Answer:
Cell wall
Explanation:
The cell wall is the part of the bacterial cell is most involved in gram staining. This is because the two types of gram bacteria which are known as the gram positive and gram negative bacteria have different and unique cell wall constituents.
The gram positive bacteria have a cell wall composed of peptidoglycan while the gram negative bacteria have cell wall composed of a thin layer of peptidoglycan and an outer layer of lipopolysaccharide. They give different results when stained ; gram positive bacteria retains the crystal violet color of the reagent used while the gram negative bacteria gives a pale reddish color.
Instincts are the biologically determined, innate patterns of behavior.
Instincts are the intuitive feeling of a person towards a certain stimuli. These are inborn impulses. There are 6 basic human instincts. These are seeking, anger, fear, panic-grief, care, pleasure and play. Amongst all, seeking is considered to be the most powerful instinct.
Innate behavior is the habit that is present inside an organism by birth, may be genetically. No prior learning or experience is required for it. Examples of the same are: reflexes, taxis and kinesis, fixed action patterns and circadian rhythms. When a baby suckles after birth, it is an innate behavior.

The answer is the first group
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
A cell can only respond to signals from other cells, not from the physical environment. receptor activation. The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on: the presence of the appropriate receptors on the cells of the target tissue or organ.
