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.

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 did Cora mean when she said, "This campout is going to be perfect"?
A) Cora's parents' house was the best place to host a campout.
B) Cora planned the campout to bond with her perfect friend, Josephine.
C) They made a lot of plans and collected a lot of stuff for camping.

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.
Therefore, You notice in your mom's garden there are lots of differences in the zinnias there. These zinnias so different because the zinnia plants received different inherited information. Thus, option D is correct.

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.

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.

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.
