I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm.

Answer:Archaea, Bacteria, and Eukarya
Explanation:
Answer:
The correct answer is - option b) 3Li .
Explanation:
Lithium that is occurring naturally have two isotopes that are stable one with an atomic mass of 7 and the other with an atomic mass of 6 both have the same atomic number.
In question 7(atomic mass) 3 (atomic number) is given and there is only two option have 3 atomic number with 3 b) 3.Li and d) 43Li. 4 atomic mass is not naturally occurring isotopes and as option b) has a no atomic mass so it would be the correct answer.
Thus, the correct answer is - option b) 3Li .
Answer:
density of the sediment
size of the sediment
velocity of the agent of erosion
Explanation:
Deposition can be defined as the process of building up of sediment from chemical processes because the forces which are responsible for transporting Sediment are no longer sufficient enough to overcome the forces of gravity which is why density of the sediment, size of the sediment as well as velocity of the agent of erosion tend to affect
The rate of deposition due to the fact that
Larger and denser particles are heavier and land first before, less dense particles which cause round pieces of sediment settle more quickly than flat pieces .
Hence,density of the sediment,size of the sediment as well as velocity of the agent of erosion will often affect the rate deposition.
