Explanation:
1. the similarity between biosphere and ecosystem is that they both have organisms that depend on each other and the difference is that biosphere uses every single organism while ecosystem only uses organisms that are inside of the ecosystem. 2. the similarity between theory and hypotheses is that they are both something that have to be scientifically proven and the difference is a theory relies on evidence and a hypothesis relies on a possibility. 3. a similarity between independent variable and constant is that they both change at the same time and the difference is that an independent variable is controlled or changed by the scientist while a controlled variable is one that they want to remain the same.
Answer: Hydrogen bonds are created between the base pairs in DNA. Adenine pairs with thymine and cytosine pairs with guanine. Adenine and thymine create 2 hydrogen bonds while cytosine and guanine create 3. These bonds are fairly weak so that they can be broken when DNA is replicated (by an enzyme called helicase which unwinds DNA). However despite them being weak they do stabilize DNA's double helix structure as well.
The system of scientific naming or nomenclature is use to identify an organisms worldwide. The system of naming of an organism is introduced by Carolus Linnaeus. The scientific name of any organism is written by its genus name and species name. This is called binomial system of naming. While writing the scientific name of an organism, the name of the genus written first with a capital letter and the name of the species is written second with a small letter. When typed scientific name is in italics and when it is hand written the genus name and the species are to be underlined separately.
In the given example, the scientific name of orange-barred sulfur butterfly is <em>Phoebis philea</em>. <em>Phoebis</em> is its genus name and <em>philea</em> is the species name.
Nephrons are the filtering structures of the kidneys. The
kidneys contain millions and millions of these tiny filtering structures that
are responsible for cleaning the blood. Nephrons are responsible for removing
excess water, wastes, and other substances in the blood that are not needed by
the body. They also return necessary substances (e.g. sodium, potassium,
phosphorus) whenever the body runs low in supply.
If these nephrons are damaged, blood will not be properly
filtered. As a result, the kidney will have different diseases and this might
lead to kidney and multiple organ failure.
