Answer:
An advantage to heterospory is endosporic gametophyte.
The endosporic gametophyte do permits for embryonic formation. It prompts it to have a reduced vulnerability to varying form of environments.
The second advantage that heterscopy could offer to plants is ensuring of a well apportioned nutrient filled environment.
The well apportioned nutrient filled environment is formed as a result of the megasporangium been adhered to the sporophytic plant body. This sees to promote a good formation of the embryo.
A further advantage of heterscopy is the aftermath of fertilization.
This integument is hard as it is necessary to preserve the female gametophyte and embryo.
The correct answer is phospholipid / lipids.
All of the pairs represent the combination of macromolecules with their basic units.
In the case of lipids, basic building blocks are free fatty acids, not phospholipids. Phospholipids are a class of lipids composed of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group which are joined together by a glycerol molecule.
Answer:
2 DNA molecules that are identical from each other
Phospholipids consist of glycerol, phosphate group and two fatty acid chain.
Communication refers to a state when one animal conducts information to another animal making a certain type of modification in the animal, which acquires the information. Animals generally communicate using signals that may involve visual, auditory or sound based; chemicals involving pheromones, and others.
A pheromone refers to a discharged chemical signal used to stimulate a reaction in another individual of the similar species. Pheromones are generally common among social insects, like bees and ants. It is used to fascinate the opposite sex, mark a food trail, raise an alarm, or to stimulate other composite behaviors.
This kind of communication plays an essential role in natural selection. It helps in obtaining mates, establishing defending or dominance territory.
