Answer:

C. Gene

Explanation:

The gene is a segment of a DNA (deoxyribonucleic acid) molecule responsible for genetically inherited traits. Each gene consists of a specific DNA sequence that contains a code (instructions) to produce a protein that performs a specific function in the body.

Most genes are contained in chromosomes. The chromosome consists of a long strand of DNA wrapped around a special protein called histone. Most chromosomes contain several different genes. Human cells contain 23 pairs of chromosomes - one pair of sexual chromosomes (XX in women or XY in men) plus 22 pairs of nonsexual chromosomes called autosomes. Chromosomes are transmitted from parents to children through sperm and eggs. One chromosome from each pair is inherited from the mother and the other from the father.

The density of a rock that was a mass of 454 grams and a volume of 100 cm3

puteri [66]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass of rock = 454 g

volume = 100 cm³

The density of the rock is

$density = \frac{454}{100} = \frac{227}{50} \\$

We have the final answer as

Hope this helps you

A sample of gas has a volume of 8.20 L at 0.750 atm and 375 K. What volume (in L) does the gas occupy at 817 torr and 325 K?

lys-0071 [83]

The new volume occupied by the sample of gas is 4.96L.

Given the data in the question;

Initila pressure; $P_1 = 0.750atm$

Final pressure; $P_2 = 817torr = 1.075atm$

Inital temperature; $T_1 = 375K$

Final temperature; $T_2 = 325K$

Initial Volume; $V_1 = 8.20L$

Final Volume; $V_2 = \ ?$

<h3>Combined gas law</h3>

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$

To calculate the new volume the gas occupy, we subtsitute our given values into the expression above.

$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\ \\ P_1V_1T_2 = P_2V_2T_1\\\\0.750atm * 8.20L * 325K = 1.075atm * V_2 * 375K\\\\1998.75LatmK = 403.125atmK * V_2\\\\V_2 = \frac{1998.75LatmK}{403.125atmK} \\\\V_2 = 4.96L$

Therefore, the new volume occupied by the sample of gas is 4.96L.
