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 :)

What is the slope of the line if the rise of a line on a distance versus-time graph is 900 meters and the run is 3 minutes?
Alexandra [31]
600/3 = 200
the slope is 200m/min
 
OR

600/ (3/60) =
600 x 60/3 =
600 x 20 = 12,000 meters per hour

A bag of ice cubes absorbs 149,000 J of heat, which causes its temperature to increase by 5.23 degrees celsius. what is the mass
Dima020 [189]

Answer:

14.3kg

Explanation:

Given parameters:

Quantity of heat = 149000J

Change in temperature = 5.23°C

specific heat of the ice = 2000J/kg°C

Unknown:

Mass of the ice in the bag = ?

Solution:

The heat capacity of a substance is given as:

            H = m c Ф

H is the heat capacity

m is the mass

c is the specific heat

Ф is the temperature change;

  since m is the unknown, we make it the subject of the expression;

                    m = H/ mФ

                  m = \frac{149000}{2000 x 5.23}  = 14.3kg

The inner planets formed:
Ivan

Answer:

a. by collisions and mergers of planetesimals.

Explanation:

Inner planets are planets within 1.5 AU distance from the sun. These are called terrestrial planets because they are somewhat similar to Earth, mainly made of rocks.

The main ingredient of these planets are solar nebula and interstellar dust condensation of which leads to formation of small rock particles. These particles come close to each other under in the influence of gravity and other forces. As the mass of the particles increase they form planetesimals, these planetesimals eventually merge to form planets.
