The position of the diver is described as "below a certain point"; therefore, the reference point must be above the diver. For a diver in the middle of his dive, the bottom of the pool, the other swimmers and the far side of the swimming pool are likely to be below the diver, or at level with the diver at most. Out of the options, the only point of reference that is likely to be above the diver is B. the diving board.

What are enterocoelous and schizocoelous organisms?

Mars2501 [29]

Schizocoely is a process by which some animal embryos develop while splitting the mesodermal embryonic tissue. On the other hand, enterocoelous was formed in which the coelom forms from pouches "pinched" off of the digestive tract.

Describe how a function of fats and oils is similar to a function of carbohydrates

Anna007 [38]

They store energy for the body cells with the difference that carbohydrates give the cells short-term energy while lipids give them long-term energy, meaning it takes more time for that energy to be lost

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

d.postpartum

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
