what molecules do plants take in for their energy needs

Answers

Answer:

Photosynthesis is the process by which plants produce food. Plants use their leaves to trap light energy during photosynthesis. Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to manufacture cellulose and starch, among other things.

Another explanation:

Also, photosynthesis is a chemical reaction that takes place in a plant's leaves and requires both chlorophyll and light energy. Chlorophyll in leaves aids in the conversion of carbon dioxide and water into oxygen and glucose during photosynthesis. Glucose serves as a critical source of nutrition for the plant.

What is a gene?

A gene is a specific section of DNA, a long molecule that carries genetic information, located on a chromosome. Genes contain the instructions that cells use to make functional molecules called proteins.

Proteins are large molecules that perform a wide variety of functions in the body, including speeding up chemical reactions (as enzymes), building and repairing tissues, and helping to fight infections.

The process by which genetic information in a gene is used to build a protein is called gene expression.

Thus, genes play a critical role in determining the traits and characteristics of an organism, and they are essential for the proper functioning of cells and tissues in the body.

5.) Morgan buys a male python from a snake dealer who tells him that the snake carries the albino allele. Morgan mates the snake with an albino female, and ten normally pigmented offspring are produced with zero albino offspring. Morgan rushes back to the snake dealer and demands his money back stating that the male he bought is not heterozygous for the albino allele because all of its offspring had normal pigmentation. Is Morgan’s position supported by genetic theory? Why?

Answers

From the illustration, Morgan's claim could be valid and his position is supported by genetic theory.

Dominant/recessive alleles

It can be inferred from the claim of the snake dealer that albinism in male python is a recessive trait. If this claim is true, let us assume that the albino allele is represented by b and the alternate form is B.

The genotype of the snake Morgan bought will be Bb as claimed by the dealer.

Morgan mated Bb snake with an albino snake which would be bb.

              Bb    x    bb

             Bb   Bb   bb   bb

Thus, the mating should have produced albino to non-albino snakes in the ratio 1:1.

Sophia wrote an equation to represent the revenue of a movie theater for one day. She let x represent the number of child tickets sold and y represent the number of adult tickets sold. If a child ticket costs $4, an adult ticket costs $6, and the total revenue for the day was $420, which equation could Sophia use to represent the number of child and adult tickets that were sold?
6 x + 4 y = 420
4 x + 6 y = 420
4 x + 6 y = 840
6 x + 4 y = 840

Answers

Answer:

4x + 6y = 420

Explanation:

since x is number of child tickets and y is adult tickets, and $4 is the cost of child tickets and $6 is the cost of adult tickets, that eliminates A and D.

The question also states "for one day", so that elimates C, which C is the equation for two days.

This leaves 4x + 6y = 420
