Answer:

The members of each group of living things share a set of special features unique to that group. Scientists are always looking for these characteristics or 'observable features' which allow them to group different species together and see how they are related to each other.

Well all animals are known for their characteristics so are placed in specific groups that match with their characteristics. Hope this helped :)

Answer:

• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.

{ \rm{HA _{(aq)} \:  \:  {}^{ \dashrightarrow} _{ \dashleftarrow} \:  \:  H {}^{ + } _{(aq)} +A {}^{ - }  _{(aq)}}} \\

• pH level of an acid;

  1. Strong acid → 0 - 3.8
  2. Weak Acid → 4.0 - 6.7

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution
Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

<u>The cell contains a </u><u>more concentrated solution</u><u> than the solution in the container</u>. The difference in concentration would produce an <em>osmotic gradient</em> that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

Explain the purposes of gene expression studies. Describe the use of DNA microarray assays and explain how they facilitate such
denis-greek [22]

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
