Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Explanation:
#6 is A. They are all composed of one or more cells.
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.

Answer:
<em>Monocot stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
Explanation:
Both monocots and eudicots belong to the plant's sub-division known as angiosperms. However, there are four distinguishing features between the two:
- Monocots have single cotyledons or seed leaves while eudicots have two.
- Monocots usually produce needle-like leaves with parallel veination while eudicots produce broad leaves with net veination.
- Root system in monocots is usually a tap root while it is fibrous root in eudicots.
- Floral parts in monocots are usually in multiple of threes while they are in multiples of fours of fives in eudicots
- Vascular bundles in the stems of monocots are usually scattered about while they are arranged in ring-form in eudicots.
<em>Hence, the only true one among the statements is that monocots stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
