Answer:
The dura mater and pleural contain fluid which lubricates the brain and lungs respectively.
Explanation:
Dura mater is the outermost layer and a sac in the brain that envelope arachinoid and it's surrond venous channels which carried blood from the brain to the heart. The dura mater contain cerebrospinal fluid and drains it from the brain to the internal jugular vein
The pleural help in the proper functioning of the lungs and it supply pleural fluid which lubricates the lungs and allow for respiration.
Answer:
Option D, Number of limbs
Explanation:
Options for the question
a. Birth weight
b. Hair color
c. Number of offspring
d. Number of limbs
Solution
Variation within a species is caused due to genetic differences governed by varying allele frequencies and duet to environmental factors that somewhere effect the expression of the genetic potentials thereby causing phenotypic variation.
Number of limbs is a physical characteristics, very unlikely governed by genetic variation. While factors such as hair color (grey, black, white etc.), height (tall, short, medium) etc. are governed by genetic variation as a result of which they have several phenotypic variations.
Hence, option D is correct
Strike Slip
A fault in which surfaces on opposite sides of the fault plane have moved horizontally and parallel to the strike of the fault.
Answer:
In codominance, two dominant genes express itself in appearance (phenotype). For example, In people with AB blood types, A and B are both dominant genes and both try to show themselves in blood type, which forms third blood type AB.
In incomplete dominance, the organisms with heterozygous genotype (Aa) will have a blended trait instead of showing dominant trait because dominant gene (A) cannot show itself necessarily in appearance (phenotype). For example, when a plant with homozygous red flower (dominant and AA) is crossed with white flower (recessive- aa), the resulting offspring will all have heterozygous flowers (Aa) and pink (blended), instead of showing dominant trait (red).
