Answer:
B. urbanization
Explanation:
In urbanizing stage, death rate quickly declined because of the improvements in agricultural aspect which goes down to food supplies, health care delivery, medicine improvements, and even the investments in sanitation and infrastructure which contributes to the increasing life expectancy of the people and lesser diseases which cause deaths. Though birth rates remain almost the same, but young population continues to grow because of the low death rate.
I'm not 100% sure which biology class you are in are you doing the moth activity? If so then I would believe that the light moth would be easier to see on a dark tree trunk
Answer:
Although they are not closely related, as vertebrate animals, they share some characteristics and belong to the same Phylum.
Explanation:
Tigers and goldfish belong to different Classes. Tigers (<em>Panthera tigris</em>) belong to the Class Mammalia, while goldfish (<em>Carassius auratus</em>) belong to the Class Actinopterygii. However, they both belong to the Phylum Chordata.
Chordates share particular characteristics, such as a dorsal neural tube, a notochord, a bilateral symmetry, circulatory system, amongst other features. They are divided into different groups of vertebrates as well: mammals, birds, amphibians, reptiles, and fish. And, according to evolutionionary studies, over 300 million years ago, the first vertebrates that lived on land (amphibians) evolved from a lobe-finned fish species, which eventually led to the evolution of mammals that adapted to terrestrial environments.
Therefore, even though goldfish and tigers may seem completely different, they share similar characteristics. Plus, they are vertebrates that belong to the same phylum.
Answer:
The order of development has been large brains, bipedalism, tool use, modern behavior.
Explanation:
A is not correct because the human ancestors had large brains before they become bipedal, which is not weird considering the fact that all primates have proprtionately large brains, even for mammals.
B is correct because the large brains were already a trait of the human ancestors, with the change of environment they developed bipedalism, with the further growth of the brain and anatomic changes in the fingers the humans developed tools, and last but not least came to modern behavior.
C is not correct because bipedalism occurred before the usage of tools.
D is not correct because the tool usage did not occur at the beginning of human evolution, but several million years later.
E is not correct because the bipedalism occurred later than the large brains, and the modern behavior came the last, not in the early stages.
Answer:
The career in marine biology that appeals to me the most is aquatic science. Aquatic scientists use comparative studies, long term data, models, and theory to address a myriad of questions pertaining to water: water movement, water chemistry, aquatic organisms, aquatic ecosystems, movement of materials in and out of aquatic ecosystems, and the use of water by humans. This sounds very compelling to me.
