Merle is a marking pattern in canine coats that appears as a marbling of color in a solid coat. The merle gene displays incomple

Over [174]

Answer:

A)

1. double merle with short coat: 1/4 (e).

2. double merle with long coat: 0 (a).

3. merle with short coat: 1/2 (g).

4. merle with long coat: 0 (a).

5. solid with short coat: 1/4 (e).

6. solid with long coat: 0 (a).

B)

1. double merle with short coat: 3/16 (d).

2. double merle with long coat: 1/16 (b)

3. merle with short coat: 3/8 (f).

4. merle with long coat: 1/8 (c).

5. solid with short coat: 3/16 (d).

6. solid with long coat:1/16 (b)

Explanation:

Available data:

CSCS individuals display a solid coat
CMCS individuals are merle and show patches of fur with a lighter, mottled effect
CMCM individuals are "double merle" and show patches of fur with much more pronounced lightening
short coats, L-, being dominant to long coats, ll.

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?

dezoksy [38]

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

And True- Both ATP and NADPH are needed to make sugars.

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.

H+, and oxygen, are formed from a water molecule as it's broken apart.
From photosystem II, electrons are transferred to photosystem I.
ATP is synthesized from ADP along with inorganic phosphate.
To form NADPHH, H+ is added to NADP

If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).
