In garden pea plants, tall stem height (T) is dominant over short stem height (t), and green pod colour (G) is dominant over yellow pod colour (g).
Some Genotypes of Pea Plants TTGG TTGg TTgg TtGG TtGg Ttgg ttGG ttGg ttggWhat number would be for the following? Correct me if I am wrong, please :)
*Pea plant used for a test cross: #3 is what I put, is that right?
Heterozygous tall and green pod pea plant #4 is what I put, is that right?
Yellow pod heterozygous tall pea plant #6
Just one more double check:

A stimulus causes a change in permeability of neural membranes, which begins the process of transmitting an impulse. If the stimulus reaches the threshhold potential of a neuron, an action potential is generated. Select the numbers of the statements below that occur once the threshold potential is reached.
1. Sodium ions flow into the neuron.
2. Sodium ions flow out of the neuron.
3. The membrane potential becomes positive.
4. The membrane positive becomes negative.
5. Voltage-gated potassium channels open.
6. Voltage-gated potassium channels close.
7. Potassium ions flow into the neuron.
8. Potassium ions flow out of the neuron.
Place the numbers in order from the first event to the last event_,_,_,and_ .
