Answer:
The answer is the 2nd trophic level.
Explanation:
Primary consumers get only 10% of the energy produced by plants that they eat. The higher you go up on the trophic scale, the less energy there will be.
Answer:
Since Yellow is dominant over green then almost all of the children will have yellow faces. The punnet square below will show what the offspring will have but my guess is
50% will have yellow faces
50% will have both yellow and green
1% will have a green face
But since Yellow is dominant over green the 50% of both colors will mostly show a yellow dominant.
I apologize if my drawing looks messy.
Hope this is correct
Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .

Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.
