Question

How does algae maintain homeostasis?

Answer 1

Dehydration-tolerance mechanisms always involve maintaining homeostasis during dehydration as long as possible by actively regulating the water status, and hence minimizing or repairing any damage as fast as possible. In contrast, desiccation tolerance consists of strategies to survive the complete loss of water.

Answer 2

Pathogenic Bacteria Form Biofilms

Explanation:

• Single-cell organisms are often concerned with regulating their environment. In a sense, homeostasis in animals is a similar concept. One group of your cells is attempting to regulate the environment of your other cells
• Intracellular parasites, whether fungal or bacterial, are often brought into lysosomes inside the animal cell, where most pathogens would be broken down. Successful intracellular pathogens are able to secrete compounds that neutralize the pH in the lysosomes, making it a compartment where they can hide and reproduce
• Drug efflux pumps could be seen as something approaching homeostasis in bacteria. Some bacteria are able to detect the intracellular presence of drugs and to pump out these compounds that are toxic to them
• Pathogenic bacteria form biofilms. These films are composed of layers of the same bacteria, linked to each other. These biofilms are hard to disrupt physically and cells that are not on the surface exist in an environment that is protected from drugs and the immune system
