Answer:
B
Explanation:
The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.
Answer:
Fermentation
Explanation:
To find the correct answer, we will review over the definition of each answer choice.
Photosystem I is A membrane in a plant that produces high levels energy from light
Based on the definition, we can conclude that photosystem 1 is not the correct answer.
ATP Synthase are molecules that create ATP
We know that this answer choice is also not correct.
Glycolysis is the process of breaking down glucose to create energy.
Based on the definition provided we know that this answer choice is also incorrect
Fermentation is the process of lactic acid being formed when there is not enough oxygen present for cellular respiration to take place.
Therefore, fermentation is the correct term we are looking for.
Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
