Which one of the following statements is true? Monocot stems have scattered vascular tissue, whereas eudicot stems have vascular
ludmilkaskok [199]

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>

By what factor (how much) does the milli- unit differ from the centi- unit?<br> earth science
GarryVolchara [31]

Answer:

By a factor of 0.1.

Explanation:

Hello,

In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:

\frac{milli}{centi}= \frac{0.001}{0.01} =0.1

It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:

\frac{centi}{milli}= \frac{0.01}{0.001} =10

Regards.
