ALL THE ANSWERS:

1) TRUE - Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O.

2) TRUE - Animal proteins, such as meat, eggs, and milk, are complete proteins, meaning they provide all of the essential amino acids our body needs.

3) FALSE - If talking about neutral lipids, they are soluble in organic solvents and are not soluble in water.

4) TRUE - Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid.

5) TRUE -DNA and RNA are both nucleic acids

6) TRUE - Sucrose is a disaccharide made up of 50% glucose and 50% fructose.

7) TRUE - It has numerous glucose units

8) TRUE -Some doctors may call that

9) FALSE - Keratin is completely insoluble in cold or hot water.

10) TRUE - Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid.

11) TRUE - Each heme group contains one iron atom, that can bind one oxygen molecule through ion-induced dipole forces.

12) TRUE - It has three parts

13) TRUE - DNA has a double-helix structure

14) FALSE - Triglycerides are lipid

15) FALSE - It’s debunked, the molecular structure of unsaturated fats makes them liquid at room temperature. Their fat molecules do not stack easily, so they cannot form a solid at this temperature.

HOPE THIS HELPS :)

Both retinal disparity and convergence increase as an object gets closer to the individual.
Gnom [1K]
That statement is true

Retinal disparity : space between your eyes that allow binocular vision to create depth perception

Retinal Convergence : Space between your eyes that signal visual moves to the retina

They both will increases as an object get closer to the individual, allowing them acknowledge and observe the existence of the object

Why does the density of a substance remain the same for different amount of the substance
tresset_1 [31]

Think of it this way: 
-- Any time you have something that means (some number) PER UNIT,
it doesn't matter how many units there are on the table or in the bucket,
because that amount doesn't change the (number) PER UNIT.

-- If oranges cost $1 PER POUND, it doesn't matter how many pounds
you buy, the whole bagful is still $1 PER POUND.

-- If a certain salad dressing has 40 calories PER Tablespoon, it doesn't
matter whether you eat a drop of it or drink the whole jar.  You still get
40 calories PER Tablespoon.

-- Density means '(mass) PER unit of volume'.  Whether you have a tiny
chip of the substance or a whole truckload of it, there's still the same
amount of mass IN EACH unit of volume.

A 15.0 kg crate, initially at rest, slides down a ramp 2.0 m long and inclined at an angle of 20.0° with the horizontal. Using t
Elis [28]

The component of the crate's weight that is parallel to the ramp is the only force that acts in the direction of the crate's displacement. This component has a magnitude of

<em>F</em> = <em>mg</em> sin(20.0°) = (15.0 kg) (9.81 m/s^2) sin(20.0°) ≈ 50.3 N

Then the work done by this force on the crate as it slides down the ramp is

<em>W</em> = <em>F d</em> = (50.3 N) (2.0 m) ≈ 101 J

The work-energy theorem says that the total work done on the crate is equal to the change in its kinetic energy. Since it starts at rest, its initial kinetic energy is 0, so

<em>W</em> = <em>K</em> = 1/2 <em>mv</em> ^2

Solve for <em>v</em> :

<em>v</em> = √(2<em>W</em>/<em>m</em>) = √(2 (101 J) / (2.0 m)) ≈ 10.0 m/s
