Answer:
red blood cells or formed in the red bone marrow of bones
Answer:
The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body.
Answer:A food chain shows what eats what in a particular habitat. It shows the flow of energy and materials from one organism to the next, beginning with a producer . ... The arrows between each organism in the chain always point in the direction of energy flow from the food to the feeder.
Explanation:
Answer: c) from an area with a high concentration of water to one of lower concentration
Explanation:
Microscopically, we can interpret osmosis as the passage of water through holes in the membrane. These holes are small enough to allow water to pass through, but not to the ions that carry a layer of hydration, that is, a layer of water molecules around them. Water flows through the membrane in both directions. However, the occurrence of osmosis indicates that the flow is more intense in the direction of the less concentrated medium to the more concentrated. Thus, there is an effective flow of water in one of the senses, called osmosis, from an area with a high concentration of water to one of lower concentration.
Answer: Differences in osmotic concentrations
Explanation: With solvent particles flowing into the cell, it means the concentration outside of the cell is higher and with initial volume less than 50%, then that within the cell is lower. This results in an osmotic gradient, allowing particles in areas of higher concentration (outside the cell) to flow into the cell, an area of lower concentration.
