Which traits would Aristotle have used to classify sharks? Choose more than one answer.
Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
The traits that Aristotle would have used to classify sharks are :
Front with points ( hornlike )Front without points Sharks classificationSharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.
Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.

How is the epithelium suited for the substances ?
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.
