Answer: The female is a carrier for hemophila, since the parents are phenotypically normal and The Turners syndrome is caused by an error which caused the missing chromosome to dissapear duting oogenesis (egg prodiction) or spermatogenesis (sperm production)
Explanation:
Hemophila is an X-linked recessive disease an in this case has complete penetrance ie. The phenotype will be expressed.
Here the parents do not express hemophilia thus indicating that the mother (this is an X-like recessive disease) expressess hemophila on the recessive X chromosome
Turners Syndrome is caused by chromosomal non-disjunction during oogenesis or spermatogenesis.
Lichens are widely used as environmental indicators or bio-indicators. If air is very badly polluted with sulphur dioxide there may be no lichens present, just green algae may be found. Therefore the answer is the air quality is good because of no lichens present
Answer:
The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
Explanation:
-------------------------------------Passive Transport---------------------------------------------------
In passive transport, substances move across the cell membrane without the use of cellular energy. This process just happens naturally. It is important to remember, as mentioned before, that substances move naturally from a higher concentration to a lower one. Think of a crowded room. In these cases, the moment that the door opens and people are allowed to leave the crowded room for more space, they do so. Passive transport acts in the same way.
