Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solu
Readme [11.4K]

Answer:

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Which of the following scenarios would be most likely to cause a weak point in the aorta to rupture, and why? (2 points)
REY [17]
<span>I believe the answer is,

High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward.

This indicates high blood pressure that causes rupture of the aorta or aorta dissection.</span>

Which of the following best describes the mechanism by which steroid hormones control gene expression? View Available Hint(s) Wh
Veseljchak [2.6K]

Answer:

Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.

Explanation:

Mechanism of action of steroid hormones is as follows:

  • Steroid hormone enters cell and bind to the receptor.
  • Translocation of activated receptor- ligand complex into nucleus.
  • This complex then bind to another receptor on the chromatin.
  • Steroid receptors form dimers.
  • Act on DNA
  • These hormone-receptor complexes then bind HREs and influence gene expression.
  • Augmentation or Suppression of transcription.

Rufina [12.5K]
The commence is off base with regards to the enthusiasm for creating fake blood. The intrigue is on the grounds that the timeframe of realistic usability of put away blood is extremely constrained. The other intrigue is concerning transfusion responses related with red platelet antigens that can bring about lethal responses and cause delays in finding good blood that hazard understanding lives. At present the rate of securing HIV disease through blood transfusions has been computed to associate with one case for every a million or two million transfusions. That viewpoint has been tackled with respect to testing however alternate issues still remain and they persuade the proceeded with look for simulated blood. Other developing infections like Zika and other obscure infections additionally makes a requirement for such research.
