.

Paved surfaces have low albedo, that is they have low light reflectivity.

<h3>What is the effect of paved surface of Earth on albedo?</h3>

Since paved surfaces have low albedo, a decrease in the paved surfaces on earth will increase amount of light reflected (albedo).
