Answer:
The correct option is B.
Codorminance.
Explanation:
The type of inheritance pattern is codorminance because in codorminance the two alleles in the gene are expressed, no allele was able to masked the express on the other allele. The chestnut colored horse allele is expressed likewise the white
colored allele too is expressed none of the two alleles mask the Expression of the other, the two are expressed to give offsprings roan colored which is an indication of the two expression.

50 POINTS! I really need help with these pressure and volume questions from Boyle's Law. PLEASE HELP
1.If a sample of gas has a volume of 100.0ml when the pressure is 50.0kPa, what is the volume when the pressure is increased to 400.0kPa, assuming temperature and number of moles is held constant?
2. What pressure would be required to take 100.0ml of a gas at 103.0kPa and squish it down to 2.00ml, assuming temperature and number of moles is held constant?
4. If the temperature and number of moles are held constant, what would be the new volume if 2.00cm3 of a gas at 3.00atm is changed to 0.0200atm?
7. What pressure must be applied to a sample of Freon gas having a volume of 325L at 20.0°C and 723Torr to permit the expansion of the gas to a volume of 975L at 20.0°C?
Answer:
1) [tex]V_{1}[/tex]= 100ml = 0.1 L
2) [tex]P_{1}[/tex]= 50kPa
[tex]1) P_{2} =400 kPa\\2)V_{2} =?[/tex]
So,
[tex]P_{1}V_{1} = P_{2} V_{2}[/tex]
[tex]V_{2} = \frac{0.1 x 50}{400}[/tex]
[tex]V_{2} = 0.0125 L[/tex]
[tex]2) V_{1} = 100 mL = 0.1 L\\P_{1}= 103 kPa\\V_{2}=2 mL\\P_{2} =?\\[/tex]
[tex]P_{1} V_{1} =P_{2} V_{2}\\ P_{2}=\frac{0.1x103}{2}\\ P_{2}=5.15 kPa[/tex]
[tex]4) V_{1}=2 cm^{3} = 0.002 dm^3\\P_{1} =3 atm x 760 = 2280 torr\\P_{2} = 0.0200 atm x 760=15.2 torr[/tex]
Same, formula as above,
[tex]V_{2}=\frac{2280x0.002}{15.2}\\V_{2}=0.3 L[/tex]
[tex]7)V_{1}=325\\T_{1}=20^{0}C=293K\\ P_{1}=723 torr\\V_{2}=975L\\T_{2} = 20^0 C= 293K\\P_{2}=?[/tex]
By the formula,
[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}} \\P_{2} = \frac{723x325x293}{293x975}[/tex]
[tex]P_{2} =241 Torr[/tex]

Question 1 (2 points)
(05.03 LC)
Which of the following is one part of a chemical formula? (2 points)
оа
A number that shows the total atomic mass of the substance
Ob
The full name of each element shown
ос
The symbol of each element in the substance
Od
A number that shows the total number of chemical bonds
Answer:
C. The symbol of each element in the substance
Explanation:
The chemical formula of a compound is a representation which shows the elements therein and the mole relationship between them expressed as subscripts.
A chemical formula is made up of chemical symbols and the mole relationships. For example, HCl represents 1 mole of hydrogen chloride molecules with each consisting of 1mole of hydrogen atoms and 1 mole of chlorine atoms.If a substance has a density of 2.7g/cm3 and a mass of 86.4g, what is its volume?
Answer:
32cm³
Explanation:
Given parameters:
Density of substance = 2.7g/cm³
Mass of substance = 86.4g
Unknown:
Volume of substance = ?
Solution:
Density is the mass per unit volume of a substance.
Density = [tex]\frac{mass}{volume}[/tex]
Since the unknown is volume we solve for it;
mass = density x volume
86.4 = 2.7 x volume
volume = [tex]\frac{86.4}{2.7}[/tex] = 32cm³

Biomes on Earth have exhibited changes throughout history that have been caused by a variety of factors. Over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation. What factor is likely most responsible for the changes observed in the world's rainforests? a. volcanic activity b. human activity c. temperature changes d. solar eclipses Please select the best answer from the choices provided A B C D
Answer:
b
Explanation:
The factor that is most likely to be responsible for the changes observed in the world's rainforest is human activities.
There has been a surge in the human population leading to an increased need for housing, foods, and other infrastructures. All these needs are directly or indirectly provided by the forest. Hence, the more the population of human expands, the more pressure that would be exerted on the rainforest and, indeed, other forests of the world.
The correct option is b.

An object weighs 530.0 Newton. It is being pushed along a horizontal surface by a 340.0-
Newton force. Determine the mass of the object. Enter a numerical answer.
Answer:
54.08 kg
Explanation:
The weight of an object is the force of gravity acting on the object and is related to the mass of the object as;
Weight = mass x acceleration due to gravity (g), where g = 9.8 m/s.
Hence, the weight of the object is only dependent on its mass and g, not on any other force. Now, if the weight is 530.0 N,
530 = m x 9.8
m = 530/9.8
= 54.08 kg
Therefore, the weight of the object is 54.08 kg.
23. A ball is dropped from 215m. How long will it take to reach the ground?
Answer:
6.6 s.
Explanation:
From the question given above, the following data were obtained:
Height (h) = 215 m
Time (t) =..?
Thus, we can obtain the time taken for the ball to get to the ground by applying the following formula:
h = ½gt²
Where:
h is the height.
g is the acceleration due to gravity
t is the time to taken.
With the above formula, the time taken for the ball to get to the ground can be obtained as follow:
Height (h) = 215 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =..?
h = ½gt²
215 = ½ × 9.8 × t²
215 = 4.9 × t²
Divide both side by 4.9
215 / 4.9 = t²
Take the square root of both side.
t = √(215 / 4.9)
t = 6.6 s
Therefore, it will take 6.6 s for the ball to get to the ground.

6. Potential energy that depends on height is called *
O kinetic energy
O gravitational potential energy.
elastic potential energy.
O mechanical energy
The potential energy that depends on height is called gravitational potential energy. (Option B)
What is gravitational potential energy?Gravitational potential energy is a form of potential energy that an object possesses due to its position relative to a gravitational field.
When an object is raised to a certain height above the ground, it gains gravitational potential energy. The higher the object is raised, the greater its potential energy.
This potential energy is a measure of the work that would be required to move the object against gravity and bring it back down to its original position.
The formula for gravitational potential energy is;
Potential Energy (PE) = mg h

PE is the gravitational potential energym is the mass of the objectg is the acceleration due to gravityh is the height or elevation of the objectLearn more about gravitational potential energy here: https://brainly.com/question/15896499

Atomic theory describes the motion of particles in solids, liquids, and gases. Which statement best describes the particles in a given state of matter?
A. The particles in gases have a fixed position but can vibrate.
B. The particles in solids have a fixed position but can vibrate.
C. The particles in solids are very close to each other but they are able to move past each other. D. The particles in gases are very close to each other but they are able to move past each other.
Answer:
B. The particles in solids have a fixed position but can vibrate
Explanation:
Answer choice "A" is incorrect because particles in gases are not held by bonds and move freely (not fixed).
Answer choice "C" is incorrect because while solids are close in proximity, their particles do not move past each other.
Answer choice "D" is incorrect because while the particles in gases are able to move past each other, they are not arranged in close proximity. In fact, them being spread out and free is why they are able to move past each other.

3. Mount Everest, an eastern Himalayan peak on the Tibet-Nepal border, was discovered to be the world's highest mountain in March 1856. The Survey Department of the Government of India computed its height to be 29,002 ft. Express this height in scientific notation.
Answer:
h = 2,9002 10⁴ ft
Explanation:
Scientific notation is a method to write very large and small numbers clearly, the figure is written with an integer and the other figures in decimals, with an exponent so that the number does not change.
If it is necessary to approximate a figure, the criterion is if the next figure is greater than or equal to five, the figure rises by one unit.
Mount Everest height
h = 29002 ft
h = 2,9002 10⁴ ft
if we approximate three significant figures that
h = 2.90 10⁴ ft
Answer:
[tex]2.9002 \cdot 10^{4} ft[/tex]
Explanation:
To express the height 29,002 in scientific notation we need to move the decimal point four places to the left and express the answer into a base-ten power, as follows:
[tex]29,002 = 2.9002 \cdot 10^{4}[/tex]
The answer expressed in scientific notation results in 2.9002 times a ten to the fourth power, as a result of the four movements of the decimal point.
I hope it helps you!
