Answer:
-100
Explanation:
If the total water potential in the soil around a plant root were -50 kPa, water would move from the soil into the root if the water potential inside the root cells were -100 kPa.
The water potential of a substance represents the measure of potential energy in water molecules in a system as compared to that of pure water. It is also a measure of the tendency of water to move from one region to another.
<em>Usually, water will move from the region of high water potential to the region of low water potential. Hence, for water to move from the soil into the root, the root must have a lower water potential than the soil.</em>
The soil had -50 kPa water potential, hence the only option that is lower than -50 kPa is -100.
The correct answer is -100 kPa.
Answer:
yes negative effects outweigh the positive because of there isn't much positive and all the components withing the ship may pollute the ocean and lead to worst case scenarios.
D, a sonic boom is only produced when a body is traveling faster than sound
Explanation:
Type II restriction enzymes are the familiar ones used for everyday molecular biology applications such as gene cloning and DNA fragmentation and analysis. These enzymes cleave DNA at fixed positions with respect to their recognition sequence, creating reproducible fragments and distinct gel electrophoresis patterns. Over 3,500 Type II enzymes have been discovered and characterized, recognizing some 350 different DNA sequences. Thousands more ‘putative’ Type II enzymes have been identified by analysis of sequenced bacterial and archaeal genomes, but remain uncharacterized.
