The most common type of cancer in the oral cavity is squamous cell carcinoma and the most common area of the oral cavity that is affected by cancers are the lips and tongue. A systematic physical examination of the oral cavity must be done to differentiate a benign lesion to a potentially malignant ones.

Cells are categorized as either prokaryotic or eukaryotic. classify the characteristics below as being unique to prokaryotic cel
dezoksy [38]
Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size. 

Both cell types: use ribosomes to synthesize proteins, contain DNA. 

Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.

In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.

Explain how ligand A and ligand B can cause identical cellular responses in a cell?
Alexus [3.1K]

Answer:

Ligand A and ligand B can cause same cellular responses in a cell when they are attached to different receptors.

Explanation:

If two same ligands are attached to two different receptors, two different responses will occurs. Such type of response is present in acetylcholine, while when two different ligands attached to two different receptors, same response will occur. This type of response is present in glucagon and epinephrine etc. ligands are responsible for controlling the transcription process when it binds or attached to the DNA molecule of the cell.

A scientist decides to study the effect of salt on a particular type of bacteria. Arrange the steps of the scientific method in
Debora [2.8K]
The scientific method is a problem-solving approach used in Biology and other scientific disciplines. This method has five basic steps which help scientists test their hypotheses. The first step of the scientific method is to make an observation. In this particular example, the scientist observes probably that salt has chemical and physical properties which could affect the life cycle of bacteria. The second step would be to ask a question and that would be to ask whether salt indeed has any effect on that particular type of bacteria that he/she studies. The third step would be to form a hypothesis and that would be to state that the specific bacterial type will be strongly affected by the salt. The fourth step would be to predict that if the scientist exposed this bacterial type to a salty environment, the bacteria would not survive. The fifth and final step is to test this prediction and if the bacteria do not survive, then the scientist can conclude that salt affects this bacterial type.

Which means of particle transport is shown in Figure 7–4 above?
sattari [20]
The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require  the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
