A tea bag in a cup of hot water can be a simple model of a cell. Water moves into the tea bag and substances in the tea leaves move out through a thin layer of material. What does the thin material that holds the tea leaves represent?
Answers
Answer:
It represents a partially permeable membrane
Explanation:
As the water is added to the teabag it causes the tea leaves to move and triggers diffusion of the leaves. ... The addition of heat (from the hot water) to the tea bag causes its molecules to move much faster than at room temperature
Answer:
The cell membrane

Which part of the wave does the arrow point to?
A. Rarefaction
B. Crest
C. Frequency
D. Trough
Help me ASAP please
Answers
Answer:
B
Explanation:
It was the correct answer when I answered it
The part of the wave that the arrow is pointing to is the crest.
Wave is defined as a disturbance that travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself.The given diagram is a waveform. The waveform consists of a crest and a trough. The trough is the minimum amplitude of the waveform while the crest is the maximum amplitude of the waveform From the graph, the red dots are the crest of the graph while the blue dots are the trough.Hence we can conclude that the part of the wave that the arrow is pointing to is the crest.

Which conclusion about the chemical reactivity of these elements is valid? Boron is the most reactive because it has the most protons. Fluorine is the most reactive because it has 7 electrons in the outer shell. Silicon is the most reactive because it has an equal number of protons and neutrons. Gallium is the most reactive because it has many more neutrons than protons.
Answers
Answer:
Fluorine is the most reactive because it has 7 electrons in the outer shell. The conclusion of this element's chemical reactivity is valid .
Explanation:
Among all the given elements - Boron ,Fluorine , Silicon and Gallium , Fluorine is the most reactive element because it has 7 electrons in the outer shell. It has a very small size and only requires one electron to get into a stable configuration with that of noble gases. Thus, to reach that stable state, they react spontaneously with elements, leading to its high reactivity.
Therefore, most reactive elements are in the halogen band, and none of the other three elements called Boron, Silicon and Gallium belong to the halogen group.
Hence, the correct answer is B (fluorine is the most reactive because it has 7 electrons in the outer shell).

An atom has 8 protons, 9 Neutrons, and 10 electrons. What is the mass number?
Answers
Answer:
17
Explanation:
Mass number = # of protons + # of neutrons
Mass number is calculated using ONLY protons and neutrons. Electrons are not in the count.
Thus, we simply add them together: 8 + 9 = 17
This element is Oxygen - 17.

does sodium chloride retain any characteristic of sodium or chlorine?
Answers
Answer:
When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative. Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond.
