Answer:

Water molecules attract each other due to polarity. Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.

Water dissolves everything because it is the “universal solvent." Water has the ability to dissolve many substances but the term “universal solvent" is misleading. Water is able to dissolve other polar molecules and ions, such as sugars and salts.

Which of the following is a species?

maks197457 [2]

Answer:

e. All of the above are considered species under at least one species concept.

Explanation:

All of the abovementioned conditions satisfy at least one condition of species definition. Further arguments are given below to support each statement,

a. A species is the monophyletic group of individuals who has a common ancestor which could be distinguished from the closest phylogenetic relative based on conserved genes (16S in bacteria and 18S in eukaryotes). In the statement above, beetles satisfy this condition.

b. A species is the group of individuals that are capable of exchanging genes or can interbreed. In the above statement, birds who are interbreeding with each other must be a single species.

c. A metapopulation is generically defined as the group of populations who are separated by space but are the same species according to phylogenetic analysis. Thus, the metapopulation of salamanders who are linked by gene flow (gene migration) should be treated as one species.

d. The word "lineage" already conveys the message that these bacteria belong share sample place in the phylogenetic tree and they are capable to adapt the same environmental niche. Therefore, they should be considered as one species. This can be easily tested via 16S rRNA sequencing.

True or False. If you have one concussion you are more likely to get a second one.

After having one concussion you are more likely to have another — some doctorsestimate you increase your risk up to three times. There are two reasons why your risk increases: carelessness and brain chemistry.

Answer:

No, it is not a scientific theory.

Explanation:

A scientific theory is a proposition that is made to explain the various phenomena that are occurring in nature and it is supported by experiments that have repeatability and well-analyzed results.

Scientific theories are usually tested in experiments under controlled conditions and verified as well.

In the given situation, the theory made by the observer is not being tested through any experimentation or quantification and therefore, it is just a hypothesis and not a scientific theory.
