Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.
It seems that you have missed the necessary options for this question, but anyway here is the answer. Glaucoma has been one of the leading causes of blindness and a common form has been linked to three genes and more that 20 genetic loci. So the statement that best describes glaucoma is that, <span>a polygenic trait that is influenced by the number of alleles present. Hope this answer helps.</span>
Answer:
Transferred to a different chromosome without a reciprocal exchange of genetic material
Explanation:
Translocation is one of the structural abnormalities of chromosomes. During translocation, a segment from the chromosome breaks off and attaches to the non-homologous chromosome. Translocation can be reciprocal or nonreciprocal.
In reciprocal translocation, the exchange of chromosomal segments occurs between two non-homologous chromosomes. On the other hand, the nonreciprocal translocation, one chromosome loses its segment to a non-homologous chromosome but does not get the same from the recipient chromosome.
