Bacteria and bacteriophages are undergoing an evolutionary battle. In particular, phages that infect Salmonella enterica can use

outer membrane proteins, such as OmpF or TolC, for drug efflux or to attach to the bacterial surface. What would be the impact of a significant mutation of these phage proteins? Choose one: A. The efflux proteins would denature, and Salmonella would become susceptible to drugs and phage infection B. There would be no impact on the rate of phage infection for Salmonella. C. The efflux proteins would denature, but Salmonella would not become susceptible to drugs and phage infection. D. The phage may not be able to bind to Salmonella's s

Answer:

The correct answer to the question: What would be the impact of a significant mutation of these phage proteins? Would be, D: The phage may not be able to bind to Salmonella´s surface, blocking viral infection.

Explanation:

Bateriophages are viruses that are capable of infecting bacterial cells and using them as hosts, until they are destroyed. Just like in the human body, however, these phages depend on the presence of certain characteristics in the bacterial cell membrane to be able to infect its host and inject its genetic material. Science has found that bacteriophages use two ways of infecting a bacterial cell; a tail that is able to pierce certain portions of the membrane, but  certain conditions must be present on the bacteria for such a thing to be possible, and by using certain proteins on the bacterial wall, to connect to it. Due to evolution, bacteria are highly capable of adapting, and some, especially highly resistant strands, have been seen to form mechanisms to resist against phages. One such changes has been in the availability of membrane proteins, such as OmpF and ToIC, which are vital for phage infection of a bacterial cell. These changes in proteins have reduced the capacity of bacteriophages to infect bacteria, such as in this case, Salmonella enterica.

vesna_86 [32]
The cholecystokinin generates a satiety or nausea sensation to the brain, quenching the appetite once it has eaten enough, occurs naturally in the human organism in the small intestine, secreted from the cells of the duodenum and jejunum to promotes fats absorption in the digestion process.

List the products or outcomes for the following biological processes
Lubov Fominskaja [6]

Answer:

1- DNA replication: two identical DNA strands

2- Transcription: mRNA

3-Translation: proteins

4- Mitosis: two identical diploid somatic cells

5- Meiosis: four different haploid gamete cells

Explanation:

1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created

2- Transcription: the process by which DNA becomes mRNA

3-Translation: the process by which mRNA becomes proteins

4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells

5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells

3. What are some scientific explanations for the history of life on Earth?
KATRIN_1 [288]

Answer:

Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects

Human beings are responsible for the loss of forest. Why?​
Blababa [14]

Beause we cut down a lot of trees. Often, so many, that the health of a forest is irreparably damaged. A forest is not just a bunch of trees. It is a whole ecosystem, in which the trees anchor the growth of many other plant and animal species, hold the ground together to prevent erosion, and produce a lot of oxygen to support animal life. If you harvest too many of the trees, the local ecosystem stops being a forest and starts turning into something else
