Sequence for the movement of electrons during the light dependent reaction

Explanation:

1.These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.

2.The cyclic light-dependent reactions occur only when the sole photosystem being used is photosystem I. Photosystem I excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b6f, to another transport protein, plastocyanin (Pc), and back to photosystem

3.Light-dependent reaction. In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). ... Water, when broken, makes oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and by chemiosmosis, make ATP

4.The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?

yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

What are the chances that a kitten born would have a DIFFERENT genotype than the sister's cat Moo?

Strike441 [17]

A kitten born will have genotype different from sister because the concentration of gene expressed is different in all kittens as it is a phenomenon of codominance.

Explanation:

The moo cat is black and white bicolour cat.

The cat has white colour fur which is combined with some other colour as black.

White colour in cat has white spotting gene that prevents the patches over cat's body.

SS genotype results in large concentration of white colour.

Ss results in medium concentration of white colour.

ss results in black or other dark colurs with very meager or no white colour on skin.

The resultant colour appearance of skin in cats is due to codominance. The colour of the skin depends on the concentration of gene and protein expressed. So, the sister moo cats can have diffrent genotype and different level of white colour patches on the skin and genotype of SS,Ss or ss can be there in sister kittens.

How do hormones relate to the estrous cycle?

choli [55]

Answer:

Estrous cycles give females repeated opportunities to become pregnant throughout their productive lifetime. The cycle is regulated by the hypothalamic-pituitary-gonadal axis, which produces hormones that dictate reproductive events.
