Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).
Answer: In 1859 European wild rabbits were introduced into Australia so they could be hunted for sport. The proliferation of rabbits was the fastest of an introduced mammal anywhere in the world. ... Australia is home to at least 150 million feral rabbits, which continue to have a huge impact on our environment

Explanation:
Answer:
Postzygotic reproductive barriers
Explanation:
Post-zygotic reproductive barriers are the adaptations developed in the organism which occur after the zygote (fertilization product) has been formed.
The Post-zygotic barrier involves the hybrid inviability which refers to the reduction on the viability of the offspring and hybrid sterility or that is the production of the fertile reproductive barriers.
The production of mule by the mating of horse and donkey results in the infertile mule which is considered the mechanism of the post-zygotic barrier.
Thus, Postzygotic reproductive barriers are the correct answer.
The main signal in small intestine for pancreatic bicarbonate ion secretion is Secretin.
When food from the stomach with acidic medium enters duodenum(first part of small intestine) it stimulates the lining of duodenum cells to release the hormone secretin.
This hormone travels via bloodstream to pancreas and stimulate to it to release bicarbonate ions.Now these ions enter duodenum and neutralise the acidic medium.
This results in the optimum pH for the enzymatic action to take place thereby promoting final digestion of protein.
