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.

Which two processes help animals maintain body temperature?
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:
Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Endotherms can alter metabolic heat production to maintain body temperature using both shivering and non-shivering thermogensises.

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.

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.
Which of the following accurately describes the word equation for cellular respiration? *
A.) Glucose + oxygen --------> carbon dioxide + water + energy (ATP)
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.
