Decomposers break down dead animals and plants. They usually benefit producers by releasing nutrients back in the soil.
Answer:
I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>
Explanation:
I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.
I found rods, and some are gram positive and long. They others are gram negative and very small and short.
The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>
The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
Answer: muscle contraction of sustained force resulting from repeated action potentials. (Option A)
Explanation: Tetanus is also called physiologic tetanus. Tetanus refers to the contraction of the muscle, which is established when the motor nerve that supply nerves to a skeletal muscle produces action potentials at a very high degree.
However, tetanic contraction is usually a normal process (such as when carrying a heavy box). Also, muscles can be shorten, lengthen or remain constant length during tetanic contractions.
The correct answer would be D) decomposers. Decomposers do just what they're named for. Decompose things. They break down dead plant and animal material, gaining nutrients from it, while releasing CO2 into the atmosphere.
