Answer:

B) when starch is broken down into sugars

Explanation:

In living beings, decomposition reactions break down the complex substances into simpler elements. Starch is a polymer of glucose and is a large and complex molecule.

During digestion or breakdown of starch, it is broken down into its simpler constituent glucose. Since the complex sugar starch is digested into the simple sugar (glucose), it is an example of a decomposition reaction.

The picture shows the dihybrid cross of 2 guinea pigs.
kramer

Picture from another source is attached

Answer:

1. BbRr

2. Black, rough fur

3. bbRR

Explanation:

1. The genotype of the parents can be seen at the top of the cross "BbRr". The genotype is what alleles the parents have. In this case, it is the alleles of two different genes - for color and texture of fur. The genotype gives rise to 4 possible allele combinations that an offspring can inherit (BR, Br, bR or br)

2. The dominant allele is usually displayed as a capital letter, and the recessive as lowercase. Without further information, we will assume this is the case. The parents are heterzygous for both traits, meaning they each carry a dominant and recessive allele for both traits. That means the dominant allele will be expressed in the phenotype. Therefore, the guinea pigs will have black, rough fur.

3. Empty box shown in the attachment. We simply read the column and row  of alleles that are contributing to this offspring's genotype. We can see looking at the square that from one parent (top) the baby will inherit bR, and from the other parent (left) it will inherit bR as well. This means the baby's genotype will be bbRR

The proportions of the bases are consistent within a species; however they do vary between species. Using the base-pair rules, c
Snezhnost [94]

Answer:

The correct answer would be:

                  A         G          C         T

Human:   31          19          19       31

Cow:         28         22      22         28

Salmon:     29       21       21         29

Wheat        27      23        23        27

Yeast         31         19       19         31

Explanation:

According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.

It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:

                    A         G          C         T

Human:   31          19          19       31   (A= T and G=C)

Cow:         28         22      22         28  (A= T and G=C)

Salmon:     29       21       21         29   (A= T and G=C)

Wheat        27      23        23        27 (100 - A+T = G+C)

Yeast         31         19       19         31 (A= T and G=C)
