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.

Explanation:

atoms join together to produce elements

Answer:

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.

What is the total amount of heat energy, in
joules, absorbed by 25.0 grams of water when the
temperature of the water increases from 24.0°C to
36.0°C?

Answers

Answer:

0.84

Explanation:

total heat energy =mass ×specific heat capacity (4.2kJ)×temp change

mass=25g convert to kg to get 0.025

specific heat capacity is 4.2

temp change=36.0-24.0=8.0

q = mC∆T

m=25.0

c=24.0

ΔT=36.0

25.0 * 24.0 * 36.0 = 21,600 jules

The equation q =   MC ∆ T, where m is the sample mass, c is the specific heat, and  ΔT is the temperature change, can be used to determine the amount of heat acquired or lost by a sample (q).

How can you figure out how much energy was consumed?

This is simple to perform; to calculate the amount of heat absorbed, multiply the substance's heat capacity by its mass and the temperature change.

The specific heat capacity of a substance is the amount of energy needed to raise the temperature of 1 gram of that substance by 1 degree Celsius. With a value of 4.18 J/g/°C, water has one of the highest heat capacities.

Carbon atoms in single bonds rotate freely. Rotation can occur because the heaviest electron density in the σ bond exists along an imaginary line between two carbon nuclei. Rotation does not change this electron distribution; the bond strength remains constant throughout rotation.

“Sewage"; used water from a community (homes, businesses and industries, stormwater runoff)



Type
Pros
Cons
Pitcher
Low upfront cost; no installation needed.
Does not remove all contaminants; filters must be changed every couple of months and will increase the yearly cost of the filter system; filtration is slow.
Faucet/On the Counter
Relatively inexpensive; can switch between filtered and unfiltered water; easy to install; ideal for drinking and cooking water.
Faucet mounted may not fit on all faucets; decreases flow rate; filters are changed every couple of months.



On the counter may require some installation and can take up space; can sometimes be expensive.
Under-sink
Filter system is out of sight; infrequent filter changes; ideal for drinking and cooking water.
Requires installation; can sometimes be expensive; takes up cabinet space.
Whole House

Professionally installed; very expensive.
Reverse Osmosis
Removes most unwanted contaminants.
5-step process; filters replaced frequently; very expensive; wastes a lot of water.
Distillation

how many moles are in 4.38 of AgNO2

Answers

Answer: 0.02 moles

Explanation:

The number of moles in 4.38 g of AgNO₂ is equal to 0.028 mol.

What is a mole?

A mole can be described as a standard unit that can be utilized to calculate a given number of particles. The constituents counted are usually individually distinct but identical entities.

A mole of the substance can be used to calculate quantities of atoms, molecules, ions, or other particular particles. The quantity of matter can be described as measured by elementary entities.

The number of constituents present in one mole is equal to 6.023× 10 ²³ which is known as Avogadro’s constant.

Given, the mass of AgNO₂ = 4.38 g

The mass of one mole of AgNO₂ =  153.87 g

The number of moles of in 4.38 g of AgNO₂ = 4.38/153.87 = 0.028 mol

Therefore, the number of moles of  AgNO₂ is equal to 0.028 mol.
