Answer: D.  Everyone whose train connects with the yellow route may be affected.

Explanation: Having only one out of 40 trains malfunction seems like a small change in the overall system. However, this small change has large effects on the system as a whole.  Many people ride trains that connect to the yellow line. Many people will be stranded at these stations, and some people may try to take different trains than usual in order to get to their destination.

Kipish [7]

Answer:

One importance in breeding agriculture plants is to improve the plant's yield, resistance against diseases, and ability to survive in cold conditions.

<em>(I'm assuming the question is asking what the importance is of artifically breeding plants, not literally breeding next to some plants. that would be weird)</em>

Part B: Research (11 points) In part B you will be doing some research on desertification.
Goryan [66]
Okay so northern Africa and the Sahara desert is the best example of desertification.
2 ways humans have contributed to that is: 1) pastoral nomadism 2) little to no settlements to increase water supply 

how it impacted the environment: so now the environment there is sandy, only organisms adapted for those extreme environment can live there ex. camel, cactus, etc., 

how it impacted quality of life: quality of life diminished, not enough water to sufficiently feed the populations, people live in extreme poverty, people are moving away, and the climate is very dry and hot, pretty much not a place anyone would want to live

Most extinction is ________.
Maksim231197 [3]

An extinction event is a well-known and quick decrease in the biodiversity on Earth. Such an occurrence is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the rate of extinction surges with respect to the rate of speciation. In other words, this happens when species cannot adapt generally to the change in the environment. So the correct answer would be letter a.
