The particles that make up matter are the atoms.
Atoms do not change during a chemical change. They do not either during a physical change.
During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.
For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.
The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.
Answer:
The human genome contains around 30 000 genes, each of which codes for one protein. Large stretches of DNA in the human genome are transcribed but do not code for proteins. ... The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
Explanation:
Answer: A BMI(Body mass index) is the ratio for determination of the total fat of the body. It is considered ideal if the BMI value is ranging from 18.5 to 24.9
Explanation: Body mass index(BMI) defines whether the person is over weight or underweight by calculating the overall fat of the body . A range of 18.5 to 24.9 BMI value is considered to be healthy. If the value is higher than 30 then it is considered as person is obese/overweight and if the value is below 18.5 it is considered to be underweight.
The answer to this question would be: impaired gas exchange.
<span>Pneumocystis jiroveci attack the lungs and cause pneumonia. Pneumonia will reduce the lungs function and might cause dyspnea or even respiratory distress in severe cases. The ulcer in the feet wouldn't kill the patient but respiratory distress would.</span>
