I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
Answer:
5. polycyclic
Explanation:
Polycyclic disease cycle produce secondary inoculum which results in the infection on same crop or other crops during vegetation seasons. See attachment to observe the cycle how it happens.
Answer:
Charles Darwin had concluded that these birds had somehow evolved to adapt based on the island they were on. Each island had different food sources so if these finches wanted to survive they had to change. Each finch adapted to their environment due to forcefully evolving to survive.
Explanation:
Answer:
The conditions that affect physical stability are heat, temperature, compression, pressure, and the molecular structure. The base of the intrusion is parallel to the rock layer beneath it.
Answer: B
Explanation: A closed system can be defined as a system that does not allow for an exchange of matter with its surroundings.
An estuary where fresh water and ocean water mix is not a good example of a closed system because fresh water and ocean water mix out in the open and matter is exchanged.
A living single-called organism such as phytoplankton does not constitute as a closed system because in order for the phytoplankton to be considered alive it needs to interact with its surroundings i.e light from the sun so photosynthesis (converting light energy into chemical energy to be used by organism) can occur. This also happens out in the open
A river that flows into the ocean does not fit into the closed system definition. This is because a river that flows into the ocean allows for itself (matter) to mix with that of the ocean in an open space (rivermouth).
Therefore option B is the answer because it fits the definition. A chemical reaction within the deep ocean organisms that allows them to glow happens within (inside) the organism, making this system closed, hence there is no exchange of matter with surroundings.
