Answer:

- Some native plant population will decline

Explanation:

If the boat brings in a nonnative plant into the lake, than that means that lake will get an invasive species. The plant that will be brought will be an invasive species as it is not native to that lake. The invasive species usually manage to out-compete the native species, often resulting in rapid increase in the numbers of the invasive species, and rapid decline, or even extinction of some of the native species as they are not able to compete with the invasive species.

The predatory bacterium Bdellovibrio bacteriovorus is able to penetrate a gram-negative bacterium that has a slimy cell covering
jek_recluse [69]

Answer:

The order of bacterial structures that the bacteria would penetrate would be:

  1. Capsule.
  2. Lipopolysaccharide Membrane
  3. peptidoglycan
  4. Phospholipids Membrane.

Explanation:

A parasite like B. bacteriovorus faces some challenges in getting into a bacterial cell. This is because these cells have devices and strategies to prevent the entry of parasites and ensure the survival of the bacteria. The first challenge would be to penetrate the bacterial capsule. The capsule is a structure that is located around many bacteria. This structure is rigid, with sharp edges and thick thickness, which protects the bacteria from external agents. If B. bacteriovorus manages to go beyond the capsule, it will find a membrane, also thick, composed mainly of lipopolysaccharides, which will also provide protection and try to prevent the entry of the parasite. If this membrane is crossed, B. bacteriovorus will face another layer called peptidoglycan. This layer establishes itself as a cell wall, being very difficult to break. Some bacteria present one more layer after peptidoglycan, which is a membrane made by Phospholipids, which is highly selective and difficult to break, but is more fragile than the previous layers. Only after overcoming all these structures, the parasite will have access to the bacterial cel

Question 2 of 25
Dmitry_Shevchenko [17]

The sentence a Venus flytrap closes its leaves when its trigger hairs are stimulated is the best example of a living thing responding to its environment (option B).

<h3>What does characterize living organisms?</h3>

The main characteristics of living organisms refer to features shared by different life forms, which are essential to sustaining life, i.e. their metabolic activities in order to perpetuate across time.

One of the main characteristics that sustain life is the ability to respond to environmental stimuli. In this regard, it has been debated if this feature is the main characteristic that sustains life, but detractors of this idea state that it is not the main feature because viruses are able to respond to stimuli and they are not alive.

Therefore, with this data, we can see that the ability to respond to stimuli is one of the main features of living organisms.
