Answer:
Duralumin is an aluminium alloy.
Explanation:
Duralumin is a kind of mineral.
What is Duralumin?There isn't a single chemical composition for duralumin because it is an alloy of copper, magnesium, manganese, as well as aluminum that can change based on its intended application. 4.4 percent copper, 1.5 percent magnesium, 0.6 percent manganese, and 93.5 percent aluminum make up a typical alloy.
What is mineral?A mineral would be an inorganic solid that forms in nature and have an organized atomic structure and a known chemical composition. Even while it may seem like a mouthful, if you break it down, it becomes clearer. Minerals have been created naturally. They are not human-made. They have inorganic, minerals.
Another of the earliest varieties of age-hardenable aluminum alloys goes by the brand name Duralumin. The word is a mix of aluminum and Dürener.

Two negatively charged objects exert a force on each other. Describe the force between the objects, and describe two ways to increase the force between them.
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Repulsion between chargesForce of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another.
Effect of distance on forceIf we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.

Which action would most likely increase the greenhouse effect?
A. Encourage people to conserve power
B. Use more nuclear power plants
C. Stop cutting trees in the Amazon forest
D. Burn more oil for heating homes
Answer:
D. Burn more oil for heating homes
Explanation:
Encouraging people to conserve power would help weaken the greenhouse effect, not increase it. Stopping cutting down the trees in the Amazon forest would also heavily help weaken the greenhouse and not increase it. And unlike the others, using more nuclear power plants wont affect the greenhouse atfect but instead affect our air quality. Our problem is that burning coal, oil, and gas produces carbon dioxide, which adds to the supply already in the atmosphere, increasing the greenhouse effect and thereby increasing the temperature of the Earth so therefore its D.
BURN MORE OIL FOR HEATING HOMES
If you know what the greenhouse effect is, you'd easily know the answer. I'm not going to explain because the other user already did that very well. All I'm going to say is I took this biology a p e x quiz today and decided to share my answer with you guys (it's correct btw).

The greatest extent of membrane-bound compartmentalization occurs in Group of answer choices archeaa bacteria eukaryotes viruses
Answer:
The correct answer is - eukaryotes.
Explanation:
Eukaryotic organisms are the organisms that have membrane-bound organelles or compartments in their cells that play different types of roles in the cell such as assisting in cellular respiration, photosynthesis, packaging and modifying the proteins, and also helps in transporting them.
In archaea, bacteria and viruses lack true membrane-bound organelles in their cells and found very limited cell organelles like ribosomes and others but no membrane-bound organelles at extent of eukaryotic cells.

Do you think animals pollinate flowers and disperse seeds on purpose or by accident?
Answer:
Animals most likely pollinate by accident.
Explanation:
Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily mean to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

Enzymes are changed by the reaction and can be reused.
D
Enzymes are specific to the substrate to which they bind and can be reused.
E
All enzymes act on different reactions and by increasing the rate of the reaction.

D :elevation above sea level
Answer is A : variety of living things
Explanation:
Biodiversity, also known as biological diversity is a term used to describe the variety of life on earth across different levels of biological groups. Some scientists have come up with some studies to show that there are over 10,000 species of birds, 200,000 species of flowering plants and almost one million species of insects in the world.
Any environment that is said to have attained the highest level of biological diversity is one that has the most variety of these species of birds, flowering plants and insects.

Which of the following is a community?
A. All of the nonliving things that make the lake inhabitable O
B. All of the fish, bacteria, and mammals that live in a lake
C. All of the living and nonliving things that interact in and around a lake
D. All of the trout that live in a lake
Answer:
B. All of the fish, bacteria, and mammals that live in a lake
Explanation:
In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.
Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.
Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".
Apossible explanation of or answer to a scientific question that is based on prior knowledge or research and is testable is called a
O law.
O hypothesis.
O theory.
O experiment.
Answer:
The correct answer is hypothesis.
Explanation:
The hypothesis can be defined as a provisional prediction or explanation (as long as it is not tested) of the relationship between 2 or more variables. Thus, the problem-question precedes the hypothesis-answer which, in turn, derives from the objective (s) of the research.The hypothesis, as a formulation that raises a presumed relationship, can be expressed in the form of a proposition, conjecture , assumption, idea or argument that is temporarily accepted to explain certain facts.
