Drip method is one of the mainstays of sustainable agriculture because it : A. reduces soil erosion
Like the name said, Drip irrigation is designed to utilize the least amount of water supply by giving the water to the plant drip by drip. In this method, there is no flow of water that commonly caused the soil erosion (because the water flow cut out the soil little by little)
Answer:
the branch of science concerned with classification, especially of organisms; systematics.
Explanation:
Answer:
the population is polymorphic.
Explanation:
Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.
Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.
We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.
