Answer:
arrow (which creates the resultant vector)
Explanation:
When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn.
With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction.
Below is an example:
Let:
V1 = Vector 1
V2 = Vector 2
R - resultant vector.
The answer is pronuclei. A pronuclei is the state of the
nucleus of either the sperm or the ovum after the sperm has entered the ovum
but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane
of the sperm pronuclei dissolves hence leaving no barrier for the two genetic
materials to combine.
Answer: 70 grams.
Explanation:
The mean of the population of the tomato weighs 60gms and average weight of plant is 80gms.
Narrow sense heritability (h2) is 0.30
Average mean weight of fruit after is given as;
( narrow sense heritability) =(M2 - mean population) / (average weight- population weight)
0.30 = (M2-60) / (80-60)
0.30 (20) = M2 - 64
6 = M2 - 64
Collect like terms
M2 = 64+6 = 70g
M2 = 70 grams
