How do chloroplasts get energy from sunlight?

2 answers:

8 0

When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy. Plants use water, carbon dioxide, and sunlight to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two

Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.

g Describe the structure of Hemoglobin. Does the binding of oxygen involve the direct interaction with the polypeptide chain

Scorpion4ik [409]

Answer:

Hemoglobin is an iron-containing protein present in the blood that functions for transportation of oxygen to different body cells..

Each hemoglobin molecule have tetrahedral structure consist of four heme groups surrounded by a globin group. Heme, is composed of porphyrin (ringlike organic structure) which is attched to an iron atom. There are four iron atoms in each molecule of hemoglobin that binds with four oxygen atoms and globin carry two linked pair of polypeptide chain.

The oxygen reversibly binds with the polypeptide chain and the process called oxygenation.

Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white.

Alinara [238K]

Three out of four of their offspring will be white when Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white. Thus, the correct option is B.

<h3>What is law of dominance?</h3>

A trait is represented by two contrasting factors of a gene in a heterozygous individual, while the homozygous individual has two copies of the identical factors, according to the law of dominance. As a result, the heterozygous rabbit's genotype will be Bb, whereas the homozygous recessive rabbit's genotype will be bb.

FF X ff

Ff (F1 generation)

Ff X ff (self pollination- F2 generation)

║

Ff, Ff, Ff, ff

3: 1 (black: white)
