Because there is genetic variation among the newly reproduced organism.
Sperm cell (gamete) in humans = 23
Zygote in monkeys = 48
Zygote in humans = 46
Egg cell (gamete) in monkeys = 24
In osmosis, water always moves toward the HYPERTONIC solution: that is, toward the solution with the GREATER solute concentration.
Note: water moves according its own concentration gradient. A solution with greater solute concentration has a lower water concentration. Hence water moves towards it
Answer: Annelida
Leeches are soft bodied segmented parasitic worms. They belong to the phylum Annelida. They are hermaphrodites which means they exhibit sex organs of both male and female.
The characteristics which are found in leeches which group them into Annelida are:
1. The body of the leeches are bilaterally symmetrical like other Annelids. The body organs are also segmented.

3. Leeches either exhibit a protusible pharynx or proboscis which allows them to suck the blood of the host such features are also common in other Annelids.
Explanation:
The geologic time scale is a method of historical dating that analyzes geological strata in time. Also, the geologic time scale is the calendar for happenings in Earth history. Geologists, paleontologists, and other Earth scientists use it to explain the timing and connections of events in geologic history. Furthermore, eons are the division of the geologic time scale into influential parts of time. Eras are the smaller pieces that eons are likely to divide into, and each era is divided into periods.
