Answer:
The correct answer is D.
Explanation:
Amino acids can be classified <u>depending on the side chain structure</u> in
- acidic
- basic
- neutral
- aliphatic
- aromatic
- sulfur containing amino acids.
Aspargine is a <em>neutral amino acid</em> that has a key role in <u>glycoproteins biosynthesis.</u> Aspargine helps the body to resist fatigue and contributes to a smooth functioning of the liver.
Answer:
P₂ = 3.19 atm
Explanation:
Given data:
Initial volume = 700 mL
Initial pressure = 1 atm
Initial temperature = 273K
Final temperature =100°C (100+273= 373 K)
Final volume = 300 mL
Final pressure = ?
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm × 700 mL × 373K / 273 K ×300 mL
P₂ = 261100 atm .mL. K /81900 K .mL
P₂ = 3.19 atm
Here are three everyday situations which it would be useful to identify unknown substances:
1. When you have two clear substances with no labels yet you are not sure which substance is water and which one is not and not knowing what this unknown chemical might do.
2. A stain on your clothes
3. When you are not feeling well and your sense of taste is not functioning well.
The ways that these can be identified is first, start by the appearance, for example the state, color, texture, etc. And secondly, use your sense of smell. This sense is also helpful in identifying whether the substance is something strong or not.
So we have: 1 C2H5OH + _ O2 -> 2 CO2 + _ H2O Step 3: The only molecule on the right that is left is H2O. We start with 6 hydrogen atoms<span> on the left.</span>
The model of photosynthesis used by biologists begins when chlorophyll splits a water molecule into hydrogen and oxygen. The oxygen from the water is a waste product that is released as a gas. In later stages of photosynthesis, carbon dioxide from the air and hydrogen from the water unite to form glucose. Photosynthesis usually takes place in the leaves of green plants. The food produced is a simple sugar called glucose. Some of the food made during photosynthesis is used by plants for their growth and development. The rest is stored in the plant.
