Answer:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.
Answer:
three risks that are associated with genetically engineered plants?
Three risks involved in genetically engineered plants include;
Resistance
Mutation
Explanation:
Over time plants resist genetically engineered process as a result of exposure to such measure over time which enable such plant to develop resistance over time and pass the traits to their offspring.
The right answer is pectinated muscles.
The right atria extends between the two cellar veins. It is of rounded aspect, but for the simplification of its description, it is assimilated to one cube having 6 walls:
Anterior wall
A lower wall
A posterior wall
A top wall
An inner or septal wall
An outer or straight wall: relatively thin, has muscle thickenings: pectinated muscles. This is the preferred route of choice for cannulations during cardiac surgery under extracorporeal circulation.
