The best answer/s would be <span>thick eyebrows and thin eyebrows and </span><span>curly hair and straight hair.
The other options do not correlate directly to each other, so they will most likely not come from the same gene!

<h2>Genetic variation & Heredity</h2>
Explanation:
- HEREDITY ONLY: none
, genetic variation: none
- BOTH: all fertilization
, metaphase 1→anaphase & 1 metaphase 2→anaphase 2 crossing over
- DNA replication
- In organisms that reproduce sexually, the processes of DNA replication, the precise pairing of homologs during crossing over, chromosome alignment and separation in meiosis I and II, and fertilization ensure that traits pass from one generation to the next
- Unlike with asexual reproduction, offspring of sexual reproduction are genetically different from each other and from both of their parents. Mechanisms that contribute to genetic variation include:
- Errors (mutations) that occur during DNA replication
. The production of recombinant chromosomes due to crossing over
. The independent assortment of homologous chromosomes in meiosis I
- The separation of sister chromatids (which are no longer identical due to crossing over) in meiosis II
- The random fusion of male and female gametes during fertilization
Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.
Soil can be described as the D. Loose covering of weathered rocks and decaying organic matter.
I believe A. Barnacles living on a whale's skin is an example of a particular symbiotic relationship.
