Head Area: The nose and mouth take in oxygen that goes through the throat and into the lungs. There are 2 ways, but a little flap opens when oxygen comes in and closes right after. This is used so food doesn't get in the wrong way.
Chest Area: Capillaries in the lungs move the oxygen to the heart to pump it throughout the body.
Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.

Answer:skeletal evidence of evolution
Explanation:
So I’m not sure the best way to explain this, will edit in one second
So basically some creatures have leftover bones or other features that have no benefit but they also aren’t detrimental, and they are the result of evolution. There is a great video on bad animal skeletons by Sam O Nella Academy, it has some strong languages so inappropriate jokes, probably, all of them do, and this is middle school biology so watch at your own risk, but I think a pint you could bring up that your teacher would be impressed by is really any animal with a weird skeleton, for example dolphins who just have a random bone image where their legs used to be, they obviously don’t have legs but their ancestors did and to this day they still have a random bit of bone where an ancestor of theirs used to have legs, so skeletons help connect what a common ancestor looked like to what the current species looks like through similar bone structure and/or left over bones, such as dolphins who have a plate where an ancestor used to have legs
Answer:
The chemical reaction is: AB + CD ---> AC + BD (ΔH= - )
Explanation:
After the reaction between two reactants, two products are generated.
As the products have less energy than the reactants, this energy is released and ΔH is negative
DNA Polymerases type of enzyme ensures that the correct base for growing the chain is aligned with the template chain.
<h3>What is DNA Polymerase?</h3>
- The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase.
- These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.
- DNA polymerase "reads" the pre existing DNA strands throughout this process to produce two new strands that are identical to the preexisting ones.
- Deoxyribonucleotides, the components of DNA, are synthesized by DNA polymerase as its primary purpose.
- The nucleotides and bases found on each strand of the original DNA molecule are paired to form the DNA copies.
- This coupling always occurs in certain pairings, with cytosine and guanine constituting one pair and thymine and adenine forming the other.
- RNA polymerases, on the other hand, create RNA from ribonucleotides that are either found in RNA or DNA.
