To solve this we must be knowing each and every concept related to mutation and types of mutations. Therefore, the correct option is option C.
What is mutation?A mutation is, at its most basic, a change or alteration. Chromosome and gene alterations, known as mutations in biology, frequently appear physically.
One grizzly bear population has moved to an area that has snow year-round. If a mutation for coat color is going to spread through the population then Grizzly bears that have a lighter fur mutation can catch prey more easily and so have more resources to have more offspring. Due to this, the trait starts to spread through the population.
Therefore, the correct option is option C.

What happens to molecules when they move faster?
When molecules move faster, they increase their kinetic energy.
What is Kinetic energy?
Kinetic energy is essentially the energy of motion. It is the type of energy that an object possesses as a result of its motion. It is commonly defined as the work required to accelerate a given mass body from rest to its stated velocity. Kinetic energy is directly related to the object's mass and the square of its velocity.
This increase in kinetic energy causes the molecules to vibrate more rapidly, resulting in an increase in temperature. As molecules move faster, they also collide with each other more frequently, leading to more chemical reactions.

 (Question) How many atoms are in 3 grams of Cu?
(20 points)
3 grams of Cu = 6.022 x 10^23 atoms of copper.
Answer:
2.84 × 10^22 atoms
Explanation:
To calculate the number of atoms in 3 grams of Cu, we can use avogadro's constant where:
[tex]1 \: mole = 6.02 \times 10 {}^{23} \: atoms[/tex]
Firstly, we have to calculate the number of moles in 3 grams of Cu. The formula to calculate moles is:
[tex]moles = \frac{mass}{molar \: mass} [/tex]
the mass = 3g and the molar mass = 63.55 (this value can be found in the periodic table)
Substitute the values in formula:
[tex]moles = \frac{3}{63.55} [/tex]
[tex]moles = 0.0472[/tex]
Now use the number of moles to convert to atoms using avogadro's number, where x is the unknown number of atoms we want to find:
[tex]1 \: mole : 6.02 \times 10 {}^{23} \: atoms[/tex]
[tex]0.0472 \: moles : x \: atoms[/tex]
Cross multiply and equate to solve for x:
[tex]1 \times x = 6.02 \times 10 {}^{23} \times 0.0472[/tex]
[tex]x = 6.02 \times 10 {}^{23} \times 0.0472[/tex]
[tex]x = 2.84 \times 10 {}^{22} \: rounded \: to \: 3sf[/tex]
Hence, there are 2.84 × 10^22 atoms in 3 grams of Cu

What is the first thing you should do following an accident with a chemical?
Immediately rinse chemicals off with a lot of water.
Different assistance must be used because different chemical accidents might occur in various ways.
Help while inhaling a chemical:To provide the person access to fresh air, remove them from the factory or work location. Make sure your company has a plan in place for what to do if a worker becomes unconscious or is unable to move. If the person has inhaled chemicals, administer oxygen from an oxygen tank.
Help if a Chemical touch your skin:Immediately rinse chemicals off with lots of water for at least 15 minutes. The more quickly and for a longer period of time you start to pour water over the region, the more damage you will limit. Chemicals that catch fire or absorb quickly through the skin must be washed for a longer time, 30 minutes to 1 hour.
Help if chemical is in eye:Right away, rinse the eye or both eyes. Rinse for at least 15 minutes while using a lot of water. If you have an emergency eye wash, activate it while keeping your eyes open with your fingers. If you must use your hands to splash water in your eyes, keep them open while doing so. Seek assistance in keeping them open.
Help if chemical is in mouth:Look for the chemical label or any other relevant information. Typically, the label will provide information on "ingestion" in the first aid section. If the person should vomit up the chemical or not is determined there. It is crucial that you heed that counsel. If the chemical is consumed, the label can include an antidote.

Estimate how much heat in joules is released when 25. 0 g of water (C = 4. 184 J/g°C) is cooled from 80. 0°C to 30. 0°C?
The heat in joules is released when 25. 0 g of water (C = 4. 184 J/g°C) is cooled from 80. 0°C to 30. 0°C is -5210 J
To find the amount of heat released when a substance is cooled, we can use the equation:
q = mcΔT
where q is the amount of heat (in joules), m is the mass of the substance (in grams), c is the specific heat capacity of the substance (in joules per gram per degree Celsius), and ΔT is the change in temperature (in degrees Celsius).
Given the information in the question, we have:
m = 25.0 g
c = 4.184 J/g°C
ΔT = 30.0°C - 80.0°C = -50.0°C
So, we can substitute these values into the equation and get:
q = (25.0 g)(4.184 J/g°C)(-50.0°C)
q = -5210 J
Therefore, the amount of heat released when 25.0 g of water is cooled from 80.0°C to 30.0°C is -5210 J.
A negative sign means the heat is absorbed during the cooling process, it is an endothermic process.

The percent composition of vanadium in the ore is 1A: 10.8%, and the percent composition of lead is 2B: 73.2%.
Vanadinite (Pb₅ (VO₄)₃Cl) = 1250 grams
Pure vanadium= 135 grams
Pure lead = 915 grams
Percent composition of vanadium =?
Percent composition of lead =?
The formula to find the percent composition is as follows:
Percent composition =(substance mass in grams/ sample mass in grams) × 100
1: Now solving to find the percent composition of vanadium by putting values in the formula:
Percent composition of vanadium = (vanadium mass/sample mass) × 100
Percent composition of vanadium = (135 g/ 1250 g) × 100
Percent composition of vanadium = 10.8 %
2: Now finding the percent composition of lead by using the same formula:

What are the things to consider before using hot and cold compress?
Answer:
Explanation:
There are several things to consider before using hot and cold compresses:
The condition being treated: Different conditions may require the use of hot or cold compresses. For example, hot compresses may be used to alleviate muscle pain, while cold compresses may be used to reduce swelling and inflammation.
The individual's sensitivity to temperature: Some people may be more sensitive to temperature changes and may need to use a compress that is not as hot or cold.
The duration of use: It is generally recommended to use hot compresses for no more than 20 minutes at a time, and cold compresses for no more than 15 minutes.
The potential for burns or frostbite: Hot compresses should not be used on skin that is broken or damaged, as they can cause burns. Cold compresses should not be applied directly to the skin for an extended period of time, as they can cause frostbite.
The individual's overall health: Individuals with certain medical conditions, such as circulation problems, should be careful when using hot and cold compresses and should consult with a healthcare professional before doing so.

Frida wants to find the volume of a stone by measuring the change in water volume before and after the stone is added. She fills a measuring cup with 473 mL of water and drops the stone in, causing the water level to rise to 499 mL. Using the conversion factor that 1 mL = 1 cm³, the initial volume of water is 473 cm³ and the final volume of water is 499 cm³. By applying the equation [Volume of stone] + [Initial water volume] = [Final water volume],
substituting the values

if the density of hydrogen is 0.090 g l and its rate of diffusion is 5.93 times that of chlorine, what is the density of chlorine
The density of chlorine will be 3.163 g/L.
The mass of a substance per unit of volume is its density. According to Graham's law, a gas's rate of effusion is inversely proportional to its square root density. When a material's particles are concentrated in a low area, they tend to travel to the place where the concentration is highest. When we use perfume or a scented spray in one area of the room and subsequently can smell it throughout the entire space, that is a simple illustration of this process.
rate1 = H2 = 5.93
rate2 = Cl2 = 1
The molecular weight of H2 = 2.016
The molecular weight of Cl2 = x.
By Graham's Law:
5.93 / 1 = x / 2.016
35.1649 = x / 2.016
