Capitolo 6, Problema 7

Obligate ___________ exist in salt ponds because of their ability to withstand high osmotic pressure.

Guida verificata passo dopo passo
1
Identify the key term related to organisms that thrive in environments with high salt concentrations, such as salt ponds.
Understand that 'obligate' refers to organisms that require a specific condition to survive, in this case, high salt concentration.
Recall that organisms adapted to high osmotic pressure environments are called 'halophiles', which means 'salt-loving'.
Recognize that 'obligate halophiles' are those that must live in high-salt environments because they depend on such conditions for their cellular processes.
Conclude that the blank should be filled with 'halophiles' to describe organisms that exist in salt ponds due to their ability to withstand high osmotic pressure.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Obligate Halophiles

Obligate halophiles are microorganisms that require high salt concentrations for growth. They thrive in environments like salt ponds where salt levels are extremely high, which would inhibit or kill most other organisms.

Osmotic Pressure

Osmotic pressure is the force exerted by solutes in a solution that draws water across a semipermeable membrane. High osmotic pressure in salt ponds causes water to move out of cells, so organisms must adapt to prevent dehydration.

Adaptations to High Salt Environments

Microbes in high-salt environments adapt by accumulating compatible solutes or using specialized proteins to maintain cell integrity and function. These adaptations allow them to survive and reproduce despite extreme osmotic stress.
