Other hardness test never gain that much popularity as Mohs scale.Its a relative integer scale comparison of being scratched. Other hardness test in which a specific pressure applied for a specific length of time.An example of a mineral with variable hardness is kaynte. Another best example is diamond with variable hardness people who cut diamond have known its variable hardness, In Mohs scale of hardness diamond 's position is number 10-10000 is its hardness.

Which of the following statements regarding Entner-Doudoroff pathway is true?
Sindrei [870]

Answer:

C. ATP is generated

Explanation:

The Entner-Doudoroff pathway is one of the three glycolytic pathways that breakdown glucose into pyruvate. The Entner-Doudoroff pathway is the most common glycolytic pathway in microbes present in the soil such as <em>Rhizobium, Azotobacter,</em> etc.

The Entner-Doudoroff pathway forms glucose 6-phosphate from glucose which in turn is oxidized into 6-phosphogluconate. The 6-phosphogluconate finally forms pyruvate and glyceraldehyde 3-phosphate through a series of reactions. The glyceraldehyde 3-phosphate can enter the Embden-Meyerhof pathway to form one more molecule of pyruvate. During the Entner-Doudoroff pathway, one molecule of ATP and one NADPH are formed along with the formation of one molecule of each pyruvate and glyceraldehyde.

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eye
Ivenika [448]

Answer:

PpDD and PpDd

Explanation:

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).

The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be  PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.

The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.

In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).

<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.
