1) Generally speaking, bean plants have fewer than 100 nodules, soybean plants have several hundred, and peanut plants can have 1,000 nodules or more. Cut-open nodules from a legume displaying the reddish-pink colour of an active, healthy nodule.
2) Both of them have roots that extend far into the cup in an effort to find food to survive. Both of them have nodules.
3) The radish just occupies the cup's centre; the beans basically fill the entire space. not as many nodules as a bean plant.

Prokaryotes lack an organized nucleus and other membrane-bound organelles, the prokaryotic DNA is found in the central part of the cell called the nucleons, the cell size ranges from 0.1 to 5.0 in diameter, the cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shoe and prevents dehydration.
Answer:
L
Explanation:
The details tell us that the substance starts out and its atoms are "close together and cannot slide past one another." This describes a solid: liquids and gases' atoms can move freely, but solids' atoms cannot move. So we know that the substance starts as a solid.
That means the answer must be L or P, because the solid needs to change into something else.
Then the substance gains energy and it can fill its container. Well, this could be either gas or liquid! So it's a good thing that <u>only L is an answer choice,</u> because that means L is correct and the change is from solid -> gas.
Answer:
chromatin network or chromosomes
Because only then we had the technology (powerful microscopes) and techniques to observe the differences.
Hope it helps!
