Answer:
Your answer should be Parasitism.
Example:
A flea on a dog: The flea benefits by getting shelter, and the food it needs to survive, the dog is harmed by getting its blood taken and getting infections.
8. (F) Facilitated diffusion: For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins.
9. (S) Simple diffusion: While water molecules are polar, they are also very small. One fact not mentioned in the video is that some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size.
10. (S) Simple diffusion: Charged ions are traveling through a cell membrane with the concentration gradient.
11. (A) Active transport: Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells.
12.(F) Facilitated diffusion: At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell.
The above choices are made based on the basic definitions of active transport, facilitated diffusion and simple diffusion.
Active transport: The movement of the ions or molecules to a region having higher concentration across the membrane requiring the help of energy or enzymes is active transport.
Facilitated diffusion: This type of transport involves passive movement of the molecules or is a type of passive transport where the movement of the molecules takes place from higher to lower concentration region occurs with the aid of a carrier molecule such as a transport or carrier protein.
Simple diffusion: This process involves movement of ions or molecules from high concentration region to low concentration region through a semipermeable membrane.
Answer:
c) epidermis
Explanation:
The epidermis is the outmost layer of tissue.
Answer:
Creation of mid-ocean ridges, creation of new mountains, formation of earthquakes, and formation of volcanoes.
Explanation:
The convergent boundary plate tectonic comprises collisions between the continental and oceanic plates. The less dense and thinner oceanic plate gets overridden by the more denser and thicker continental plate. The ocean plate is forced down the mantle, and the event is called subduction.
The magma found in the mantle leads to melting of the subduction plates. The magma gets within the plates via pores. This magma plate turns buoyant and moves in an upward direction. The molten magma leads to volcanic eruptions along with earthquakes. The solidification of magma in the subduction zone leads to the formation of ocean ridges. The formation of mountains close to the continents takes place when the magma after the volcanic eruption gets cooled and solidifies.
