The answer is; B
This hormone cases growth at internodes. Elongation at these points causes the plant to grow taller because of the long spaces between the stem nodes. The hormones are produced at meristems of apical buds and roots of plants. It is named after a fungus that infects plants causing them to grow too tall and fall over.
Auxins promote apical growth while cytokinins delay senescence in plants.
I think is C in my opinion
Their reproductive isolation from each other is complete: False
They are unable to produce hybrid offspring upon interbreeding: True
They shared a common ancestor recently in evolutionary time: False
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
This characteristic is used for inserting the recombinant vector into the bacteria during the process of DNA cloning. <span>DNA cloning is a molecular biology technique (genetic engineering) that makes many identical copies of a piece of DNA, for example, gene. That target DNA sequence (gene) is inserted into a circular piece of DNA called a plasmid and introduced into bacteria via process called transformation.</span>
