Having a widow's peak like Wentworth
Miller is dominant.
Not having a widow's peak, like Rihanna, is
recessive.
10) If Wentworth Miller is Aa, and he and Rihanna had children, what are the possible
phenotypes and genotypes of their children?
Answers
Answer:
Aa 50% Widow's peak, aa 50% no Widow's peak
Explanation:
In the crossing over the phenotypes of their children, 50% are widow's peak (aa), while 50% are not widow's peak (Aa) because the widow's peak genes only show trait when it is in recessive condition.
What is a recessive condition?An inheritance pattern known as autosomal recessive inheritance allows a genetic disease or characteristic to be transferred from parent to offspring.
When a kid receives one altered (mutated) gene from each parent, a genetic disease may result. An autosomal recessive disorder is typically not present in the parents of a kid who has it.
Describes a property that can only be observed when a genotype is homozygous, a feature that is often concealed by other inherited qualities but survives in a population of heterozygous genotypes.
The crossing between Aa X Aa
Gametes: A and a.
The cross is attached in the image below.
Therefore, the gene's dominant allele, which is expressed when its alleles are distinct, is the case when the alleles are different. The recessive allele effect is hidden by the other allele's effect.

The density of air at STP is 1.285 g/L. Which of the following cannot be used to fill a balloon that will float in air at STP?
Answers
NO can't be used to fill a balloon
Further explanationConditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
Answer options that need to be added :
a. Ne
b. NO
c. NH₃
d. CH₄
e. HF
will float in air ⇒ element or compound to fill the balloon, its density must be less than < 1.285 g/L
We can use the ideal gas formula ta find density :
[tex]\tt \rho=\dfrac{P.MW}{RT}[/tex]
Because at STP, then the constant value is
[tex]\tt \rho=\dfrac{1~atm\times MW}{0.08205\times 273.15~K}\\\\\rho=0.0446\times MW[/tex]
So that the density is determined from the MW(molecular weight) of each element or compound
a. NeAr = 20.1797 g/mol
[tex]\tt \rho=0.0446\times 20.1797=0.9~g/L[/tex]

of 68.5%. What is the average atomic mass of element X?
Answers
Answer:
amu = 34.055 or 34.1
Explanation:
to calculate the average mass, first convert the percentages into decimals. Then, calculate the mass numbers. To get this number, multiply the decimal by the mass number for each isotope and, then add them together.
( 0.315 x 32 ) + (0.685 x 35 ) = 34.055
what is 1.23 x 10^-3 in standard notation
Answers
Answer:
=0.00123
Explanation:
Look at the attachments below
Hope this helps (:
Answer:
0.00123
Explanation:
Standard notation is the normal way of writing numbers. Examples include 1, 2, and 10. The number 1.23 x 10^-3 is written in scientific notation. The decimal goes after the first nonzero integer and it is multiplied by a power of 10. The power or exponent attached to the 10 tells you how many places over you need to move the decimal to get back into scientific notation. Examples include 1.00 x 10^2 (representing 100 in standard form because you would move the decimal two places to the right.), 2.0 x 10^1 (representing 20 in standard form because you would move the decimal one place to the right), and 3.0 x 10^-4 (representing 0.0003 in standard form because you would move the decimal four places to the left since it is a negative exponent).
The negative (-3) exponent in 1.23 x 10^-3 indicated to move the decimal three places to the left. If it was positive, you would move it three places to the right.
In 1.23 x 10^-3 move the decimal to the left 1 place to get:
0.123
two places to get:
0.0123
and a third place to get:
0.00123

D both the energy and molecules are trapped in the system.
Answers
Answer:
A) Energy and Water molecules are free to escape into the surrounding environment.
Explanation:
Hello! This is the correct answer! (I took the K12 test)
I hope this helps! Have a blessed day! :)
When boiling a pot of water on the stove without a lid on the pot, the energy and water molecules are free to escape into the surrounding environment.
What is boiling?Boiling point of a substance is the temperature at which the substance changes from liquid state to gaseous state where these two systems comes in equilibrium.
Thus when a liquid is boiled, the liquid molecules get more energy to move apart and they escape into gaseous state. With change in state of the substance, the energy also be transferred from the liquid to the environment.
If the pot is closed with a lid, then both energy can be transferred but molecules get trapped inside. But here the pot is open and thus the gas molecules and energy are free to move outside.
Therefore, option A is correct for the boiling of water in an open pot.

The historical order of atomic models from the earliest to the most recent is as: Hard sphere model, electron shell model, and wave mechanical model. Therefore, option (A) is correct.
What is the atomic model?The atomic model can be described as the model used to describe the structure and composition of the atom. The atom as a primary component of matter has been under extensive study to understand the universe.
In the classical model of an atom, the atom is made of smaller particles with an electrical charge called electrons, protons, and neutrons. To understand the atomic models, it is important to understand how these particles make up the atom.
There are five principal atomic models that have been proposed over time, which are Dalton’s atomic model, Thomson’s atomic model, Rutherford’s atomic model, Bohr’s atomic model, and the quantum atomic model.

Answers
4.94 x c . (Tm-23.6)=C.(23-6-21.9)+123.13 x c. (23.6-21.9)
Further explanationThe law of conservation of energy can be applied to heat changes, ie the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
A calorimeter is a device used to measure the specific heat of material
A metal is put into a calorimeter that contains water and there will be heat transfer:
[tex]\tt \displaystyle m_mc_m (T_m-T)=m_wc_w(T-Tw)[/tex]
m = metal
w = water
T = the final temperature of the mixture
mass of metal =(Nickel) = 4.94 g
mass of calorimeter = 12.5 g
mass of water = 123.13 g (135.63 - 12.5)
The equation
Q released (metal) = Q absorbed(calorimeter+water)
Qmetal = 4.94 x c . (Tm-23.60)Q calorimeter = C.(23-6-21.9) --> C = heat capacity of calorimeterQ water = 123.13 x c. (23.6-21.9)The equation :
