Answer:
D) epithelial tissue
Explanation:
The exchange surfaces of the organisms are the site for an exchange of substances or gases. These surfaces mostly lie within the body and protect the exchange tissues. The exchange surfaces of multicellular organisms are lined with epithelial tissues. These tissues have tightly packed cells with little or no intercellular spaces. The epithelial tissues serve to protect the exchange surfaces. Sometimes, these epithelial linings are modified to perform an additional function. The exchange surfaces are finely branched or folded to have a very large area. The digestive, respiratory, and excretory systems all have such exchange surfaces.
Answer: The generally accepted parts of recent cell doctrine include: All known living things are made of one or more cells. All living cells arise from pre-existing cells by division. The cell is that the fundamental unit of structure and performance all told living organisms. I hope this helps :)
A minimum stream velocity <span>needed to keep a 6.4 cm diameter particle in motion must be 100 cm/s.
It can be concluded from Hjulstrome curve, a graph used to determine whether stream will transport, erode or deposit particles. The faster is the current, the heavier particles it could transport.</span>
Answer: 3- mutation, natural selection, migration
Explanation:
1-genetic drift, mutation, natural selection
2-mutation, founder principle, bottleneck effect
3-mutation, natural selection, migration (gene flow)
The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
