Answer:
he relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.

The answer is; Early steps consume energy from ATP, and later steps store an increased amount of energy in ATP and NADH
In the initial stage (energy consuming), 2 ATPs and consumed to convert glucose to the high energy fructose-1,6 biphosphate. The fructose-1,6 biphosphate is later split into 2 glyceraldehyde-3-phosphate (G3P). In the energy-releasing phase, each G3P is used to generate 2 ATPs and an NADH are released. Therefore, there is a net positive energy of 2 ATPs and 2 NADHs.
The correct answer is letter a, it is because in wet drop method, it does not need to add water after placing the specimen because adding water before placing the specimen in the glass slide is already enough and after placing the specimen, a cover slip is the last step in finishing the method. That is why Johnny is not correct in doing the procedure.
1) We must ration out the oils because we will be running out before 50 years & we must have new technology to replace the Fossil Fuels.
2) If we allow the World's resources to be used as fast as they are then at some point we will run right out of that resource forever.
3) There should be someone to take responsibility for the mining and usage of the World's resources before its too late and it should not be too long before we reach the point.
One type of cell that contains half the genetic information of an individual is a S.PERM.
In sexual reproduction, for a zygote to be formed, two type of cells must come together,that is, an egg and a sperm. Each of these cells contain half the information that will be needed to form a new zygote.
