Which of the following factors is needed during light-dependent reactions to create ATP and NADPH energy molecules?

Alexeev081 [22]

Answer: The correct answer is- Solar energy, carbon dioxide, and water.

Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.

This phase occurs in the thylakoid membrane of chloroplast.

During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.

This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.

In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.

Thus, solar energy, carbon dioxide, and water is the right answer.

I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is

Tt x tt (heterozygous crossed with a homozygous recessive)

The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.

So the percentage of offspring that are homozygous recessive is 50%.

Part 1- Explain which traits would need to combine in order for a yellow cucumber and a green to make a green cucumber.

adelina 88 [10]

<h2>Part 1.</h2><h2>Answer:</h2>

Only the traits or allele for the green trait will be needed to make a green cucumber.

<h3>Explanation:</h3>

Here in the given example there are two allele responsible for the color of cucumber. One is Y which is dominant allele and codes for the yellow color.

While y is recessive allele and it will be code for the green color.

In case of heterozygous in which the genotype will be Yy but the phenotype will be always yellow because Y is dominant.

In case of genotype yy the phenotype will be green.

So for green cucumber there will be two y in the genotype.

<h2>Part 2.</h2><h2>Answer:</h2>

For yellow cucumber, there is need of only one dominant allele which codes for yellow.

<h3>Explanation:</h3>

According to the given punnet squre, There will be 4 genotypes from the breeding of a yellow cucumber and green cucumber.

The yellow cucumber is heterozygous or homozygous and its genotypes can be Yy and YY relatively.

But for green cucumber the genotype can only be homozygous which is yy.

In the punnet squre the 2 phenotype are yellow and green.

Hence for the yellow cucumber there is only need of one Y allele in genotype.
