Answer:
B. It's larger than planet Mercury
Answer:
1. Map-based genome sequencing: a; c; f; g
2. Whole-genome shotgun sequencing: b
3. Both sequencing methods: d; e
Explanation:
Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.
Answer:
The correct answer is: upper esophageal sphincter.
Explanation:
The alimentary canal is a very long tract responsible for the digestion of the food. It is composed of several organs with many different and important functions. The alimentary canal also has a few sphincters, which are muscular valves that open and close when needed for the food to pass or be retained.
The first sphincter is the upper esophageal sphincter. One particularity of this sphincter is that is one of the few sphincters in the body that opens and closes under our conscious control, which happens when we decide to swallow our food.
From the first to the last, the order of the sphincters in the gastrointestinal tract is: upper esophageal sphincter, lower esophageal sphincter or gastroesophageal sphincter, pyloric sphincter, ileocecal sphincter, and anus.
Answer:
Most bacteria growth best within certain range of condition. By manipulating temperature and time, air, the proper amount of water acid and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Explanation:
Like all living things, bacteria need food, water and the proper environment to live and grow. The food product itself supplies the food and water needed for bacterial growth.he exact environmental requirements can vary from one type of bacteria to another. Most bacteria grow best within certain ranges of temperature, and have specific requirements related to their need for air, the proper amount of water, acid and salt. By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Bacterias need following optimum conditions to grow
1. Food (nutrients)
2. Water (moisture)
3. Proper temperature
4. Time
5. Air, no air, minimal air
6. Proper acidity (pH)
7. Salt levels
By altering anyone of them we can restrict or reduce the rate at which the bacteria grow.
A tumor is a mass of abnormally growing cells.
