Answer:
C. Joining of self-replication molecules into protocells.
Explanation:
For the origin of life, at least three conditions are needed.
- there must have been a supply of replicators, that is, self-replicating molecules.
- copying of these replicators must have been subject to error through mutation.
- the system of replicators must have required a continuous supply of free energy and partial isolation from the general environment.
The radiation received from the sun on the early earth must have fulfilled the requirement of mutation. The mutation is necessary for bringing variation in the genetic material thus driving evolution. To protect the self-replicating molecules from the external environment and to keep them together, the molecules must have been enclosed in a membrane barrier, which should be selectively semipermeable, to facilitate the exchange of molecules.
A. energy, because plants, for example, are organisms which don't require blood. And humans are organisms that don't require soil. But all organisms require some variety of energy in order to live
Answer: Carnivores have unique characteristics of their jaw articulation, or the joint between their upper and lower jaws, which enable them to more.
Answer:
it has partial charges
The hydrogen gives a positive partial charge
The oxygen gives a negative partial charge
Oxygen is way more electronegative than hydrogen therefore the molecule will be polar.
