First off, this should be under bio not physics...

1) Dehydration synthesis. For proteins: When two single amino acids connect to form a larger dipeptide, the hydroxide group from one amino acid connects with a hydrogen from the other amino acid. This forms the biproduct of H2O, or water (The OH and H bond to form H2O). Dehydration synthesis DOES NOT only occur in proteins, it can occur in carbohydrates and other macromolecules as well.

2) Carbohydrates provide for short-term energy. They play a major role in cellular respiration.
Proteins serve many functions throughout your body. They can take the role of enzymes (speeding up and regulating reactions). There are also structural proteins that make up ligaments in your body. Finally, there are also defensive proteins, such as antibodies and signal proteins.
Lipids are more for long-term energy storage. Storing lipids is much more effective than storing carbohydrates. A single gram of lipids can store twice as much energy as a single gram of carbohydrates. Lipids (fats and oils) also serve to cushion your vital organs.

3) Cellulose and glycogen are usually very branched out. On the other hand, starch and sugars are usually unbranched; a single straight line.

If you found this helpful, please consider making it the brainliest answer! :)

1) I think the answer is polymerization but I'm not sure

2) Carbohydrates - provides energy for your body
<span>
</span>Proteins do a lot of work in cells and exist for the structure, function, and regulation of the body's tissues and organs

lipids - are the main storage system/compounds that store the energy in your body


3)  I'm not exactly sure on this question, but I can tell you that cellulose, glycogen, and starch are all polymers of glucose but the differences are the types of bonds that they hold and the isomer type. For example, glycogen are compounds created from alpha-glucose. Also cellulose is created in plants.

What do you mean by momentum?
Shtirlitz [24]
The answer to this question is that --- The momentum possessed by a body is generally defined as the product of its mass and velocity.

Momentum is a vector and it also has magnitude as it is the product of the multiplication of the mass and velocity.

What mass of silver (in grams) is solidified when 749 joules of heat are released by a sample of molten silver at its freezing p
Anastasy [175]

heat released Q = 749 joules

heat of fusion of silver L = 109 J/g

Here phase of silver is changing from liquid to solid

so temperature will remain same

all heat will be released due to its phase change

and in this case we use Q=mL

where m is the mass of silver in gram

Q= mL

749 = m * 109

m = 749/109

m = 6.87 gram

Proposed Exercise - Circular Movement
notka56 [123]

Answer:

ωB = 300 rad/s

ωC = 600 rad/s

Explanation:

The linear velocity of the belt is the same at pulley A as it is at pulley D.

vA = vD

ωA rA = ωD rD

ωD = (rA / rD) ωA

Pulley B has the same angular velocity as pulley D.

ωB = ωD

The linear velocity of the belt is the same at pulley B as it is at pulley C.

vB = vC

ωB rB = ωC rC

ωC = (rB / rC) ωB

Given:

ω₀A = 40 rad/s

αA = 20 rad/s²

t = 3 s

Find: ωA

ω = αt + ω₀

ωA = (20 rad/s²) (3 s) + 40 rad/s

ωA = 100 rad/s

ωD = (rA / rD) ωA = (75 mm / 25 mm) (100 rad/s) = 300 rad/s

ωB = ωD = 300 rad/s

ωC = (rB / rC) ωB = (100 mm / 50 mm) (300 rad/s) = 600 rad/s

A dolphin in seawater at a temperature of 25°C emits a sound wave directed toward the ocean floor 154 m below. How much time pas
Cerrena [4.2K]

Answer:

0.2s

Explanation:

SO for the dolphin to hear its echo, the sound wave must travel a distance twice as much as the displacement between the dolphin and the ocean floor. So d = 154 * 2 = 308 m

Since the speed of sound in ocean floor is v = 1533m/s we can find out the time by dividing the distance d by the speed of sound

t = d / v = 308 / 1533 = 0.2s
