Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

Answer:
1. Surface (substratum) is preconditioned by environment molecules.
4. Microbes attach and detach from the preconditioned surface.
2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.
3. Biofilm matures and some microorganisms escape to the plank-tonic state.
Explanation:
Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
Both dna and rna have four nitrogenous bases each three of which they share (cytosine adenine and guanine )
Answer:
How rocks change from one type to another and which processes are involved in rock changes.
Explanation:
We know that there are three types of major rocks. Those are: igneous, sedimentary, and metamorphic. The rock cycle describes how the three major rock types convert from one to another.
Changing in rocks happens as a result of natural processes that are taking place all the time. Most of the changes happen very slowly. Rocks that are in the deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them to another rock. Even at the surface, we may not notice the changes in the rocks.
Along with this, a rock cycle describes those process which involves in this rocks transformation process. It represents various environmental factors that are related to the change of the rock from one to another.
Sea urchins tend to have great camouflage because they sometimes carry algae and rocks on their shells.
<h3>What is camouflage?</h3>
Camouflage is a defense mechanism used by certain organisms to avoid predation or surprisingly attack their prey.
Different animals possess different camouflage mechanisms. For example;
- Chameleons change their color to that of their immediate environment
- Certain snakes hide in vegetations that blend with their skin color.
However, sea urchins are aquatic animals that tend to have great camouflage because they sometimes carry algae and rocks on their shells.
