Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.
Genetically modified can be stated as the foods which are derived from whose genetic material (DNA) has been modified in a way that does not occur naturally
<u>Explanation:</u>
<u>pros:</u>
- It takes less land for cultivation and it produces more food
- It can conserve energy soil and water resources

- It will use less water
- less use of pesticides
<u>cons:</u>
- Increased rate of allergic reaction
- It can spoil or pollute the others fields and stuffs

- Less nutritious
- chance for genetic changes
Reaching ...............via the SOMATIC nervous system.
The somatic nervous system is the part of the peripheral nervous system which is associated with associated with voluntary control of body parts.
The major functions of the somatic nervous system is voluntary movement of muscles and organs.
Energy changes forms from heat, to kenetic, to potential energy. However, the total energy is the atmosphere is conserved, meaning energy can only change forms, but cannot be produced.
