Answer:
B) Multicellular Simple gland
Explanation:
Exocrine Glands:Glands that secrete their products onto the apical(or epithelia) surface directly or via epithelial ducts or tubes that are connected to the apical surface. These Exocrine glands are composed of highly specialized epithelial cells..
Exocrine glands can either be branched or Unbranched based on the arrangement.
*Multicellular simple glands*:Glands that have an *unbranched duct* into which cells secrete. Each secretory portion empties separately on an epithelial surface.
Answer:
The number of protons in it.
Explanation:
There are two properties that can be used to identify an element:
- the atomic number
- the number of protons in an atom.
The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question
Answer:Answer:
For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
For 2:
A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example: is a compound made out of atoms of carbon and oxygen.
Hence, the correct answer is Option 2.
