Following are the answers related to traits of genes.
How do genotypes work?
Gene pool as a whole is characterized by the term "genotype," which roughly refers to an organism's genetic make-up. The term can also be used in a more precise sense to refer to the several alleles, or variations of a gene, that an organism possesses.
Describe the phenotype.A person can be recognized by their phenotypes, which include things like height, eye color, and blood type. A person's phenotype is influenced by both their genotype (genotype) and environment.
A dominating attribute is what?refers to a trait that develops more frequently than another trait due to interactions between gene alleles.
A recessive characteristic is what?a trait that is only present in homozygous genotypes; a trait that is frequently concealed by other inherited characteristics but persists in a population of heterozygous genotypes.

what volume (ml) of 0.0755 m phosphoric acid can be neutralized with 130 ml of 0.245 m sodium hydroxide? what volume (ml) of 0.0755 m phosphoric acid can be neutralized with 130 ml of 0.245 m sodium hydroxide? 2340 141 1270 422 7.21
146 mL of 0.0755 m phosphoric acid can be neutralized with 130 ml of 0.245 m sodium hydroxide.
First of all, let's write a balanced equation.
The balanced equation is given below.
H₃PO₄ + 3 NaOH ⇒ Na₃PO₄ + 3 H₂O
Now calculate the moles of sodium hydroxide taking part in the reaction.
130 ml of 0.245 m sodium hydroxide react.
0.13 L x 0.245/L = 0.03185 moles
Now let's calculate the reacting moles of H₃PO₄.
The molar ratio of H₃PO₄ to NaOH is 1:3.
The reacting moles of H₃PO₄ are 1/3 x 0.03185 moles = 0.011 moles
Let's calculate the reacting volume of phosphoric acid
We have 0.011 moles of H₃PO₄ are in a 0.0755 M solution.

how many grams (g) of nacl are needed to make a 125 ml of 0.45m nacl solution? answering this question requires 3 steps.
Answer:
3.29 grams NaCl
Explanation:
I assume 0.45m is 0.45 molar. The m is usually capitalized, to prevent confusion with meters, moles, etc. : 0.45M
It is very useful to use of the definition of molar in the thought process.
The definition of molar, M, is moles solute per liter of solution. The term 0.45M NaCl means that a solution has 0.45 moles of NaCl in 1 liter of solution. a half-liter would have 0.225 moles of NaCl, which is equivalent to 0.45 moles/liter. in terms of concentration.
We'll need the molar mass of NaCl, which is:
Na: 23.0
Cl: 35.5
58.5 grams/mole
========
Now let's calculate how many moles of NaCl are needed. We want 125ml (0.125L) of 0.45M NaCl.
(0.45 moles NaCl/Liter)
multiply that by the actual volume required:
(0.45 moles NaCl/Liter)*(0.125Liter) = 0.0563 moles NaCl
[The liters unit cancels, leaving only moles NaCl. The units are helpful in understanding the mathematical steps required and help insure a correct answer.]
To get grams NaCl, multiply by the molar mass of NaCl:
(0.0563 moles NaCl)*(58.5 grams NaCl/mole NaCl) = 3.29 grams NaCl
Note the units: moles NaCl cancel, leaving grams NaCl.
=====
There is a useful relationship to remember concerning the dilution of a solution. It is not needed here, but it does highlight the usefulness of understanding units. When diluting a volume, V1, of a solution of concentration M1 to achieve a concentration and volume of of M2 and V2, we can use:
M1V1 = M2V2
Example: 125 ml of 1M HCl is needed for an experiment. The only supply is 5M HCl. How much of the 5M HCl is needed to make 125ml of the 1M HCl?
M1 = 5M HCl
V1 = The unknown
M2 = 2.5M HCl
V2 = 100 ml
M1V1 = M2V2
(5M)*(V1) = (1M)*(125ml)
V1 = (1M)*(125ml)/(5M)
V1 = 25 ml
25 ml of 5M HCl may be added to 75 ml of water (slowly) to form 100ml of 2.5M HCl.
===========
Extra material: This is not relevant to the original problem, but it demonstrates the importance of units and the fact that it is the moles of a substance that is the important element.
If the concentration and volume of M1V1 are in moles/liter and liter, the term M1V1 has units of:
(moles/Liter)*(L), which reduces to moles of the substance.
The same with the term on the right, M2V2: it also reduces to moles. So the equation is simply saying that whatever number of moles one starts with, the same number of moles will wind up in the final solution.
A bonus discovery is that the volume units cancel in this calculation. It seems unlikely, but this means the volumes don't need to be adjusted from ml to liters, since volume unit cancels out.
If the original problems stated that the goal is to make 125 ml of 0.45M NaCl from a stock of 1.0M NaCl solution, the calculation would be:
M1 = 1.0M NaCl
V1 = ?
M2 = 0.45M NaCl
V2 = 125 ml
M1V1 = M2V2
(1.0M)*(V1) = (0.45M)*(125ml)
V1 = 56.25 ml
68.75 ml of water may be added to 56.25 ml of NaCl to form 125 ml of 0.45M NaCl.
Although M is expressed as moles/liter, we don't need to convert the volumes to liters, because the M unit cancels out. That doesn't feel correct, but it is - the unit cancellation is legal.

ہے
In the summer, the Moxie's tank will be under 110.5 atm of pressure.
The right answer is C.
What is the law of pressure?The pressure law states that for a given quantity of gas, provided the volume stays constant, the pressure exerted on the container's sidewalls is exactly proportional to the absolute temperature of the gas.
Briefing: The mathematical formulation of this rule is
[tex]\frac{P_1}{T_1 }= \frac{P_2}{T_2}[/tex]
where
The initial pressure is P1.
P2 is the ultimate pressure.
T1 is the initial temperature.
T2 is the final temperature.
As the gas's temperature rises, so does its pressure.
The pressure within the Moxie's tank will thus be greater than 50 atm throughout the summer since summer temperatures are higher than winter ones.

When is mass not conserved?
Mass is not conserved when the chemical reaction occurs inside the body.
What violates the conservation of mass?Mass is converted into energy when reactions within the mass occur. Nuclear reactions violate the law of conservation of mass. No new atoms are created during the reaction and no existing atoms disappear or are destroyed showing that mass is conserved. Mass can not be conserved because a little amount of mass turns into energy in every chemical reaction. But mass + energy is always conserved. Energy can only be created by destroying the specific amount of mass according to the equation of energy i.e. E = mc².

mass of S8 :
Mass of S₈ is 130 grams
Mass is a measure of the amount of matter that an object contains
Here given data is 94.0 g of each reactant and we have to find mass of S₈= ?
Here the reaction are given
8SO₂+16H₂S → 3S₈+16H₂O
So, 3 moles S₈ will be produced from 8 moles SO₂ and 16 moles H₂S and now determine how many moles of SO₂ and H₂S are actually present during this reaction and that will allow us to then calculate the maximum mass of S₈ that can be produced
For SO₂ = 94.0 grams/(64.1 g/mole) =1.44 moles SO₂
For H₂S = 94.0g H₂S (34.1 g/mole) = 2.70 moles H₂S
2.70 moles H₂S(3 moles S₈/18 moles H₂S) = 0.506 moles of S₈
The molar mass of S₈ is 257 g/mole.
