Phenylketonuria (PKU) is a recessive human disorder in which an individual cannot appropriately metabolize the amino acid phenyl
lutik1710 [3]

Answer

b. Regulate the diet of the affected persons to severely limit the uptake of the amino acid.

Explanation:

<u>This is the effective way of  managing PKU, if diet is not regulated, the blood plasma  Phenylketonuria levels continue to build up  from usual protein consumption. This leads to toxicity of the brain  and brain  dysfunctions. Nausea constipation, fatigues, health headaches are some of the results of the build up</u>.

Therefore to reduce the blood build up of phenylalanine and thus PKU;  Special diet  formulas rich in essential amino acids, and other needed nutrients which may be absent  in phenylalanine low diet  should be  adopted. Amino acids substitutes notably Tyrosine which  is lacking  from  failure of  phenyalanine breakdown in  phenylketouria is heavily  supplemented. Tyrosine is   important  in brain function for alertness, focus,nervous communication.

The  adoption of protein substitutes diet or regulated amino acid diet  is very important because , all the needed amino acid are available , thus protein catabolisms  which may  trigger phenylalanine build up  from muscles and liver storage withdrawal   is prevented thus  stabilizing its blood concentration.

Tay-Sachs, which is a recessive lethal disease, results only when individuals possess two copies of the disease-causing allele.
VashaNatasha [74]

Answer:

a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.

Explanation:

Tay-Sachs, which is a recessive lethal disease  ---- Let say the recessive lethal diseases is s

∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.

Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.

Let show an illustration for the above statement.

Let the heterozygous individual be Ts, if Ts cross with another Ts;

we will have:

Ts × Ts

         T          s

T        TT        Ts

s        Ts          ss

the offspring are TT,Ts,Ts,ss

We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).

This is the force of attraction between an object and the earth due to gravity.
weeeeeb [17]

Answer:

Gravitational force

Explanation:

Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.

In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.
