Answer:

Bacteriophages are attaching to bacterial cell wall and injecting genetic material.

Explanation:

Bacteriophage:

A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.

Following are steps of bacteriophage infection:

  1. Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
  2. Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
  3. The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
  4. After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
  5. In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.

* The second step of the infection cycle is pictured here.

Ans: maintain homeostasis

Homeostasis is any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival. It is the stable state of an organism and of its internal environment. Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. The stable condition is the condition of optimal functioning for the organism, and is dependent on many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.

The ph of the water in several lakes in norway and sweden had decreased to below 5.0 due to an increase in acid rain. What is mo
arsen [322]

Answer:

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.
