Answer:
The options are not shown, however the attached picture should show the parts of an atom and the relationships between the three basic parts of an atom being Protons, Neutrons and Electrons.
In the nucleus of an atom, there are both Neutrons and Protons whilst the rings of the atom will contain the electrons.
The protons carry a positive charge and the electrons a negative one.
When the protons and neutrons are added together, these will give the mass number of the atom so the mass number of this atom is 32.
For a neutral atom, the Protons and the Electrons should be equal. Notice how there are 16 protons (+) in the nucleus and 16 electrons (-) on the rings.
Answer:
<h2>Facilitated diffusion
.</h2>
Explanation:
1. Diffusion: it is the net passive movement of particles from higher concentration to lower concentration. Diffusion continues until the concentration of substances is equal through out.
2. Facilitated diffusion: is the process of passive transport of molecules or ions across a biological membrane and requires (via) a specific carrier protein.
3. Facilitated diffusion is passive type and require specific protein and it requires no energy from the cell.
4. It requires specific proteins through which molecules move from one side to another.
I believe the answer is C
Hope this helps you have a good night
Answer:
To be sure, the patient need complementary studies.
Explanation:
In a pap test sometimes the result can be as "abnormal cells" but that does nt mean cancer directly. The doctor need to do a complementary study like a colposcopy to check if the cells are abnormal, and in which are is the damage.
Also the etiology could be due to the papiloma virus, that in most of the cases cause abnormal cells, that lead into cancer. But, in other situations, some other bacteria can be infected the reproductive system and have a false result due to other bacteria like yeast or Trichomonas.
Hope this is useful.
