Which of these microbes causes "walking pneumonia"?

Karolina [17]

Answer:

Walking pneumonia can be caused by the microbes mycoplasma pneumoniae and chlamydophila pneumoniae.

Explanation:

Atypical pneumonia, commonly known as walking pneumonia, is a type of pneumonia which is not caused by a single pathogen or a single type of pathogen. The organisms that cause walking pneumonia are called atypical organisms. Therefore, disease can be caused by special bacteria, fungi, viruses and protozoa.

Examples of atypical organisms include: chlamydophila pneumoniae, chlamydophila psittaci, francisella tularensis, mycoplasma pneumoniae, etc.

Therefore, Walking pneumonia can be caused by the microbes mycoplasma pneumoniae and chlamydophila pneumoniae.

In 3-5 sentences write a description of how the 4 terms, DNA, chromosomes, genes and traits, are related and/or work together to

wel

Answer:

Please find the explanation below

Explanation:

Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.

The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.

Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
