Answer:
The question is incomplete, here's the complete question;
Which statements accurately describe the roles of decomposers in the carbon cycle? Check all that apply.
-Decomposers release carbon dioxide into the air as waste.
-Decomposers remove carbon dioxide from the air during photosynthesis.
-Decomposers break down the remains of dead plants and animals.
-Decomposers return carbon compounds to the soil.
-Decomposers use carbon to make food molecules.
The correct answer is;
Decomposers release carbon dioxide into the air as waste.
Decomposers break down the remains of dead plants and animals.
Decomposers return carbon compounds to the soil.
Explanation:
In the earth, all living things are made up of carbon. Carbon cycle is the process in which carbon travels from the atmosphere into living things in the earth and then returned into the atmosphere. Carbon is released into the atmosphere through processes like respiration, decomposition, combustion etc. The carbon cycle explains how carbon is stored, made available to living things and replaced on earth. Plants absorb carbon in the form of carbon dioxide from the atmosphere and use it to produce food (glucose) and release oxygen in a process called photosynthesis. When animals feed on these plants , the carbon is transferred to them and thus passes it along the food chain. During respiration, animals release carbon dioxide back into the atmosphere. When the organisms eventually die, the carbon from them is put back into the atmosphere by decomposers so that other living organisms can use it. Decomposers break down dead organisms , releases carbon dioxide through cellular respiration and enriches the soil with nutrients. The examples of decomposers are bacteria, fungi and worms. Bacteria decomposes most types of organic matter. Fungi are the main decomposers in the forest as they break down wood and the cellulose in plant cell walls. Decomposers are very important because they release carbon locked up in the dead organisms back into the atmosphere and without carbon dioxide in the atmosphere plants can not produce glucose and oxygen.
Answer:
<h3>Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.</h3>
<h3>At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.</h3>
<h3>They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).</h3>
<h3>A virus that infects bacteria is known as a bacteriophage, often shortened to phage.</h3>
<h3>The study of viruses is known as virology, and those who study viruses are known as virologists.</h3><h3 /><h3>It has been argued extensively whether viruses are living organisms.</h3>
<h3>Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.</h3>
<h3>They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.</h3>
<h3>A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.</h3>
<h3>Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.</h3>
The answer is the muscular system
Answer:
the type of molecule-destroying enzyme he used
Explanation:
Frederick Griffith and Oswald Avery were scientific researchers who discovered DNA. Frederick Griffith began the research and Oswald Avery continued his research in 1944 when they made the discovery of DNA. When Avery repeated Griffith's research the experimental variable in Avery's experiment was the type of molecule-destroying enzyme he used.
