Answer:

eight (8)

Explanation:

A phenotypic ratio of 9:3:3:1 is predicted from a cross of AaBb x AaBb (i.e., in a dihybrid cross). In this case, the expected phenotypic ratio is equal to:

A_B_ (9:3:3:1) =71.43 >> 71 both dominant phenotypes

aaB_ (9:3:3:1) = 23.81 >> 24 one dominant phenotype

A_bb (9:3:3:1) = 23.81 >> 24 one dominant phenotype

aabb (9:3:3:1) = 7.93 >> 8 both recessive phenotypes

Expected phenotipic ratio (9:3:3:1) = 71 + 24 + 24 + 8 = 127

PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surro
Anuta_ua [19.1K]

Answer/Explanation:

Recall:

Volume of a sphere = ⁴/3πr³

Surface Area = 4πr²

✔️For radius (r) = 1 mm:

Volume = ⁴/3 × π × 1³ = 4.19 mm³

Surface Area = 4 × π × 1² = 12.57 mm²

Ratio of volume to surface area = 4.19 : 12.57 = 1:3

✔️For radius (r) = 3 mm:

Volume = ⁴/3 × π × 3³ = 113.1 mm³

Surface Area = 4 × π × 3² = 113.1 mm²

Ratio of volume to surface area = 113.1 : 113.1 = 1:1

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous
9966 [12]

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.

<h3>What is heterozygous?</h3>

The occurrence of different types of alleles is referred to as heterozygous condition.

A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.

The missing options of the question are:

  1. Yy ´ yy
  2. YY ´ yy
  3. Yy ´ Yy
  4. yy ´ yy

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.

Thus, the correct option is A.

If phosphofructokinase experienced a mutation that interfered with substrate binding, then what other enzyme is going to be most
frozen [14]

Answer: Aldolase

Explanation:

In the metabolism of glucose( glycolysis) phosphofructokinase is an enzyme that catalyzes the conversation of fructose-6-phosphate into fructose-1,6-bisphosphate. This in turn is converted to pyruvate after various steps of enzymatic activity in the glycolytic pathway.

If phosphofructokinase experienced a mutation that interfered with substrate binding, the enzyme that is going to be most immediately impacted in terms of accessing substrate is the ALDOLASE.

Aldolase enzymes cleave fructose-1,6-bisphosphate to triose phosphates( glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate) facilitating an increase in anaerobic production of ATP in muscle.

Therefore, the substrate for binding of aldolase, which is fructose-1,6-bisphosphate is lacking due to mutation of phosphofructokinase enzyme.

The great scientist Isaac Newton said that his long studies of the moon gave him headaches.What do you think is complicated stud
Oduvanchick [21]
Well, using Math to see how far the Moon is from the Earth could be hard. Also, he saw that the Moon is moving in a "circle" instead of flying off, so the Earth did have a pull on the Moon so that it didn't fly away. Newton had to use Math in order to be able to identify what it's now called gravity. There's a lot that the Moon has to offer, there were no computers back then, so there's was no calculator and everything had to be done by hand.
