Answer:
D) An original parent DNA strand and one newly synthesized DNA strand comprising a new DNA molecule.
Explanation:
- Semi-conservative replication refers to two strands of DNA unzip, and a new strand is assembled onto each 'conserved' strand.
- The replicated double helix consists of one old strand and one newly synthesised strand.
- It describes the structure of DNA, a twisted helix of two strands with bases joining the strands.
Answer: there is no permanent charge difference between one part of the molecule and another.

Iodine
A diffuse, nontoxic goiter is usually due to a lack of Iodine in the diet.
Explanation;
-A diffuse non-toxic goiter is an enlargement of the thyroid gland without nodularity. It occurs in an endemic and sporadic distribution. It does not result from an inflammatory or neoplastic process and is not associated with abnormal thyroid function.
-Simple nontoxic goiter, which may be diffuse or nodular, is noncancerous hypertrophy of the thyroid without hyperthyroidism, hypothyroidism, or inflammation. Except in severe iodine deficiency, thyroid function is normal and patients are asymptomatic except for an obviously enlarged, non tender thyroid.
Answer:
Diagram 1
Explanation:
The correct diagram that depicts the liquid layers in the cylinder would be diagram 1.
<u>The density of a substance is a measure of how heavy the substance is. Hence, a liquid that is heavier than water (with higher density) would sink in water while a liquid that is less dense than water would float on it. </u>
<em>Therefore, based on the density of the karo syrup (1.4 g/mL), it would take the bottom space in a cylinder, followed by water (1.0 g/mL) while vegetable oil with 0.91 g/mL would float on the former two. </em>
The correct diagram is 1.
