which of the following statements describes areas of research for uses of bacteria in biotechnology?
bacteria are being studied in order to determine a way to eliminate all bacteria.
bacteria are being studied in order to find ways to increase antibiotic resistance.
bacteria are being studied to produce vaccines and biodegradable plastics.
bacteria are being studied to eliminate genetic engineering practices.
Which of the following is a goal of future bioengineering efforts?
farmers may one day be able to use selective breeding in agriculture.
scientists hope to reduce the ability of humans to be recognizable with technology scanning.
scientists hope to one day be able to reduce biodiversity in organisms.
artificial limbs could be created in order to replace those tissues when they are injured or stop functioning properly.
how can bacteria become resistant to antibiotics?
antibiotics are only effective for a short amount of time and have a limited shelf life, so bacteria can become resistant to them over time.
bacteria that have resistant genes pass them on to future generations that carry mutations that lessen the effectiveness of the antibiotics.
antibiotics have only been used in a limited way among animals and humans, allowing the limited exposure to bacteria to cause them to be resistant.
bacteria have very little variations in their genetic material from one generation to the next allowing them to withstand greater doses of antibiotics.

For the first question, the statement that describes areas of research for uses of bacteria in biotechnology is: "bacteria are being studied to produce vaccines and biodegradable plastics." This statement identifies two specific areas of research where bacteria are being used: the production of vaccines and the production of biodegradable plastics.
To answer this type of question, it is important to read each statement carefully and identify the one that accurately represents the areas of research for the use of bacteria in biotechnology.
For the second question, the goal of future bioengineering efforts is: "artificial limbs could be created in order to replace those tissues when they are injured or stop functioning properly." This statement describes one potential goal of future bioengineering efforts, focusing on the development of artificial limbs to replace damaged or non-functional tissue.
To determine the correct answer, it is important to evaluate each statement and identify the one that best represents a goal of future bioengineering efforts.
For the third question, bacteria can become resistant to antibiotics through a process called natural selection. The statement that accurately describes this process is: "bacteria that have resistant genes pass them on to future generations that carry mutations that lessen the effectiveness of the antibiotics." This statement describes how bacteria can acquire antibiotic resistance through the transfer of resistant genes and the accumulation of mutations that reduce the effectiveness of antibiotics.
To answer this question, it is important to understand the concept of antibiotic resistance and how bacteria can develop this resistance over time.
