Out of the following given choices;
A. The cell is unable to get more water into the cell.
B. The cell is unable to build more protein molecules.
C. The cell is unable to produce water molecules inside the cell.
D. The cell is unable to maintain a stable internal environment.
<span>The answer is D. Due to high amounts of proteins in the cell, osmotically
active proteins cause the internal environment of the cell to be hypertonic to
the extracellular fluid. This causes excess water to enter the cell by osmosis and
resulting in lysis. </span>
Answer:
The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.
Explanation:
Data:
Horizontal axis = time.
Vertical axis = velocity (m/s).
A line runs in straight segments
- <em>from 0 seconds 15 m/s.</em>
- <em>to 1 seconds 13 m/s.</em>
- <em>to 2 seconds 10 m/s.</em>
- <em>to 3 seconds 4 m/s.</em>
- <em>to 4 seconds 0 m/s.</em>
- <em>to 6 seconds 4 m/s.</em>
According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.
<em>In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.</em>
When taken out of the freezer and placed on a piece of foil, 2 pieces of ice will melt at the same rate because the piece of foil is at room temperature and so are the pieces of ice.
That's the best way that I can explain it :)
I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the
first tile from the left.
Then, the
first tile from the right is where the Leu is formed.
On the
second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them:
third tile from the right,
third tile from the left,
second tile from the left.
Answer:
The membrane will move to the left in view of the applied pressure.
Explanation:
The scenario described can be perfectly illustrated through understanding the concept of osmosis.
Osmosis can be defined as the movement of particules or molecules in a solvent from a region of lower concentration to a region of higher concentration, through a semi permeable membrane.
To put differently, the movement of water molecules is from a region of lower osmotic pressure to a higher one. And for osmosis to be achieved and water molecules evenly distributed, pressure built must be slow and steady to a state of high or equilibrium.
This often results to movement of membrane to the left as a response to the osmosis phenomenon. Increasing the number of water molecules in the extra cellular fluid will thus accelerate this process, increase the pressure built up, and thus generate ripples from a lower area to a higher one. Osmosis is thus gradual and steady.
