4. Cystic fibrosis is a homozygous recessive condition that affects 1 in 10,000 of the Hispanic population
in the United States. Calculate the frequency of the dominant allele, the frequency of the recessive allele, and the percentage of heterozygous individuals (carriers) in the Hispanic population.
Frequency of the dominant allele Frequency of the recessive allele
% homozygous dominant
% homozygous recessive
% heterozygous
Answers
The frequency of the dominant allele is 0.99, the frequency of the recessive allele is 0.01, and the percentage of heterozygous individuals (carriers) in the Hispanic population is 1.98%.
What is Frequency?
Frequency refers to the number of occurrences of a particular event or phenomenon in a given unit of time or space. In genetics, frequency typically refers to the number of occurrences of a particular allele or genotype in a population. For example, the frequency of a particular allele in a population is the proportion of that allele in the total number of alleles at the same locus in that population.
To calculate the frequency of the dominant and recessive alleles, we can use the Hardy-Weinberg equation:
Since cystic fibrosis is a homozygous recessive condition, we know that \(q^{2}\)= 1/10,000, or 0.0001. We can solve for q by taking the square root of both sides:
q = √(0.0001) = 0.01
To find p, we can use the fact that p + q = 1:
p = 1 - q = 1 - 0.01 = 0.99
So the frequency of the dominant allele is 0.99, and the frequency of the recessive allele is 0.01.
To calculate the percentage of heterozygous individuals (carriers), we can use the equation:
2pq * 100%
where 2pq represents the frequency of heterozygous individuals. Plugging in our values, we get:
2pq = 2(0.99)(0.01) = 0.0198
So the percentage of heterozygous individuals in the Hispanic population is:
0.0198 * 100% = 1.98%

A radioactive element has a half-life of 2 days. What percentage would remain radioactive after 6 days? b. If the original mass was 120 grams, how much would have decayed after 6 days?
Answers
Answer:
The correct answer is -
A. 12.5%
B. 105 grams.
Explanation:
Half-life is the amount of time requires to decay or convert half of the atoms of the compound or element. It is denoted by the t1/.
In this question, it is given that an element has a half-life of two days which means it becomes half of the initial amount in two days.
A. So, after six days the percentage of the amount remaining that would be
= 50*1/3
(6 days = three half-life cycle) and (one-half cycle = 50% of initial value)
= 12.5% of its initial value.
B. If the original amount of the element was 120 gram then the amount of element that decayed in six days would be:
= Initial value - remain value
= 120 - (120*12.5/100)
= 120 -15 grams
= 105 grams.

Are the cells able to move on their own? Whyor why not?
Answers
Answer:
Yes, some cells are able to move on their own. This type of movement is known as cell motility, and it is a crucial aspect of many biological processes, such as embryonic development, wound healing, and immune response.
There are different mechanisms by which cells can move. Some cells, such as bacteria and sperm cells, have flagella or cilia that allow them to swim or move through fluids. Other cells, such as white blood cells, use a process called amoeboid motion, where they extend and retract membrane protrusions to move forward.
In addition, some cells are able to migrate through tissues and organs by sensing and responding to chemical cues in their environment. This type of movement is known as chemotaxis, and it allows cells to move towards or away from specific chemicals.
So, in summary, while not all cells are able to move on their own, many types of cells have the ability to move through various mechanisms.

Answers
Answer:
The X₀ frequency is 0.26
The X+ frequency is 0.74
Explanation:
Available data:
The orange coat color of cats is due to an X-linked allele (Xo)X₀ is codominant with the allele for black X+X₀X₀ 11X₀X+ 70X+X+ 94X+ Y 112X₀ Y 36To alculate the frequency of the X₀ and X+ alleles you need to sum the times it appears X₀ and the times it appears X+ alleles in the population. These sums will give you the number of alleles. As you need to calculate the frequency of these alleles, you will have to divide each number by the total number of both alleles together. This is:
X₀ = 2 x (X₀X₀) + (X₀X+) + (X₀Y) = (2 x 11) + 70 + 36 = 128X+ = 2 x (X+X+) + (XoX+) + (X+Y) = (2 x 94) +70+ 112 = 370The total number of alleles in the population is 128 + 370 = 498
To talculate the allele frequencies, f, you need to divide each allele number by the total allele number:
f (X₀) = 128/498 = 0.26
f (X+) = 370/498 = 0.74
what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
Answers
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

metabolism
Answers
Answer: metabolism
Explanation:
Many people think that metabolism is just the process of creating energy, but it is so much more than that. However, any chemical process that occurs in the body with the idea of being life-sustaining is considered metabolism. The rate of metabolism varies from person to person, with some people having faster metabolism than others.
The term metabolism refers to all chemical reactions occurring in the body. Therefore, option D is correct.
Metabolism contains a wide range of processes involved in the conversion of nutrients into energy, the synthesis of molecules needed for cellular activities, and the breakdown of substances for elimination.
Metabolism is of two types and that is anabolism and catabolism. Catabolic reactions involve the breakdown of larger molecules into smaller ones, releasing energy in the process. Anabolic reactions involve the synthesis of larger molecules from smaller components, requiring energy input.

The parents, Michael and Danielle, both have light brown skin and the Bb genotype. Draw a Punnett square and explain how these parents could have two babies with different color skin- one dark brown and the other tan.
Answers
Answer:
n order to create a Punnett square, we need to list the possible gametes (sex cells) that each parent can contribute to their offspring. Since Michael and Danielle both have the Bb genotype, they can each contribute a B or a b allele to their offspring.
Possible gametes for Michael: B or b
Possible gametes for Danielle: B or b
Using these gametes, we can create a Punnett square to show the possible genotypes of their offspring:
B b
B BB Bb
b Bb bb
From the Punnett square, we can see that there are four possible combinations of alleles for their offspring: BB, Bb, Bb, and bb.
BB: This offspring would have two dominant B alleles, resulting in dark brown skin.
Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.
Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.
bb: This offspring would have two recessive b alleles, resulting in light skin.
Therefore, it is possible for Michael and Danielle to have two babies with different skin colors, one with dark brown skin and the other with tan skin, due to the combination of their different alleles in their offspring.
