Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.

Answer:
The correct answer is E. Answer choices a, b, and c.
Explanation:
There can be many causes for a gram standard culture to appear red like if we use decolorizer for a long time then even the gram-positive cells present in the culture will lose their dye and become decolorized. Then they appear red after counterstaining with safranin.
If a gram-positive culture is older than 24 hours they can appear red because after 24 hours because the peptidoglycan starts degenerating and fails to persist crystal violet it their walls.
Iodine makes complex with crystal violet which is retained by peptidoglycan present in gram-positive cell wall. So when we forgot to add iodine crystal violet will not be retained and cells will appear pink.
Thus, the correct answer is E. Answer choices a, b, and c.
Answer:
The answer is 4
Explanation:
The answer is 4 because we are talking about pairs of homologous chromosomes and there two copies are held together and they are located in the centromere.
Synapsis is two homologous chromosomes pairing. During the event of <em>meiosis </em>homologous chromosomes are being pared but then also separated because of reducing the genetic content of the resulting haploid cells.
