Answer:

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

zvonat [6]

Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.

1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.

1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.

3:1 is the phenotypic ratio for complete dominance.

2:1 is the phenotypic ratio for lethal recessive.

Anxiety and guilt

Ritualistic behavior seen in this disorder is aimed at controlling feelings of anxiety and guilt by maintaining an absolute set pattern of action. Although the person with an obsessive-compulsive disorder may be angry and hostile, the feelings of anger and hostility do not precipitate the rituals. Although the person with an obsessive-compulsive disorder may be embarrassed and ashamed by the ritual or feel hopeless and powerless to the ritual, the basic feelings precipitating the rituals are usually anxiety and guilt.

How many grams of urea (non volatile, non electrolyte) must be added to 1250. g water to give a solution with a vapor pressure l

Lady bird [3.3K]

Answer:

$\large\boxed{\large\boxed{107g}}$

Explanation:

The vapor pressure lowering is a colligative property and it follows Raoult's law.

The vapor pressure lowering of a solvent in a solution, ΔP, is equal to the mole fraction of the solute, Xsolute, multiplied by the vapor pressure of the pure solvent, P°.

$\Delta P=X_{solute}\times P^0$

ΔP and P⁰ are given:

ΔP = 1.39mmHg

P⁰ = 55.32mmHg

1. Mole fraction of solute

Thus, you can calculate Xsolute:

$1.39mmHg=X_{solute}\times 55.32mmHg\\\\X_{solute}=0.02513$

2. Moles of solute

Now you can calculate the number of moles of water and the number of moles of solute.

Number of moles of water = mass in grams / molar mass

Number of moles of water = 1,250g/18.015 (g/mol) = 69.3866mol

Xsolvent = 1 - Xsolute = 1 - 0.02513 = 0.97487

Xsolvent = moles of solvent / moles of solution

0.97487 = 69.3866mol / moles of solution

moles of solution = 71.1752mol

moles of solute = moles of solution - moles of solvent = 71.1752mol - 69.3866mol = 1.7886mol

3. Mass of urea

Formula:

Mass = number of moles × molar mass

Mass = 1.7886 mol × 60.06 g/mol = 107.42 g

You must round to 3 significant figures: 107 g
