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).
Answer:
The organelle that conduct respiration for the cell is MITOCHONDRIA.
Explanation:
The cells of living organisms are made up of different organelles, each of the organelles have specific functions, which they perform. The mitochondria is the cell organelle that is responsible for carrying out respiration in the cells. Respiration involves the breaking down of glucose molecules in order to produce energy in form of ATP. Mitochondria is also called the power house of the cell because of its function of energy production.
