Complete a punnet square.

If a Red Blood Cell is placed in a beaker in solution, the solution would have a higher concentration of solutes than the cell and this is an example of a hypertonic solution.

Osmosis simply refers to a process that typically involves the movement of a solvent molecule such as nail polish or water through a selectively or permeable membrane, especially from a region of higher concentration to a region of lower concentration.

In Science, a hypertonic solution can bed defined as a type of solution that contains a higher concentration of solutes such as water than the cell.

On the other hand, a hypotonic solution can bed defined as a type of solution that contains a lower concentration of solutes such as water than the cell.

DNA degrades over time. Dinosaurs went extinct about 66 million years ago, and so much time has passed that it is highly unlikely that any dinosaur DNA remains today. Dinosaur bones can survive millions of years, but dinosaur DNA almost certainly cannot.

The oldest DNA fragments found are only 800,000 years old, so cloning dinosaurs is probably impossible. True cloning also requires intact living cells and has been successful only in host animals of the same species. This also excludes mammoth clones. If you dig up a fossil today the dinosaur DNA in it would have fallen apart long ago.

So, as far as scientists know even with the best technology available today, it's impossible to make a dinosaur out of DNA. Scientists are now working to reverse extinction by bringing animals that disappeared from the earth long ago back into our lives. By manipulating the genetic code of a closely related species' DNA we can slowly build and manipulate a model of the species' DNA in reverse.

Only when there is space in the petri dish may cells reproduce (A, B, D). After one layer of cellular reproduction, cells stop.

Cell division, or mitosis (meiosis in germ cells), is a process that involves a number of dynamic processes and the coordinated interactions of numerous cellular parts. The DNA that has been copied condenses into chromosomes during mitosis and is then joined to what is known as the "mitotic spindle," a complicated structure.

The explanation is that new cells are created during mitosis whenever we suffer an injury. A parent cell divides into two daughter cells with an equal number of chromosomes during the mitotic phase.

An increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles are [tex]O_2[/tex].

During photosynthesis, green plants use their chlorophyll to absorb sunlight. This solar energy is then used to fix carbon dioxide and water into glucose while oxygen is liberated as a by-product of the reaction.

The process happens through a series of steps. Some happen in the presence of light while others happen without light. Those steps that require sunlight are said to be light-dependent while those that do not are said to be light-independent.

The overall equation of the reaction is written as follows:

[tex]6CO_2 + 6H_2O -- > C_6H_1_2O_6 + 6O_2[/tex]

Since the reaction depends on light, the brighter the light, the faster the rate of the reaction, all other factors being equal. The faster the rate of the reaction, the more bubbles of oxygen will be formed.

In other words, an increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles on the water plant are oxygen gas.

Through an osmotic process, water can freely go from a more diluted solution to a less diluted one. It follows its concentration gradient and does not need energy. Option 3 (or C) Water will move from B to A.

Osmosis is a simple passive transport process through which water molecules move from one side to the other of the membrane.

Water follows its concentration gradient, so it does not need energy  to be transported. Water moves from the most diluted side to the more concentrated one.

When dilutions have different concentrations, there is a difference in the number of water molecules moving from one side to the other.

Solutions reach a dinamic equilibrium when concentrations at each side of the membrane are the same.

In the exposed example, sections A and B are separated by a semi-permeable membrane, and A contains fewer water molecules than B.

Water moves from B to A because in section B there is a greater concentration of water than in A. So water follows its concentration gradient and moves forward to A.

Option 3 is correct.
