The parts of the heart are the atria, ventricles, septum, valves. The atria collects oxygenated blood that has returned from the lungs.The ventricles , receive blood from the atria. The septum it separates the left atrium and ventricle from the right atrium and ventricle. Finally, the valves<span> separate the various parts of the heart from one another. They allow blood into places it’s supposed to be and keep it out of places it’s not supposed to be.
Undoubtedly, there are more parts of the heart but these are the main functions.

The chemical composition of bone is made up of collagen and calcium, which makes bones stronger
Answer: The purpose of transcription is to move the information from the DNA to the ribosomes with the help of mRNA. Then we have translation it occurs on ribosomes and its purpose is to assemble amino acids into proteins.
Explanation:
the steps of transcription:
1. unzipping the DNA
2. build the RNA molecule
3. detach the mRNA molecule
4. rewinds the DNA molecule
If u want the steps of translation tell me :)
A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Which of the following processes is most likely going to occur in the swimmer's muscle cells during the competition? (2 points)
A. Aerobic respiration would continue until oxygen is no longer available, leading to cell death.
B. Aerobic respiration will continue to make the same amount of ATP since oxygen is not required.
C. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen.
D. Anaerobic respiration will produce more ATP than the process used in the presence of oxygen.
<u>Answer:</u>
A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen and it is the process happens in the swimmer's muscle cells during competition.
<u>Explanation:</u>
- A Swimming sprinter will spend his maximum energy while to cover a short distance in his competition. Quickly he will reduce his oxygen level.
- Oxygen will produce an ATP molecule (Adenosine Triphosphate) which is required for a sprinter.
- The ATP molecule will produce energy for the cells. Aerobic respiration takes place only when in the presence of oxygen.
- While swimming they will not get enough oxygen so the Anaerobic respiration takes place to produce ATP molecule.
I think the correct answer from the choices listed above is option A. The anatomical adaptation which helps an elephant regulate its body temperature are its large ears increase surface area so that more heat is lost by radiation. Heat can be released as they flap these ears. So there is your correct answer
