Answer:
HERE
Explanation:
The structure of the skin Is the biggest bone in our body and it protects our exoskeleton
Answer:
1. E.coli
2. Intestinal tract
Explanation:
E.coli bacteria are useful to humans when they live in the large intestine of humans. The large intestine is an important digestive structure as it is important for the reabsorption of the nutrients.
The E.coli living in the intestine use the available digested nutrients and synthesises the vitamin B and K which are absorbed and utilised by the human body.
Thus, E.coli and Intestinal tract is correct.
The answer would most likely be B, diffusion. Diffusion is the process of molecules going from an area of higher concentration of those particles (around Tammy) to an area of lower concentration (around Jim who is across the room), without the use of energy, as they are going with the concentration gradient (higher concentration to lower concentration). In this question, the molecules would be the molecules of Tammy's perfume. The area around her has a higher concentration of perfume particles, as she sprayed the perfume on herself. The area around Jim would be the area of lower concentration, as there are less molecules of perfume around him. Osmosis is the diffusion of water molecules from an area of higher water concentration to an area with a lower water concentration through a semi-permeable membrane. Active transport is the process of diffusion, however, it requires energy as the molecules go across their concentration gradient (from low concentration to high concentration). Facilitated diffusion is the process by which molecules go from a higher concentration to a lower concentration. However, the molecules go through a cell's membrane with the aid of proteins on the membrane. Therefore the answer would be diffusion.
