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.

Excerpt from The Day of the Bake Sale
Jenna McKean
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.
C) The bake sale was quite an undertaking, a great deal of work for just one person.

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.

What is the main idea of this text? Before the invasion, scientists developed computer models to predict the effect of the zebra mussels. But they were still surprised by what happened. By 1992, there were so many zebra mussels, scientists estimate
they were filtering a volume of water equal to all of the water in the estuary every 1-4 days during the summer. In the years right after the invasion, phytoplankton fell by 80 percent. Zooplankton (which eat phytoplankton) declined by half. And the smallest zooplankton (called micro-zooplankton), fell by about 90 percent. By 1994, scientists hypothesized that zebra mussels were responsible for these changes. The mussels were filtering huge amounts of phytoplankton from the water. Less phytoplankton meant less food for zooplankton, so their numbers were shrinking too. Competition was taking place and the
zebra mussels seemed to be winning.
A. In the years right after the invasion, zebra mussels evolved and adapted to the Hudson River ecosystem.
B. In the years right after the invasion, zebra mussels caused a number of changes in the Hudson River ecosystem and food web.
C. In the years right after the invasion, zebra mussels did not have a major impact on the Hudson River ecosystem or food web.
D. At first, zebra mussels did not have any impact on the Hudson River ecosystem, but their impact increased over time.
please help me I will give out the brain thing and extra points.
Answer:
B
Explanation:
I don't really know to be honest. I would guess it's B because it mentions the impacts, such as increased population in the mussels and decrease in zooplankton and phytoplankton.

B.) Carbon dioxide + water ---(light energy)---> glucose + oxygen
C.) Glucose + water --------> oxygen + carbon dioxide = energy (ATP)
D.) Carbon dioxide + energy ---(light energy)---> oxygen + water + glucose
Cellular respiration is the vital living process to produce ATP from food. The word equation that best represents the process is Glucose + oxygen → carbon dioxide + water + energy (ATP). Thus, option A is correct.
What is cellular respiration?Cellular respiration is the chemical series that involves the production of energy molecules (ATP) to power cellular activities and metabolic functions. It involves, glycolysis, Kreb's cycle (TCA), and oxidative phosphorylation to break the sugar molecules.
The word equation for cellular respiration can be given as:
Glucose + oxygen → carbon dioxide + water + energy (ATP)
Here, glucose and oxygen come from photosynthetic reactions through eating and breathing that undergo breaking to yield water and carbon dioxide, and waste along with ATP.
Therefore, option A. Glucose + oxygen → carbon dioxide + water + energy best represents cellular respiration.

The day of Josephine and Cora's campout had finally arrived. The two friends had been planning the campout for more than two weeks. They picked out a spot for the tent in Josephine's backyard. They chose the games they wanted to play. Now they were at the store with Josephine's dad buying camping food. "This campout is going to be perfect," Cora said as she dropped a bag of marshmallows into the cart. "We have the perfect tent, the perfect games, and the perfect food!"
Just then a loud clap of thunder sounded outside. The wind whipped as a bright flash filled the dark sky.
"But not the perfect weather," Cora moaned.
"That was thunder and that means rain. Rain means no camping," Josephine groaned.
"I guess we can stop shopping!" Cora snapped. She began taking food out of the cart.
As Josephine's father placed the food back in the cart, he told the girls not to give up on their campout. They paid for the food and went back to Josephine's house to wait out the storm.
At dinnertime the sky remained dark gray as the rain continued to pour down outside. The girls sat in silence while they ate. Cora looked out the window and said sadly, "I can't believe it's still raining. Our campout was supposed to be perfect."

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.
