Mutualism, where both organisms benefit. -Commensalism, where one organism benefits while the other organism is not harmed.
shusha [124]4 years ago
7 0

Answer:

Explanation:

Mutualism and commensalism are both symbiotic relationships which means two distinct species lives in close association.

The main difference between mutualism and commensalism is that in mutualism both associating species get the benefit but in commensalism only one species gets the benefit but other species receives no harm and no benefit of association.

¿cuales son las ventajas y desventajas del uso de antibióticos?​
Firlakuza [10]

Answer: Ventajas: Los antibióticos han ayudado a controlar diferentes enfermedades, por ejemplo: la tuberculosis, la lepra, la escarlatina, el Sífilis, etc. Gracias a estos muchas personas han sido salvadas.                                         Otras de las ventajas es que los antibióticos pueden tratar ciertas infecciones con total eficacia.                                                                                        Desventajas: Una de las desventajas de los  antibióticos es la resistencia que generan estos ante las bacterias, esto se da por selección natural a través de mutaciones producidas por azar, pero presión selectiva a una población.                                                                                                                  Si los antibióticos están mal empleados, los antibióticos pueden generar mucho más daño.

What is one reason why many geologists did not at first accept the theory of continenal drift ?
Elodia [21]

Explanation:

Continental drift is the theory which states that the continents of the earth moved away from each other over a period of time. It is believed that this theory was opposed by many scientists because they stated that there weren’t enough evidence of mechanism to prove the drift between the continents.

However, it was also rejected because this theory opposed many ongoing geological theories like geosyncline theory, uniformtarism theory even when sufficient evidences were there to prove the continental drift theory.

What term is used to describe bacterial cells that can naturally take up dna from their environment?
Maru [420]
<h2>The correct answer is: Competent cells</h2>

Explanation:

  • Bacterial cells have the capability of incorporating foreign naked DNA or deoxyribonucleic acid fragments from the environment or the exterior of the cell to the interior of the cell. This process is known as Transformation.
  • The bacterial cells which are able to undergo transformation are called Competent bacterial cells.
  • Some of the bacterial cells are naturally competent like<em> Bacillus subtilis, Streptocossus pneumoniae</em> while others  like <em>Escherishia coli </em>need to be chemically treated to make them artificially competent.
  • In natural competence, the foreign DNA from the cell exterior is incorporated into the cell interior through specific protein complexes present in the plasma membrane of the bacterial cells.
  • In artificial competence, the negative charge on foreign DNA is masked by positively charged calcium ions (so that it is not repelled by the negative charge of the lipid bilayer of the bacterial cell plasma membrane) and then small pores are created in the lipid bilayer of the plasma membrane of the bacterial cells by giving a heat shock to the cells. This results in the uptake of the DNA by the bacterial cells.
