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.

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.

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)

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.

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.

Answer:

she is wrong , its c

Explanation:

The grass population would decrease. The snake population and hawk population would increase.

The correct answer is option C. . If you were to suddenly double the population of rabbits, the grass population would decrease due to overgrazing by the increased rabbit population.

As a result, the snake population and hawk population would increase due to the increased availability of prey. This is known as a trophic cascade, where changes in one trophic level affect the populations of other trophic levels in the food chain.

Option A and B are unlikely as doubling the population of rabbits would not necessarily cause the populations of the other three species to increase or decrease in a straightforward manner.

Option D is incorrect as there is no direct relationship between the rabbit population and the hawk population in this food chain.

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.

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
