The correct answer is B. After filtration, the lymph from lymph node travels to the subclavian veins, through efferent lymph vessels. The whole transport process is affected by smooth muscle contraction, changes in pressure and opening/closing of valves.
A, plant growth would decrease. Decomposers break down organic materials into nutrients and return these nutrients to the soil. The nutrients are vital to plant growth. If decomposers went extinct, then eventually plants would use up all the existing nutrients and start to die.
The value of 2pg in the given population is 0.432
<u>Explanation:</u>
Given:
C is normal
c is curly wings
So the homozygous dominant condition would be CC
Heterozygous condition would be Cc
Recessive condition would be cc
According to Hardy Weinberg principle,
p² + 2pq + q² = 1
and
p + q = 1
Here,
q² = cc = 100
q² = 100 / 1000
q = √0.1
q = 0.316
So,
p + q = 1
p + 0.316 = 1
p = 0.684
Thus, 2pq would be:

Therefore, the value of 2pg in the given population is 0.432
