What are eukaryotic cells?
Eukaryotic cells are characterized by the presence of a true nucleus, which is a membrane-bound structure that contains the cell's genetic material. They also typically have other membrane-bound organelles, such as mitochondria, Golgi apparatus, and endoplasmic reticulum, which perform specific functions within the cell.
In contrast, prokaryotic cells are characterized by the absence of a true nucleus and other membrane-bound organelles. Instead, they have a single, circular chromosome that is not enclosed in a nucleus, and they have other simple cell structures that perform functions within the cell.
Both plant cells and animal cells are eukaryotic cells, while prokaryotic cells are found in bacteria and other single-celled organisms. Therefore, the statements "Animal cells are prokaryotic" and "Plant cells are prokaryotic" are not true, while the statements "Plant cells are eukaryotic" and "Animal cells are eukaryotic" are true.

What body part contains epithelial tissue, in your answer, explain how cell arrangement helps this body part perform its function.
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.
Cloud cover impacts the temperature on land. Which spheres are involved?
Group of answer choices
Atmosphere, hydrosphere, and geosphere.
Geosphere and biosphere
Hydrosphere, atmosphere and biosphere.
Atmosphere and hydrosphere
Chemicals in the air impact the weathering of rocks. Which two main spheres are involved?
Group of answer choices
Atmosphere and biosphere
Atmosphere and hydrosphere
Atmosphere and geosphere
Hydrosphere and geosphere
Answer:
the atmosphere
Explanation:
The lowest part of the atmosphere on Earth is called the troposphere. The troposphere contains the majority of the atmosphere's mass (about 75–80%). The troposphere is where the majority of clouds are situated, and it is where practically all weather takes place. Thus, option 1.A 2.B is correct.
What cloud cover spheres are involved?Technically, clouds belong to both the hydrosphere and the atmosphere. The water on Earth as a whole is referred to as the hydrosphere. This covers both surface water, such as seas, lakes, and rivers, as well as groundwater. Water in the atmosphere is also a part of the hydrosphere.
The troposphere is almost entirely where clouds are found. Since vertical transfer is constrained by high stability and must pass through the tropopause, which is freezing and has a negligibly low saturation vapour pressure, the stratosphere is extremely dry.
Therefore, Clouds are technically a part of both the hydrosphere and the atmosphere. The hydrosphere refers to all the water on Earth.

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.

Excerpt from The Day of the Bake Sale

1Cindy had spent the last three weeks organizing a bake sale to raise money for her small town's animal shelter. Cindy asked her friends to bake breads and other tasty treats to sell at the bake sale. She had also stayed up late the night before the sale baking blueberry muffins.2Finally, everything was ready for the bake sale. Two of Cindy's friends, Jorge and Pauline, came along on Saturday morning to set up tables. Cindy thought she could do it by herself, but they insisted they come along. They would need several long tables to hold all the supplies for the bake sale. As they set up tables on the town square, Cindy noticed a few dark clouds in the sky. However, she was too busy to stop working and worry about them. As the friends finished putting the tables together, they heard a loud clap of thunder.4Jorge had an idea. They could move the tables under the covered pavilion so everything would stay dry. People bought bread and muffins, and Cindy and her friends raised money for the animal shelter. At the end of the day, Cindy thanked her friends for their help.
I couldn't have done it without you," she told them.
What does it mean when Cindy said, "I couldn't have done it without you" ?
A) Cindy meant that she could not and would not do the bake sale alone!
B) This competition between Cindy and her friends couldn't be done without them.

Based on what you have learned, write two or three sentences explaining how the energy in fossil fuels is converted to electricity.
Sample Response: Fossil fuels are burned to heat water and create steam. Moving steam turns turbines, which generate electricity.
Answer:
Fossil fuels are burned to heat water and create steam. Moving steam turns turbines, which generate electricity.
Explanation:
sample
Fossil fuels are rock-like, gas, or liquid resources that are burned to generate power. They include coal, natural gas, and oil, and are used as an energy source.
What do you mean by fossil fuels?Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock.
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.
Coal, petroleum (crude oil) and natural gas are easy to use for everyday needs that include electricity generation, heating, and transportation. Fossil fuels have become a dominant energy source because they contain a lot of transportable energy in a small package.

Photosynthesis below using your notes. Then fill in the blanks in the sentence.
______+_______→ _______+_______
In the process of photosynthesis, ________ energy is transformed into __________ energy.
alot of pointz
Answer:
Explanation:
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
We can write the overall reaction of this process as:
Sunlight + Carbon Dioxide + Water → Oxygen + Glucose
In the process of photosynthesis, light energy is transformed into chemical energy.
