When DNA was discovered, Watson and Crick saw that the strands of the double helix are lined up in the opposite direction of each other. This type of orientation is called the antiparallel orientation.
The antiparallel orientation is a type of orientation showing two polymers present side by side but running in the opposite direction. The best example of this is the deoxyribo nucleic acid (DNA). DNA molecule is made up of a pair of polynucleotide strands which are antiparallel. The antiparallel orientation of the DNA facilitates the hydrogen bonding between the two complimentary strands. This is also important for the processes of DNA replication and transcription.
Answer:
Cushing's syndrome
Explanation:
Prolonged hypersecretion of glucocorticoid hormones by the adrenal gland causes a hormonal imbalance where the person begins to accumulate fat and lose bone and muscle mass.
Remember, one of the most important glucocorticoid hormone is cortisol, also known as the stress hormone, it usually helps us respond to conditions that are difficult for our body and where we need to use our strength and mental dexterity, when this hormone is elevate, we can respond to stress situations more easily. It helps us activate all the metabolism, as a result, we need to use more energy.
If cortisol remains elevated all day, despite not making physical and mental strength, our body will think it needs to eat, so people with this syndrome are always hungry, and accumulate fat. Thus leading to the appearance of the symptoms of the syndrome.

Hey my friend did this one on Answer.com
<span>
Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.</span>
Answer:
The sea floor magnetic field is layered in stripes of alternating north and south polarities. That tells us the polarity of the Earth while that particular stripe was being formed. This is how the ocean floor keeps track of the magnetic field.
