Stuck up
Maybe a girl looks at a guy and then acts stuck up because she is stuck up. She may have been looking in a negative way and not in a way that was checking him out.
Proto-oncogenes are genes whose products promote cell growth and division. They do this by encoding transcription factors that stimulate the expression of other genes, signal transduction molecules that stimulate cell division, or cell cycle regulators that move the ell through the cell cycle. Proto-oncogene products may be located in the plasma membrane, cytoplasm, or nucleus, and their activities are controlled in various ways, including regulation at the transcpritional, translational, and protein-modification levels. When cells become quiescent and cease division, they repress the expression of most proto-oncogene products. In cancer cells, one or more proto-oncogenes are altered in such a way that tier activities cannot be controlled in a normal fashion. This is sometimes due to a mutation in the proto-oncogene resulting in a protein product that acts abnormally. In other cases, proto-oncogenes may encode normal protein products, but the genes are overexpressed or cannot be transcriptionally repressed at the correct time. In these cases, the proto-oncogene product is continually in an "on" state, which may constantly stimulate the cell to divide. When a proto-oncogene is mutated or aberrantly expressed, and contributes to the development of cancer, it is known as an oncogene. Oncogenes are those that have experienced a gain-of-function alteration. As a result, only one allele of a proto-oncogene needs to be mutated or mis-expressed in order to trigger uncontrolled growth. Hence, oncogenes confer a dominant cancer phenotype.
a diode in a ckt basically acts like a switch!! it acts like a switch in on position i.e a short when forward biased and acts like a open ckt or a swich in off position when it is reversed biased!! its used inanalog circuits to generate different types of waves.........

The Intolerable Acts were not necessarily passed to increase trade, though that could have been a byproduct. The acts were passed to limit British authority on colonist trade.
The Spacebar acts as a character, even though it is not a letter in Microsoft Word it is classed as a character.
It can be, to mean although. It can also be an adverb.It acts as a conjunction in "Though he failed, he was still honored."It is also used as part of the compound conjunction "even though."
Gravity acts as though you were being pulled to the center (of the earth, in my case).
