describe how energy for the photosynthesis reaction is gained by plants (2)

please help ​

Answers

Answer:

Plzzzz answer fast......

The energy for the photosynthesis reaction is gained in the first stage of the reaction.

There are 2 stages in photosynthesis:

The light-dependent stageThe light-independent stage

During the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.

The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.

The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

What takes place to the body of a fruit fly if the Hox gene is altered?

When there is Homeotic mutations in fruit flies, Homeotic genes are said to be the reason or the option that is used in knowing the identity of some specific segments or structures of the body.

If an homeotic genes is said to be inactivated or when expressed in an unusual part of the body due to mutations,  it may make the body segments to take on new form.

In Drosophila, that is the fruit fly, a Hox mutation can create a lot of changes such as an extra pair of wings, new a set of legs, etc.

In a population with 100 rabbits there are 16 that are albino, with two
recessive genes for albinism. In this population, what is the gene
frequency for the albino allele?
16
16
0.4
0.84

Answers

Answer:

The gene frequency for the albino allele is 16%.

Explanation:

Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:

16/100 = X

0.16 = X

1 = 100

0.16 = X

0.16 x 100 = X

16 = X

Therefore, the gene frequency for the albino allele is 16%.
