Answer:
Hh
Explanation:
if you have a dominant allele and a recessive allele they'd be different (heterozygous)
If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
What is genotypes?The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.
The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
Therefore, Hh is the genotypes of the parents shown in the pedigree.

Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

What is the % of each element in (NH4)2(SO4)?
Nitrogen=21.1999%
Hydrogen=6.1023%
Sulfur=24.2660%
The percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.
What is percent composition?The percent composition is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.It helps in elemental analysis of a given compound by giving proportions in which they are present.
Percent composition of N= 28/132.14×100=21.18%
Percent composition of H=8/132.14×100=6.05%
Percent composition of S=32/132.14×100=24.21%
Percent composition of O=64/132.14×100=48.43%.
Thus, the percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.

Scenario
On Halloween, children prepared to go trick-or-treating with glow sticks. They prepared two glow sticks (“Glow Stick In” and “Glow Stick Out”) following the directions below. The light intensity was given a value of 10 for both Glow Stick In and Glow Stick Out. At 6:00, the children left Glow Stick In inside of the 25oC house and took Glow Stick Out outside in 10oC weather. At 8:00, they noticed the light intensity of Glow Stick Out at 10oC had decreased to 5. They immediately returned home and noticed the light intensity of Glow Stick In at 25oC had decreased to 7. At 9:00, both glow sticks were at 25oC. Glow Stick In had a light intensity of 6, and Glow Stick Out had a light intensity of 8.
Using at least two scientific principles, write a scientific explanation that includes evidence that justifies or describes the change in light intensity of both glow sticks. Please use claim evidence reasoning.

1. If you have 5g of pennies how many dozen pennies do you have?
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen

Please help! Find the distance to each destination in AU. Use the correct conversion factor.
Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au

PLease HELP How many molecules of CO2 are there in 55 grams of CO2?
Answer:
1.2mol
Explanation:
Determine the g/mol of CO2
O - 16g/mol (based on my data booklet)
C - 12.01g/mol (based on my data booklet)
Then add these values up for the g/mol of CO2
16+16+12.01= 44.01g/mol
Then write out the formula
mol = mass/molar mass
n= m/M
n = 55/44.01
n= 1.24971597
and depending on what significant digits you need (based on info, ill do it to 2 terms)
n = 1.2 mol
Molar mass is defined as the mass in grams of one mole of a substance. 1.2 molecules of CO2 are there in 55 grams of CO2.
What do you mean by molar mass ?The term molar mass is defined as the mass of a chemical compound divided by its amount-of-substance measured in moles. It is represented by the symbol "M". The units of molar mass are grams per mole, abbreviated as g/mol.
The weight of one mole of a sample is defined as its molar mass. To calculate a molecule's molecular mass, multiply the subscript by the atomic mass of each element in the molecule, then add the masses of all the elements in the molecule.
Molar mass of Oxygen - 16g/mol
Molar mass of Carbon - 12.01g/mol
Then add these values up for the g/mol of CO₂
Molar mass of CO₂ = 16+16+12.01
= 44.01g/mol
Then,
The number of mole = mass / molar mass
n = m / M
n = 55 / 44.01
n = 1.24971597
n = 1.2 mole
Thus, 1.2 molecules of CO2 are there in 55 grams of CO2.

Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No
Answer:
The liquid decreases in temperature and its particles lose kinetic energy.
Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air
