What do U need help with

DNA is coded to RNA, which must travel from the nucleus to the cytoplasm to be read. Why does the cell need to transcribe the DNA into RNA rather than copying the DNA directly? (1 point)DNA requires too much energy to code; building RNA is more efficient.

DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.

DNA cannot be copied; it must be translated to RNA and then back to DNA.

DNA cannot be read by ribosomes; they can only read RNA.

Answers

Answer:

DNA is double-stranded and cannot fit through the nuclear membrane; RNA is single-stranded.

Explanation:

Match each cell type with its description.___natural killer cell
A. stains with basic dye methylene blue, has large amounts of histamine in granules, and facilitates allergic responses and inflammation


___basophil
B. stains with acidic dye eosin, has histamine and major basic protein in granules, and facilitates responses to protozoa and helminths


___macrophage
C. recognizes abnormal cells, binds to them, and releases perforin and granzyme molecules, which induce apoptosis


___eosinophil
D. large agranular phagocyte that resides in tissues such as the brain and lungs

Answers

Answer:

1. A natural killer cell identifies unusual cells, combines with them, and discharges perforin and molecules of granzyme that stimulates apoptosis.  

2. A basophil comprises huge concentrations of histamine in granules, gets stain with basic dye methylene blue, and helps in inflammation and allergic reactions.  

3. A macrophage refers to a huge agranular phagocyte, which is found within the tissues like lungs and brain.  

4. An eosinophil comprises histamine and major basic protein in granules gets stain with acidic dye eosin and helps in reactions against the helminths and protozoa.  

Final answer:

The natural killer cell recognizes and destroys abnormal cells, the basophil facilitates allergic responses and inflammation, the macrophage is a large cell that resides in tissues, and the eosinophil facilitates responses to certain parasites.

Explanation:

Here is the correct match for each cell type with its description:

  1. Natural killer cell: C. recognizes abnormal cells, binds to them, and releases perforin and granzyme molecules, which induce apoptosis
  2. Basophil: A. stains with basic dye methylene blue, has large amounts of histamine in granules, and facilitates allergic responses and inflammation
  3. Macrophage: D. large agranular phagocyte that resides in tissues such as the brain and lungs
  4. Eosinophil: B. stains with acidic dye eosin, has histamine and major basic protein in granules, and facilitates responses to protozoa and helminths
