Answer:
Both
Explanation:
Most ant species are generalist feeders, and only some ground-nesting and ground-foraging species are strictly predators. Ants are central-place foragers (with the exception of army ants during the nomadic phase) that may use different foraging strategies.
Answer:
c. fittest descent with modification
Explanation:
Evolution can be defined, in a nutshell, as the process of variation and adaptation of populations over time, and may even cause the emergence of new species from a pre-existing one. In short, evolution is the process that gives rise to a fittest descent with modification. Thus, the great diversity of organisms present on our planet can be explained through this theory.
As we study evolution, we realize that the life forms we know today are not the same as those that lived thousands of years ago. This means that species have an evolutionary history and that many changes happen to them until there are the characteristics we observe today.
Species, therefore, are not fixed, have undergone changes throughout their history on the planet and continue to change. Man, for example, did not appear on earth as we see today, as there were several ancestral species.
The type of lipid that serves as one component of cell membrane is phospholipids.
The ability of the kidneys to
concentrate urine is dependent on the maintenance of an osmolarity gradient
between the interstitial fluid of the cortex and the medulla. Renal concentrating
ability can be measured in the laboratory by assessing the specific gravity of
the urine produced.
