Insulin and glucagon are the hormones that cause blood glucose (blood sugar) preserved in a narrow range. The pancreas serves as the central part of this process. Secreted by the pancreas are both insulin and glucagon. Determined by the production of insulin and glucagon, people can find out whether someone may have diabetes, <span> hypoglycemia, low blood pressure, etc. Insulin or glucose can be prescribed to victims of those listed issues, it is mostly used to balance out the level of glucagon and insulin to try to stop the problem.</span>

Name two primary decomposers and describe their function in the recycling of life materials 125 words.
Sloan [31]

Bacteria and Fungi  are the two primary decomposers

Explanation:

<u>Bacteria: </u>Bacteria are known as microscopic single celled organism. Their existence is between inside as well as outside the organism. The use of bacteria is in medical and industrial processes. They are first organisms in earth. Bacteria can survive in worst condition. There are huge number of bacteria. So, it is classified according to their structure and shape.

The life cycle of bacteria can be divided into log phase, lag phase, the stationary phase and Death phase. In lag phase bacteria don’t grow they produce amino acid and protein and make copies of DNA. They make themselves ready for division. In log phase bacteria rapidly multiply itself through binary fusion. In the stationary phase the growth of bacteria is dwindles because of lack of space and accumulating waste. The last phase is death phase where bacteria loss its ability of reproduction.

<u>Fungi:</u> Fungi is same like bacteria play vital role in ecosystem. They are also decomposer. The first way of fungi life cycle is based on spore phase. They begin with haploid. They have one copy of all their genetic material. The second stage is mycelium stage where fungi reproduce asexually.

Why can information only pass in one direction across synapse?? pls help !!
klio [65]
A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport.
In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the way down a nerve track, and are not connected, but have tiny gaps between them and the next cell. These tiny gaps are called synapses.
When you get a nerve firing, you have probably heard that it is an electrical impulse that carries the signal. This is true, but it is not electrical in the same way your wall outlet works. This is electrochemical energy. Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. When the neurotransmitter hits the receptor on the next cell in line, it signals that cell to begin a firing as well.
This will continue all the way down the length of the nerve track. In a nutshell, a nerve firing results in a chain reaction down the nerve cell's axon, or stemlike section. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. You can think of it as a line of gunpowder that someone lit, with the flame traveling down the length of it. Common electrical power is more like a hose full of water, and when you put pressure on one end, the water shoots out the other.
Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.

Scorpion4ik [409]
A because osmosis will act to balance the concentrations of water inside and outside the cell. As this happens, sugar outside the cell will dissolve into the water and be moved across the cell membrane with it into the cell. This continues until the concentrations are equal.
