B. Because virus need the hosts dna to multiply
Answer:
Microbial mats.
Explanation:
Microbes formed sheets that were able to capture layers of sediment is called microbial mats. These mats of microbes provide good fossil evidence to the researchers. These microbial mats consist of bacteria and archaea which is considered the earliest form of life on earth. These microbial mats grow on moist places as compared to dry environment. About 3,500 million years ago, these microbes are the most important members of earth and maintainers of the ecosystems.
Answer:
output contract
Explanation:
An output contract is an example of a contract where an agreement is reached between the seller and the buyer that, all the production seller will be bought by the buyer. This means that, an agreement is reached that all the item that the seller is capable of producing will be entirely bought by the buyer.
In this case, the entire premium red wines produced by the Vino Tinto Inc. will be bought by the winery in Spain.
Thick or dense smears less likely to provide a good smear preparation for microscopic because it will diminish the amount of light that can pass through making it difficult to visualize the morphology of single cells under the microscope. Some times the stain can't penetrate all of the bacteria.
<h3 /><h3>What is a microscopic smear?</h3>
- A smear is a microscopic specimen.
- A swab or loop, or the edge of another slide, is used to spread the sample to be examined, such as blood or microbial culture, thinly and unevenly across the slide.
- Smear preparation involves spreading a small amount of sample on a slide and air drying the film before staining and microscopy.
- The conventional method, blood film method, drop and rest method, and water-wash method are the four types of smearing methods.
- Smear microscopy entails collecting a biological sample (typically sputum or other clinical material), fixing it thinly on a glass slide, and staining it with a dye that binds specifically to mycobacteria (making them easier to identify under a microscope).
