3 0

Answer:

The correct answer will be option- true.

Explanation:

The evolution of humans can be just predicted on the basis of the evidence found like fossils which represented the ancestor of humans.

On the basis of these fossils, the oldest fossil found was the fossil which belonged to the Pliocene and Pleistocene epochs around 4.4 million to 1.4 million years ago (mya).

The fossil belonged to the species of the genus Australopithecines the most famous of which is Lucy. This fossil bear the characteristics of both humanlike and apelike characters traits like bipedalism, increased brain size and canine teeth. So they are considered the ancestors of the human lineage.

Thus, option-true is the correct answer.

An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.
Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

  • The concentration of hydrogen ions is inversely related to its pH
  • More hydrogen ions present, the lower the pH
  • The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,    

=> 5 = -log (H+)

=> H+ = 10^{-5} (for pH = 5)    

=> pH = -log(H+)  

=> 6 = -log (H+)  

=> H+ = 10^{-6}  (for pH = 6)  

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

Phenylketonuria (PKU) is an autosomal recessive disorder where afflicted individuals are incapable of metabolizing the amino aci
zvonat [6]

Answer:

25%

Explanation:

Let's assume that the recessive allele "p" imparts diseased conditions in the homozygous genotypes. The genotype of each of the carrier parents would be "Pp". A cross between Pp and Pp would produce progeny in the following phenotype ratio=

Pp x Pp= 3/4 Normal : 1/4 Affected.

Therefore, there are 1/4 or 25% chances for this couple to have a child with PKU.
