20 chromosomes because unfertilised eggs contains half the number of bodily chromosomes
<span>Unused
embryo in the in-vitro-fertilization can be kept frozen until a certain period
of time until couple can decide if they will use it again to try for another
baby. Many couple are having a difficult time of thinking of what to do in
their unused embryo. Some might donate it to infertile couples rather than
thawing it without donating. Letting the unused embryo go is not abortion
because it does not have a life yet, but in abortion the baby is alive in the
womb and the mother tries to remove the baby intentionally. </span>
Answer:
That isn't true
Explanation:
That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.
Hop this Helps!
