From each of the protein structures listed, the option with the highest level of protein structure as regards with order of amino acids and overall macromolecule structure is quaternary structure. That is option D.
The protein one of the essential nutrients that is found in and consumed by mammals.
There are different types of proteins and their functions depends on their shape, structure or conformation.
The structure of proteins include:
Primary structure: This is the simplest shape of proteins. This is because, the amino acids of a polypeptide is arranged in a linear form.Secondary structure: This is the local folded structures that form within a polypeptide due to interactions between atoms of the backbone.Tertiary structure: These are three dimensional structures of proteins that occurs as a result of the interactions between the R groups of the amino acids that make up the protein.Quaternary structure: This protein structure contains multiple polypeptide chains also called subunits.Therefore, the option with the highest level of protein structure as regards with order of amino acids and overall macromolecule structure is quaternary structure.

A sample of CO2 gas at 100 degrees Celsius has a volume of 250 mL at 760 mm Hg. How many moles of CO2 are present
There are 8.16 × 10-³ moles of CO2 gas at 100°C with a volume of 250 mL at 760 mm Hg.
HOW TO CALCULATE NUMBER OF MOLES:
The number of moles of a sample of gas can be calculated using the following formula:
PV = nRT
Where;
P = pressure of gas (atm)V = volume (L)n = number of moles (mol)R = gas law constant (0.0821 Latm/molK)T = temperature (K)According to this question;
P = 760mmHg = 1 atmT = 100°C = 100 + 273 = 373KV = 250mL = 0.250Ln = ?1 × 0.250 = n × 0.0821 × 373
0.250 = 30.62n
n = 0.250 ÷ 30.62
n = 8.16 × 10-³mol
Therefore, there are 8.16 × 10-³ moles of CO2 gas at 100°C with a volume of 250 mL at 760 mm Hg.

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize these for me ples? Brainliest answer also yes
Answer:
Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.
So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.
Equation: [tex]P_{1} V_{1} = P_{2} V_{2}[/tex]
Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.
So basically Temperature and volume are directly proportional.
Equation: [tex]\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }[/tex]
Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.
Basically, Temperature and Pressure are directly proportional.
Equation: [tex]\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }[/tex]
Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.
Meaning the moles (amount of gas) is directly proportional to volume.
Equation: [tex]\frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} }[/tex] (n stands for moles)
There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.
Answer:
Boyle Law is when pressure and volume have a reverse relationship when temperature is the same.Charles law is basically when volume and temperature have a relationship when the pressure is the same.Lussac Law is I think just when I pressure and temperature is directly tied together when the volume stays the same.I dont think there is any "avogadro law", there is only pressure volume and temperature.

What volume of 0.100 M AgNO3 is
needed to react completely with
45.0 mL of 0.230 M Na2S?
2AgNO3 + Na2S → Ag2S + 2NaNO3
[?] mL AgNO3
Answer:
448mL AgNO3
Explanation:
M x V
n = 0.230 x .045 = 0.01
2AgNO3 + Na2S --> Ag2S+2NaNO3
1 mol Ag2S --> 2 moles AgNO3
.01 mol Ag2S --> ? moles AgNO3
.01x2/1=.02 moles AgNO3
Moles to L conversion is multiplying by 22.4L so we do .02 x 22.4=0.448L

What holds the nucleus together? Group of answer choices alpha particles strong forces electrical forces between the protons beta particles
Answer:electrical forces between the protons
Explanation: The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

A student reads that sodium atoms (Na) react with chlorine (Cl2) molecules to form the compound sodium chloride (NaCl). Which model should the student make to satisfy the Law of Conservation of Matter for the formation of sodium chloride, in simplest form?
Answer:
c
Explanation:
Law of Conservation of Matter for the formation of sodium chloride, in simplest form would be obeyed when 2 moles of sodium react with 1 ,mole of chlorine to form 2 moles of sodium chloride.
What is law of conservation of matter?According to law of conservation of matter, it is evident that matter is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of matter and energy are related as matter has mass and mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of matter is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Explanation:
can y’all please help me answer?
Answer:
It really depends on the situation. If you have 1000 elk and 2 wolves, they really would play a better role in killing off elk so that the elk population doesn't get over populated and diseased, causing a major population collapse. But if there were only 10 elk and 50 wolves, the wolves would play a very negative role on the population.

how do you Calculate the molarity of 250 ml of solution in which 2.7 g of MgCl2 are dissolved
Answer:
Molar mass of MgCl2 is 95 g/mol
Mg = 24 g/mol and Cl = 35.5 ×2 = 71 g/mol
moles = mass given/ molar mass
= 2.7/95 = 0.028 mol
volume = 250/1000 = 0.25 dm3 (ml is the same as dm3)
molarity of MgCl2 = moles/volume
= 0.028/0.25
= 0.112 mol/dm3

d. The animals such as snakes and tortoises are called reptilians. Why?
Answer:
Explanation : Reptiles are cold blooded animals, have scales on their body (instead of hair or fur) and are usually egg laying. (certain viper types and boas give birth to live young). So that is what makes animals reptiles.
Reptiles are cold-blooded creatures that often lay eggs and have scales on their bodies rather than hair or fur. (Some types of vipers and boas give birth to live young).
Due to these reasons animals are reptiles.
What are reptiles?
Air-breathing vertebrates known as reptiles have unique skin consisting of scales, bony plates, or a combination of the two.They comprise of tortoises, turtles, lizards, snakes, and crocodiles.All of them periodically shed their skin's outer covering. The temperature of their environment affects how they function.Reptiles do not maintain a steady internal body temperature, in contrast to birds and mammals. They cannot stay warm on a chilly day without fur or feathers, and they cannot cool themselves on a hot day without sweat glands or the ability to pant. Instead, they shift as needed between the sun and the shade. They stop moving around when the weather becomes colder. Reptiles are cold-blooded due to their slow metabolic rate and heat-seeking habit.
Thus, it can be concluded that animals such as snakes and tortoises are called reptilians.
