Answer AND Explanation:
In the process of succession, the species in an area will gradually change. Each species is adapted to survive and competes with other species under specific sets of environmental conditions. If these conditions change, then the existing species will be replaced by a new set of species which are better adapted to the new conditions that have evolved.
This process helps an ecological community to undergo a predictable change following the initial colonisation of a new habitat. The succession that occurs in new habitat uninfluenced by pre existing succession is called primary succession, where as succession that follows disruption of a pre existing community is called secondary succession.
Answer: A) an abnormally large number of collagen fibers and relatively few blood vessels at the repair site
Explanation:
The scar tissues are the thick fibrous tissues typically the collagen fiber that have the role of replacement of healthy tissues after the injury has taken place to initiate the recovery process.
The scars are produced as a biological process at the site of wound repair on the skin. The scar develops on the superficial surface of the skin due to external injury. It is a natural healing process.
There are few blood vessels that can be found at the site of repair along with the collagen fibers.
Yes the mitochondria is essential for both plant cells and animals cuz it’s the powerhouse of the cell
Answer:
Photorespiration
Explanation:
RuBisCo is the enzyme that catalyzes the first reaction of the Calvin cycle which in turn is a rate-limiting step. Photorespiration is the process during which the enzyme RuBP carboxylase/oxygenase (RuBisCo) catalyzes the reaction between oxygen and ribulose 1,5-bisphosphate to form 3-phosphoglycerate and 2-phosphoglycolate.
These two products are useless for the metabolism of cells. Photorespiration occurs since the RuBisCo enzyme has an affinity for both CO2 and oxygen. When CO2 is not available, as it occurs when plants close stomata during hot dry days to prevent water loss, photorespiration takes place. Therefore, stomatal closing in C3 plants to prevent water loss promotes photorespiration.
