Answer:

If you jump up and down on Earth, what happens? You go right back down. If the gravitational force wasn't going down, we wouldn't even be able to stand on Earth without floating away.

Do you agree that a reduction in our use of energy would sum like an historical step backwards?why or why not?
Ad libitum [116K]

Answer:

In my opinion, a reduction in our use of energy would not be a historical step backwards.

Explanation:

We already know that humanity's consumption of fossil fuels is wreaking havoc on the ecosystem. Fossil fuels pollute the environment where they are generated and utilized, and their continued usage harms the climate of the entire world. Nonetheless, altering our behaviors in a significant sense has proven to be quite difficult. As a result, it is not impossible to reduce our energy use significantly, but we may take little efforts to change the way we create energy, such as using fossil fuels. Because fossil fuels are so detrimental to our environment, we should try to reduce its use, but not at the risk of improving our surroundings. There are several methods to change the way we utilize energy now into something more sustainable.

snow_tiger [21]

Answer:

Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.

explain how cell arrangement helps this body part perform its function. :

Its tightly packed cells allow for protection against harmful substances.

Explanation:

Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. The free surface of epithelial tissue is usually exposed to fluid or the air, while the bottom surface is attached to a basement membrane.

The cells in epithelial tissue are very closely packed together and joined with little space between them. With its tightly packed structure, we would expect epithelial tissue to serve some type of barrier and protective function and that is certainly the case. For example, the skin is composed of a layer of epithelial tissue (epidermis) that is supported by a layer of connective tissue. It protects the internal structures of the body from damage and dehydration.

Epithelial tissue also helps to protect against microorganisms. The skin is the body's first line of defense against bacteria, viruses, and other microbes.

Epithelial tissue functions to absorb, secrete, and excrete substances. In the intestines, this tissue absorbs nutrients during digestion. Epithelial tissue in glands secrete hormones, enzymes, and other substances. Epithelial tissue in the kidneys excrete wastes, and in the sweat glands excrete perspiration.

Epithelial tissue also has a sensory function as it contains sensory nerves in areas such as the skin, tongue, nose, and ears.

Ciliated epithelial tissue can be found in areas such as the female reproductive tract and the respiratory tract. Cilia are hair-like protrusions that help propel substances, such as dust particles or female gametes, in the proper direction.
