1 answer:
Dmitriy789 [7]3 years ago

The energy of the electrons in NADPH are not sufficient for anabolic reactions such as CO2 fixation. These processes also require biochemical energy in the form of ATP. The process of photosynthetic electron transfer also generates a gradient of protons (H+) across the photosynthetic membrane (Figure: Proton Gradient).

New crust and hydrothermal vents forms at ridges formed at a ______________ boundary.
natita [175]

Answer:

Option B, Divergent Boundary

Explanation:

The tectonic plates moving around form the divergent boundary and at this boundary magma from inside the earth rises to form new crust on the lithosphere beneath the water. Most of the divergent plate boundaries are present below the water where they form oceanic spreading ridges (submarine mountain ranges). The process of formation of oceanic spreading ridges is volcanic.

Hence, option B is correct

AlekseyPX

Answer:

D. Both a and c are correct.

Explanation:

The tragedy of the commons is a situation in a shared-resource system where individual users, acting independently according to their own self-interest, behave contrary to the common good of all users by depleting or spoiling the shared resource through their collective action.

It damages our environment (plants, animals) and impacts local tourism. It is smelly and dirty, and carries germs, bacteria and viruses. Places with a high degree of littering see a decreases in property values, and are more likely to be the site of fires.

Pollution is a negative externality. Economists illustrate the social costs of production with a demand and supply diagram. The social costs include the private costs of production incurred by the company and the external costs of pollution that are passed on to society.

Blowing litter can cause automobile accidents as well as land and air pollutions
