How many chromosomes do you receive from your mother and your father?
Answer: Under normal conditions. Each cell in the human body has 23 pairs of chromosomes (46 in total). Half come from the mother and half from the father.
Explanation: Chromosomes are transferred in pairs.
Under normal conditions. Each cell in the human body has 23 pairs of chromosomes (46 in total). Half come from the mother and half from the father.
Two of these chromosomes (the X and the Y chromosome) determine one’s sex as male or female. They are called sex chromosomes:
• Females have 2 X chromosomes.
• Males have 1 X and 1 Y chromosome.
The mother gives an X chromosome to the child. The father may contribute either X or Y. The chromosome from the father determines if the baby is born male or female.
The remaining chromosomes are called autosomal chromosomes (22 pairs).
1 chromosome from mother+ 1 chromosome from father+ 22 pair autosomal chromosomes= 46
Answer:
We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.

A drop taken from the top of a mixture of alt and water will jot be identical to a drop taken from the bottom of the mixture
A drop taken from the top of a solution of salt and water will not be identical to a drop taken from the bottom of the mixture because the salt and water molecules will be distributed differently throughout the mixture.
What is a solution?
A solution is a homogeneous mixture of two or more substances. In a solution, the solute, which is the substance that is dissolved, is evenly dispersed throughout the solvent, which is the substance that the solute is dissolved in.
Salt is denser than water, so it will tend to settle to the bottom of the mixture over time. This means that a drop taken from the top of the mixture will have a lower concentration of salt than a drop taken from the bottom.
Additionally, due to the process of diffusion, the salt molecules will tend to move from areas of higher concentration to areas of lower concentration, so the concentration of salt will be different at different points throughout the mixture. Therefore, a drop taken from the top will have less salt concentration than a drop taken from the bottom.
Therefore, as the salt and water molecules are distributed differently throughout the mixture a drop from the solution will be identical to that of the bottom of the jar.

1. Three scientists measure the standard meter bar kept at the International Bureau of Standards. Their measurements are 1.09 m, 1.09 m, and 1.08 m. Are their measurements accurate, precise, or both? Why?
Answer:
both
Explanation:
The three scientists' measurements are both accurate and precise.
Accuracy refers to how close a measurement is to the true value, and precision refers to how close multiple measurements are to each other.
In this case, the measurements are accurate because they are all very close to the true value of the standard meter bar, which is defined as 1 meter.
The measurements are precise because all the measurements are very close to each other. They are all within 0.01 m of each other, indicating that the scientists are able to consistently measure the same length, indicating that they are precise in their measurements.
It's worth noting that, even though the measurements are accurate and precise, it's still possible to have a small measurement error, this is because the true value of the standard meter is not 1.09 m or 1.08 m, but the International System of Units defined it to be exactly 1m, and the difference between the measurements and the true value is very small.
The measurements provided by the three scientists are precise but not accurate.
Explanation:The measurements provided by the three scientists can be analyzed in terms of accuracy and precision. Accuracy refers to how close the measured values are to the true value, while precision refers to how close the measured values are to each other. In this case, the measured values are 1.09 m, 1.09 m, and 1.08 m. These measurements are not accurate because they are not equal to the true value of a standard meter bar, which is 1.00 m. However, they are precise because they are very close to each other.
Although the measurements are not accurate, they are consistent with each other, indicating precision in the measurements. In scientific experiments, it is important to have both accuracy and precision. Accurate measurements ensure that the measurement is close to the true value, while precise measurements establish consistency and reliability in the experiment results.

How many chlorine atoms does 7.30 g sample of iron (II) chloride contain? MM FeCl2= 126.8 g/mol
To determine how many chlorine atoms are present in a 7.30 g sample of iron(II) chloride (FeCl2), you can use the molar mass of FeCl2 and the given mass of the sample.
First, you need to convert the mass of the sample from grams to moles using the molar mass of FeCl2:
mass (g) / molar mass (g/mol) = moles
7.30 g / 126.8 g/mol = 0.0578 moles
Iron(II) chloride is composed of one atom of Iron and two atoms of chlorine, so for every 1 mole of FeCl2, there are 2 moles of chlorine atoms.
To find the number of chlorine atoms in the sample, we need to multiply the number of moles of FeCl2 by the number of chlorine atoms per mole:
moles of FeCl2 x (number of chlorine atoms / 1 mole of FeCl2) = moles of chlorine atoms
0.0578 moles x 2 = 0.1156 moles
To convert moles of chlorine atoms to the number of atoms, we need to multiply by Avogadro's number which is 6.022 x 10^23 atoms/mol
0.1156 moles x 6.022 x 10^23 atoms/mol = 6.93 x 10^22 atoms of chlorine.
