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.
______ transport moves substances from an area of high concentration to an area of low concentration.

What are the functions of genes?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions for making molecules called proteins. However, many genes do not code for proteins.
Our genes carry information that is passed down from generation to generation. For example, one child has blonde hair like his mother because of his genes, while his siblings have brown hair like his father.
Genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various actions.

When an autotroph does photosynthesis, what energy transformation takes place?
Answer:
Photosynthesis transforms solar energy (sun) into chemical energy
Explanation:
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions (light-dependent and light-independent) that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen. Energy from sunlight is absorbed by chlorophyll (the green pigment) and that energy is converted into stored chemical energy.
Also, strange question, considering the energy transformation in autotrophs is photosynthesis.

Peptic ulcers are sores in the lining of the stomach, they are cause by bacterial infection. The bacteria increases the acid in the stomach and ears away at the stomach linings, which makes sores. When this happens, what tissue does the acid remove?
Answer:
Peptic ulcer disease occurs when open sores, or ulcers, form in the stomach or first part of the small intestine. Many cases of peptic ulcer disease develop because a bacterial infection eats away the protective lining of the digestive system. People who frequently take pain relievers are more likely to develop ulcers.
Explanation:
Answer:
The acid in peptic ulcers can damage stomach tissue.
Explanation:
Ulcers form when the intestine or stomach's protective layer is broken down. When this happens, digestive juices - which contain hydrochloric acid an anzyme called pepsin - can damage the intestine or stomach tissue.

Once scientists understood the short-term impact of the zebra mussel invasion, they started to wonder about the invasion's long-term impact on the ecosystem. Why might the Hudson River ecosystem look different many years after the zebra mussel invasion than it did just a few years after the invasion?
Answer:
In spite of their small size (often no bigger than a penny) zebra mussels cause far-reaching damage to water structures and native ecosystems. They also negatively impact aquatic ecosystems by harming native organisms. In huge numbers, they out-compete other filter feeders, starving them.
The Hudson River ecosystem might look different many years after the zebra mussel invasion than it did just a few years after the invasion due to the cascading effects of the invasion on the ecosystem.
What is The Hudson River ecosystem?The Hudson River ecosystem is a complex and diverse network of living and non-living components that includes everything from microorganisms and plankton to fish, birds, and mammals. The ecosystem is influenced by a range of natural and human-made factors, including climate, water quality, land use, and pollution.
It supports a variety of important ecological, economic, and cultural services, including fisheries, recreation, transportation, and aesthetic value. However, the ecosystem has also faced a range of challenges, including habitat destruction, overfishing, pollution, and invasive species, such as the zebra mussel.
For example, zebra mussels are filter feeders that can dramatically reduce the amount of plankton in the water, which can in turn affect the entire food chain. Over time, these changes can lead to a shift in the species composition and overall structure of the ecosystem, which may be evident many years after the initial invasion.

True or False an overtone occurs when two or more sound waves are produced at the same time.
1. True.
2. False
Answer:
True.
Explanation:
An overtone is any frequency greater than the fundamental frequency of a sound.
Overtone, in acoustics, tone sounding above the fundamental tone when a string or air column vibrates as a whole, producing the fundamental, or first harmonic. If it vibrates in sections, it produces overtones, or harmonics. The listener normally hears the fundamental pitch clearly; with concentration, overtones may be heard.

As time progressed and technology improved, microscopes were able to give clearer images of extremely tiny objects. How did this development advance the cell theory?
Answer:
Robert Hooke is accredited with observing the first cells in 1665. At that time, Robert Hooke used a microscope to look at cork cells.
In 1670, Antoni van Leeuwenhoek was accredited with being the first scientist to discover pond life. He used lenses to make the discovery.
Robert Brown (1773-1858) used a microscope to discover the nucleus.
Explanation:
The development of technology extremely advances the concept of cell theory to a larger extent. This facilitates scientists to deliver a more accurate and detailed image of tiny objects like cells and their organelles.
What are the three assumptions of cell theory?The three assumptions of the cell theory are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms. A Cell is the basic structural and functional unit of organisms.Prior to the cell theory, English scientist Robert Hooke in 1665, first discovered a dead cell in a thin slice of bottle cork under a microscope. Later in 1674, Antony Von Leeuwenhoek discovered the living cell for the first time with the improved version of the microscope.
In 1836, Robert Brown discovered a cell's nucleus. Then it comes to the time of 1839 when cell theory was proposed by Theodore Schwann and M. Schleiden. Till then, there was a lot of improvement is seen in the field of technology which complete changes the purpose and method of scientific analysis.
Therefore, the development of technology extremely advances the concept of cell theory to a larger extent.
