The correct answer is: D) H2O… CO2
Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
The phospholipid is arranged into a bilayer, it is a basic structure of all membranes. Each membrane composed of membrane proteins that activate the membrane to carry out its distinctive activities. Some proteins are limits only to the membrane surface, other have one region in membrane and domain on one o both sides of it.
Order level of the taxonomic hierarchy is more inclusive than a family, but less inclusive than a class.
Order is the level that lies between the Class and Family. The example of Class Mammalia can be considered which consists of orders: Order Chiroptera, Order Primates, Order Carnivora, Order Cetacea, Order Insectivora, etc.
Taxonomic Hierarchy is the arrangement of all the organisms on the basis of their similarities or dissimilarities with other organisms. In the decreasing order, the levels of the taxonomic hierarchy include: Kingdom, Phylum/Division, Class, Order, family, Genus and Species. This categorization is essential to understand about the organisms as well as their relation with other organisms.
