Explanation:
They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

Explanation:
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
Over the years, bacteria have become less sensitive to antibiotics used for medicinal and sanitation purposes. This lack of sensitivity is termed antibiotic resistance. How is antibiotic resistance an adaptation?
A.
Antibiotic resistance has caused antibiotics to become more specialized, thus adapting the antibiotics to particular bacteria species.
B.
The trait giving bacteria antibiotic resistance has reproductively isolated groups of bacteria.
C.
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
D.
Antibiotic resistance makes it more difficult for bacteria to infect hosts, thus is a selective advantage for the host.

There are three types of plate boundary such as Constructive, destructive and transform plate boundary. The primary landform in the Transform boundary are faults which is caused by the Earthquakes. Many transform boundary landforms are in the ocean floor which is responsible for the island formation. Fault is found due to the two process such as Ridge push and ridge pull. Transform boundary neither creates and nor destroys any land in the region.

Explanation:
I am able to fill a glass of water to the top and it does not overflow…which property of water allows this to happen
Answer: surface tension
Explanation:
Answer:
When we fill the glass with water, we notice right away that it can go over the brim of the glass without spilling. This is because of surface tension. Surface tension holds the water together and acts against what would normally cause the water to fall – gravity – because each molecule of water is attracted to the other water molecules around it.
Explanation:
extra facts Water molecules are attracted to each other and is why you can fill a glass and as it gets to the top it will stay together to a certain point. However that stick together ability is pretty mild so when gravitational forces take effect the bonds are broken and it flows down the sides of the glass. Unfortunately, the attraction between the water molecules is only so strong. As we add coins, the amount of water spilling over the edges is getting larger and larger until the water just can’t take it anymore! Gravity is pulling on too many of the molecules for their attraction to keep them up, and the water spills down the side of the glass.What to Do. Place the glass on the saucer and fill the glass of water all the way to the brim. You’ll notice that the water hangs slightly over the top of the glass but doesn’t spill out just yet. Now, add the coins one at a time to the glass of water, dropping them in rim-first (not face down).

to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a __________.
To allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.
The sheath is a fibrous but at the same time serous element that is composed of a viscous liquid called the synovium, which is designed in order to allow the tendons to move with the bones.
The function of the sheaths is to allow a correct sliding between the tendon where it meets the bone through which it passes.
The importance of sheaths for the biomechanics of movements is that if they were not located in the tendons, these tissues would wear out very easily, thus causing injuries such as tenosynovitis.
The best known synovial sheaths are those of the flexor apparatus of the hand, that is to say to the internal and external digitocarpal, in the fibrous band of the foot, and in the long tendon of the biceps muscle.
Therefore, we can conclude that to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.
