Imagine you have a garden with tomatoes.

In the laboratory assay on digestion of the protein BAPNA by trypsin, the purpose of including a tube with trypsin alone is to serve as a control for the experiment.

This control helps to identify any background activity or interference that may occur in the absence of BAPNA. By comparing the results from the tube with trypsin alone to those with both trypsin and BAPNA, you can accurately assess the specific activity of trypsin in protein digestion and eliminate any non-specific effects.

The process of messenger RNA being made from a template of DNA is known as transcription. During transcription, RNA polymerase enzyme binds to a specific region of DNA called the promoter and separates the two strands of the double helix.

During transcription, the RNA polymerase reads the DNA strand in the 3' to 5' direction, and synthesizes the RNA molecule in the 5' to 3' direction. The RNA polymerase adds nucleotides to the growing RNA chain in a sequence that is complementary to the template DNA strand. The RNA polymerase reads the DNA strand in a series of codons, each consisting of three nucleotides, and adds the corresponding nucleotide to the growing RNA chain. In eukaryotic cells, the newly synthesized RNA molecule, known as primary transcript or pre-mRNA, undergoes further processing before it can be used to direct the synthesis of proteins. This includes the removal of non-coding regions, called introns, and the splicing together of the remaining coding regions, called exons, to form the mature mRNA molecule. The mature mRNA molecule is then transported out of the nucleus and into the cytoplasm, where it can be used by the ribosomes to direct the synthesis of proteins.

e. condensation

Answer:

D.Predation

Explanation:

Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.

Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.

The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.

The pulse-chase technique is a commonly used experimental method in cell biology that allows researchers to track the movement and fate of molecules within cells.

The technique involves introducing a labeled molecule into a cell for a short period of time (the "pulse"), and then removing the labeled molecule and replacing it with an unlabeled molecule (the "chase"). By comparing the location and abundance of the labeled molecule with that of the unlabeled molecule at various time points, researchers can gain insights into the movement, localization, and turnover of the molecule within the cell.

The specific application of the pulse-chase technique can vary depending on the molecule of interest and the experimental question being addressed. For example, the technique has been used to study protein turnover, intracellular trafficking, and the dynamics of DNA replication and repair. Pulse-chase experiments are often conducted using radioactively labeled molecules, but non-radioactive labeling methods such as fluorescent tags can also be used.

If you are looking for biggest to smallest this is the answer. Or, who eats who.

Answer:

A

Explanation:

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Then fish get eaten by large predators, such as sharks, tuna, squid and octopus as well as marine mammals like seals and some whales form the top of the food chain. Next a shark is eaten by a whale. These whales have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions, and even large whales. Killer whales also hunt, attack, and eat sharks. That is a food chain from smallest to biggest :)

Answer: The reason for the increased number of drug-resistant bacteria being found in hospitals is due to MISUSE and OVERUSE of antibiotics.

Explanation:

Antibiotics is a type of drug that attacks bacteria microorganisms either by killing or eliminating the bacteria (that is, bactericidal) or by preventing further growth of the bacteria (that is, bacteriostatic). Antibiotics should be taken properly while being used to treat any diseases condition to prevent drug resistance by the bacteria from occurring.

The reason for the increased number of drug-resistant bacteria being found in hospitals is due to MISUSE and OVERUSE of antibiotics. This causes the bacteria to change the way they respond to these medicines making them become antibiotic resistance. When they infect an individual, the infections they cause are harder to treat than those caused by non-resistant bacteria.

The indicated cell is currently in the Metaphase phase. The correct option is D.

In metaphase, the nuclear envelope has already broken down, allowing the chromosomes to be exposed in the cytoplasm.

The chromosomes, which consist of two sister chromatids held together by a centromere, condense and become more visible.

They move towards the center of the cell and arrange themselves in a single plane, forming a line at the metaphase plate.

At this stage, the microtubules of the mitotic spindle called the kinetochore microtubules, attach to the kinetochores located on the centromeres of each chromosome.

The kinetochore microtubules exert tension on the chromosomes, aligning them at the metaphase plate with equal spacing between each chromosome.

Thus, the correct option is D.

The plasma membrane, also known as the cell membrane, is a thin layer of lipids and proteins that surrounds and encloses the contents of a cell. It plays an important role in maintaining the integrity of the cell and regulating the movement of substances in and out of the cell.

One key aspect of the plasma membrane is its ability to allow for diffusion, a process by which molecules move from an area of higher concentration to an area of lower concentration. This is driven by Brownian motion, the random movement of molecules due to collisions with other molecules.

Osmosis is a specific type of diffusion that occurs in liquid solutions. It is the diffusion of water molecules across a selectively permeable membrane, from an area of higher water concentration to an area of lower water concentration.

The solute is the dissolved substance in the solution, and the concentration of the solute can also affect osmosis. A higher concentration of solute will result in a lower concentration of water, and vice versa. The plasma membrane is selectively permeable, meaning it can control which molecules can pass through, which allows the cell to maintain the proper balance of water and solutes inside and outside the cell.

99%

Explanation:

at a salt solution concentration of 2%, plasmolysis first started to occur.  So the other 98% in the "solution" would have just been water. Since  water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.
