An electromagnetic wave can travel through anything - be it air, a solid material or vacuum. ... Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
For my opinion i think its A because lipid can dissolve in water.
Mitosis and meiosis
The statement is true. While mitosis's main function is to repair and grow, meiosis fulfills its function in reproduction, forming the egg and the sperm, the cells involved in the fecundation to form a new individual.
Answer:
D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
Explanation:
Active transport refers to the movement of molecules across biological membranes against a concentration gradient. Active transport can be divided into 1-primary active transport, which requires energy from the hydrolysis of adenosine triphosphate (ATP); and 2-secondary active transport, which requires an electrochemical gradient generated by pumping ions in/out of the cell. The case above described represent a type of secondary transport active because the movement of sodium (Na) ions is used as energy source to move glucose molecules against their concentration gradient.
Yes they technically are because plants were here before humans
