Answer:

e. horizontal transfer of genes from a marine bacterium

Explanation:

Horizontal gene transfer is the transfer of genetic material from one independent mature bacterium to another and creates new gene combinations in the recipient bacterium. It mostly occurs between the bacterial of different species and is responsible for the spread of new genetic traits such as antibiotic resistance, digestion of specific substances, virulence, etc.

Transfer of genetic material from the donor to host bacteria can occur in three ways: transformation, transduction, and conjugation. According to the given information, marine Bacteroidetes have enzymes required to digest porphyran and agarose. <em>B. plebeius</em> might have acquired the genes for these enzymes from marine Bacteroidetes by horizontal gene transfer. This resulted in its ability to digest the marine seaweed while its close relative species cannot do so.

Read each statement and decide what type of ecological interaction it describes.
Artist 52 [7]

1. Camouflage

2. Competition

3. Competition

4. Symbiosis

<h3><u>Explanation</u>:</h3>

The camouflage is defined as the property of the living organisms that make them to prepare their body to perfectly match with their surroundings so that they cannot be recognised by their hunters. This makes them survive more in an environment with full of competition.

The competition is an interaction between the organisms where in a particular environment, different organisms compete for a particular prey for their living. Here the theory of the survival of the fittest work.

The symbiosis is an interaction between two or more species which leads to benifit of both the species in their living. Here one species help other in a form and other species do the same. There's benifit for both in the interaction.

What would happen when an artificial K+ channel is inserted into an axon membrane at resting potential?Answer questions 1-4 by s
kap26 [50]

Answer:

<h2>K+ movement will be closed or blocked because the outside is more positive charged and K+ is a positive particle.</h2>

Explanation:

Resting potential of a neuron cell is a type of condition in which the neuron lives in rest that means there is no transmission of the impulse takes place. Such type of the condition occurs due to more negative charges inside the cell and more positive charges outside the cell. During this condition potassium ions are in higher condition inside the neuron and the concentration of sodium ions are high at outside of the neuron.
