18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.

Answers

Answer:

c

Explanation:

they would have diffrent gene versions and protines to get their colors

In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

What is the petal shape dependent on?

Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.

Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.

Answers

Answer:

Active transport.

Explanation:

The kidney uses active transport  to move these substances from the nephron to the  renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the  renal vein.

Select one:

A. Plants store genetic information in the nucleus of their cells

B. Plants are motile primary consumers

C. Plants are multicelular

D. Plants are autotrophic

Answers

Answer:

D. Plants are autotrophic

Explanation:

Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.

Answers

Answer:

c . Process 1 describes cloning and process 2 describes artificial selection.

Explanation:

Process 1 describes cloning because offspring is produced that are similar to its parent and we know that in cloning, the offspring is identical to their parents while on the other hand, process 2 describes artificial selection because crossing between a high-yielding fruit variety with a high-vitamin variety is done which is only possible through the intervention of humans.

Which of the following is NOT a function of an antibiotic?
A. targeting the ribosome that inhibits protein synthesis, causing the cell to not function correctly
B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy
C. inhibiting the production of the cell wall and breaking down what is present​

Answers

Answer:

B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy

Explanation:

Antibiotics can't attack on the mitochondria of the cell because mitochondria provides energy to the cell. Mitochondria is also known as power house of the cell means that it provides energy to the cell in order to continue its activities. If antibiotic attack on mitochondria of the cell, the cell has no energy for performing its activities that leads to cell death so that's why we can say that antibiotic can't attack on the mitochondria of the cell.
