When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it w

as because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? Ask his mother to make the plant better. Wait and see what happens to the plant. Remove the plant from direct sunlight after a week. Ask his science teacher at school what she thinks could be the reason.

Answer:

Wait and see what happens to the plant.

Explanation:

<em>The best course of action for Jeremy would be to wait and see what happens to the plant after moving it closer to the window to get more sunglight.</em>

If the plant grows after observing it for some times, he can conclude that light has been a major hindrance to the growth and more sunlight would benefit the plant. If the observation is otherwise, then Jeremy can conclude that the lack of growth observed is not due to light.

(C6H6) can be biodegraded by microorganism. if 30 mg of benzene is present, what amount of oxygen required for biodegradation, n
quester [9]

Answer:

36.92 mg of oxygen required for bio-degradation.

Explanation:

5C_6H_6+15O_2\rightarrow 12CO_2+15H_2O

Mass of benzene = 30 mg = 0.03 g (1000 mg = 1 g )

Moles benzene =\frac{0.03 g}{78 g/mol}=0.0003846 mol

According to reaction 5 moles of benzene reacts with 15 moles of oxygen gas.

Then 0.0003846 mol of benzene will react with:

\frac{15}{5}\times 0.0003846 mol=0.0011538 mol of oxygen gas

Mass of 0.0011538 moles of oxygen gas:

0.0011538 mol × 32 g/mol = 0.03692 g = 36.92 mg

36.92 mg of oxygen required for bio-degradation.

The solubility of KNO3(s) in water increases as the..
makvit [3.9K]
The answer would be b. Temperature of the solution increases 

Temperature determines the kinetic energy of the water molecule. Higher temperature will cause the molecule to moves faster and the compound (KNO3) could break solute molecule easier make it become more soluble. A higher pressure will increase the solubility of a gas, not solid

Can you u eat mold??????? ​
Dahasolnce [82]

Answer:

You should avoid moldy foods as much as possible

Explanation:

Mold might produce harmful mycotoxins in all types of foods, but mycotoxin levels are tightly regulated. That said, you should avoid moldy foods as much as possible, especially if you have a respiratory allergy to mold. Nevertheless, accidentally ingesting it will probably not cause any harm.

How do the major and minor scale divisions relate the precision of measurements taken with a metric ruler or graduated cylinder?
Nata [24]

Answer: Major scale and minor scale both relate the precision of measurements with more true value of measurement.

Explanation:

Major scale in a measuring device is maximum unit value on the scale that can be measured.

Minor scale in a measuring device is a least unit value on the scale that can be measured.

In a metric ruler major scale is 1 cm and minor scale is 0.1 mm which means one can measure accurate value up-to one decimal point and in 10 ml of graduated cylinder major scale division is 1 ml minor scale division is 0.01.
