What is the main difference between a polar covalent bond and a non-polar covalent bond?

Answers

Answer 1

Answer: Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. ... If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.

A researcher conducted an experiment to test whether exposure to high levels of UV radiation (that seen when ozone depletion is at its peak) harms human skin cells. He exposed human skin cells growing in Petri dishes to this level of UV radiation and determined the percentage of cells in each dish that died. He found that 30% of the cells died after 3 days of exposure to high UV radiation exposure. Why would it be unreasonable to conclude that this level of UV radiation exposure is harmful to these cells?

Give three examples of stimuli that your sensory receptors are responding

Answers

Sensory receptors are cells which are able to receive external stimuli such as light, temperature and pressure. These receptors send the information they receive to the brain and it is understood as a sensation.

Examples of sensory receptors are the cone and rod cells in the retina which receive light, pressure sensors on the skin, temperature sensors on the skin, taste cells on the tongue and many more.

Which type of tissue covers the body, lines internal surfaces and forms glands?a. nervous tissue
b. connective tissue
c. muscle tissue
d. epithelial tissue

Answers

Answer: Option D.

Epithelial tissues.

Explanation:

Epithelial Tissues are tissues that are composed of cells that are packed in sheet and tightly connected to each other. These tissues covers the body surfaces, lines body cavities, lines internal organs and forms gland. An example of epithelial tissue is the epidermis, an outer layer of the skin.

Epithelial Tissues functions in secretions, protection, selective absorption, filtration, excretion e.t.c in the body.

Final answer:

An d. Epithelial tissue is the type of tissue that covers the body, lines internal surfaces, and forms glands. It serves as a protective barrier and aids in absorption and secretion.

Explanation:

Epithelial tissue covers the body, lines internal surfaces, and forms glands. It serves as a protective barrier and helps in absorption and secretion. Examples of epithelial tissue include the skin, lining of the digestive system, and the lining of the lungs. It is a type of animal tissue that forms the covering of body surfaces, linings of cavities and organs, and the outer layer of skin.

It is composed of tightly packed cells arranged in sheets and serves functions such as protection, absorption, secretion, and sensation. Epithelial tissues come in various shapes and layers, depending on their location and function in the body.
