Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
A dominant trait can be shown both when an organism is homozygous dominant AND heterozygous. Two different genotypes give the same visible result so a testcross is needed to be able to accurately say if the organism is homozygous dominant or heterozygous
10
Explanation:
The Ritcher scale is a logarithmic scale and it suggests that the number increases by a factor of 10.
One point on the scale differs from another by an order of 10.
- The Ritcher scale is used to measure the magnitude of earthquakes in a particular area.
- It is graduated form 1 to 10
- The magnitude of the quake increases as one moves from 1 through 10.
- This is because the magnitude of the quake actually increases by an order of 10.

Answer:
C. Desertification.
Explanation:
This is mainly caused by overgrazing and other human and natural activities in this areas. When desertification happens in a land area, it hampers the land ability to support life; affecting wild species, agricultural crops, domestic animals and people. Its negative effect includes famine of the inhabitants, also mass migration, as it can also cause extinction of some organisms or species.
