What is Oparin's Hypothesis?
In 1924, Aleksandr Oparin (and John Haldane separately in 1929) hypothesized that the formation of amino acids and proteins from non-living chemicals, a process known as "abiogenesis", could have occurred in the conditions present shortly after the formation of the Earth. This process would not be observable now because other organisms would absorb created proteins, which would be rare anyway due to the higher concentration of oxygen in Earth's current atmosphere. Oparin's Hypothesis (also called the Oparin-Haldane Hypothesis) remains unconfirmed as a possible source for life on Earth. Experiments that simulated past conditions on the Earth did generate some simple amino acids, but not in the form or complexity of organic proteins.
What kind current is produced by a dry cell?
A dry cell battery does not use current it produces a current when connected to an electrical load. The type of current that the dry cell produces is DC (direct current).
What is the tallness trait of a pea plant moving separately from the color trait an example of?
This is an example of Mendel's second law, the Law of Independent Assortment, which states that the appearance of one trait will not affect the appearance of another. Current understanding of genetic inheritance, however, has shown that this is not always the case because two genes which are located close to each other on the same chromosome will most likely be inherited together.
What is the maximum current in zinc carbon dry cell?
Maximum Current draw - 20 (milliamperes)
Who discovered conjoined twins?
The "first" conjoined, or siamiese twins were Chang and Eng Bunker, from Siam (current Thailand). They were born in 1811, and are said to be first, altough there are two other earlier cases. The earliest are so-called "Biddenen Maids", Mary and Eliza Chulkhurst, born in England in 1100. They were said to be conjoined from the hip, but sometimes also from the shoulders. Of course, there are earlier cases, but these are the first to have known names.
What are synonyms of hypothesis?
Another word for 'hypothesis' is an educated guess, which is essentially what a hypothesis is. It is a guess taked from what you assume will happen, given your current knowlege.
Which type of current involves charge flow in single direction?
A direct current involves change of flow in a single direction.
What is a science answer to a science question?
Usually the current 'answer' to a scientific problem would be called a theory. However when used in an experiment people refer to the current answer to a problem as the nul hypothesis and the new, to be tested, theory as the alternative hypothesis.

Is Congress likely to extend the current exemptions on inheritance tax before they expire?
Congress didnt extend the current exemptions on inheritance tax. The exemptions are only temporary though and tax is likely to be reinstated fully within a year. More than likely Congress will extend the exemptions on the inheritance tax. When they are close to expiring they will be brough up for a vote.
