Answer:
<h2>
Gram staining is a technique used to differentiate between Gram-positive and Gram-negative bacteria.</h2>
Explanation:
Gram stain color the bacteria either red or violet depending on whether they are Gram positive or Gram negative. Gram positive bacteria have thick cell wall containing peptidoglycan compared to Gram negative bacteria which have thin cell wall. Due to this Gram positive bacteria stains purple by crystal violet. So, slide containing <em>S. pyogenes</em> with purple violet indicates that it is a Gram positive bacteria.
Answer:
C. Plants must be able to increase their mass using substances in addition to what is found in soil
Explanation:
The plant increased its mass by 74.4 kg, and the mass of the soil decreased only by 54 g (less than 0.1 % the mass of the plant).
The plant must have gotten its mass from someplace other than the soil.
A is wrong. The plant gets its mass from someplace else.
B is wrong. Plants don't need soil as such, but they need the water that is in the soil.
D is wrong. The water contains no food. It is just water.
E is wrong. The experiment demonstrated nothing about oxygen.
