Answer:
Plant cell seems less affected by the changes in solute concentration due to presence of cell wall.
Explanation:
The principle difference between plant cell and animal cell is that plant cell contain cell wall but animal cell does not.
The presence of cell wall prevent the osmotic lysis of the cell when the cell is kept in a hypotonic solution.
In case of plants the solute concentration of cytosol is greater than that of extracellular matrix.The entry of water inside the plant cell increases the turgor pressure that pushes both cytosol and plasma membrane against the rigid cell wall.
Answer:
Both C and E are reasonable answers.
Explanation:
Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.
A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.
B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.
C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.
D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.
E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.
Answer:
Yes, it accelerates
Explanation:
We have that:
The ball was stationary implies that its initial velocity, u = 0
It gained 5m/s means that its final velocity, v = 5m/s
Using first law of newton, we can determine whether it accelerates or not.
Substitute values for v and u
Make a the subject
<em>This implies that the ball accelerates over a period of time t</em>
<em></em>
Another way to tell if it accelerates or not is to consider the change in velocity.
When there is an increment in velocity of an object, the object accelerates.
In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
This suggests that the protein is targeted to Golgi apparatus.
Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.
Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.
