First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst.
a volcano is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
There are three main types of volcano - composite or strato,shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
Answer:
Scientist count the world humans population with an organization called The United Nations Population Division (UNPD),
Explanation:
Which keeps track of the world population, projects that the world's human population will hit 7 billion on Halloween Day 2011. Admittedly, that is just an estimate: There's no way to know exactly how many people are alive at any given moment, and the true date that humanity's ranks will surpass 7 billion could come in the weeks or months before or after Oct. 31. Nonetheless, the UN's guess is the best there is.
In the prophase of mitosis if 18 duplicated chromosomes are in a cell then the number of chromosomes in interphase is <u>9</u>.
A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
A sister chromatid is one that has two identical copies of a chromosome that are connected by a common centromere during chromosome DNA replication. In other words, a sister chromatid can also be thought of as "one-half" of a chromosome that has been duplicated. A dyad is a pair of sister chromatids.
Sister chromatids, which are firmly connected at the centromere region of each chromosome, are created as a result of DNA replication during the S phase (synthesis phase). Each chromosome is a duplicate at this point and is made up of two sister chromatids.
