The genetic makeup of an organism at fertilization determines only the
- <em>Genes are encoded with different traits. Each of these traits carry different functions to the new offspring that is developing. ... The genes that an organism inherits can affect gene function. For example they can have a recessive gene for something thatmight affect them. I hope that this helps you out, have a fantastic day!!</em>
The answer is A. Organisms compete for limited resources. A is wrong because it has nothing to do with reproduction which is natural selection.
Answer:
Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.
Explanation:
It is very clear that a metal which is higher in activity will replace a metal having lower activity.
Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.
Residues of copper is a clear evidence of reaction
The chemical equation for this reaction would be -
Hence, option D is correct
Example of selective breeding: Cows that produce lots of milk. Selective breeding to create more useful varieties of animals and plants is a form of biotechnology that human beings have used for thousands of years. Biotechnology includes any use of science or technology to alter the characteristics of a particular breed or animal.
