Answer: Natural Selection is the (natural) process in nature whereby organisms (plants, animals, etc.) that are better adapted to survive and thrive in their environment, are more likely to survive in order to breed/reproduce and pass on their own genes and characteristics. These characteristics can be physical or behavioral.

Artificial selection is where man, instead of nature, determines which characteristics they would like to hone. In the case of crops, edible, tasty, easy to cultivate crops were chosen above harder to grow crops. Animals kept for meat and other products, were selected based on how much milk, wool, meat, etc. could be produced. Health was also a factor, as sickly animals are troublesome (and potentially unsafe to utilize their products). In the case of domesticated pets, let us consider the dog, originating from domesticated wolves. The more easily trained, protective, better natured wolves were chosen to continue to line of species and the undesirables discarded.

All of the following are periods off prenatal developments except
qwelly [4]

Explanation:

1. All of the following are periods of prenatal development except:       a.germinal

b.embryonic

c.fetal

<u>d.postpartum</u>

Prenatal development describes the 40 week period before a child’s birth and the processes that occur during that time during prenatal development. Cells containing genetic material called chromosomes determine all physical characteristics of an organism including biological sex, height  and eye color through expression of genes.

  • The germinal stage describes the process from conception through implantation which is approximately two weeks, and begins when an egg is fertilized by sperm to form a zygote.
  • The embryonic stage follows this until week eight of pregnancy; here the zygote divides into multiple cells in layers that determine systems like the nervous system; skeleton and respiratory system. The embryo travels through the fallopian tubes and implants itself in the lining of the uterus where blood vessels form the placenta.
  • During the fetal stage spanning from week 9 until birth,  differentiation,  formation of sex organs internal organs and sensory perception occurs. The fetus also undergoes major brain development to form psychological and psychosocial traits. Immediately following the birth of the fetus is called the postnatal period
