Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)
In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
Answer:
The student who filled the table correctly was C)student 3.
Explanation:
The student no 3 noted the organisms to be :
<em>Bread mold: Decomposers</em>
<em>Koala Bear: Consumer</em>
<em>Mushroom: Decomposer</em>
<em>Oak Tree: Producers</em>
Bread mold is a fungus. It decomposes the bread to get energy from it.
Mushrooms are also decomposers. Almost,all type of fungi are decomposers.
Plants are always the producers in a food chain. So, oak tree is the producer.
Animals cannot make their own food. Hence, they are the consumers like koala bear above.
A star goes throgh different stages until it gets completely formed. The first stage is nebula. <em>Nebulae</em><em> are _</em><u><em>dust</em></u><u><em> and </em></u><u><em>gas</em></u><em>_ where _</em><u><em> </em></u><u><em>stars</em></u><em>_ can form.</em>
<h3>
Star Cycle</h3>
The star cycle is the sequence of changes that a star undergoes throughout its existence.
The evolutive stages of a star differ between an average star and a giant star.
However, the first stages of the cycle are shared by all of them.
<h3>What are the common stages in stars cycles? </h3>
Stars are born from the nebula that is the<u> dust </u><u>and</u><u> gas particles </u>condensation due to gravity effect in the interstellar clouds
It is a more advanced level of condensation.
Equilibrium between gravity and nuclear fusion helps the star keep stable as long as the fuel lasts.
Hence, according to this resumed introduction to stars cycles, we may say that<em> </em>
<em>Nebulae</em><em> are _</em><u><em>dust</em></u><u><em> and </em></u><u><em>gas</em></u><em>_ where _</em><u><em> </em></u><u><em>stars</em></u><em>_ can form.</em>
