Answer:
Active transport
Explanation:
The pumping of sodium ions out of the cell into the environment where there is a lower concentration is achieved through active transport. Active transport is the movement of molecules or ions against a concentration gradient across living cell membranes with the utilization of ATP. Active transport takes place through carries located in the membrane.
Answer: (B) shared, derived traits.
Explanation:
In phylogenetic systematics, which presents itself with a character that eventually changes in descent, and presents itself with variations, which subsequently convert in the next generations. In this way, the character presence is not unique to the ancestor, but also in all heirs, however with a possible variation. This new variation or new character state is recognized as a derived condition, arose from the change in the state of the ancestral character. A derived condition has the potential to serve as a determinant for defining a new group is called apomorphy. An apomorphy can be unique to a group and is called a case of autapomorphy, or when it is shared by two or more groups it is called synapomorphy.

Mucilaginous sheath. Cyanobacteria are microorganisms that have survived for a thousand years now. They process and create their food through the photosynthetic mechanisms they possess and this process also includes nitrogen fixation and other biogeochemical process that contributes to most cycles.
