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.
This is refered to as the chemical symbol. It is derived from the Latin name for the element which is why some elements like potassium (K) and sodium (N) have symbols different from their name on the periodic table.
B. Data Analysis.........
Answer:
AIt removes H2O from the atmosphere during glycolysis.
Explanation: It removes H2O from the atmosphere during acetyl CoA formation. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. Thats so easy :D
