Which statement correctly describes the relationship between elements and compounds?
O A. Compounds contain fixed ratios of different elements.
B. Elements contain fixed ratios of different compounds.
C. Compounds contain variable ratios of different elements.
D. Elements contain variable ratios of different compounds.
Answer:
A. Compounds contain fixed ratios of different elements.
Explanation:
Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition.
Every compound has fixed ratios of different elements. The correct option is A.
What is an element?A substance that could not be converted into various components by any non-nuclear chemical process is referred to as an element.
Every compound has fixed ratios of different elements.
Thus, the correct option is A.

How do you think a computer virus compares to a real virus!
Answer: A computer virus compares to a real virus because they both take over whatever they're destroying. It copies itself and typically has a detrimental effect. And it can be caught without even knowing it!
A computer virus can self replicate just like a real virus.
-Hope this helped<3
Answer: They're both a mass attack.
Explanation:
They both mass attack a certain thing. Like a virus contracts only humans and basically living things. Computer viruses are, well, contracted to computers.

Prokaryotes are structurally simple organisms that have existed for over two billion years.
Which of the following are prokaryotes?
Choose 1 answer:
(Choice A)
A
Animals
(Choice B)
B
Bacteria
(Choice C)
C
Plants

Answer:
choice B
Explanation:
Bacteria are super small single-celled organisms that thrive in many environments.
Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.
What are Prokaryotes?A prokaryote is defined as a single-celled organism that lacks a nucleus and other membrane-bound organelles. Prokaryotes were classified within the kingdom Prokaryota.
Prokaryotic cells are described as single-celled microorganisms that are the earliest known on Earth which include bacteria and archaea. Photosynthetic prokaryotes include cyanobacteria that photosynthesize that have a single cell membrane and, therefore, all reactions occur within the cytoplasm.
Bacteria are examples of the prokaryotic cell type, some example is E. coli.
Thus, Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

The measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane is called...
A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty
The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.
What is osmolarity of a solution?Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.
According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.
Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.
From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
Therefore, osmolarity measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.

7,351 round to nearest hundred
Answer:
7 400
Explanation:
7, 351
7 is the thousands
3 is the hundreds
5 is the tens
1 is the unit
to round of to the nearest hundred look at both the hundreds value and the tens value.
since the tens value is 5 , this means the hundreds value increases by 1.
therefore 3 turns into 4
7351 to the nearest hundred is 7400

What's wrong with this ecological pyramid?
Answer:
The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid
Explanation:
The sun is the ultimate source of energy that provides energy to the producers. The producers use the light energy to synthesize the chemical compound. The energy from the producers is transferred to the primary consumers and their energy is transferred to the next levels. The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.

Answer:
(See Below)
Explanation:
[1] Magma comes out of the rift valley.
[2] Magma cools to rock and hardens.
[3] Rock is pushed away as new rock is formed at MOR (Mid Ocean Ridges)
[4] Oceanic crust and continental crust meet at the trench.
[5] Oceanic crust bends down under the continental crust.
[6] Gravity pulls rock towards mantle.
[7] Rock melts to mantle.
