Answer:
B.) Duplication
Explanation:
A.) is incorrect because deletions involve the removal of one (or more) nucleotides during the DNA replication process.
B.) is correct because duplication involves duplicating a nucleotide (or more) of the DNA strand. This results in repeated genetic material.
C.) is incorrect because inversion involves a section of DNA bein removed and reattached backwards during DNA replication.
D.) is incorrect because translocation involves a section of a chromosome being removed and added to another chromosome.
The temperate forest biome covers latitudes ranging approximately from the southern United States to southern Canada, while the taiga biome, also known as boreal forest, extends from the latitude of southern Canada to about 60 degrees north latitude. (see References 1, References 3) Thus, these two biomes are adjacent, which explains the many similarities between taiga and northern temperate forests. Both biomes have four distinct seasons, but the temperate forest climates cover a much wider range of temperatures and precipitation patterns. Taiga, in contrast, is reliably cold: most of the precipitation falls as snow, winters are severe and the growing season is short -- about 130 days compared to 140 to 200 days for temperate forests.
Light-dependent reactions
-takes place in grana-releases oxygen
light-independent reactions-fixes carbon dioxide-takes place in stroma-
Explanation:
Photosynthesis in plants takes place in two steps to produce glucose and oxygen.
These are:
Light-dependent: In this phase, the molecules required for light independent reaction are made. These are ATP and NADPH. The machinery required for this process is in photosystems, which absorb light in reaction centres and get ATP and NADPH produced. In this process, oxygen is released as a by product. It takes place in the grana of thylakoid membrane.
Light-independents also called as Calvin Cycle or dark reaction: This is the bio synthetic phase of photosynthesis in which glucose is produced by reducing carbon dioxide using the ATP and NADPH from the light reaction.
It takes place in the stroma of the (outside thylakoid membrane) of chlorophyll.
Three important steps of dark reactions are:
Carbon fixation
Reduction of carbon dioxide
formation of ribulose 1,5 bisphosphate.
