Photosynthesis uses the energy of sunlight to convert water and carbon dioxide (reactants) into high-energy sugars and oxygen (products). ... During light-independent reactions, ATP and NADPH from the light-dependent reactions are used to produce high-energy sugars that can be stored for a long time.

When a protein is treated with a reducing agent such as 2-mercaptoethanol it becomes denatured. The interactions stabilizing the

Andreas93 [3]

Answer:

Disulfide linkage/bond

Explanation:

The tertiary and quarternary structure of the protein is stabilized by Disulfide linkage which is formed between two thiol groups in the protein. 2-mercaptoethanol is a reducing agent that breaks this disulfide bond.

A protein becomes denature when it loses its native configuration and becomes inactive. So as 2-mercaptoethanol breaks disulfide bond in protein it looses its native configuration and becomes denatured. 2-mercaptoethanol is used in SDS-PAGE to separate protein subunits. Therefore the correct answer is Disulfide linkage/bond.

A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with

vesna_86 [32]

Answer:

The dominant curled wing allele is also a recessive lethal.

Explanation:

If we look at the F2 ratio we see that :

curled wings: straight wings= 160:80

=2:1

Hence, if curled wings is considered to be a dominant trait then Curled wings * straight wings

Dd x dd

Punnet square will be as follows :

d d

D | Dd | Dd

d | Dd | dd

Hence in order to get F2

Dd x dd

Punnet square will be the same as above if the F1 cross is Dd* Dd

D d

D DD Dd

d Dd dd

if DD is lethal then the ratio is

Dd:dd=2:1

that is curled wings: straight wings=2:1

Hence, The dominant curled wing allele is also a recessive lethal.
