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).
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.

Answer:
The normal range of blood glucose is 70–120 mg/dL. A person has a blood glucose level of 170 mg/dL. Based on your knowledge of the endocrine system and hormones, explain the likely cause for the person's condition.
It could be as a result of high sugar intake which increases the individual's blood glucose level
Explanation:
From the assertion above, it could be deduced that the individual pancrease is no more functioning hence; no control of blood glucose level. Furthermore, the continuous intake of sugar or food materials with high sugar content contributes excessively to increase the blood glucose level in the body.
Answer:
roots spread out underground like the branches of a tree as to get sufficient water and nutrients form the soil to transport to the other parts of the tree for its own growth , by spreading out roots tend to collect or suck the maximum nutrients
