In the process of filtration, the molecular weight cut-off (mwco) membrane plays a crucial role in separating different solutes based on their sizes.

In this case, the 200 mwco membrane was used to filter a mixture of solutes. The membrane allowed molecules with a molecular weight of 200 or less to pass through while retaining larger molecules. Therefore, the solute that did not appear in the filtrate using the 200 mwco membrane must have had a molecular weight higher than 200. It is important to note that the mwco of a membrane is not an exact measurement, and there can be variations in the size of molecules that pass through the membrane.

In conclusion, to determine which solute did not appear in the filtrate using the 200 mwco membrane, we need to know the molecular weight of each solute in the mixture. Based on the properties of the membrane, we can assume that the solute with a molecular weight higher than 200 did not pass through the membrane. However, it is important to consider other factors that may affect the filtration process.

Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.

The succession term refers to colonization and subsequent changes.

Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.

Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.

In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.

It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.

In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.

Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.

After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.

First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.

Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.

Grasses and pioneers keep modifying the ground and making it better with time.

Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.

Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.

This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.

In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.

Thrombin is an enzyme that catalyses the conversion of fibrinogen into fibrin. Fibrinogen is a soluble protein that is present in blood plasma. The reaction shown in Fig. 4.1 can be completed by naming the product of the reaction, which is fibrin.

When thrombin acts on fibrinogen, it cleaves off two small peptide molecules, called fibrinopeptides, from each fibrinogen molecule. This exposes specific sites on the fibrinogen molecule, which then bind to each other, forming long, insoluble chains of fibrin. These chains then cross-link with each other, forming a stable fibrin clot.

The conversion of fibrinogen to fibrin occurs during blood clotting. When there is damage to blood vessels, platelets in the blood come into contact with the damaged area and become activated. These activated platelets then release chemicals, including thrombin, which leads to the conversion of fibrinogen to fibrin. The fibrin clot that is formed helps to plug the damaged blood vessel and prevent further blood loss.

In summary, thrombin is an enzyme that catalyses the conversion of fibrinogen to fibrin, which occurs during blood clotting when there is damage to blood vessels. The product of the reaction is fibrin, which forms insoluble chains and a stable fibrin clot.

The two primary functions of lipids in humans are energy storage and serving as a structural component of cell membranes.

Lipids are a diverse group of organic compounds that perform a variety of functions in the human body. They play two main roles in the human body, Energy storage: Lipids are the primary means of energy storage in the human body, and they are stored in adipose tissue.

In comparison to carbohydrates, lipids have a high energy content, making them a more efficient means of storing energy. Adipose tissue also serves as insulation, helping to maintain body temperature.Structural Component of Cell Membranes: Lipids play a structural role in the human body as a component of cell membranes.

Phospholipids, for example, are a crucial component of the cell membrane, which serves as a barrier between the cell's interior and its environment. Cholesterol, a type of lipid, is also a significant component of cell membranes. It serves as a precursor to other steroid hormones, such as testosterone and estrogen, and is involved in the production of bile acids. It also plays a role in the absorption of fat-soluble vitamins.

Explanation:

Approximately 16% of the nucleotides in the sample will be thymine.



Chargaff's rule states that in DNA, the amount of adenine (A) is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). Therefore, if cytosine makes up 42% of the nucleotides, then guanine must also make up 42%.

To find the approximate percentage of thymine, we can use the fact that A=T and G=C. If we assume that the DNA sample contains only these four nucleotides, then the total amount of A+T must equal the total amount of G+C.

Since we know that G+C makes up 42%, then A+T must also make up 42%. Therefore, the combined percentage of A+T is 84%, and since A=T, each must be approximately 42%/2 = 21%.

Since we want to find the percentage of T alone, we can divide 21% by 2 to get approximately 16%.

After osmosis occurs in beaker A, the cell would be larger compared to its size at the start of the experiment.

Osmosis is the process in which solvent molecules move from an area of high concentration to an area of low concentration across a selectively permeable membrane. In this experiment, water moves into the cell, which has a higher solute concentration than the surrounding solution in beaker A. As a result, the cell swells and increases in size. If this process continues, the cell may burst due to the excess influx of water, leading to cell death. Therefore, it is important to maintain the balance of solutes and water inside and outside the cell.
