what function does the electron transport chain play in the light- dependent cycle of photosynthesis ?

Biology
1 answer:
romanna [79]3 years ago
5 0

Answer:

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

A man pushes a lawn mower with a force of 200N across 50N meters of his lawn. How much work did the man perform?
krok68 [10]
Work is equal to force times distance or W = Fn x d

In this situation, you would use the following equation:
W= 200N x 50N

W= 10,000N

The man performed 10,000N of work.

Mom is A+. She has 2 children, one is O+ and the other is B-. (Note: Rh+ is RR or Rr, and Rh- is rr) What are the father’s possi
mezya [45]

Answer:

  • The blood group of the father must be B.
  • The genotype of blood group would be I^{B}i.
  • The Rh factor of the father can either be positive or negative.
  • Thus, the genotype of Rh factor of father would be either Rr or rr.

Rh factor:

The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.

If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.

The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.

Blood group:

The blood group of the mother is A. Thus, the genotype can either be I^{A}I^{A} or I^{A}i.

However, the blood groups of the children are O+ and B+.

Thus, the genotype of the mother must be heterozygous that is I^{A}i.

The blood group of the father must be B with genotype I^{B}i in order to produce offspring with blood group O and B.

Determine whether the statement is true or false, and
ryzh [129]

Only males can be carriers for X-linked recessive traits,  False, it should read "Only females can be carriers for X-linked recessive traits."

<h3>What is an allele in a gene?</h3>

An allele is defined as an allele is a variant form of a gene.

For example, if both of your parents have green eyes, you might inherit the characteristic of green eyes from them.

Or if your motherhas freckles, you might have freckles too because you inherited the characteristic for freckles

Thus, option "A" is correct.

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr
alexandr402 [8]
In order to answer this, you will need to set up a Punett Square (I have attached a picture). 

Since Rr is the genotype of round seeds, we know that round must be dominant to wrinkled, and therefore represented by the allele, R.

Since rr is the genotype of wrinkled seeds, we know that wrinkled must be the recessive trait, and there represented by the allele, r.

Since the Punnett Square shows that the genotype ratio is 2Rr : 2rr, or simplified, 1Rr : 1rr, we now know that there is a 50% chance the offspring will have wrinkled seeds.
