Why are there so many earthquakes in califonia?
Answer:
The earthquakes of California are caused by the movement of huge blocks of the earth's crust- the Pacific and North American plates. Over time, these faults produce about half of the significant earthquakes of our region, as well as many minor earthquakes.
Answer:
The level of seismic activity is due to North Carolina's present upon a passive not active continental margin unlike West Coast regions which experiment frequent earthquakes along known and active Falls owns all of the known facts Exposed on the surface North Carolina are ancient and Interactive.

why is it advantageous for cells to switch to anaerobic fermentation in the absence of oxygen
[tex]\huge \mathbf{ \colorbox{black}{ \color{white}{Hello!}}} \boxed{♡} \Huge{►}[/tex]
How cells extract energy from glucose in the absence of oxygen. In yeast, anaerobic reactions produce alcohol, while in your muscles, they form lactic acid.
it is advantageous for cells to switch to anaerobic fermentation in the absence of oxygen because Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.
What is anaerobic fermentation?
Generally, Once the oxygen is removed from the fermentation vessel and replaced with N2, CO2, etc of the fermentation, anaerobic fermentation begins.
In conclusion, Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.

which type of microscopy allows us to clearly view the internal contents of cell structures smaller than 200 nm?
Because the cell structures are so small, to clearly view them, requires a microscope that has a higher power of magnification than light microscopes can prove. This is usually an Electron Microscope.
Electron microscopy (EM) is a technique used to obtain high-resolution images of biological and non-biological specimens. It is often used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes. (UMass Chan Med School Website)

what is the last structure of the air passageway in your lungs
Answer:
Bronchioles
Explanation:
You inhale through your nose and the air is filtered. It goes down the pharynx. It goes through the larynx. A "door" called the epiglottis opens during breathing. Then it enters the trachea. (windpipe) It goes through the bronchus. The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the ________. (I bet you can guess because you're so smart!) They're surrounded by capillaries that connect the pulmonary arteries and veins. This enables the transfer of oxygen and carbon dioxide.

suppose you and a friend are making iced tea using identical glasses. You both use the same amount of water, and the water temperature is the same in both glasses. Explain how you can tell who added more ice tea mix to the glass.
Answer:
Iced-Tea Problem
220 g of 35˚C tea (water) is poured over 250 g of -10˚C ice.
What happens...
The warm water (tea) will cool down to 0˚C. As it cools the ice will heat up to 0˚C and then start to melt.
There is plenty of ice however and only a portion of it will melt. Find the amount of ice that melts into water
and you’ll know the final composition and even the dilution factor on the tea.
Cool tea water down to 0˚C
4.184 J/g˚C · 220 g · 35˚C = 32216.8 J removed to cool tea to 0˚C
Warm ice up to 0˚C
2.09 J/g˚C · 250 g · 10˚C = 5225 J to heat ice up to 0˚C
This heat comes from the cooling water, so substract this amount off the total above
32216.8 - 5225 = 26991.8 J of heat that will MELT the ice
mass of ice melted = 26991.8 / 334 = 80.8 g of ice melted
220 g + 80.8 = 300.8 g of water
250 g - 80.8 = 169.2 g of ice
final mixture for
my glass of iced
tea all at 0˚C
220.0 g original tea
300.8 g final tea
The dilution factor is simply the original volume
over the final volume (or masses here ). = .731 or 73.1%
of the original
concentration
If I’m going to get a dilution of 73.1%, I should
compensate by mixing my tea in 26.9% LESS
volume than the directions state. So I will not dilute
the tea to 2 quarts (64 oz), but rather to 1.462
quarts (46.8 oz).
It’s hot and I want a glass of iced tea as soon as possible. The directions for my tea say to boil some water,
add 2 tea bags (these are the big bags), steep for 4-5 minutes, then add enough water to make 2 quarts which
turns out to be a pitcher of tea. However, if I make this tea the exact concentration I want now, when I pour
it over ice the ice will melt (because the tea will still be quite warm) and my tea will be too dilute. So I
calculate how much stronger I should make the tea KNOWING I will pour the warm tea over ice to make
my glass of iced tea.
(a). What is the final temperature and composition of the glass of iced-tea?
(b). What will be the concentration of the tea relative to the original concentration?
(c). How concentrated should I mix the tea knowing that it will be diluted when
poured over the ice?
(a)
(c)
(b)
only 73.1% of the full
amount to compensate
for dilution

what is the name used to refer to the clogged xylem tissue?
The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.
What is xylem?Xylem has been defined as the vascular bundle which has been used to transport water and other minerals from the root part to other parts of the plant. The main function of the xylem and phloem is to transport water and minerals from root to other parts of the plant.
The last common ancestor of the gymnosperms and angiosperms possessed the same characters such as the pollen, seeds, and the vascular tissue.The gymnosperms are a group of plant that are known as seed- producing plants such as Ginkgo, gnetophytes, cycads etc.
Angiosperms has been the plant that produces flowers and having seeds enclosed within their fruit. Gymnosperms have no production of flowers and fruits and they contain bare seeds on the surface of their leaves.
Therefore, The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.
