Answer:

Independent Variable = The thing you change

Dependent Variable = The thing you measure

Explanation:

An independent variable is the thing that you are changing in your experiment to be able to get different results. For example, if a question says "What will happen to a cup of tea when you change the temperature of the water added to it?"... then the independent variable will be the temperature of the water.

A dependent variable is the thing that you are measuring. For example, if you are studying the amount of light absorbed from different surfaces, then the dependent variable is the unit of light absorbed, which would be measured in Au (Absorbance unit).

You can now take this knowledge and apply it to your question.

Because the structure of a prokaryotic ribosome is not the same as that of a ribosome in an animal cell some antibiotics can block protein synthesis in bacteria without harming the eukaryotic host.

Explanation:

Antibiotics are medicines used to cure infectious diseases by killing bacteria or preventing their replication. One of the mechanisms of action of antibiotics is to act on ribosomes and inhibit protein synthesis.

The ribosomes of prokaryotic cells are 70S, with a ribosomal RNA (rRNA) content of 66-68%, while the ribosome of the animal cell has a sedimentation coefficient of 80S, with an rRNA percentage of 60%. This difference makes it possible for some antibiotics, such as aminoglycosides, to affect bacterial protein synthesis but not the animal cell's protein synthesis.

    The other options are not related to the difference in ribosomes between prokaryotic cells and animal cells.

The hypothesis that is supported by the data is that the milkweed population is a biotic factor whose population decreases as the amount of sunlight, an abiotic factor, decreases. Option A.

The biotic factors of the environment are all the living organisms in the environment. The abiotic factors, on the other hand, are the nonliving components of the environment, such as sunlight, precipitation, pH, etc.

Thus, in the data shown, the milkweed is a biotic factor while the sunlight is an abiotic factor.

The data further shows that as the amount of shade increases, the population of milkweed also decreases. The amount of shade available in a place is a function of sunlight. The more sunlight, the lesser the amount of shade available, and vice versa.

In order words, the population of the milkweed plant decreased in response to the decrease in the amount of sunlight (which increases shade) available in the environment.

Answer:

NaHCO3 is an inorganic compound.

Explanation:

Based on the generally accepted definition of organic and inorganic compounds, I would classify NaHCO3 as an inorganic compound. This is because organic compounds are defined as compounds that contain carbon atoms, whereas inorganic compounds are compounds that do not contain carbon atoms.

In the case of NaHCO3, while it does contain carbon atoms, it is not typically considered an organic compound due to its inorganic properties and behavior. It is an ionic compound that does not exhibit the characteristic properties of organic compounds such as covalent bonding, low melting point, and low boiling point. Additionally, it is commonly found and studied within inorganic chemistry, rather than organic chemistry.

The characteristic of renal cell carcinoma (RCC) is a predisposition to infiltrate the inferior vena cava (IVC) through the renal vein. According to estimates, such tumor thrombus extension occurs in 4–10% of instances.

The majority of treatment is still surgical excision because it has not been demonstrated that the existence of tumor thrombus affects survival. The lining of the proximal convoluted tubule, a portion of the tiny tubes in the kidney that carry primary urine, is where renal cell carcinoma (RCC), a kind of kidney cancer, develops. Renal cell carcinoma is the term for this.

The veins that drain the kidney are called renal veins. They join the vena cava inferior with the kidney. Some individuals instead have the left renal vein travel behind the abdominal aorta.

Yeah your answer is correct

The spindle-attachment checkpoint is responsible for ensuring proper attachment of chromosomes to the spindle fibers during cell division. If this checkpoint is inhibited by a drug, it can lead to errors in chromosome segregation and cell division. Based on the given information, if the drug inhibits the activity of the spindle-attachment checkpoint, the cell would most likely be blocked at the metaphase stage of the cell cycle. During metaphase, the chromosomes are aligned at the center of the cell and attached to the spindle fibers. The spindle-attachment checkpoint monitors the attachment of chromosomes to the spindle fibers during this stage. If this checkpoint is not functioning properly due to the drug, the cell will not progress to the next stage of cell division, which is anaphase.

The cell is the smallest unit that composes the bodies of living things and is the place where the functions of life are carried out. Cells were first discovered by an English scientist named Robert Hooke in 1665. Functionally, cells function to carry out life functions (organize life if the constituent cells function), then form organisms. Cell structure is an arrangement and relationship between elements or cell elements that are interconnected in a unified cell system as the smallest unit of living things.

a. Lysosomal enzymes are synthesized in the endoplasmic reticulum and then modified in the Golgi apparatus before being transported to lysosomes.

b. The cis-Golgi and Trans Golgi Network (TGN) are important in the tagging and sorting of lysosomal proteins. Proteins are tagged with a Mannose-6-Phosphate (M6P) marker in the cis-Golgi and then sorted in the TGN for transport to lysosomes.

c. Lysosomal storage diseases are caused by a lack of one or more lysosomal enzymes required for proper lysosome function. Replacement enzyme therapy biologics involve administering the missing enzyme to patients. The Mannose-6-Phosphate receptor on the surface of cells recognizes and binds to the M6P marker on lysosomal enzymes, facilitating their uptake into cells. Lysosomal enzymes are found at low levels in normal cells in the extracellular medium because they are constantly being recycled and reused within cells to maintain proper lysosome function.

Answer:

Alfred Hershey and Martha Chase

Explanation:

In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.
