a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.

4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer.

Dafna1 [17]

Well I dont know exactly how you modeled your model in this activity (also, I notice this is a question from 2016), but I do know the two processes.

This is the process of making glucose in plants. Photosynthesis goes through two individual stages:
Stage 1: Light dependent reaction (depends on the presence of light; it can’t happen in the dark)
Stage 2: Light independent (dark reaction) (works in the absence of light, but calling it a dark reaction might be misleading; It can just as well happen in the presence of light).

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin

Andrei [34K]

Answer:

The correct answer would be 2 in 4.

According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.

Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.

Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.

The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.

The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.

Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.

Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.

The frequency of alleles in a population that is in hardy Weinberg equilibrium?

maksim [4K]

The answer would be D.

HWE states that genotype and allele frequencies in a population remain constant from generation to generation when evolutionary influences are absent(such as gene flow or natural selection).

Why do plant cells seem less affected by changes in solute concentration?

djyliett [7]

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.

The diffusion of water through a permeable membrane is called what

Sati [7]

Answer:

The diffusion of water is called osmosis.

Explanation:

Osmosis is a type of diffusion in which water molecules diffuse through a particular permeable membrane of high water concentration to areas of lower water concentration.
