Answer:
B. 6
Explanation:
The atomic number of an atom is the number of protons in the nucleus of that atom. So, for example, if an atom has 15 protons in its nucleus, its atomic number is 15.
Protons are positively charged. Since this atom's nucleus contains 6 particles that are positively charged, we can infer that those particles are protons, and that would mean that the atom has 6 protons. Like I said earlier, the number of protons in an atom is the atomic number, so this atom has an atomic number of 6.
Hopefully that's helpful! :)
Flagella provide motility to a sperm cell, cilia act as sensory "antennae" in many cells and microvilli Increase a cell surface area
<h3>What is flagella, cilia and microvilli?</h3>
Flagella is a hair-like structure used by cells for locomotion or movement. The sperm makes use of flagella for locomotion.
Cilia is a hair-like structure that is found on the surface of organisms which are sensitive to touch.
Microvilli is a hair-like structure that is richly fortified with blood vessels found in areas for absorption. This is because it increases the surface area.

Great question ! It is the nucleus.
<u>Answer</u>:
According to the predictions of the second law of thermodynamics
"heat is released in the process".
<u>Explanation</u>:
The "second law of thermodynamics states that total entropy of the isolated system can never be decreased over but is constant if all processes are reversible". Similarly in photosynthesis not all the energy are taken by the plants, some reflected and some are lost as well. However, the loss of energy to the surrounding results in increase of entropy. The energy used in the photosynthesis is the light. The source of this light is sunlight.
