Answer:

Since albinism is an autosomal recessive trait, it means that both parents must possess the gene for it, for the albinism to occur.

Thus, David could be the father if both Rose and David are carriers(heterozygotes) for the albino allele.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

Explain how the heliocentric model has been modified with the help of telescopes and probes ?
baherus [9]

Answer:

They collect more information.

Explanation:

The heliocentric model has been modified with the help of telescopes and probes because telescopes and probes collect more accurate information about the solar system and planets. Due to information collected from these instruments, scientists are able to modify the heliocentric model more accurately. So we can conclude that with the help of telescopes and probes, the heliocentric model has been modified.

KatRina [158]

Answer:  <u>Fascism</u> rejects the ideas of individual freedom and equality, instead arguing that hierarchies of superior and inferior are inherent in all human relationships.

Explanation:  

Government that plays a role like a one party dictatorship followed fascism. In fascism nation's rights come before the rights of an individual. Countries that followed fascism run by a centralized government headed by a dictator. Fascists governments try to control all aspects of life including work, school,social and family life etc. Fascism is much common and practiced ideology around the time of world war 2.
