Answer:
The product that must be produced to kill a bacterium —which causes a disease— is an antibiotic, which through biotechnology can investigate the structure of the bacterium and synthesize the chemical formula needed to produce antibiotics in high amounts.
Explanation:
Antibiotics are specific medicines for the treatment of infectious diseases, produced by bacteria. <u>Antibiotics can kill bacteria and prevent their replication</u>.
If a disease is produced by bacteria, the product that is necessary to kill those microbes is an antibiotic, for which biotechnology is useful.
By using biotechnology —a branch of biology that uses technology as a research and development tool— it is possible:
- <em>Know the structure, functions and behavior of pathogenic bacterial strains.
</em>
- <em>Create chemical formulas -antibiotics- that serve to effectively eliminate bacteria, and cure infectious diseases.
</em>
- <em>The synthesis and production of antibiotics on a large scale, allowing their sufficient availability for use.</em>
Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :
Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, 
But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, 
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
The correct answer is D. Accessory fruit
Explanation.
Fruits are structures that develop from the fertilized ovary of plants and that contain the seed of it, this includes simple, aggregate and multiple fruits. However, there is one type of fruits that do not develop from ovary but from other tissues that are usually near the ovary, these fruits are called accessory or pseudo fruits as they do not fit completely the definition of regular fruits, this includes fruits such as strawberries or pineapples that develop from tissues different to the ovary.
