Cholesterols are amphiphatic molecules. This property allow cholesterol to insert themselves into cell membranes by interacting with phospholipids which are also amphiphatic in nature. A molecule is said to be ampiphatic if it has both polar and non polar regions.
Answer: Prepare to deliver the baby on-scene.
Explanation:
Birth crowning is a condition occurs during the period of gestation. In this baby's head starts emerging after each contraction from the birth canal after the second stage of labor. In this process the uterine muscle relaxes and tightens to help the newborn to come out of the birth canal.
According to the given condition, a preparation of delivery of the baby on the scene is preferred to avoid the negligence and delay. To protect the life of mother and child early action is required.
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another lower in the food chain, the energy is transferred by heat and movement, some though is lost. They eat each other but it only gets half the energy stored. A food web is similar - it is just a series of food chains.
Answer:
Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.
Explanation:
As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.
The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.
A diagnosis is the name or identification of a problem according to ones symptoms
