Answer:
Empirical: OH
Molecular: 
Explanation:
First of all, we are going to use the formula: mass = no. moles x Molar Mass And rearrange it to find No. moles: No. moles = mass/Molar Mass
Let's start with Hydrogen:
The given mass is 0.44g, and hydrogen's molar mass is 1.01, therefore the number of moles is: 0.44/1.01 = 0.4356
Now we do the same for Oxygen:
Given mass = 6.92, Molar mass of Oxygen = 16.00, No. Moles = 6.92/16.00 = 0.4325
Now we identify the smaller one (Oxygen as 0.4325 < 0.4356) and we divide both values by that number:
0.4325/0.4325 = 1
0.4356/0.4325 = 1.01
We round both to the nearest 0.2 or 0.25 (depending on what you're taught), and we get: 1 and 1.
This means that the empirical formula has one of each: OH
Now to find the molecular formula we find the relative mass of OH and divide the given mass by that:
M(OH) = 16.00+1.01 = 17.01
34.00/17.01 = 2
We now multiply both by this number to get:

The C horizon is the answer.
The main component of cell walls is cellulose. The cellulose make stems, leaves and branches. So it play an important role in building of tissues. ... The molecules of cellulose have hydroxyl group that form hydrogen bonding with other cellulose and provide support to plant.
Calcitonin <u>suppress </u>osteoclast activity, which will <u>lowers</u> blood calcium levels.
<h3>What is Calcitonin?</h3>
- Calcitonin is a hormone secreted by thyroid gland.
- Calcitonin reduces the concentration of blood calcium level when it is above normal level.
- This polypetide hormone is made up of 32 amino acid and is mainly produced by C cells of the thyroid gland.
- In fish, birds and other non-mammalian animals, Calcitonin is produced by cells of the ultimobranchial body.
