1) The process of cellular respiration takes place in the mitrochondria.
2) The process of photosynthesis takes place in the chloroplasts. Only plant cells and the cells of autotrophic protists and some bacteria undergo this process.
3) Phospholipids are lipids that consist of glycerol joined to two fatty acids and a phosphate group, which gives this molecule two nonpolar hydrophobic tails and a polar hydrophilic head. Phospholipids form bilayers that are used to make up biological membranes.
4)While there are definitely many more than 4 important molecules, I'm assuming the ones you are looking for are carbohydrates, proteins, Nucleic acids, and lipids.
5)A molecule is made up of two or more atoms held together by covalent bonds, whereas a compound is a substance containing two or more elements in a fixed ratio. Both molecules and compounds are made up of atoms/elements, however, compounds MUST be made up of two different kinds of elements, while molecules could consist of the same kind.

Hope this helps! :)

An angle measures 18 more than the angle of its complementary what is the measure of each angle

Debora [2.8K]

Answer:

Step-by-step explanation:

complementary angles, when added, equal 90 degrees

so if 1 angle is x, then the other angle, its complement, is 90 - x.

x - 18 = 90 - x

x + x = 90 + 18

2x = 108

x = 108/2

x = 54

90 - x = 90 - 54 = 36

so one angle is 54 and its compliment is 36

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.

A buoy starts at a height of 0 in relation to sea level and then goes up. Its maximum displacement in either direction is 6 feet

svet-max [94.6K]

Answer:

$h=6*sin(\frac{2\pi }{8}t)$

Step-by-step explanation:

Since the buoy is going up and down, its motion is oscillatory, and therefore, it can be described by a trigonometric function.

The buoy starts at height of 0 in relation to the sea level, which means at time $t=0$ , $h=0$ , this tells us that trigonometric function modeling the buoy must be the sine function since for

$h=A*sin(wt)$ , at $t=0$ , $h=0$ .

The maximum displacement of the buoy in either direction is 6 feet, this means we have

$h=6*sin(wt)$

now we need to figure out $w$ .

The time it takes the buoy to get from its lowest point to its highest point is 4 seconds, that means the period $T$ of oscillation is $2*4=8$ seconds. The buoy returns to to the same place after one period, this means if the buoy started from 0, it will return to 0 after 8 seconds; therefore, from $h=6*sin(wt)$ the we have:
