In which photosynthetic reaction is co2 reduced to form a carbohydrate?
a. light dependent
b. light independent
c. fermentation
d. krebs cycle

b. Light independent

Explanation: Photosynthesis is a process where carbohydrtes are formed with energy from the sunlight, in cianobacteria, algae and plants. This process has two steps:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
