Answer:
i believe the answer is C
Explanation:
The conclusion from this graph is the enzymes lowers the energy of activation for this reaction. Therefore, option (C) is correct.
What do you mean by activation energy?Something that reduces the activation energy is called a catalyst. An enzyme is its biological name. Without being consumed, the catalyst speeds up the rate of the reaction.
By reducing the amount of energy required for reactants to combine and react, enzymes typically reduce activation energy. For instance: Reactants are brought together by enzymes so that they do not have to move around until they randomly collide.
Removal of reactants from the solution state, also known as desolvation. weakening the bonds between the enzyme and the reactants.

Describe natural selection
Answers
Answer:

Explanation:
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?
Answers
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 is the epithelium suited for the substances ?
Answers
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.
