Answer:
Results can be reproduced
Explanation:
An experiment is a test conducted to prove the validity of a hypothesis. The results of an experiment is used to either accept or reject a predicted claim called hypothesis.
As stated in this question, a scientific experiment has several characteristics including its falsifiability. The result of a good scientific experiment must be able to be REPRODUCED OR REPLICATED. This increases the chance of being correct and the claim accepted.

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.

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.

Angiosperms are such a successful group of plants because of how well they recruit animals for pollination and the diverse way they disperse their seeds. Describe two ways animals spread angiosperm pollen and two ways fruit is dispersed.
Animals can be very important to plant reproduction in two ways—spreading pollen and spreading seeds. Pollen contains a plant’s sperm.

Homeostasis means to maintain balance or equilibrium
True
False
Answer:
True.
Explanation:
Homeostasis is the process of maintaining balance inside your body.
Ex:
When you sweat, your body is trying to cool down your body temperature from being hot to cool.
When you eat food, the excess comes out as waste.
When you shiver, your body is trying to make you warm when you are cold.

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

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.
The molecule that is used as the energy currency (efficient storage of energy) is the blank molecule.
what goes in the blank
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.
Discuss how what you have learned about the respiratory system has caused you to see the environment around you differently. Are there specific activities or environments that you are more likely to avoid now? Explain why (or why not) your thinking about these activities or environments has changed.
Answer:
The respiratory system is directly connected to the external environment. More specifically, the gaseous environment around me can automatically find its way into the internal environment inside me.
The human respiratory system takes in air from the external environment. The purer the air is, the purer the content of its intake.
The system which keeps the lungs clean is found in the trachea which is lined with cells containing hair-like protrusions called cilia and also produces mucus and water droplets. The mucus and the cilia's activities combine to keep air passages hydrated and work together to trap dust, bacteria, and other foreign substances. An example of a foreign substance is heavy smoke from a building on fire. Other examples are cigarette smoke, heavy atmospheric dust such as is found in deserts. When these substances are inhaled, they can temporarily impede the efficiency of the cilia.
So it is important for one to avoid environments whose air is contaminated.
Because a contaminated environment translates to an impeded functioning of the respiratory system and a reduction in the quality of oxygen that reaches the bloodstream.
