A mutation in the HBB gene can cause the formation of haemoglobin S (HbS) which leads to sickle cell disease. So, in this case the mutation is harmful. On the other hand, people who are heterozygous for the mutant allele are resistant to malaria and in this case mutation is beneficial.

A mutation in EYC3 gene is neutral, because the change of eye color is either beneficial or harmful.

A mutation in CFTR gene is harmful, because malformed CFTR protein can't perform its key function in the cell. As a result, the balance of Cl and fluids is disrupted, causing mucus in various organs to become thick and sticky.

A mutation in LRP5 causes high bone mass and consequently, many bone density related diseases. So, this mutation is harmful.

Which of the following soil samples is the most porous? Click on the picture until it shows the correct answer.

bulgar [2K]

Answer:

The second picture showing big rocks with the gaps between where they touched empty.

Explanation:

The figure shown in picture 2 will be the most porous as it does not comprise of any blocking particles. I t will be well sorted and will allow small molecules to easily pour through it.

On the other hand, the other figures like figure 3 will not have much porosity as the path is blocked by many large and small rocks in the image. Hence, it is not the correct option.

An aquifer is a rock layer that stores and allows the flow of groundwater. Compared to other types of rock layers, how permeable

AVprozaik [17]

Highly porous and permeable

Explanation:

Compared to other types of rock layers, an aquifer is highly porous and permeable.

Aquifers are always the target when prospecting for ground water in a formation.

Porosity is the amount of void spaces in a rock.
Aquifers are highly porous .
Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
Aquifers have very high permeability compared to other rock types.

In terms of permeability and porosity, an aquifer is higher porous and permeable.

Alkaptonuria is an infrequent autosomal recessive condition. It is first noticed in newborns when the urine in their diapers tur

Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

Aa x Aa

Progeny: AA 2Aa aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

AA x aa

4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0
