Answer:
1. Independent variable- paper clips
Dependent variable- how far it will fly.
Control- mass of plane
Constant- type of plane
2. independent variable- using calculators
dependent variable- who will answer the questions faster
Control- the time the groups get done with the math problems
Constant- the math problems
3. Independent variable- Age of children
Dependent variable- the time it takes to complete the puzzle.
Constant- The type of puzzle
4. Independent variable- Amount of coffee grounds
Dependent variable- The taste of the coffee
Constants(3)- The same kind of coffee, same type of water, and the same perking time.
Explanation: The dependent variable depends on the independent variables change. For example: The amount of coffee grounds determine the taste of the coffee. The coffee grounds would be the independent variable because the dependent variable is the taste of the coffee, and the taste of the coffee determines on how much coffee grounds we use. Constants are the things that stay the same during the experiment. For example: We use the same brand of coffee throughout the experiment, so the brand of coffee is our constant. The controls are the things that do change. For example: The paper clips on the plane weighed the plane down more and more each experiment. So, the control would be the amount of paper clips used each test. The mass could also be a control in this experiment because the change in the paper clips changes the mass of the plane. I did this in 7th grade, and i am in 11th, so I know this is correct. I hope this helps you:)

Most other types of cells have the ability to replace damaged molecules and organelles. Red blood cells have a reduced capacity for repair and thus only survive for about four months. Construct an explanation based on the structure of red blood cells for why red blood cells are unable to repair damaged proteins.
Answer:
The red blood cells do not repair by themselves, that is why they must be destroyed in the spleen or rather phagocytosed, so that they are then newly formed in the spleen.
Red blood cells are unable to repair protein damage since one of these infleunctions is their anucleation.
Explanation:
The clearance of red blood cells is essential since the half-life of this cell is a few months, once these months have passed the red blood cell will not fulfill the function in the same way.
They are characterized by having a tetrahedral protein that is related to gases such as oxygen according to its partial pressures.
This protein called hemoglobin is responsible for transporting oxygen to the tissues and oxygenate them.

Answer:
ATP
Explanation:
Adenosine triphosphate (ATP) can be thought of as a cellular battery. In its high energy state (ATP), when it is charged, it can provide energy for cellular processes. It then loses a phosphate and enters a low energy state, when it is converted to adenosine diphosphate (ADP).
The energy in ATP is stored in the high-energy phosphate bond. ATP acts as a shuttle, delivering energy to areas where energy-consuming activities are taking place. It can quickly provide the energy for this process, and is then converted to ADP.

Answer:
I guess c...I'm on C.uayayayayay
Water conservation is the traditional and advanced practice of using water efficiently and reducing the wastage of water.
Water conservation is not a costly endeavor even though its environmentally beneficial.
Water conservation can be done as:
Only 1% of the Earth's water is available to humans for consumption, so the contamination of water should not be done. Water shortages have been predicted for nearly half of the states and some of them are facing severe water scarcity. Water conservation can be done free of cost, as doing rainwater harvesting, and also other processes can be applied to conserve water. The failure to conserve water will not lead to more contamination of water.Thus, the correct answer is Option C.

Millions of nonnative cattle in Australia produce a huge amount of dung for decades Australia has imported nonnative dung beetles to help clean up the dung which sentence best explains what would have happened if Australia had not imported the nonnative dung beetles
Answer:
Explanation:
The question is incomplete kindly find below the correct question.
In Australia, millions of nonnative cattle produce a huge amount of dung. For decades, Australia has imported nonnative dung beetles to help clean up the dung. Which sentence best explains why native Australian dung beetles were not doing the job?
A. Cow dung is not part of any native Australian species' niche.
B. Native Australian dung beetles lack a niche in Australia.
C. Cows have no known niche in Australia.
D. Decomposers lack a native niche in Australia.
Answer: B. Native Australian dung beetles lack a niche in Australia.
Explanation:
A niche is a place an organism occupies and the roll they play in an ecosystem. Because the dung beetles were nonnative and imported they have no niche in Australia compare to the Cow who have been settlers this makes it impossible for them to feed on the dungs because they are not use to the dung as source of feed and the dungs could not decompose because no activity was carried out on them.
This will make the cattle avoid feeding in the pasture due to accumulated dung but rather move far for pasture.
Answer:
Cow dung would have piled up in Australia

3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.
Answer:
I'm answering Q1: the major ways in which humans are damaging the environment is cutting down trees. trees are homes for other animals like birds and koalas and so much more I can't name. if you cut down a tree an animal loses its shelter, the animal doesn't have a shelter to stay, the animal dies, the animal dies we we have no food. Also trees are very much needed and very important for us humans. trees release oxygen when they use energy from sunlight to make glucose from carbon dioxide and water. also cutting trees adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide.
What force can stop gravity in a black hole?
Answer:
No force.
Explanation:
If the core is very massive (approximately 2.5 times more massive than the Sun), no known repulsive force inside a star can push back hard enough to prevent gravity from completely collapsing the core into a black hole.

Melted snow from the Sierra Nevada mountains and other mountain ranges is an important water source for much of California. Using evidence, explain why a lack of snow in the mountains could make drought cycles worse over time.
Answer:
DIS IS KARMA
Explanation:
:))))))))
Answer:
A lack of snow in the mountains could make drought cycles worse over time because of the water cycle.
Explanation:
When snow melts, it cycles into rivers, into lakes, and underground. Without this water, these resources may dry up more quickly in the summer. If water resources are too low, then people may need to use less water for personal use and agricultural use.
