Explain how seasonal fires benefit grassland ecosystems

Biology
1 answer:
Gemiola [76]3 years ago
5 0

Answer:

Fire is a natural part of the grassland ecosystem and helps maintain its health and vigor. It warms up the soil and reduces the leaf litter that accumulates each year, allowing sunlight to penetrate. ... After a fire, blackened fields quickly revive with new, green grasses and abundant, showy wildflowers.

What is the basic difference between simple diffusion and facilitated diffusion across a cell membrane? hints?
Licemer1 [7]

Simple diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration. Substances that move by simple diffusion are able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally small and neutral, as large or charged particles cannot cross the phospholipid bilayer. Some examples of molecules that move by simple diffusion are carbon dioxide and oxygen.  

Facilitated diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration with the aid of a membrane protein. Substances that move by facilitated diffusion are not able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally large and/or charged. They therefore travel through a protein channel in the cell membrane along their concentration gradient. Some examples of substances that can move by facilitated diffusion are glucose, sodium ions and chloride ions.  

The similarities between facilitated diffusion and simple diffusion are:  

They both involve the movement of a substance across a cell membrane along its concentration gradient (from an area of high concentration to an area of low concentration).  

They are both examples of passive transport, as neither requires energy from the cell to move the substance across the membrane.

Are the counts of blue crabs in Maryland accurate for 1991 and 1999?
kirill [66]
The population of blue crabs will be difficult for the scientists to count because of unreliable ways and natural phenomenon or occurrence that causes the water's temperature to rise. According to climate reports, year 1999 have warmer temperature and this probably caused the blue crabs to be active, but on year 1990 female blue crabs sustained a normal quantity of production of their species. Thus, the estimated count of population of blue crabs is probably more accurate in year 1990 than year 1999 because of the stable production of the female crabs.

Systems that use massively parallel systems of processors whose architecture is based on the human neuron structure are called
sashaice [31]

Answer:

Neural networks

Explanation:

The neuron is the structural and functional unit of the nervous system. The neuron is also known as a nerve cell. The neuron is the largest cell of the body that helps to communicate or transmit signals. A neuron has an axon body, dendrites, and terminal region. The transmission of the signal from one neuron to another through the axon terminal.   Large numbers of neurons are present in the human body system that coordinates the whole body system. Neural networks contain a massive amount of neurons whose architecture is based on neurons. So, the correct answer to the given question is neural networks that use massively parallel systems based on neurons.
