In ASEXUAL reproduction how much of the parent's DNA is shared with the offspring?
Most is from mom, with a little from dad.
Half came from each parent.
All the DNA is the same, it's an exact copy.
In SEXUAL reproduction how much of the parent's DNA is shared with the offspring?
Most is from mom, with a little from dad.
Half came from each parent.
All the DNA is the same, it's an exact copy.
Why are insects so important to plant reproduction?
They eat nectar and do nothing else.
They move pollen from one plant to another.
They move ovules from one plant to another.

Cell Theory says: 1) All living things are made of one or more cells, 2) The cell is the most basic unit of life, AND...
3) All cells come from thin air
3) All cells come from the stork
3) All cells come from other cells
A gummy bear placed in pure water will GROW because there is a higher water concentration outside the gummy bear. Since water always goes from HIGH to LOW water concentration, the gummy bear fills up with water as the bear has a low water concentration.
True
False
WHY do most multicellular organisms reproduce sexually?
They have many cells, so they can create specialized sex cells.
They have one cell, so they can make it split in half and then mix DNA.
They have no cells, so they do not exist or care about reproducing.
WHY do most Unicellular organisms reproduce sexually?
They have many cells, so they can create specialized sex cells.
They have one cell, so they can only make an exact copy of themselves.
They have no cells, so they do not exist or care about reproducing.
