The correct answer is A. Athletes
That is because of all the training and exercises they do every day so they have to have much energy to consume.
Bronchus are the two in number and forms left and right , so it will appear in lungs !!
1. An infinitely dense atom of matter explodes, releasing all matter in the known universe.
2. This matter clumps together forming rocks and dust; that which doesnt compact remains as gas.
3. The rocks and dust are pulled in to each other by their own gravity. These clumps get bigger and bigger, and form planets.
4. Gas and dust clouds, better known as nebulae, (sing. nebula) begin to react, clump together and generate heat. Stars are formed out of these nebulae (unsure of the process).
5. The stars, with their powerful gravitational pulls, drag in planets to form solar systems. This happens on a larger scale as well, as groups of millions of stars are formed into galaxies, huge swirling discs containing millions of stars each.
That's where we are today.
Alleles can be either dominant or recessive.
Dominant alleles show their effect even if the individual only has one copy of the genes, For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes ;although, with two copies you will still have brown eyes.
If both alleles are dominant, it is called co-dominance. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of co-dominance of the A and B dominant alleles.
Recessive alleles only show their effect if the individual has two copies of the allele. For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the 'blue eye' allele.
