Bacteria exposed to DNA can incorporate the DNA and change phenotype.
Hope this helps.
Have a nice day.
Duchenne muyscular dystrophy is caused by a mutation on the X chromosome, so a male gets it from his mother's X, if she is a carrier. The male child gets a Y and no X from his father, so the disease is always transmitted through the X from the mother. If a female gets Duchenne muscular dystrophy she has to have two X chromosomes, one from a carrier mother and another from from an affected father. This is virtually impossible because most males die before childbearing age and there is no way a female child can get an X from a man who does not live long enough to procreate. About eight percent of carrier women do show some muscle weakness, but they do not have the disease.
Answer: They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
The temperature and salinity has a major impact on water current of oceanic water. The warm water is usually less denser than colder water, so it remains at the surface of water body, whereas the colder water being more in density remain in a depth. The salinity of cold water is more than the warm water.
According to the above explanation, they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them is the correct explanation.
It wants you to explain why its a chemical change. Signs of chemical changes are formation of gas bubbles, cloudyness, change in color or odor.
Answer:
Sphingolipids
Explanation:
They are derived from aliphatic amino alcohol sphingosine and functions in protecting the nerves in the central nervous system. Sphingolipids includes group of lipids called glycolipids and sphingomyelin. Just like phospholipids they have polar heads and two non-polar tails together with proteins, forms a myelin sheath. They insulate the nerves and causes quick transmission of electrical impulse amongst organs contributing to normal bodily functions.
