What is probability, and how is it used with Punnett squares to predict the outcomes of genetic crosses?

weeeeeb [17]

Answer:

Probability is the chance that a given event will occur. The principle of probability allows us to predict the possible combinations of phenotypes in a genetic cross by using a diagram called Punnett squares. This diagram represents alleles and gives us the genetic variations formed during a cross. For example, a flower has one dominant allele for a blue color, which is represented by capital T, and one recessive allele for a pink color, which is represented by small t. When this flower is crossed with another flowering plant with the same type of alleles, which is Tt, the combinations produced for their offspring includes TT, Tt, tT, and tt.

Answer:

The four Inner planets have slower orbits, slower pin, no rings and they are made of rock and metal. The four Outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.

The Outer planets are made of hydrogen and helium, so they are called gas giants.

There are 258 g of MgCl2/liter. What is the molarity of the solution?

Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

amount of moles= 2.7098 moles

Replacing in the definition of molarity:

258 g of MgCl₂/liter= 2.7098 moles of MgCl₂/liter

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

The correct option is:

B) lipid

Explanation:

A lipid is a biomolecule that is solvable in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to melt another naturally happening hydrocarbon is.Any of a large group of organic mixtures that are oily to the touch and difficult in water. Lipids comprise fatty acids, oils, waxes, sterols, and triglycerides. They are a source of stored energy and are an element of cell membranes.
