What is epithelium?</h3>
- Layers of cells known as "epithelium" line hollow organs and glands.
- These cells are also responsible for the body's exterior.
- The epithelium is a type of body tissue that covers all of the internal and exterior body surfaces, lines hollow organs and body cavities, and makes up the majority of glandular tissue.
- They make up the majority of the tissue in glands, line body cavities and hollow organs, and cover all of the body's surfaces.
- They conduct a multitude of activities that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
- Because word was first used to describe the translucent layer of tiny tissue "nipples" on the lip, epithelium got its name.
- The plural version of the term is epithelia, and it has both mass and count connotations.
- A form of animal tissue known as an epithelium is composed of tightly packed cells, or epithelial cells, that lie atop a basement membrane.
- Its purpose is to cover or line different bodily surfaces and cavities.

Answer:
A. The poles are opposite
Explanation:
Magnets are object that produce magnetic fields, which are regions of space that exert a forces on charged particles in motion or on other magnets.
Every magnet has 2 opposite poles, which are labelled by convention as North Pole and South Pole; the lines of the magnetic field of a magnet go out from the North Pole and go into the South Pole.
Magnetic poles always exist in pair: it means, every magnet always contains a North Pole and a South Pole. If a magnet is cut in a half, each half of the magnet will still have a North Pole and a South Pole.
Each pole exerts a force on another pole; in particular, we have:
- Like poles (north-north or south-south) repel each other
- Opposite poles (north-south) attract each other
In this problem, a magnet is attracted to a metal object: this means that the two poles must be of opposite polarity. Therefore, the correct option is
A. The poles are opposite
Answer:
Dominant
Explanation:
If it appears in all generations it is a dominant gene
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Answer: A
Explanation: There is no need to conduct and experiment if you already know the answer
