Electrons are excited in photosystem I. What do these electrons combine with in order to produce an energy-carrying molecule?
Elenna [48]
Below are the choices that can be found elsewhere:

a. ADP 

<span>b. ATP </span>

<span>c. glucose </span>

<span>d. NADP+
</span>
The answer is d. NADP+ 
<span>The electrons combine with NADP+ molecules to form NADPH molecules. The NADPH molecules then travel to the stroma of the chloroplast to carry out the Calvin cycle. The Calvin cycle then produces glucose, which is the energy carrying molecule. The glucose molecule is used in cellular respiration to make ATP, so the cell can harness the energy from the glucose molecule.</span>

In fruit flies, long wings (W) are dominant over short wings (w), and brown pigments (N) are dominant over yellow pigments (n).
Law Incorporation [45]

Answer:

WwNn

Explanation:

  • Long wings (W) are dominant over short wings (w)
  • Brown pigments (N) are dominant over yellow pigments (n)

A fly that is homozygous dominant for both traits (WWNN) is crossed with a fly that is homozygous recessive for both traits (wwnn).

All gametes produced by the WWNN individual will be <em>WN,</em> and all gametes produced by the homozygous recessive individual will be <em>wn</em>.

When the gametes from the two parents combine, the zygote will be heterozygous for both genes, with the genotype WwNn.
