Answer:
Prokaryotes are surrounded by a _<u>plasma membrane</u>_that regulates the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule bateria, which increases the ability of pathogenic bacteria to cause disease.
Explanation:
Procatyotic cells do not have a nucleos that surround the genetic material, but ther do have a plama membrane that regulates the entry and exit of materials trough the cell. Also the capsule bacteria is a layer that is outside de cell and can cause a disease.

B: The birds in the two populations have different mating behaviors
Answer:
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.
