Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
The term that best completes the given statement above is the word ATTENUATED. A method of producing an attenuated vaccine is through genetic manipulation of a microbe to remove one or more virulence factors. The purpose of creating attenuated vaccines is to reduce the effect of a microorganism to the body. Once the body is exposed to the said disease, it will not experience a dreadful effect done by the microorganism.
Answer:
light-dependent reaction
Explanation:
photosynthesis converts reactant carbon dioxide to product glucose
Answer:Although VO2 max is a good marker of fitness, it does present some downfalls. You can't really get an accurate measure .
Explanation:So, one way to determine your max VO2 pace is to warm up, then run for 8 minutes at the maximum intensity level you can sustain for 8 minutes. If, for simplicity's sake, you ran one mile, then your VO2 max training pace is 8 minutes/mile.
Answer:
I don't remember much, but I'll try my best.
Explanation:
Over time, sediments rocks pile up to form horizontal layers of sedimentary rocks. The bottom layer of rock forms first, which means it's the oldest. This would mean that while you can't be sure when each layer of sediments formed, each layer is younger than the one below it.
