During osmosis, the semi-permeable membrane is one that:
A. does not allow any particles to pass through.
B. allows only very small particles or water through.
C. allows only very large particles through.
D. decides what particles to let through based on cell signals.

Answers

Answer 1

During osmosis, the semi-permeable membrane is one that: (B) allows only very small particles or water through.

Osmosis is the process of movement of solvent molecules from their area of high concentration to the area of low concentration through a semi-permeable membrane. This process does not require any energy for the movement of solvent. This phenomenon is applied during the dialysis of blood.

Semi-permeable membrane (SPM) is a fine partition either natural or synthetic that allows the movement of solvent molecules only through it. The example of natural SPM is cellulose, egg membrane, etc. and of synthetic SPM is cellophane.

Answer for 5:

The answer for 5 would be  C. Nitrogen oxides and sulfur oxides.

Explanation:

Acid rain becomes the result when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents.

Answer for 6:

Precipitation that is more acidic than normal because of air pollution; caused by the emissions from power plant and factories that burn coal and oil. So then basically, precipitation collects the acidic particles and gases and becomes acidic.

Some effects:

Acid rain can land on statues, buildings, and other manmade structures, and damage their surfaces. Acid rain leaches aluminum from the soil. In result, the aluminum then may be harmful to plants and animals both. Acid rain removes minerals and nutrients from the soil that trees need to grow and this thereby lowers their fertility.

Do you think risk assessment would be a better strategy for a prey animal than frequent vigilance? explain your reasoning.

Answers

Yes, the risk assessment would be a better strategy for a prey animal than frequent vigilance.

The prey would be aware of their surroundings and search for signs of risk, such as the presence of a predator when doing a risk assessment. When they see a risk, they become more alert so they can react to the threat.

On the other hand, persistent vigilance is when a prey animal is constantly on guard and ready for danger. Although risk assessment may increase an animal's likelihood of being eaten by a predator, it also saves a significant amount of energy by only making the prey aware of the danger when it is actually present.

Overall, prey animals who employ risk assessment will profit in comparison to those that use continual vigilance since the energy they save can be used for other activities like finding food or escaping a predator.

Under a microscope, some cells can appear to be between metaphase and anaphase (Figure 7). Explain this observation.

Answers

Dividing cells can appear in between 2 stages of division because cell division is a continuous spectrum.
Cell division
The different stages of cell division include:
•prophase
•metaphase
•anaphase
•telophase
The transition from one stage of division to another is not discrete. Rather, it is a continuous process, and cells in transition phases between two stages are most observed under the microscope.

The observation of cells appearing to be between metaphase and anaphase under a microscope suggests a potential delay or disruption in the normal progression of cell division.

What is cell division?

Cell division, also known as cell replication or cell reproduction, is the process by which a parent cell divides into two or more daughter cells. It is a vital process for growth, development, and tissue repair in organisms. The two main types of cell division are mitosis and meiosis.

In mitosis, a parent cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. The process involves several distinct phases, including prophase, metaphase, anaphase, and telophase. During metaphase, the chromosomes align at the equator of the cell.

Anaphase is the stage when the sister chromatids, which are the replicated chromosomes, separate and move towards opposite poles of the cell. This ensures that each daughter cell receives an equal set of chromosomes during cell division.

Observing cells that appear to be between metaphase and anaphase suggests a potential disruption or delay in the normal progression of cell division, possibly due to regulatory or structural abnormalities in the cell or its environment.

No, as the S phase develops, the amount of DNA in each cell varies, giving the S phase cells a range of fluorescence levels.

The S phase is what What transpires in this phase?

Stage S. During the S phase, DNA replication happens. After duplication, each chromosome splits into two sister chromatids (the products of DNA replication). Prior to mitosis, when the sister chromatids separate into two daughter cells, they are still connected.

A cell spends the majority of its time in the interphase phase, which is when it matures, replicates its chromosomes, and prepares to divide. The cell enters mitosis after exiting interphase to complete its division.

Many proteins are used in protein synthesis to help generate the chemical reactions. What is the relationship between enzymes and activation energy?.

Answers

When an enzyme catalyzes a reaction it decreases the activation energy of the reaction.

Enzymes are biocatalysts. A catalyst lowers the activation energy of a reaction. The lower the activation energy of a reaction, the faster it will go. Therefore, enzymes speed up reactions by lowering their activation energy. Enzymes bind substrates at key points in their structures called active sites. They are usually very specific, binding only specific substrates for specific reactions.

Without enzymes, most metabolic reactions would take much longer and not be fast enough to sustain life. Enzymes are proteins and biochemical reactions occur by lowering the activation energy of a reaction It increases the possibilities and makes those reactions thousands or millions of times faster than without the catalyst.
