The genetic variation of organisms has three sources they are mutation, gene flow and sexual reproduction.
Explanation:
Genetic variation are caused by mutation , random mating, random fertilization and recombination between homologous chromosomes during meiosis.
It is a variation in alleles and genes, among the populations. There is a genetic variation within the family of closely- related individuals. If it is a neighborhood there are many families and there is also genetic variation among that group.
An exact genetic copy of the parent organism is produced in asexual reproduction. It only introduces the genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
I would agree with Kaylan because both fertilizers are indeed dangerous to the environment even though the natural fertilizer has the word “Natural” in front of fertilizer does not mean that it is completely environmentally free from all the chemicals they do have in the Natural Fertilizer.
Answer:
A. All lipids are insoluble in water.
Explanation:
Macro molecules are also called polymers, which are formed as a result of polymerization of molecules such as carbon, hydrogen and oxygen.
There are four types of macro molecules in the mammalian system which are
- lipids
- nucleic acid
- protein
- carbohydrates
Lipids are macro molecules that do not dissolve in water i.e. they are hydrophobic. they help in the formation of cell membranes and hormones in the body.
