Answer:
Many organisms that undergo chemosynthesis use hydrogen sulphide (H2S) instead of sunlight to fuel the processes that convert carbon dioxide into sugars.
Explanation:
Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.
Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulphide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis. Example, bacteria and methanogenic archaea living in deep sea vents

Explanation:
We will divide the total number of the teachers (246) in the auditorium with the maximum number of seats per row (18) to determine how many rows are completely filled;
246/ 18 = 13.6667
We are only interested in rows that are completely filled which is the whole number;
= 13

It's a pyramid of numbers, I believe.
The HCG hormone is the answer possibly
The answer is nonvascular plants.
The plants that are similar to algae are
called nonvascular plants. They are the plants small plants with the absence of
vascular system. They do not have roots. They have small hair likes that insert
to substrate to keep the plants in place instead of roots. These are called
rhizoids.
