Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
Answer:
False
"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
Explanation:
The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.
ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
E because i looked on quizlet idk look up the answer sorry
<span>Substances can move into and out of cells through the cell membrane. The three main types of movement are diffusion, osmosis and active transport.</span>
so you’d need to find the amount of gallons your family uses in 11 minutes and subtract 73000 from that number
i used the same formula, came up with 80300 gallons a year, and subtracted 73000 from it to get
7300 gallons are saved by reducing showering time by one minute
