What is the effect of a negative feedback mechanism?
A negative feedback system is what occurs most commonly in your body systems. These keep everything in a homeostatic state.
Which bacteria live in soil and fix nitrogen as part of the nitrogen cycle?
Leguminous plants contain symbiotic bacteria called Rhizobia within nodules root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilise the soil.
Is thermoregulation in humans regulated through positive or negative feedback systems?
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
How do animals obtain their nitrogen requirements?
Nitrogen is found in all living systems as part of the makeup of biological compounds. Animals obtain the nitrogen they need by eating plants, or by eating other animals that have eaten plants.
How is nitrogen essential?
Nitrogen is essential to growing plant and ammonia (NH4) is the main constituent of fertilisers. Most plants cannot make their own fertiliser but the legume family (peas,beans, clover) are very important because their roots contain nodules which contain Nitrogen fixing bacteria. In crop rotation systems these plants are ploughed back into the soil at the end of the growing season in order to improve soil fertility
How are aquatic systems monitered?
it rains
What are tiny floaters in aquatic systems?
Plankton
What are the internal causes of supply chain disruption?
Breakdown of information sharing systems
How do human activities threaten aquatic systems?
POLLUTION!
What are some processes that are part of habitat systems?
they are aquirum aquatic
What is the difference between aguatic and terriestal?
It is not easy to compare terrestrial and aquatic systems because there is such on the similarities and differences between terrestrial and aquatic ecosystems.
What negative effects is brought by the missionaries in the Igbo village?
Some negative effects of missionaries in Igbo villages in Nigeria include cultural imperialism, the disruption of traditional belief systems and social structures, and the loss of indigenous languages and customs. Missionaries can also contribute to conflicts within communities by challenging traditional authority and beliefs.
How can nitrogen be used?
nitrogen can be used for cooling computer systems and for fertilizing plants in a certain way
Bacteria are often thought of in negative terms but they are essential for life on Earth Describe the roles of bacteria as decomposers nitrogen fixers in digestive systems and in bioremediation?
By the breaking down of food in the digestive system.
What has the author Ronald Francis Walters written?
Ronald Francis Walters has written: 'Collisional de-excitation rates for the first negative and second positive systems of nitrogen' -- subject(s): Physics
Why herbivores need nitrogen?
Herbivores need nitrogen because it is essential for their metabolic systems and cellular structures.
Can you use nitrogen in AC?
All Heating, cooling, and refrigerationtechnicians use nitrogen. Nitrogen is a noble gas and prevents copper pipes from oxidizing while brazing. It is also used to check systems for leaks. Leak testing with nitrogen can save loss of expensive refrigerant which is illegal to vent to the atmosphere. It's all so a dry gas containing almost no moisture so it can help to purge moisture from system that contains moisture. That being said, nitrogen can not be used in a operational systems. Home AC systems and refrigeration systems can not use nitrogen to cool. It will damage the compressor. Also onlylicensed techs should work on AC systems.
