The question can refer to the explanation of a specific observation, as in "Why is the sky blue?", but can also be open-ended, as in "How can I design a drug to cure this particular disease?" This stage frequently involves finding and evaluating evidence from previous experiments, personal scientific observations or assertions, and/or the work of other scientists. If the answer is already known, a different question that builds on the previous evidence can be posed. When applying the scientific method to scientific research, determining a good question can be very difficult and affects the final outcome of the investigation.[30]

Select the statements that correctly describe how a new DNA molecule reflects the original DNA molecule from which it was copied
goblinko [34]

Answer:

a. DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original

c. Each new DNA molecule contains an original strand and a newly synthesized strand.

Explanation:

DNA replication is an important process every cell must undergo prior to division. DNA replication is the process whereby DNA content is doubled. It occurs as a result of an enzyme called DNA polymerase, which synthesizes nucleotides.

DNA replication follows the semi-conservative model which uses one original DNA strand to synthesize a new DNA strand. The double-stranded DNA is separated into two single strands which serve as template for new strands. Due to the action of DNA polymerase, DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original.

Also, each newly synthesized DNA molecule which is similar to one another contains an original strand (template) and a newly synthesized strand.

Please help me - fill in the blank
Lorico [155]

In this question, we will understand the air path from entering the nasal passages to reaching the alveoli, where gas exchange takes place.

<h3>What is the air's path to the lungs?</h3>

The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.

a) Blood leaving the air sacs is rich in oxygen gas.

b) When exhaling, the breath is rich in carbon dioxide.

c) If you trace the path of air moving through the respiratory system, it would enter through the mouth and nose. It continues through the pharynx, into the larynx, through the tubes and into the trachea and finally reaches the lungs.
