The ability to detect and respond to changes in
environment.
Is the removal from organisms of toxic materials
and substances in excess of requierements.
The taking in of materials for energy, growht and
development.
Growth refers to
The process of making more of the same
organism.

A (a) is a group of organisms that can reproduce to produce a fertile offspring.
Some characteristics of the species are:
When they cannot look similar or equal to each other, they can not reproduce.
They can reproduce between them to
produce fertile offspring.
The members of species resemble to each
other very close in appearance.
They may have variations in the appearance,
but they continue being so similar.For
example; Humans, Cats and Dogs.

The Whittaker five-kingdom scheme is a scheme that allows to fit the organisms in their respective group. There are five major groups that are called "kingdoms", choose them:
Animal
Plant
Fungus
Prokaryote
Proctist
Keeping in mind the plant kingdonm, answer:
The plant kingdom is divided in:
Red, brown, green algae, bryophytes and vascular plants.
Red, brown, green algae, liverworts and mosses.
Red, brown, green algae, conifers and flowering plants.
According to cell structure, which is the area between the nucleus and the cell membrane?
Mitochondrion
Cytoplasm
Nuclear membrane
Osmosis
According to cell structure, we can find Lipids and Proteins like enzymes in the cytoplasms. Enzymes are important because:
They control the rate of the chemical reactions which take place in the cell.
They are used to build up the cell
According to cell structure, we can say that cell membrane has:
Selective permeability
Not permeability
Total permeability
According to cell structure, some of the function of the nucleus, are:
To regulate the chemical changes in the cell.
To control the type and quantity of enzymes produced by the cytoplasm.
To control cell division.
According to cell structure,plant cell differ from animal cell in 3 main structures, they are:
Cell wall
Cytoplasm
Plastids
Vacuole
Cell membrane
Cells are specialized according to the place where is located in the organism and its function. The oder od the levels of organization in living organisms, is:
Cell, Organ, Tissue, Organism, System.
Cell, Tissue, Organ, Organism, System.
Cell, Tissue, Organ, System, Organism.
Cell, Tissue, Organism, Organ, System.
