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.

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.

Genes passed down from parents can combine in a child in a new way to best explain it.
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.

Leaf has been known as the basic site of photosynthesis it means the process of photosynthesis occurs in leaf. The main function of leaf has to produce food material for plants which will help plants to get nourished.
There are mainly two types of leaves and these are simple and compound leaves. The simple leaf is one in which single lamina has attached to the stem by the help of petiole and compound leaf is the one in which lamina has been divided into leaflets.

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.

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.

A. Sweating and shredding fur
B. Spitting and shredding fur
C. Sensing danger and sweating
D. Sensing danger and shredding fur
Answer:
Sensing danger and sweating
Answer:
