The answer is option c.
 That is, the wrong step in step 6. It was written that the center of the circunference is the point (2.1). However, the general equation of a circumference is:
 (X- (a)) ^ 2 + (Y- (b)) ^ 2 = r ^ 2
 Where the point (a, b) is the center of the circle.
 So for this case the point for the center is: (-2, -1)

Assume that long earlobes in humans are an autosomal dominant trait that exhibits 30% penetrance. A person who is heterozygous f
Bess [88]

Answer:

0.75

Step-by-step explanation:

Autosomal dominant: A pattern of inheritance in which an affected individual has one copy of a mutant gene and one normal gene on a pair of autosomal chromosomes

Heterozygous just means that a person has two different versions of the gene (one inherited from one parent, and the other from the other parent).

Being homozygous for a particular gene means you inherited two identical versions.

The trait is autosomal dominant so the characters pass into the next generation in a large ratio. the person who is heterozygous for the character have two type of allele which represents the trait for long earlobes and also for short earlobe.So a person is paired with homozygous individuals who have pure character for short earlobes.The percentage of their first child with long earlobes would be 75 percent. This is due to the dominance of the character in a generation.

How does the graph of g(x) = (x - 3)^3 + 4 compare to the parent function f(x)=x^3 ?​
masha68 [24]

Answer:

f(x) has moved:

4 units in the positive y direction i.e upwards

3 units in the positive x direction

Step-by-step explanation:

to get g(x), f(x) has undergone the following transformations

f(x) = x³

f1(x) = x³ + 4      (translation of 4 units in the positive y direction i.e upwards)

f2(x) = g(x)  = (x-3)³ + 4 (translation of 3 units in the positive x direction i.e towards the right)
