analogous structures

The right answer is analogous structures.

It is nevertheless interesting to note that several years before, a competition took place rather quickly between two types of mammals: the placentals and the marsupials, the Evolution having given in each of these two groups also armed individuals as we will see it next (We speak then of parallel evolution, that is the acquisition of similar characteristics in two species occupying the same space, not to be confused with a convergent evolution which gives identical attributes to two populations existing at times or in different ecosystems).

This is formed as a waste product in photosynthesis and used as a reactant in respiration.
mihalych1998 [28]

Answer:

Oxygen

Explanation:

Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.

A male bison charging another male bison is an illustration of which behavior?.
alukav5142 [94]

Bison are big mammals that belong to the family Bovidae. Male bison charging each other shows the competition among organisms of the same species.

<h3>What is the competition?</h3>

Competition is the ecological relationship between the organism of the ecosystem that can be positive, neutral or negative. It can be between species or among the member of the species.

Two bison fighting each other shows the competitive relationship between both of them as they both belong to the same species and can fight for territory, food, resources, reproduction and many others factors.

Therefore, the Bison charging shows competitive relationships among the same species.

Learning objective: 12.08.05 describe the initiation and propagation of depolarization and repolarization.
denis-greek [22]
Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.
