The correct answer is C.
The egg sinks in freshwater because it is more dense than the water. So, to make the egg float, you would have to increase the density of the water. Since salt water has a greater density than freshwater, you would add salt to the freshwater, thus causing the egg to float rather than sink.
Answer:
The movement of Xylem is unidirectional and phloem is bidirectional
Explanation:
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.
Answer:
Change the enzyme tolerance
Explanation:
Using enzymes in manufacturing is a very effective way to achieve many of the results that we desire. However, there are a number of conditions that must be taken into consideration when using this medium. Since enzymes require specific conditions to function; this is the limitation of using enzyme in manufacturing.
If you as the manufacturer finds that there are issues in the efficiency there are practical steps that can be takes with the current scientific advancements.
- Introduce a mutation: This should be one that changes the enzyme tertiary structure enough for it to tolerate a flux in conditions but does not interfere with production efficiency or cost of production.
- Slowly change conditions and allow evolution: This is in the case that the enzyme is produced on-site and the manipulation of the tertiary structure is a bit difficult. In organisms such as yeast or e. coli, this is practical and attainable albeit time consuming.
Finally, harnessing and manipulating the enzyme structure and function is an incredible advantage in manufacturing and options are available to optimize production.
Reversable. :) Hope I helped ya out.
