Answer:

d. Electron transport chain

Explanation:

when reduced NAD and FAD brings hydrogen, it splits into electron and proton. Electrons flow through electron transport chain from higher energy level to lower energy level which releases energy and this energy is used to pump electron from mitochondrial matrix to intermembranal space. This hydrogen moves back into mitochondrial matrix through stalk particle having ATPase will produce ATP and combines with oxygen and electron to form water

Answer:

Explanation:

1. can generate energy – Both , In landfills methane gas is produced which is used to generate electricity, like wise heat energy produced in incinerator is also used for producing energy

2. emits toxins through combustion – Incinerators produce dioxins which is a dangerous chemical

3. drains liquids into the ground – Land fill, leachate is a common issue with all landfill site.  

4. releases greenhouse gases – Both, methane and other carbon gases are produced in both landfill and incinerators

5. requires a substantial amount of land – land fill site , needs a large land to dump the city waste

If you were studying the effects of climate change on the geographic ranges of species living in the mountains and your climate
Andrews [41]

A species that is habitat specialist and lives at the highest elevation.

Explanation:

An ecosystem consist of plants, animals as well as micro-organisms but due to climate change the plants as well as animals are in danger . The case that has been provided in the question where due to climate change the temperature rises as a result the species living at the highest elevation are in problem .

Due to rise in temperature the snow is melting and the sea water level is rising. The animals and plants adapt themselves according to the climate where they are residing but suddenly if climatic change take place they will be unable to survive.

The animals which are mostly affected due to climatic change are snow leopard, polar bear, giant panda.
