Answer:
Hiccups are caused by involuntary contractions of your diaphragm — the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
Answer:
True.
Explanation:
The current comprise of electrons which moves in the circuit in only one direction. In a series circuit, there is only a single path for the flow of current and so the electrons flow through the wire and each of the bulbs which are present in this path before they return to the battery which connected on the other end of the circuit. The current which is received after the flow of current through the circuit has low number of electron due to usage by the bulb and resistance of wire.
Answer:
The correct answer would be B) theory: hypothesis.
A hypothesis refers to the proposed or tentative explanation of any physical or natural process.
It usually provides the first step of any research or experiment.
It is highly testable as it is tested with the help of a number of scientific experiments and observations et cetera.
In contrast, a scientific theory is a well-proven explanation of aspects of the natural world. It is based on facts which have been confirmed through experiments and observation.
If a patient experience a flu-like symptoms and characterized by myalgia and fatigue, then the patient has an Influenza A-H1N1. Influenza A have caused the world in great tragic when it first appear in Spain causing a lot of people suffer. Transmission of this virus is just like a seasonal flu, through cough, phlegm, and tiny droplets of saliva.
