What is polygenic inheritance

Answers

Answer 1
Answer: Polygenetic Inheritance is where many genes can determine one trait, hence the prefix poly.
Answer 2
Answer:

Answer:

Polygenic Inheritance is where one trait (for example, eye color) is determined by multiple genes (two or more).

This typically happens when there is a wide variety of this trait (e.g. height, eye color, hair color, skin color, etc.).

What are the three types of nuclear particles emitted when a radioactive atom decay?

Answers

Answer:

Alpha particles, Beta particles and Gamma rays

Explanation:

The emission of particles when a radioactive atom decays is called radioactivity.

An atom is radioactive as a result of unstable nucleus. This unstable nucleus of the atom disinintegrates and leads to emission of Alpha particles, Beta particles and gamma rays.

Alpha particles contain 2 protons and 2 neutrons. They are positively charged

Beta particles are negatively charged

Gamma rays are electromagnetic waves with short wavelength

Which describes the molecular behavior of a solid? I THINK IT'S A, BUT IM NOT SUREA. Molecules vibrate around a fixed point.
B. Molecules are too far apart to affect each other.
C. Molecules have the greatest energy of motion.
D. Molecules are rigid and do not move.

Answers

I also think it is A
Molecules in a solid should not be able to move. Otherwise it wouldn't be a solid! So the answer is D.

Which of the following substances can be classified as a salt?A.
Sodium Chloride (NaCl)
B.
Vinegar (CH3COOH)
C.
Baking Soda (NaHCO3)
D.
Bleach (NaClO)

Answers

Sodium Chloride (NaCl) can be classified as a salt

Explanation:

Sodium chloride is an "ionic compound" is known as salt. The ratio in which the  sodium(Na) and chloride(Cl) present in sodium chloride in  NaCl is  1:1. It is found in seawater and is accountable for the salinity of the seawater. Also, NaCl is the extracellular fluid for various multicellular organisms.  

When refined, it becomes in its 'edible' form and is used in food preservatives. Whereas, the large quantity of sodium chloride is used in various industries.  

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?

Answers

Answer : The volume of gas will be 29.6 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

(P_1V_1)/(T_1)=(P_2V_2)/(T_2)

where,

P_1 = initial pressure of gas = 12 atm

P_2 = final pressure of gas = 14 atm

V_1 = initial volume of gas = 23 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 200K

T_2 = final temperature of gas = 300K

Now put all the given values in the above equation, we get the final pressure of gas.

(12atm* 23L)/(200K)=(14* V_2)/(300K)

V_2=29.6L

Therefore, the new volume of gas will be 29.6 L

Hello!

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?

We have the following data:

P1 (initial pressure) = 12 atm

V1 (initial volume) = 23 L

T1 (initial temperature) = 200 K

P2 (final pressure) = 14 atm

T2 (final temperature) = 300 K

V2 (final volume) = ? (in L)

Now, we apply the data of the variables above to the General Equation of Gases, let's see:

(P_1*V_1)/(T_1) =(P_2*V_2)/(T_2)

(12*23)/(200) =(14*V_2)/(300)

(276)/(200) =(14\:V_2)/(300)

multiply the means by the extremes

200*14\:V_2 = 276*300

2800\:V_2 = 82800

V_2 = \frac{82800\!\!\!\!\!\!\!\frac{\hspace{0.4cm}}{~}}{2800\!\!\!\!\!\!\!\frac{\hspace{0.4cm}}{~}}

V_2 \approx 29.57142857... \to \boxed{\boxed{V_2 \approx 30\:L}}\:\:\:\:\:\:\bf\blue{\checkmark}

*** Note: the approximation rule says that when the number before the digit 5 ​​is odd, the previous value is raised to the next even number

Answer:

The new volume is approximately 30 Liters
