Answer:
RNA is a single-stranded nucleic acid. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine. There are many different types of DNA RNA is single stranded RNA forms a double helix.
Explanation:
Answer:
Transpiration is loss of water from the surface of leaves in the form of water vapour while guttation is exudation of water from the surface of leaves in the form of drops. Transpiration takes place through stomata while guttation takes place through hydathodes.
A function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set while place is a specific area or region of the world, a particular city, country. A building or area that is used for a particular purpose. A building, part of a building, or area that is used for shelter.
Explanation:
Protein Function may be terminated, disrupted, destruction of both the secondary and tertiary structure through the process called DENATURATION. Denaturation process does not break the primary structures since the link or sequence of peptide bond are greatly hold by Hydrogen bonding.
Answer:
Ecological tolerance refers to the ability of an organism, or animal to be able to adapt and survive changing environmental conditions.
The combination of factors that would result in an island community with the lowest ecological tolerance would be option B Introduction of invasive species, increased deforestation because with the introduction of invasive species, there would be more competition for natural resources such as food, water, sunlight; and with increased deforestation, there is greater chances of soil erosion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.
The reptile population decreases as arthropods decrease with their habitat
Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.
