Which lipids will you find associated with the Cell membranes and the organelles of Cells?

User Avatar

Asked by Wiki User

Phospholipids are the most abundant lipid found in cell membranes, forming a lipid bilayer. Cholesterol is also present in cell membranes, helping to maintain membrane fluidity. Additionally, certain organelles like the endoplasmic reticulum and Golgi apparatus contain lipids such as phospholipids and cholesterol in their membranes.

What is the cost of compound microscope?

User Avatar

Asked by Wiki User

The cost of a compound microscope can vary widely depending on the brand, features, and quality. Basic models typically start around $100-$200, while more advanced models with additional features can range from $300-$1000 or more. Customizable options may also affect the final price.

What electrical charge dye would work better on a bacteria to stain it?

User Avatar

Asked by JuanCarlosDelgado

A cationic dye, which has a positive charge, would work better on bacteria to stain it. This is because bacterial cell walls are negatively charged, so the positively charged dye will be attracted to and bind with the cell wall more effectively.

What condenser value do you want when using 100X objective lens?

User Avatar

Asked by Wiki User

When using a 100X objective lens, you typically want to use a high numerical aperture (NA) condenser lens to match the high NA of the objective lens. A condenser with a NA value equal to or greater than the NA of the objective lens (typically around 1.4) is recommended for optimal resolution and contrast in microscopy.

What happens if gram positive cell are not decolorized?

User Avatar

Asked by Wiki User

If gram positive cells are not properly decolorized during the Gram staining process, they may retain the primary stain (crystal violet) and appear falsely as gram negative cells. This can result in misclassification of the bacteria, leading to inaccurate identification and potential treatment errors.

What is the small glass square that goes on the wet mount slide?

User Avatar

Asked by Wiki User

The small glass square is called a coverslip. It is used to place over the specimen and mounting medium on a wet mount slide to prevent evaporation, protect the specimen, and provide a flat viewing surface for microscopy.

RNA bases are: adenine and uracil & guanine and cytosine.

DNA bases are: adenine and thymine & guanine and cytosine.

The main difference is the uracil and thymine. Hope this helps...

Does the suppository cause staining?

User Avatar

Asked by Wiki User

Suppositories can potentially cause staining due to the medication's ingredients. It's advisable to use a sanitary pad or underwear liner to prevent staining on clothing. If you have concerns about staining, consult with a healthcare provider for guidance.

Is Agar a homopolysaccaride or heteropolysaccaride?

User Avatar

Asked by Wiki User

Agar is a heteropolysaccharide composed of agarose and agaropectin. Agarose makes up the majority of agar and consists of repeating units of agarobiose, while agaropectin is a minor component with a more complex structure.

Where are most blood cells produced in a human body?

User Avatar

Asked by Wiki User

Most blood cells, including red blood cells, white blood cells, and platelets, are produced in the bone marrow of a human body. The bone marrow is found in the cavities of bones such as the pelvis, sternum, and long bones.

What functional class of membrane proteins do the immune system detect?

User Avatar

Asked by Wiki User

The immune system detects antigens which can be proteins, lipids, or carbohydrates displayed on the surface of cells. In terms of membrane proteins, the immune system detects antigens presented by major histocompatibility complex (MHC) proteins on the surface of cells to distinguish between self and non-self molecules.

Why bacteria go to bottom of the broth culture?

User Avatar

Asked by Wiki User

Bacteria can sink to the bottom of a broth culture due to their weight and increased cell density as they multiply. Factors like gravity, viscosity of the broth, and bacterial cell characteristics can contribute to the settling process. This phenomenon can be observed in stationary phase cultures or when nutrient depletion causes the bacteria to clump together and settle.

Which component of cell membranes are embedded within the membrane and are exposed to both the inside and the outside of the cell?

User Avatar

Asked by Wiki User

Integral membrane proteins are components of cell membranes that are embedded within the membrane and span across it, exposing portions of the protein on both the inside and the outside of the cell. These proteins play crucial roles in various cellular functions, such as cell signaling and transport.

Did you stain the bacterial cell wall or the cell cytoplasm?

User Avatar

Asked by Wiki User

Yes, it is. Using the Gram staining method, the wall can be seen.

What is the differentce between a smooth endoplasmic reticulum and a rough endoplasmic reticulum?

User Avatar

Asked by Wiki User

The rough endoplasmic reticulum (RER) has ribosomes attached to its surface, which gives it a rough appearance under a microscope and is involved in protein synthesis and processing. The smooth endoplasmic reticulum (SER) lacks ribosomes, appears smooth, and is involved in lipid metabolism and detoxification of drugs and toxins.

Asked by Wiki User

The price of one capsule of Fatrol may vary depending on the retailer, location, and any ongoing promotions. It is recommended to check with the specific store or online platform where you plan to purchase Fatrol for the current pricing information.

What does testing the lymphoproliferative response of mononuclear cells to polyclonal stimulators mean?

User Avatar

Asked by Wiki User

Testing the lymphoproliferative response of mononuclear cells involves measuring the ability of these immune cells to proliferate in response to nonspecific stimulators like mitogens or antigens. This test is used to evaluate the overall functionality of the immune system and can help assess immune cell function in various conditions, including immunodeficiency disorders and autoimmune diseases. The results can provide insights into the immune system's ability to mount an effective immune response.

What group of microbes are smallest in size?

User Avatar

Asked by Wiki User

The smallest group of microbes are viruses, which are not considered living organisms because they cannot replicate on their own and rely on host cells to multiply. They are much smaller than bacteria, archaea, and fungi.

When viewing object under power you are able to see a larger field of view but not as much retail?

User Avatar

Asked by Wiki User

When viewing an object under higher magnification, you can see a larger field of view and take in more surrounding details. However, the resolution or sharpness of the image may decrease slightly compared to viewing at lower magnification, which can affect the ability to see fine details or textures up close.

Why centrioles are present in animals but not in plants?

User Avatar

Asked by Wiki User

Centrioles are present in animals because they are needed for cell division, particularly in forming the spindle fibers that separate chromosomes during mitosis. Plants, on the other hand, have different structures called microtubule organizing centers that fulfill a similar function, so they do not require centrioles.

What is weed management?

User Avatar

Asked by Wiki User

Weed management involves strategies and techniques used to control or eliminate unwanted or invasive plants (weeds) in agricultural fields, gardens, lawns, and natural areas. This can include using mechanical, cultural, biological, and chemical methods to prevent or reduce weed growth and competition with desired plants. Effective weed management is essential for maintaining the health and productivity of plant systems.

What is the constant variable in investigation of fungi growth mold?

User Avatar

Asked by Wiki User

The constant variable in investigating fungi growth mold could be the temperature, humidity level, or type of substrate being used for growth. This variable remains unchanged throughout the experiment to ensure that any observed differences in growth can be attributed to the independent variable being tested.

What pathogen can grow from improperly heated foods?

User Avatar

Asked by Wiki User

Clostridium botulinum is a pathogen that can grow in improperly heated foods.
