D. a niche is an organisms "job"
Answer:
A selective pressure is any reason for organisms with certain phenotypes to have either a survival benefit or disadvantage.
Explanation:
The three foremost forms of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism)
C4 flowers are so-called because the primary manufactured from CO2 fixation is a C4 natural acid, oxaloacetate, shaped by way of the carboxylation of phosphoenolpyruvate (PEP) by way of PEP carboxylase. The oxaloacetate is converted to other C4 acids (malate or aspartate) and transferred to the packaging sheath.
Calvin cycle is the main pathway of carbon fixation in vegetation, algae, and cyanobacteria. The opportunity pathways of carbon fixation are the Reductive citric acid cycle in microorganisms. 3-hydroxypropionate cycle in bacteria and archaea.

Answer:
Heterojunction or having two identical alleles of the same gene.
Explanation:
A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials.
