It should be noted that a cell simply means the basic building block of living things and the human body has million of cells.
<h3>
What Is A Cell?</h3>
Your information is incomplete. Therefore, an overview of cells will be given. Cells provide the structure for the body and take in nutrients that are used to perform specialized functions in the body.
A cell can also be defined as the smallest unit of an organism that has a nucleus. It should be noted that the size of a cell can be measured by using an eyepiece graticule.

Biologists think that endosymbiosis gave rise to mitochondria before plastids partly because: (All eukaryotes have mitochondria whereas many eukaryotes do not have plastids)
Answer:
C. They all use a cut and paste mechanism.
Explanation:
DNA transposons can go through a replicative or nonreplicative transposition.
The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.
The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.
Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.
A. The sun
Abiotic means fake or not living. Trees, grass, and people are living, also know as biotic. The sun is not living, it’s just a ball of hot gas, which is not living.
Answer:
B) Help produce oxygen
C) Help make foods
D) Help break down dead materials
Explanation:
B - Life on Earth <em>depends</em> on protists since they are the ones who supply us with oxygen.
C - Provide food to other living organisms in food chains/webs.
D - Even, recycle important nutrients just for other life forms to use (some protists may also be decomposers; as they also release nutrients into the environment).
