Amino acids are the fundamental building blocks of proteins. In the cell, amino acid molecules combine to form polypeptide chain or protein.
What are amino acid ?The term amino acids are defined as the building block of the protein. Amino acids are the fundamental building blocks of proteins. Their molecule contains both an amino and a carboxylic group.
Alpha-amino acids are amino acids that have an amino and a carboxyl group attached to the same carbon atom, i.e., an alpha-carbon atom. Glycine, Alanine, etc.
Proteins are made up of monomers called amino acids. A protein is composed of one or more linear chains of amino acids, each of which is referred to as a polypeptide.
Thus, In the cell, amino acid molecules combine to form polypeptide chain or protein.

A laboratory hydrogen generator collects the gas produced by bubbling it through water. The total pressure of the gas collected is 751 mmHg. The temperature is 34 °C, at which water vapor pressure is 40.0 mmHg. Calculate the partial pressure of the hydrogen.
Answer:
[tex]711\ \text{mmHg}[/tex]
Explanation:
[tex]P_{total}[/tex] = Total pressure = 751 mmHg
[tex]P_{water}[/tex] = Vapor pressure = 40 mmHg
[tex]P_{gas}[/tex] = Pressure of gas
The total pressure in a system is given by Dalton's law
[tex]P_{total}=P_{gas}+P_{water}\\\Rightarrow P_{gas}=P_{total}-P_{water}\\\Rightarrow P_{gas}=751-40\\\Rightarrow P_{gas}=711\ \text{mmHg}[/tex]
The partial pressure of the hydrogen is [tex]711\ \text{mmHg}[/tex]

The particles in liquids and gases show random motion. What does that mean and why does it occur??
Answer:
Liquids and gases show random movements because of potential and kinetic energy.
It happens when heat is applied to the particles and they gain more potential and kinetic energy and move around faster. With gases, they have the most energy.
If anything doesnt make sense, make sure to message me
Answer:
The particles show random motion because liquid and gas particles do not have a rigid structure, unlike solid particles. They are free to go anywhere.

12) A 17.92 g sample of copper was submerged in water, and the volume reading rose by 2.00 mL. What is the density of the copper sample?
Hey there!:
Mass = 17.92 g
Volume = 2.00 mL
Density = ??
Therefore:
D = m / V
D = 17.92 / 2.00
D = 8.96 g/mL
Hope this helps!
The density of an object is obtained as the ratio of mass of an object to its volume.
In science, density is defined as mass per unit volume. The volume of an object is the same as the volume of water displaced by the object.
Since the volume of water rose by 2.00 mL, then the volume of copper is 2.00 mL.
The density is now; mass/volume
Mass = 17.92 g
Density = 17.92 g/2.00 mL
= 8.96 g/ml

State the law of conservation of mass in mathematical terms.
Answer:
The law of conservation of mass states that no atoms are lost or made in a chemical reaction. Instead, the atoms join together in different ways to form products . This is why, in a balanced symbol equation, the number of atoms of each element is the same on both sides of the equation.

How do scientist respond to experimental observations that don’t match current theories?
Answer: The results of the experimental observations should coincide with the facts of the current theories.
Explanation:
The scientific theory can be defined as the well defined as supported explanation for a natural phenomena. It is based upon the facts observed and also supported by the evidences obtained from the experimental trials.
If the experimental observations do not match with the concept of current scientific theory then the scientific either perform the experiment with the same scientific methodology or can switch to another scientific methodology to satisfy the facts of the current theories.
Transpiration is C. The evaporation of water out of the stomata of plants B. The absorption of water through the roots D. The evaportation of water out of the roots A. Simple diffusion
Answer: Option C.
The evaporation of water out of the stomata of plants
Explanation:
The evaporation of water out of the stomata of plants is transpiration because transpiration is the evaporation or loss of water inform of vapor from the stomata of leaves or flowers. Water is first absorbed by the root and it is moved to plant parts including leaves by xylem vessels since the roots already retained which it can use and when the water get to the leaves, it is loss inform of water vapor.
I need help with figuring out how to calculate the frequency of light, because my teacher's notes are generic. When I asked her about it on top of another question; she only answer that other question" and never talked about the notes.
Answer:
See explanation
Explanation:
The general formula used to obtain the frequency of a wave is;
v=λf
where;
v = speed of the wave
λ= wavelength of the wave
f= frequency of the wave.
Now, the speed and wavelength of light in various media are known.
If we plug the value of the speed of light and the wavelength of light into the formula given above, we can obtain the frequency of light.
The frequency of a photon of light can also be obtained from Plank's equation;
E= hf
where;
E =energy of the photon of light
h = Plank's constant
f= frequency of the photon.
This is used when the energy of the photon of light is supplied or can be calculated using the wavelength of light provided in the problem.
