This statement about matter is true: MATTER IS MADE UP OF ATOMS AND HAS MASS. 
Matter is defined as anything that has mass and occupies space. The mass of an object is the measure of the extent to which the object can resist a change in its direction when a force is applied to it. A matter is usually made up of atoms, which is defined as the smallest component of any matter. Therefore matter is made up of atoms and it has mass.

What is the best explanation if the gel of your PCR product shows smeared bands of multiple sizes? Select one:
trapecia [35]

Answer:

e. None of the above

Explanation:

For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA  which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.  

i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.

vfiekz [6]
<span>Tertiary</span> structure - three-dimentional structure of one polypetide chain.

Proteins are considered as for their conformation in four different stages:

Primary structure is referred solely to the sequence of amino acids<span> in the polypeptide chain.
</span>Secondary structure is the immediate basic folding of a protein and it can be α-helix and β-sheets.
Tertiary structure is the three-dimentional folding of a singles polypetide.
Quaternary structure is the thee-dimenional structure that results from the combination of two or more individual polypetides working as single protein.

Which of these is correct regarding the permeability of a specific capillary type?
Vsevolod [243]
Red platelets are too vast to leave any capillaries. As capillaries are just a single cell thick and have thin porous dividers this implies substances can diffuse out of them effortlessly. Helpful substances, for example, oxygen and sustenance diffuse out of the blood in the vessels into the tissue liquid where it is then taken to the cells.
