Answer: The correct answer is option (b).

Explanation:

A cycle in science is defined as process or phenomena which reoccurs again after a certain interval of a time.

In a set of chemical reactions where reactant is regenerated as a product in the end. This regenerated reactant will again establish the same set of chemical reactions in a same the fashion continuously.

Krebs cycle: it is cycle which occurs during in cellular respiration which starts from acetyl-Co-A enzyme. In the end of cycle energy is released with regeneration of acetyl-Co-A enzyme which will further continue the cycle.

Calvin cycle: It is cycle which occurs in chloroplast during the process of photosynthesis which starts from carbon-dioxide. In the end sugar molecule is released with regeneration of carbon-dioxide molecule which will further continue the cycle.

Hence, Krebs cycle and Calvin cycle both are cycles of chemical reaction in which start over continually.

A large highway barrier is 1 meter wide, by 1 meter tall, by 2 meters long.
Romashka [77]

Answer:

when mass is  1×10⁴ Kg then density is 5 g/cm³.

when mass is 104 Kg then density is 5.2 × 10⁻² g/ cm³.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

mass = 1×10⁴ Kg

volume= w ×l× h = 1×2× 1 = 2 m³

density = ?

first of all we will convert the given volume meter cube to cm³:

we know that  

2×1000000 = 2 × 10⁶ cm³

Now we will convert the mass into gram.

1 Kg = 1000 g

1×10⁴ × 1000 = 1 ×10⁷ g

Now we will put the values in the formula,

d = m/v

d = 1 ×10⁷ g / 2×10⁶ cm³

d = 0.5 × 10¹ g/cm³

   or

d = 5 g/cm³

If mas is 104 Kg:

104 × 1000 = 104000 g

d= m/v

d = 104000 g / 2×10⁶ cm³

d= 52000 ×10⁻⁶ g/ cm³

d= 5.2 × 10⁻² g/ cm³

Briefly describe how the structure of each molecule differs
son4ous [18]

Answer:

A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
