Choose all correct answers.


The phloem moves the food made in the shoots to all the other parts of the plant.

Vascular plants have leaves that absorb the water and minerals from the air.

The shoots are where the plant makes its food.

Hollow tubes called xylem carry the water and minerals up through the plant to the shoots.

Answers

Water and minerals are transported and used in vascular plants through :

A) Phloem moves the food made in the shoots to all the other parts of the plant D) Hollow tubes called xylem carry the water and minerals up through the plant to the shoots C) The shoots are where the plant makes its food

Transportation in Vascular plants

In vascular plants the root hairs in the root take up water and minerals from the soil and this water and mineral is transported to the shoot and leaves of the plants through a tissue known as Xylem.

The phloem transports the food made by the plants which is in the form of organic nutrients such as amino acids.

Hence we can conclude that the correct options to your question are as listed above.

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.

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.
