Answer:

Gene flow

Explanation:

Gene flow describes the process where genetic information migrates to another population, introducing new alleles into the gene pool and increasing the variation in that population.

Having physical barriers would prevent this exchange of information. For example, two populations separated by a mountain range or body of water would have far less chances to interact and exchange genetic material. This would make it difficult for gene flow to occur.

Organism A has blunt teeth, while organism B has sharp ones. Identify the organisms on basis of their feed habit and give anothe
VikaD [51]

Answer:

- Organism A is most likely a herbivore

- Organism B is most likey a carnivore

Explanation:

Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.

- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.

Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.

- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.

Identify the MOST specific taxonomic level.
UNO [17]

Answer:

Species

Explanation:

Species is the most specific and basic taxonomic level of classification and also the basic unit of biodiversity. Species is defined as group of highly closely related organisms that mate or breed to produce fertile offspring. After species genus is specific, and mostly organisms names are identified by species names and genus names as in binomial nomenclature, all scientific names are derived from genus and species e.g. the scientific name of frog is <em>Rana tigrina, </em>here '<em>Rana</em>' is genus name that is always capitalized and '<em>tigrena</em>' is species name that starts with small letter but both are always written in italics or underlined.
