The level most commonly meant by the term biodiversity is the species level.
Answer:
C
Explanation:
The Calvin cycle occurs in three major phases:
1) Carbon fixation; which involves the reaction of CO2 with a phosphorylated Co2 acceptor called Ribulosebiphosphate(RuBp) as catalysed by Rubisco enzyme. Due to the instability of the formed six-carbon compound, it breaks into two molecules of 3-phosphoglycerate (PGA)
2) Reduction; The PGA is phosphorylated by ATP to form 1,3-biphosphoglycerate, which is then reduced by NADPH to form glyceraldehyde-3-phosphate (G3P).
3) Regeneration; The final step, which is very important for the continuity of Calvin cycle is the regeneration of the CO2 acceptor (RUBP). The molecules of G3P are rearranged into molecules of Ribulosephosphate(RuP) by series of complex reactions, which is then phosphorylated by ATP to form RUBP, ready to accept CO2 for the cycle to continue
Answer:
Explained
Explanation:
During Meiosis the Chromosomes line up or assort independently from one another. Therefore, genes located on each chromosomes are also segregate of one another. Therefore, the gene for seed color (G & g) will assort independent of the gene for plant height (T & t) , thus producing 4 different gene combinations of gametes,they are : GT, Gt, gT & gt.
What is a fossil?
Fossils are fossilised (petrified) remains of animals/plants. A fossil though, is only a fossil, when it is from a different geological era.
How does that relate to evolution?
Evolution and fossils are very related. When we scan the DNA of different fossils, we find that the DNA can be similar to living species we have today, which helps us trace back their origins.
Tracing back a species origins is not something we do just to see how that species changed along time. When we manage to make an evolutionary chart of a species, we know how they changed, what they changed, and maybe not more, but very importantly, when the previous species were extinguished. If we know when they were extinguished, we can find out what caused that extinction:
- A lack of adaptation.
- Lack of resources.
- Temperature changes.
- Increase of predators.
- Deadly migrations.
- Other natural disasters.
So, in other words, by studying one species, we can study our own planet.
