Gene is the appearance or characteristics that are seen in an organism, It is also an organism's allele combination and a segment of DNA that is the basic unit of heredity

Explanation:

Gene is defined as a unit of heredity by which genetic information is transferred from parents to its offspring. The genes are present on the chromosomes as bead-like structures. Genes are made up of  DNA sequence which dictates specific protein to be made in organisms. Genes are responsible for all the inherited characters in an organism.

Compare the process of carbon fixation in C3 plants to that of C4 plants.
Gre4nikov [31]

Carbon fixation is the process in which plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.

Because different type of plants are located in regions with different conditions they are different types of carbon fixation.  Plants that live in arid regions need to conserve water, while plants that live in more moist conditions will not need to conserve water.

The carbon fixation in C3 plants is one-step process. An oxidation reaction occurs because of the enzyme RuBisCo.  During the oxidation some of the energy used in photosynthesis is lost in a process known as photorespiration.

Under which environmental condition would primary succession occur ​
astraxan [27]

Explanation:

Primary succession starts off with the modification of a previously unoccupied area along with increasing variation- this occurs in barren areas devoid of life like sand dunes, and lava flows. Communities in a primary succession include:

-barren rock

-bacteria and fungi

-mosses and lichen

Further Explanation:

Succession involves small scale changes within a community that occur repeatedly over the life of that community.

Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:

  • colonizing species exploiting uninhabited areas (Primary succession)
  • becoming a habitable and increasingly complex community
  • there is increased diversity of organisms (Secondary)

The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.

However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.
