vredina [299]

Answer:

B) All DNA molecules will migrate up the gel toward the positive electrode.

Explanation:

Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law  "force of the interaction between the charges is attractive if the charges have opposite signs".

Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).

Xavier drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis.
Elan Coil [88]

Answer:

Is released into the air through stomata

Explanation:

Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.

According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.
