Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, <u>all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons</u>.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, <u>it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different</u>. Hence, the correct option is B
Answer:
the answer is increase the number of coils
Explanation:
1) Because we are constantly discovering new species of organisms, the system of classification is growing.
2) In order for scientists to write, learn, and retrieve data about organisms, there most be an organized filing system in place.
Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.
<h3>What is meant by Pathogen?</h3>
- A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
- Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
- The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
- Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.
Therefore the correct option is D) can activate cells of the adaptive immune system.
