Biology
1 answer:
garri49 [273]3 years ago

There are microorganisms that are able to live in extreme environments under adverse conditions of pH, temperature and salinity. These microorganisms are classified as extremophiles.  Within the group of extremophiles there are halophilic bacteria, which are those capable of living in extremely saline environments.

One biological factor that all living things are subject to suffer from is osmotic pressure. Halophilic microorganisms have developed mechanisms to adapt to saline environments where osmotic pressure acts with great intensity on individuals. These bacteria change the chemical composition of their membranes and also accumulate osmoprotective compounds in their cytoplasm to compensate for osmotic stress.

State one factor, other than the tilt of the Earth’s axis, that causes seasons to change on earth.
3241004551 [841]

Answer:But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly.Sep 23, 2019

Why is it important to have both negative and positive feedback loops in the body
ELEN [110]

Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.

The principle of competitive exclusion means that A) niche subdivision can occur. B) a niche can be shared by two species. C) co
nignag [31]

Answer:

C

Explanation:

When two species share a common niche, then one is bound to exclude the other. This is due to the stiff competition for resources. The species with a slight advantage in acquiring the resources will edge out the other species from the environment. This has been demonstrated by George Gauss using two Paramecium species grown in the same media in the lab. <em> P. aurelia</em> outcompetes <em>P. caudatum</em>
