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 :)

Give two examples of energy being transformed from one type to another
GaryK [48]

Answer:

Explanation:

For example, an ice cube has heat energy and so does a glass of lemonade. If you put the ice in the lemonade, the lemonade (which is warmer) will transfer some of its heat energy to the ice.

Estimate the number of atoms in 1 cm^3 of a solid
dexar [7]
Avogadro's number: 6.02 x 10^23 atoms is present in 1mol of a solid (i.e. 22, 400 cm3)

Hence, in 1 cm3, 6.02 x 10^23 /22400 atoms is present = 2 x 10 ^ 19 atoms.

A 25-kg child sits at the top of a 4-meter slide. After sliding down, the child is traveling at 5 m/s. How much PE does he start
Semmy [17]

Daniddmelo says it right there, don't know why he got reported.

The potential energy (PE) is mass x height x gravity. So it would be 25 kg x 4  m x 9.8 = 980 joules. The child starts out with 980 joules of potential energy. The kinetic energy (KE) is (1/2) x mass x velocity squared. KE = (1/2) x 25 kg x 5 m/s2 = 312.5 joules. So he ends with 312.5 joules of kinetic energy. The Energy lost to friction =  PE - KE. 980- 312.5 = 667.5 joules of energy lost to friction.

Please don't just copy and paste, and thank you Dan cause you practically did it I just... elaborated more? I dunno.

A ball is thrown into the air with a vertical velocity of 50 m/s and a horizontal
daser333 [38]

\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Projectile Motion.

Since, here given that, vertical velocity= 50m/s

we know that u*sin(theta) = vertical velocity

so the time taken to reach the maximum height or the time of Ascent is equal to

T = Usin(theta) ÷ g, here g = 9.8 m/s^2

so we get as,

T = 50/9.8

T = 5.10 seconds

thus the time taken to reach max height is 5.10 seconds.
