Answer:
Chromosomes are made of DNA
Explanation:
The relationship between chromosomes and DNA is such that chromosomes are made up of DNA.
DNA is deoxyribonucleic acid. It is the main component of the chromosome and basic ingredient for hereditary.
The DNA holds complete sets of instructions that helps control life processes. The chromosome acts as the store house for holding the DNA.
During cell division and reproduction, the chromosomes play very important roles in determining what a person inherits.
Answer:
Chromosones are made of DNA

What is the density of a rock that has a mass of 35 grams and a volume of 7.0 g/mL
Answer: 5
Explanation: Density equals mass divided by volume (D=M/V). Thus, 35/7=5.
The density of a rock : ρ = 5 g/cm³
Further explanationGiven
mass = 35 g
volume = 7 cm³
Required
The density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
Input the value :
ρ = 35 g : 7 cm³
ρ = 5 g/cm³
Balance the equation N2 +H20= NH3 + NO
Answer:
N₂ + 3H₂O → 2NH₃ + 3NO
Explanation:
The reaction expression is given as:
N₂ + H₂O → NH₃ + NO
We are to balance this reaction expression.
To do this, assign a,b,c and d as the coefficients that will balance the expression:
aN₂ + bH₂O → cNH₃ + dNO
Conserving N: 2a = c
H: 2b = 3c
O: b = d
let a = 1, c = 2, b = 3 and d = 3
So;
N₂ + 3H₂O → 2NH₃ + 3NO

The speed of light in a vacuum is 2.998 x 108 m/s. How long does it take for light to circumnavigate the Earth, which has a circumference of around 24,900 miles? Do not enter "seconds" as part of your answer. Watch your Sig Figs!
Answer:
0.13 s
Explanation:
We'll begin by converting 24900 mile to metres (m). This can be obtained as follow:
1 mile = 1609.344 m
Therefore,
24900 mile = 24900 mile × 1609.344 m / 1 mile
24900 mile = 4.01×10⁷ m
Finally, we shall determine the time taken for light to circumnavigate the Earth, this can be obtained as follow:
Distance = 4.01×10⁷ m
Speed = 2.998×10⁸ m/s
Time =?
Speed = distance / time
2.998×10⁸ = 4.01×10⁷ / time
Cross multiply
2.998×10⁸ × time = 4.01×10⁷
Divide both side by 2.998×10⁸
Time = 4.01×10⁷ / 2.998×10⁸
Time = 0.13 s
Thus, it will take 0.13 s for light to circumnavigate the Earth.
How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen has?
2H2 + O2 + 2H20 (5 points)
2 moles of water
4 moles of water
5 moles of water
7 moles of water
Answer: 4
Explanation:
Assume 2 moles O2, not O
O is limiting
2O2 + 4H2 —> 4H2O
so 4 moles water

Answer:
D. Nathan applies enough force through pushes to move the piano
Explanation:
What moves the piano is a net force that is applied through the effort of Nathan on the instrument.
Force is a pull or push on a body.
When force is applied on a body, it causes the state of motion of the body to change.
Therefore, if a body has a net force greater than zero, the body will in likewise begin to move. As Nathan pushes on the piano, it will eventually move.
The distance time graph for four objects is shown below:
Which objects is moving at constant speed?
A. Object A
B. Object B
C. Object C
D. Object D
Answer:
Option A
Explanation:
Remember constant means staying the same so in order to remain constant on the graph the line has to keep going up remaining the same pace. Which means the answer is option A or "Object A." The graph consists of a line going up at a constant speed without any bends or turns which all the other options consist of.
Hope this helps.

What is the mass of reactants in the following equation? N2 + 3H2 ----> 2NH3 Question 3 options: 34.05 amu 31.03 amu 30.02 amu 15.01 amu
Answer:
34.06amu
Explanation:
The reaction expression is given as:
N₂ + 3H₂ → 2NH₃
We are to find the mass of reactants in the equation given;
Here:
Mass of reactants = 2(atomic mass of N) + 3[ 2 x atomic mass of H]
Atomic mass of N = 14.0067amu
Atomic mass of H = 1.008amu
Mass of reactants = 2(14.0067) + 3(2 x 1.008) = 34.06amu

What is the oxidation state of S in HSO42-?
Answer:
+5
Explanation:
As i believe you add all the states up so Oxygen is +2, Sulfur is +2 adn Hydrogen is +1, i believe.
The oxidation state of sulfur (S) in HSO₄²⁻ is equal to +5.
What is the oxidation state?The oxidation state can be described as the oxidation number of the chemical species or ions. The cation exhibits a positive ionic charge while Anion exhibits a negative ionic charge. The number of electrons gained or lost decides the oxidation state of the ions.
In the modern periodic table, the elements on the left side are electropositive (metals) because they donate one or more electrons. The elements on the right side are electronegative as they accept one or more electrons and get a negative charge.
Considering that the charge on the S is x, We know that the charge on the oxygen is -2 and on hydrogen H is +1. The overall charge is -2.
+ 1 + x + 4(-2) = - 2
x - 7 = - 2
x = 7 - 2
x = + 5
Therefore, the charge on sulphur (S) in HSO₄²⁻ is +5.

Martin slowly pours an unknown liquid into a container that originally had some water in it. He is measuring the temperature in the container as he does this.
The temperature in the container rises very fast.
What kind of change is likely to be happening in the container?
A chemical change.
A physical change.
Both a chemical and a physical change.
Neither a chemical nor a physical change.
Answer:
A chemical change.
Explanation:
As the temperature rises fast, the kind of change that can be said to be occurring is a chemical change.
One of the way to know of a chemical change is occurring is that new kinds of matter is formed and also, there is either an evolution or absorption of heat energy in the process.
Since heat is liberated in this change, an exothermic chemical reaction is taking place.
So this is a chemical change.
