Answer:
What Are Red Blood Cells?
Red blood cells carry fresh oxygen throughout the body. This is important to your health. Red blood cells are round with a flattish, indented center, like doughnuts without a hole. Your healthcare provider can check on the size, shape, and health of your red blood cells using a blood test. Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.
Red blood cells are made in the bone marrow. They typically live for about 120 days, and then they die.

inject DNA or RNA into the nucleus of a cell to reproduce.
Answer:
The characteristic of injecting DNA or RNA into the nucleus of a (host) cell corresponds to viruses.
Explanation:
Viruses are not considered living beings, since they are only made up of genetic material covered by a viral capsid and cannot fulfill the functions of a cell. For this reason viruses need to introduce their genetic material into a host cell, to transcribe its genetic code and achieve replication.
Due to their mechanism of reproduction, viruses are biological agents capable of producing disease by altering the conditions of the organisms they use as hosts.

B.The number of protons
C.The number of electrons
D.The number of balance electrons
Answer:
answer is A
Explanation:
Protons and Neutrons will give the mass number
The information would be most helpful in determining the atom's identity is The number of protons and neutrons .
What is atom?The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.
Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus.
The protons are positively charged, while the electrons are negatively charged.
Therefore, The information would be most helpful in determining the atom's identity is The number of protons and neutrons .
