What are traits controlled by?
Answers
Answer:
Most human traits have complex modes of inheritance. They may be controlled by onegene with multiple alleles or by multiple genes. More complexity may be introduced by pleiotropy (one gene, multiple effect) and epistasis (gene-gene interactions). Many genetic disorders are caused by mutations in one or a few genes.

If 150.0 grams of iron at 95.0 °C, is placed in an insulated container containing 500.0 grams of water at 25.0 °C, and both are allowed to come to the same temperature, what will that temperature be? (Cp iron = 0.444J/gC).11. If 10.0 g water at 0.0 °C is mixed with 20.0 g of water at 30.0 °C, what is the final temperature of a mixture?
Answers
The temperature from the metal is transferred to water. Hence the heat lost by the metal is equal to the heat gained by water. Then using calorimetric equation, mass of gold is , 353.8 g.
What is calorimetric ?Calorimetry is an analytical technique used to determine the heat energy absorbed or evolved by a system. The calorimetric equation relating the heat energy q with the mass m, specific heat c and the temperature difference ΔT is :
q = m c ΔT
Here, the heat energy absorbed by water in the calorimeter is equal to the heat evolved from the hot gold metal.
given c of gold = 0.130 J/°C g
c of water = 4.12 J/°C g
temperature difference for water = 45- 20 °C = 25°C
thus, 25°C is lost from the metal.
Then, Mg × 0.130 J/°C g × (150 -25°C ) = 50 g × 4.12 J/°C g × 25°C
then Mg = 353.8 g.
Therefore, mass of gold is 353.8 g.
In similar way, we can find the final temperature of the second system if all other quantities are given.

During translation, the polypeptide chain grows when a covalent bond is formed between the amino acids bound on tRNAs in the ____ site and _____ site E and A
Answers
During translation, the polypeptide chain grows when a covalent bond is formed between the amino acids bound on tRNAs in the P (peptidyl) site and the A (aminoacyl) site of the ribosome.
In the P site (peptidyl site), the peptidyl-tRNA carrying the growing polypeptide chain is located. The A site (aminoacyl site) is where the incoming aminoacyl-tRNA binds, bringing the next amino acid to be added to the growing chain.
As the ribosome moves along the mRNA during translation, the polypeptide chain is elongated when the amino acid on the A site tRNA forms a peptide bond with the polypeptide chain on the P site tRNA. This process continues until a stop codon is reached, terminating translation.

B. Spring balance - a device used for measuring the weight or force of gravity acting on an object.
Explanation:
A Force is any interaction that changes the motion or position of an obkpjectbthatbit is interacting with. Whenever there is an interaction between two objects, there is a force exerted by each of the objects on one themselves.
Forces are generally divided into contact forces and non-contact over field forces.
In contact forces, the two objects physically in contact with each other. Examples of contact forces are push or pull forces, frictional forces, tensional forces, spring forces, etc.
Non-contact forces are forces in which the two objects interacting do no need to be physically in contact with one another. Examples include, gravitational forces, magnetic forces, electrical forces, etc.
Instruments used in measuring forces are known as force gauges.

across that entire time range, in what part of the country are the ph values the lowest (i.e., the most acidic precipitation)? in what part of the country are the ph values the highest (i.e., the least acidic precipitation)?
Answers
Across that entire time range, the part of the country where the pH values are the lowest (most acidic precipitation) is typically found in areas with high industrial activity, such as heavily urbanized regions or areas with significant industrial emissions.
These areas often experience higher levels of air pollution, including sulfur dioxide and nitrogen oxides, which can contribute to acid rain formation.
On the other hand, the part of the country where the pH values are the highest (least acidic precipitation) is typically found in remote or rural areas with minimal industrial activity and lower levels of air pollution. These areas have fewer anthropogenic sources of pollutants and are less impacted by industrial emissions, resulting in less acidic precipitation.
It's important to note that the specific regions with the highest and lowest pH values can vary depending on local atmospheric conditions, prevailing wind patterns, proximity to pollution sources, and other factors. Therefore, a detailed analysis of the data and geographical considerations would be required to determine the exact locations with the highest and lowest pH values across the country.

1.00 pint of milk has a volume of how many milliliters? ( 2 pints = 1 quart)
Answers
1.00 pint of milk is equal to 473.18 milliliters, based on the conversion factor of 1 pint = 473.18 milliliters.
To convert pints to milliliters, we can use the conversion factor of 1 pint = 473.18 milliliters.
Since we have 1.00 pints of milk, we can multiply it by the conversion factor to find the volume in milliliters:
1.00 pint * 473.18 milliliters/pint = 473.18 milliliters.
Therefore, 1.00 pint of milk is equivalent to 473.18 milliliters. It's important to note that this conversion factor is based on the standard definition of a pint, which is equal to 473.18 milliliters. In some countries, the pint may have a different value, so it's essential to use the appropriate conversion factor based on the specific context or region.

calculate the mole in 4.5 molecules of carbon dioxide
Answers
Explanation:
Refer to pic...........
4.51 moles of carbon dioxide
Step by step explanation
To calculate the number of moles in 4.5 molecules of carbon dioxide, we need to use the Avogadro's number, which is the number of particles in one mole of a substance.
Avogadro's number (Nᴀ) is 6.022 x 10²³ particles per mole.
Therefore, we can calculate the number of moles of carbon dioxide as follows:
Number of moles = Number of particles / Avogadro's number
Number of particles of CO2 = 4.5 molecules x 6.022 x 10²³ particles per mole
= 2.711 x 10²⁴ particles
Number of moles of CO2 = 2.711 x 10²⁴ particles / 6.022 x 10²³ particles per mole
= 4.51 moles (rounded to two decimal places)
Therefore, 4.5 molecules of carbon dioxide is equal to 4.51 moles of carbon dioxide

A gas at a volume of 10 L is at a pressure of 2 atm. The volume increases to 50 L. What is new?
Answers
Considering the Boyle's law, if the volume increases to 50 L, the new pressure is 0.4 atm.
Definition of Boyle's lawBoyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: If the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.
Mathematically, Boyle's law states that if the amount of gas and the temperature remain constant, the product of the pressure and the volume always has the same value:
P× V= k
where
P is the pressure.V is the volume.k is a constant.Considering an initial state 1 and a final state 2, it is fulfilled:
P₁× V₁= P₂× V₂
New pressureIn this case, you know:
P₁= 2 atmV₁= 10 LP₂= ? V₂= 50 LReplacing in Boyle's law:
2 atm× 10 L= P₂× 50 L
Solving:
(2 atm× 10 L)÷ 50 L= P₂
0.4 atm= P₂
Finally, the new pressure is 0.4 atm.

The new temperature of the gas if the volume is changed to 4.32L is 16560 K.
What is the new temperature if the volume is changed to 4.32L?Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.
It is expressed as;
V₁/T₁ = V₂/T₂
Where V₂ is the final volume, and T₂ is the final temperature.
