A group of students investigated how the salt content of water affects a plant that
lives in an aquatic ecosystem. On one slide, the students placed a piece of a leaf of
an aquatic plant and then added a drop of tap water. On a second slide, they placed
a piece of the same leaf and then added a drop of 10% salt solution. The students
observed both leaf pieces with a microscope. They repeated the process three times.
The table below summarizes their findings.

If humans accidentally release an herbicide, a chemical that kills plants, into the ponds, what impact would this have on the amounts of carbon the ponds could remove from the surrounding environment?
A.The amounts of carbon that the ponds could remove would decrease because there are less plants to cycle matter.
B. The amounts of carbon that the ponds could remove would increase because there is more area to cycle matter.
C. The amounts of carbon that the ponds could remove would increase because the plants decompose underwater.
D. The amounts of carbon that the ponds could remove would decrease because the plants retain strong roots.
What is the relationship between respiration and cellular respiration?
What is the difference between a partial blockage and an obstruction blockage?
What is the first aid for choking?
respiration is when you breath and cellular respiration involves taking the cells from when you breathe and turning it into chemical energy.
partial blockage can be cause by cancer within the bowel area or inflammation within the bowel area. obstruction blockage is caused by tissue compressed in the gut.
for first aid, you turn the individual on their back and deliver 5 back slaps between their shoulder blades, then do 5 chest thrusts.
The strength of an acid or a base depends on the degree of ionization in water

Which statement best describes the purpose of Earth's spheres?
They work together as open systems to cycle matter through ecosystems.
They work independently as closed systems to cycle matter through ecosystems.
They work together as open systems to move matter to living and nonliving parts of Earth.
They work independently as closed systems to move nutrients to living and nonliving parts of Earth.
Answer:
and they work together to drive the processes of the planet.
Explanation:
Earth has four 'spheres,' called the geosphere, hydrosphere, biosphere and atmosphere. These spheres each have unique properties and features, but they are not isolated on Earth, and they work together to drive the processes of the planet.
They work together as open systems to cycle matter through ecosystems. This statement best describes the purpose of Earth's spheres.
What are earths spheres?Lithosphere encompasses the entire solid land of the planet's crust, as well as the semi-solid land beneath it and even the molten core.Hydrosphere is made up of all of the planet's water, which comes in solid, liquid, and gaseous forms. Water comes down to the Earth's surface as precipitation from the atmosphere, rivers and streams along the surface, and groundwater beneath the surface. The majority of the world's freshwater, on the other hand, is frozen.Biosphere is made up of all the living things on the earth. This sphere contains all of the Earth's bacteria, plants, and animals. Living beings establish ecological communities in the biosphere based on their physical surroundings. Biomes are the names given to these types of communities.Deserts, grasslands, and tropical rainforests are just a few of the biomes found inside the biosphere.Atmosphere is made up of all of the air in the Earth's system.The biosphere's organisms are shielded from the sun's UV radiation by the upper atmosphere. It absorbs and emits heat as well. Weather occurs in this sphere as well.
These spheres interact via affecting one another, as well as through biogeochemical cycles and other natural phenomena that each of these spheres influences and causes.

Explain how water is used to create electricity.
Answer:
Explanation:Flowing water creates energy that can be captured and turned into electricity.The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Answer:
Water can be used in a lot of ways, let say that you have a big paddle by a raging river next to you to power your home, this paddle can keeping continuously moving to power that home based off how much that river is going. This is one way that water can be used to make electricity. Hope this helps, Merry Christmas, and have a nice day!

Write a paragraph explaining the function of a cell wall and cell membrane and why plants have cell walls and animal cells do not.
plssssssssssssssssssssssss a good paragraph with good vocabulary
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.

What is the relationship between respiration and cellular respiration?
Answer:
Through a chemical process called cellular respiration. As you know, respiration is the process of breathing. Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the oxygen your cells need for cellular respiration.

All cells contain two proteins called actin and myosin? True or false
Answer: i think its true
Explanation:
True that all eukaryotic cell i.e. muscle cells. contains actin and myosin protein .
What are actin and myosin protein?Actin filaments are responsible for a variety of cell motions, generally in conjunction with myosin. Myosin is a molecular motor prototype—a protein that transfers chemical energy in the form of ATP into mechanical energy, allowing it to generate force and movement. Muscle contraction is the most noticeable type of such movement, and it has served as a model for studying actin-myosin interactions and myosin motor activity. Actin and myosin interactions, on the other hand, are essential for not just muscle contraction but also a range of non muscle cell motions, including cell division, making them important in cell biology.Actin is a protein found in all eukaryotic cells. Actin filaments move along filaments of another protein called myosin to cause cells to contract. It was initially found in skeletal muscle. Actin filaments are less structured in non muscle cells, and myosin is considerably less prominent.Hence, the given statement is true.

What
factors can be used to identify
prokaryotes?
Answer:
Prokaryotes are highly distinguished from Eukaryotes, mainly on the basis of their nucleus type. As the word itself suggest that Pro means Primitive and Karyon means Nucleus, while Eu means Specialized and Karyon means Nucleus. Hence, Eukaryotes are more equipped than Prokaryotes. Prokaryotes are mainly found between 1-10 µ and Eukaryotes between 5-100 µ. Prokaryotes mainly have a poorly defined nuclear region with only nucleic acids called a Nucleoid and lack a nuclear membrane too. On the contrary, Eukaryotes have a well defined nucleus with a clear nuclear membrane. Also, The being primitive, prokaryotes have one strand of chromosomes while Eukaryotes have many (46). Prokaryotes also lack a lot of cell organalls. The ribosomes in prokaryotes and eukaryotes are 70's and 80's respectively. Also, photosynthetic prokaryotes have membranous vesicles for synthesis food, unlike Eukaryotic Plants that perform it with Chlorophyll.

What renewable energy source do you think would be best to develop first.
There is no right or wrong answer
In at least 3 sentences, please.
I believe solar power is a renewable energy source that should develop first. This is because as of right now, scientists know that they aren't as efficient as they could be. These panels are currently growing cheaper as production capabilities increases but the panels are going to rarely be able to produce efficiently due to weather conditions. If more money gets added to the research and development of this technology, these panels will become more efficient, thus making more clean energy.
