The right answer is going to move the blood cells and the cells will shrink.
Osmotic plasmolysis is a contraction of the cytoplasm of a cell by vacuolar water exit. This occurs during the exerting of osmotic pressure to the outside, exosmosis when the cell is immersed in a hypertonic solution. Plasmolysis leads, of course, to cell death.
Plasmolysis is thus the process by which cells lose water in a hypertonic solution.
The dehydration can cause the loss of water from the blood plasma. As the loss of water occurs, the osmolarity of the plasma is increased. Due to the increase in the osmolarity of the plasma, the blood cell would become hypotonic with respect to plasma.
This would result in loss of water molecules from the blood cells. So, the red blood cell would lose water molecules and will shrink.

b. tests experimental and control groups in parallel.
c. is repeated many times to make sure the results are accurate.
d. keeps all variables constant.
The correct answer is B. Tests experimental and control groups in parallel
Explanation:
In science, a controlled experiment is a type of experiment in which scientist intervene or manipulate variables. This often implies scientists use a control group in which the variable is constant and an experimental group that has a different treatment or changes in the variable studied. This allows scientists to evaluate the effect of the variable by comparing the results of both groups and thus confirm or discard a hypothesis. Therefore, a controlled experiment can be defined as on that "tests experimental and control groups in parallel".
A controlled experiment is one that tests experimental and control groups in parallel, with all other variables kept constant. This enables the scientist to observe the impact of a single variable.
A controlled experiment is one that can be defined as an experimental set up in which the scientist keeps all variables constant, except for the one being studied. The correct option here would be option 'b'. Such an experiment tests experimental and control groups in parallel.
This methodology allows the researcher to observe the effect of one variable on the study subject while ensuring that all other conditions remain the same. For example, if you were to experiment with plant growth, you might keep factors like sunlight, water, and type of soil constant while changing the type of fertilizer used.

B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
Solids have the least amount of energy among the four physical states of matter because their particles are held tightly together and can only vibrate, possessing less thermal energy than in the liquid, gas, or plasma states.(Option D)
The correct statement about the energy level of solids is that solids have the least amount of energy among the four physical states of matter. In a solid, the atoms or molecules are held close together by strong intermolecular forces, which significantly restricts their ability to move. As a result, the particles can only vibrate about fixed positions, and this vibrational motion accounts for the thermal energy in solids.
This is less energy than the particles have in liquid, where they can move freely but are still close together, and much less than in gas, where the particles have enough energy to break away from one another and fill the available space. In plasma, which is an ionized state with even higher energy, particles have the most energy compared to the other states of matter.

b. polymerase chain reaction
c. homologous recombination
d. Non-homologous end joining
Answer:
Option (a) and (d).
Explanation:
The breaks in DNA molecule may occur due to replication error and oxidizing agent. The double-stranded breaks in DNA can be corrected by Homologous end joining and non homologous end joining.
Homologous end joining is used to repair the DNA present in G2 nad S phases of the cell cycle. The homologous sequences of DNA is used to repair the DNA. Non homologous end joining occurs in the cell present at G0 and G1 phase of the cell cycle. The DNA broken ends are juxtaposed and later rejoin together by DNA ligase.
Thus, the correct answer is option (a) and (d).
