Answer:

The correct answer will be-

1. Autonomous cell specification

2. Cell determination

Explanation:

The multi-cellular organisms have evolved from the unicellular organisms by evolving the two related mechanisms involved in the formation of multi-cellular mechanisms which are- cell determination and specification.

Cell determination is the ability of the cell to determine its fate depending on the chemical detected by the cell in a different region of the embryo. The chemical activates a series of events in cell-like activates a set of genes and intra and intercellular communication.

The Autonomous cell specification is the ability of a cell in which the cell is able to differentiate to carry out a specialized function without receiving any external signals.

Thus, Autonomous cell specification and Cell determination is the correct answer.

Two mechanisms that must evolve in order to make multicellularity possible are:


• Specialization of the cells which reffers specialization in function(not all cells do exactly the same thing, otherwise they would just be a group of cells or a colony)


• Adhesion, communication and cooperation-requires that the cells coordinate their activities by sending signals to each other. They shoul work cooperatively to develop their multicellular "body".

4. An animal that relies on a digestive tract for digestion breaks down food bya. both intracellular and extracellular digestion
vivado [14]
The answer is b. An animal that relies on the digestive tract for digestion breaks down food via extracellular digestion. The digestive tract uses mechanical and chemical processes to digest the food. Extracellular digestion is a type of digestion that happens in an opening as part of a digestive system where the nutrients produced from digestion is transferred to the blood or other body fluids. The digestive tract serve as the opening.

Dislocation is complete displacement of a bone from its joint.

Luxation is complete separation of joints.

Sublocation generally return to its normal position without the help from orthopedic doctor.

larisa86 [58]

Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.

Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes  an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
