The all or nothing law of action potentials mainly talks about how the axons in the neurons only fire when there is enough action potential to fire. If there is not enough action potential, then the neuron will not be able to send signals because the action potential does not fire because of the deficit.
Answer:
the F1 generation
Explanation:
If two strains of true-breeding plants that have different alleles for a certain character are crossed, their progeny are called the F1 generation
Answer:
frequency of the blue (B) allele 
frequency of the red (R) allele 
The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
Explanation:
Frequency of blue allele is
Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

Frequency of other allele

Chi Square test
See the attached file
The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
A divide is the elevated boundary between areas that are drained by different rivers system
Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
