Answer:
This is an example of founder effect.
Explanation:
Founder effect may be illustrated as the loss of genetic variation in a novel small population originated from the original population. The concept was initially presented by Ernst Mayr. It can be seen that genetic diversity has got reduced in the population of iguana due to the result of the flood that has washed all the iguana without webbed feet into the sea.
The new population has got inclined from the small iguana population. Thus, the iguana population is regarded as an illustration of the founder effect.
Answer:
1.An example of Batesian mimicry is when the yummy viceroy butterfly mimics the orange and black coloration of the distasteful monarch butterfly. ... Wasmannian mimicry occurs when the mimic resembles it's host (the model) in order to live within the same nest or structure. For example, several beetles closely resemble ants
2.Orange and black Monarchs (Danaus plexippus) are among the most familiar and easily recognizable butterflies found in the vivarium. Bright colors and distinctive wing patterns can be an example of aposematism, also known as a warning coloration.

Answer:
Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.
Answer:
A glance of earth taken from space will depict it blue. This blue colour is actually water, the major part of the earth is covered with water. We need water for almost everything, for example- drinking, bathing, cooking etc and therefore we should know about the properties of water. 65 % human body is composed of water. Water is essential for the survival of life on earth. Water is distributed unevenly on the earth’s surface. It forms a major solvent and dissolves almost every polar solute. So let us have a look at its properties.
Physical properties of water : Water is a colourless and tasteless liquid. The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. This also leads to high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment etc. These properties form the reason for its significance in the biosphere. Water is an excellent solvent and therefore it helps in the transportation of ions and molecules required for metabolism. It has a high latent heat of vaporization which helps in the regulation of body temperature
Chemical properties of water: Amphoteric nature:
Water can act as both acid and base, which means that it is amphoteric in nature.
Example:
Acidic Behaviour: H2O(l)+NH3(aq) ⇌ H3O+(aq)+NH+4(aq)
Basic Behavior: H2O(l)+H2S(aq) ⇌ H3O+(aq)+HS−(aq)
Redox reactions:
Electropositive elements reduce water to hydrogen molecule. Thus water is a great source of hydrogen. Let us see an example in this case:
2H2O(l)+2Na(s)→2NaOH(aq)+H2(g)
During the process of photosynthesis, water is oxidized to O2. As water can be oxidized and reduced, it is very useful in redox reactions.
Hydrolysis reaction
Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.
