One percent of a human's DNA is used for coding Information for the synthesis of proteins.
What is DNA?
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

Element X has three electrons in its outermost orbit.
Element Y has seven electrons in its outermost orbit.
What is the chemical formula of the ionic compound
formed by these elements when they react together?
(Use X and Y as the chemical symbols.)
Answer:
A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B need 2 electrons to complete its octet. so 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet So, the formula will be A2 B3.
The chemical formula of the ionic compound formed by these elements when they react together is X₂⁺Y₃⁻.
What is the chemical formula?A compound's makeup is symbolically represented by its chemical formula. It contains charges, ions, etc.
X has 3 electrons in its furthest outer orbit, while Y has 6 electrons there. In order to complete its octet, X can contribute three electrons, but Y requires two electrons.
So, three atoms of Y will require six electrons to complete their octet, while two atoms of X will release six electrons.
Here, the chemical formula is X₂⁺Y₃⁻, as X is donating an electron so it will gain a positive charge, and Y is gaining an electron, so it will gain a negative charge.
Thus, the chemical formula of the ionic compound is X₂⁺Y₃⁻.

A student increases the temperature of a 300 cm3 balloon from 40 °C to 110 °C.
What will the new volume of the balloon be? Round your answer to one decimal point.
(To convert, add 273.15)
Will Mark brainliest!!!
Answer:
367.1 cm³
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 40 °C
Final temperature (T₂) = 110 °C
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273.15
Initial temperature (T₁) = 40 °C
Initial temperature (T₁) = 40 °C + 273.15
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 110 °C
Final temperature (T₂) = 110 °C + 273.15
Final temperature (T₂) = 383.15 K
Finally, we shall determine the final volume (i.e the new volume) of the balloon. This can be obtained by using the Charles' law equation as illustrated below:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 383.15 K
Final volume (V₂) =?
V₁/T₁ = V₂/T₂
300 / 313.15 = V₂ / 383.15
Cross multiply
313.15 × V₂ = 300 × 383.15
313.15 × V₂ = 114945
Divide both side by 313.15
V₂ = 114945 / 313.15
V₂ = 367.1 cm³
Therefore, the new volume of the balloon is 367.1 cm³

When naming an ionic compound what must always
come first the anion or the cation? (Metal or
nonmetal)
Answer:
Cation / metal
Explanation:
When we named ionic compound we always write cation first. Let's take an example.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and ionic compound is formed. When we naming it we write " sodium " first which indicate sodium cation ( Na⁺) while anion which is Cl⁻ is always written at the end. When we naming ionic compound we ended the name of anion with "ide". Sodium indicate metal while chloride ion indicate non metal. it means metal comes first while naming ionic compound.

If the spring constant is 12.6N/m and a spring is stretched by 0.25m, how much force has been applied?
Answer:
3.15N
Explanation:
We use this equation:
F= k∆x
Where ∆x refers to the amount or stretch or compression and k is the spring constant.
F = force
k = spring constant
∆x = change in length of spring
To find the value of F:
F= k∆x
F= 12.6x0.25
F= 3.15N

The question is incomplete, the complete question is;
The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube, as shown in the diagram below. The volume is measured to be 45.6mL . The atmospheric pressure in the lab is measured as 765 torr , and the equilibrium vapor pressure of water at 298 K is 24 torr .(i) The pressure inside the tube due to the H2(g)
Answer:
741 torr
Explanation:
From the question we can see that the atmospheric pressure in the lab is 765 torr.
The vapour pressure of water = 24 torr
From Dalton's law of partial pressure, we know that;
Total pressure = Pressure of the H2 + Partial pressure of water vapour
Therefore;
Pressure of H2 = Total pressure - Partial pressure of water vapour
Pressure of H2 = 765 torr - 24 torr = 741 torr

Why chloride described as an extended structure?
Answer:
Explanation:
Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.]
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.

What two types of matter are closest in
density? How do you know?
ings.
Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Two people are pushing on a shopping cart from opposite sides. When will the motion of
the shopping cart change?
A. When the two forces are equal
B. When the forces acting on it are unbalanced
C. When both people stop applying a force
D. When the two people push with the same force
Answer:
The answer is B
The motion of the shopping cart will change when the forces acting on the shopping cart are unbalanced. Option B is correct.
According to Newton's first law of motion, an object will remain in its state of motion (either at rest or moving with a constant velocity) unless acted upon by an external force. In this case, the shopping cart is initially at rest or moving with a constant velocity due to the balanced forces exerted by the two people pushing it from opposite sides.
If the two forces applied by the people pushing the cart are equal the cart will continue to move in the same direction with the same velocity. The forces cancel each other out, resulting in a balanced force situation, and there is no change in motion.
However, if the forces applied by the two people pushing the cart are unequal, the forces are unbalanced. This will result in a net force acting on the shopping cart, causing an acceleration and a change in its motion. The cart will either start moving if it was initially at rest or change its speed and/or direction if it was already in motion.
When both people stop applying a force is incorrect because, the cart's motion will continue unchanged if it was already moving with constant velocity due to the absence of any unbalanced forces.
Hence, B. is the correct option.
