Explain Darwin's theory of natural selection?
Ksju [112]
<span> "More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive." -https://www.google.com/search?q=Darwin%27s+theory+of+natural+selection&oq=Darwin%27s+theory+of+natur...
Basically what that means hun is that Darwin believed in a sort of adaption. That each generation was better adaptable to the environment and those who were healthier "survival of the fittest" would be more likely to survive. ^.^ Hope this helps!

yan [13]

Answer:

B) Bacteria: larger

Explanation:

Bacterias are unicellular beings and prokaryotes, bacteria are classified in the Monera Kingdom. There are thousands of known species that have different shapes, habitats and metabolism.

Some of these microorganisms are disease-causing (being called pathogenic), but there are also bacteria of great ecological importance (such as nitrogen-fixing fixers and food chain decomposers) and economic (used in various industrial processes).

The bacterial cell is prokaryotic, that is, the genetic material is dispersed in the cytoplasm and is made up of a circular DNA molecule called a nucleus. In some bacteria there may be an outer layer called a protein capsule that protects against dehydration, defends against bacteriophage attacks and phagocytes, and aids attachment to host cells.
