Answer:

Option D, The work done by each force is negative

Explanation:

When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant , it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.

At which location in Earth’s interior does the top density continue to increase as thickness decreases? inner core outer core lo
kakasveta [241]

Answer: At the inner core of the earth interior, top density continue to increase as thickness decrease.

Explanation:

The Earth is the third plant from the sun and the fifth largest plant. It is the only planet that can harbor life, that have oxygen in the arthmosphere and oceans on the surface. The Earth have three main layer which are the core(the outer and inner core), the mantle and the crust. All the three layers support life existence. The earth inner core is the innermost geologic layer and it is hot and denser. It is a solid ball of 1,220 kilometers. The earth inner core has the highest density (12)than all other layers and it is less thicker than mantle and the crust. Density increase with depth because the pressure increases also.

Organic molecules derived from vitamins that act as helpers are called
AysviL [449]
Coenzymes

Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions. 

Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.
