directional selection example

The selectivity of a catalyst is its ability to make a reaction proceed in a particular direction to yield a particular product. This aspect of a catalyst can be well understood with examples. Example 1: The reaction of CO with H 2 yields different products..

It is a process of selective improvement of a crop. In selection, a plant is selected based on its genotypic and phenotypic characters in order to improve some of its characters in its next generatio..

Selection is an important technique in plant breeding. It involves picking the healthiest and the best ones out of the entire crop and reproducing them under controlled condition..

It is a process of selective improvement of a crop. In selection, a plant is selected based on its genotypic and phenotypic characters in order to improve some of its characters in its next generation. Natural selections have occurred in many crops, where som..

What shall be the most important objective of selecting sample from a population? => Sample selection shall be cost saving. or Each subject in the population shall have an equally likely chance of being selected. or Maximum number of samples shall represent the populat..

Select the correct statement/statements. 1. A line is a set of points that extends in two opposite directions without end. 2. Lines of different sizes have different thickness. 3. A line is of finite length 4. A line is a straight one-dimensional figure having no thickness. => 2..

Desirable plants are selected purely based on phenotype and pooled. They are allowed to be grown in mass in next generation. Further selections are made in 3-4 such generations to consolidate desirable characters by ignoring plants with undesirable character at each selecti..

Optically active adsorbents can selectively adsorb some other optically active substances. For e.g., Henderson and Rule in 1939 used dextro-lactose as an adsorbent to separate active constituents of racemic campho..

Darwin believed that nature selects only those individuals, which have favourable variations and thereby have competitive advantage over others. This process is known as natural selection. The members of any particular species can develop and survive only when they are able to ..

As the nephric filtrate moves in the nephron towards the collecting tubule, about 99% of water, whole of glucose and amino acids, most of the Na + and Cl, some urea and uric acid are reabsorbed back into the blood. This process by which only useful substances are reabsorbed from the nephric filtr..
