Large organic molecules are usually assembled by polymerization of a few kinds of simple subunits belonging to the same class of chemicals.  The following is an exception to this statement is:

c) Steroids

Large organic molecules, such as proteins, nucleic acids, and carbohydrates, are typically formed through the process of polymerization. Polymerization involves the repetitive bonding of smaller subunits, known as monomers, to form a long chain or polymer. These monomers usually belong to the same class of chemicals, meaning they have similar structures and functional groups.

In the case of DNA, the monomers are nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The repetitive bonding of nucleotides creates a long chain of DNA.

Similarly, cellulose, a major component of plant cell walls, is composed of repeating units of glucose monomers. The polymerization of glucose molecules forms long cellulose chains.

Contractile proteins, such as actin and myosin found in muscle fibers, are also assembled through the polymerization of monomers. These monomers, called amino acids, are linked together by peptide bonds to form polypeptide chains, which then fold into the functional protein structure.

However, steroids, including molecules like cholesterol, estrogen, and testosterone, are an exception to this general pattern of polymerization. Steroids have a distinct structure consisting of four fused carbon rings. They are not formed through repetitive bonding of identical subunits like proteins or nucleic acids. Instead, steroids are synthesized through specific biosynthetic pathways in living organisms.

While steroids play crucial roles in various physiological processes, they do not follow the typical pattern of polymerization seen in other organic polymers.

Explanation:

It is given that,

The mass of the boy is 20 times that of girl.

Let \(m_b\) and \(m_g\) are the mases of boy and the girls.

A boy and girl are running with the same speed.

The formula for the kinetic energy is given by :

\(E=\dfrac{1}{2}mv^2\)

Where m is mass and v is speed

As speed is same for both boy and girl.

When the child sits on the partially filled balloon, the pressure of the balloon increases. The pressure change is a doubling of the initial pressure, indicating a factor of 2 increase.

When the child sits on a partially filled balloon, the volume of the balloon decreases by half. According to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature, the pressure inside the balloon increases.

Let's consider the initial volume of the balloon as V and the initial pressure as P. When the volume decreases by half, it becomes V/2. Since the amount of gas remains constant, the pressure increases to maintain equilibrium. The new pressure can be denoted as P'.

According to Boyle's Law, P₁V₁ = P₂V₂, where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume. Plugging in the values, we have P * V = P' * (V/2).

Simplifying the equation, we get P' = 2P. This means the pressure of the balloon increases by a factor of 2, or it doubles. So, the pressure change can be expressed as an increase of two times the original pressure.

The three things that are needed for precipitation to form are water vapor, lifting action, and freezing temperatures. When warm moist air is lifted, it cools and condenses into clouds.

If the air continues to cool and the temperature drops below freezing, the water droplets freeze and become ice crystals.

These ice crystals then collide and merge with other ice crystals, forming larger snowflakes or hailstones. Finally, when these snowflakes or hailstones become too heavy to be supported by the updrafts in the cloud, they fall to the ground as precipitation.

Answer:

The most abundant isotope is 1.007 amu.

Explanation:

Given data:

Average atomic mass = 1.008 amu

Mass of first isotope = 1.007 amu

Mass of 2nd isotope = 2.014 amu

Most abundant isotope = ?

Solution:

First of all we will set the fraction for both isotopes

X for the isotopes having mass  2.014 amu

1-x for isotopes having mass 1.007 amu

The average atomic mass is 1.008 amu

we will use the following equation,

2.014x + 1.007  (1-x) = 1.008  

2.014x + 1.007  - 1.007 x = 1.008  

2.014x - 1.007x  =  1.008  -  1.007

1.007 x = 0.001

x= 0.001/ 1.007

x= 0.0009

0.0009 × 100 = 0.09 %

0.09 % is abundance of isotope having mass  2.014 amu because we solve the fraction x.

now we will calculate the abundance of second isotope.

Gases behave ideally when both of the following are true:

(1)The pressure exerted by the gas particles is small compared to the space between them.

(2)The forces between the gas particles are not significant.

According to the kinetic molecular theory, gases consist of tiny particles (molecules or atoms) that are in constant random motion. The behavior of gases can be understood based on the interactions between these particles and their motion. When the pressure exerted by the gas particles is small compared to the space between them, it implies that the gas particles are not densely packed, and there is significant empty space between them. This condition allows the gas particles to move freely and independently without significant interactions or attractions between them.

In an ideal gas, the volume of the gas particles is considered negligible compared to the space between them. This means that the size of the gas particles is small relative to the empty space they occupy. Consequently, the gas particles can be treated as point masses with no volume. Additionally, at low temperatures, the molecules of a gas are not moving as fast as at higher temperatures. This slower motion increases the likelihood of molecular collisions and provides more opportunities for interactions between the gas particles.

On the other hand, when the forces between the gas particles become significant, the behavior of the gas deviates from ideal gas behavior. At high pressures, the number of gas molecules increases, leading to a greater volume occupied by the gas particles. The spacing between the particles becomes smaller, and the interactions between them become more significant. This results in deviations from the ideal gas behavior.

The ideal gas behavior is characterized by small pressures exerted by gas particles compared to the space between them and negligible forces between the gas particles. These conditions allow the gas particles to behave independently and move freely. At low temperatures, the slower motion of gas molecules increases the likelihood of interactions between them. Deviations from ideal gas behavior occur when the forces between the gas particles become significant, typically at high pressures or low temperatures. Understanding these principles helps explain the behavior of gases based on the kinetic molecular theory.

Explanation:

Im assuming the 148.20 is in grams

The equation is Q=mcΔT

Q= Heat (J)

m= Mass

c= SHC (specific heat capacity)

ΔT= Temp change

The most likely temperature of the water after the sphere and the water has reached thermal equilibrium is approximately 70 degrees Celsius. So option C is correct.

This is because heat energy will flow from the metal sphere to the water until they both reach the same temperature. The initial temperature difference between the metal sphere and the water will cause heat to flow from the sphere to the water. As the heat flows, the metal sphere will cool down and the water will heat up. Eventually, they will both reach the same temperature, which will be somewhere between the initial temperatures of the sphere and the water. Therefore option: c is Correct.
