A is 100% right. Maybe B also could be right but not sure about it cos it should be genes
Answer:
The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.
First of all you have to make both sides of the equation equal
KClO3 -------- KCL + O2
this is the way i would do it first
K - 1 K - 1
Cl - 1 Cl - 1
O - 3 O-2 From this we can see that the oxygen of both don't equal
So than from this we would need to find the common factor of the oxygen which is 6. So we would multiply 3 by 2 to get 6 as well as 2 by 3 to get 6.
The equation will now look like
K - 1 K - 1
Cl - 1 Cl - 1
O - 3 (2) = 6 O - 2 (3) = 6
so the final answere:
KCl2O3 --------- KCl + 3O2
Answer:
False
