"The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 billion years ago. These fossils are of structures known as stromatolites, which are, in many cases, formed by the growth of layer upon layer of single-celled microbes, such as cyanobacteria. (Stromatolites are also made by present-day microbes, not just prehistoric ones.)
The earliest fossils of microbes themselves, rather than just their by-products, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago
Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago. However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible)."

Answer:
To increase white blood cells
Explanation:
- Neutrophils are a type of white blood cells and when there is a reduction in their number in the body then such a condition is termed as neutropenia.
- Filgrastim is a bone marrow stimulant that is a recombinant form of DNA and acts as the granulocyte-colony stimulating factor and hence, stimulates the bone marrow to produce neutrophils.
- Therefore, when the client is diagnosed with neutropenia that is low neutrophil count it is necessary to increase the neutrophil count and for this purpose filgrastim is prescribed.
Im gonna have to say that the answer is B for this one.
The action of phagocytes considered a nonspecific response because it is a response to any type of harmful substance with out any specificity.
Phagocytosis is a process in which a cell engulf any molecule using its plasma membrane. Phagocytes provide non specific defense mechanism as it the first line of defense of our body. our immune system has to tackle several types of foreign particles, Viruses, Bacteria and harmful proteins. This non specificity of action makes the response quicker than the specific
