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>
Medal i believe because i looked it up
Answer:
The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.
Explanation:
In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.
Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.
In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).
Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

Allele that causes yellow eyes (Y) is
dominant over the allele that causes orange eyes (y)
Y = 85% = 0.85 and
y = 100% - 85% = 15% = 0.15
f(y) = square root of y = √y = √0.15 =
0.387
frequency of the allele that causes
orange eyes = 0.387
Once we know the value of y, Y + y = 1
Putting the value of y, we get
Y = 1 – 0.387
<span>Frequency of the dominant allele that
causes yellow eyes = 0.61</span>
Answer: Beginning from the inside and moving towards outside the sun has six layers. Sun is the ultimate source of energy for all the living organisms on earth. The heat and light that comes out of the sun is through the various layers that is present in the sun.
1. Innermost core: It is the region from where the sun gets all the energy. Here hydrogen and helium is present. Due to high pressure of the surrounding layers hydrogen fuses into helium releasing high energy photons.
2. Radiative zone: The high energy photons are now transferred from core to radiative zone. Here the high energy photons are constantly absorbed and re-emitted. It takes millions and billions of years for these high energy particles to come out of this radiative zone.
3. Convective zone: The temperature of this region is quite cooler as compared to that of core and radiative zone. The plasma present in this region makes the magnetic field of the sun.
4. Photosphere: It is the region where sunspots are found. These are called by the magnetic field of sun.
5. Chromosphere: This region is red in color. It contains filaments of gas that rise up from the surface of the sun. This region is cooler than photosphere.
6. Corona: It is the outermost layer of sun and the temperature is much higher here. Many kinds of gaseous emissions takes place make the sun bright and hot.
