Answer:
Option B, atom - molecule - organelle - cell - tissue
Explanation:
Atom is the smallest unit in any living being structure. A group of atoms combines to form molecules. A group of molecules combine to form an organelle. An organelle is a small cellular structure that is found with in a cell. Thus specific group of organelles grouped together form cells. A group of cells arranged in specific manner and specialized in specific function forms the tissue.
Hence, option B is correct.
Answer:
A prediction is when you believe that something is going to happen. Example: I predict that someone will answer this before me.
Predictions can either be right or wrong.
D
More biodiversity often means a more stable food web as their is more to fall back on
The mass number, also known as an atomic mass number or nucleon number, refers to the total number of neutrons and protons (in a combination known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. However, while calculating the mass number, the small contribution of mass from electrons is ignored.
Mass number is equal to Number of protons + Number of neutrons
Mass number = 11 + 7 = 18.
Hence, the correct answer is 18.
