The most important property of the cell membrane<span> is its selective permeability: </span>some substances<span> can </span>pass through<span> it freely, but others cannot. Small and nonpolar (hydrophobic) molecules can freely </span>pass through<span> the </span>membrane<span>, but charged ions and large molecules such as proteins and sugars are barred passage. </span>

Selective permanently, is the reason why the cell membrane only let's certain things pass through. small noon polar molecules (oxygen & carbon dioxide) pass through by simply diffusing. But other molecules use other types of passive transport or active transport.

Which is useful for high-throughput sequencing, but is not part of sanger dna sequencing?
Shalnov [3]

Roche/454 pyrosequencing , useful for high throughput sequencing techniques. This method utilizes pyrosequncing which allows for sequencing as the sequence read out can be achieved at the same time as the sequence is extended.

High- throughput screening is the use of automated equipment to rapidly test thousand to millions of samples for the biological activities at the model organism, cellular, pathway or molecular level.Many DNA samples can be sequenced simultaneously.

Sanger DNA sequencing also known as chain termination. This method is used only for the single DNA fragment at a time. Amplicon sequencing with  NGS is efficient and cost effective . It is required a DNA  polymerase , nucleotide , dideoxynucleotides and buffer.

what sources of information are considered reliable according to the strict standards of scientific investigation?
garik1379 [7]

Answer:

Peer-reviewed

Explanation:

If  a scientific report is peer-reviewed it means that the contents of the report are corroborated by other scientists hence the veracity of the information is high and is very reliable. The best scientific reports clearly describe the experiments that were conducted to culminate to a particular scientific conclusion. The experiment is able to be replicated by another scientist and if the same results are achieved then the results are corroborated and the report positively reviewed.

What is the composition of the asthenosphere?
BartSMP [9]

The asthenosphere lies 80-200km below the surface under the lithosphere. Convection also occurs in the asthenosphere. The asthenosphere is mostly made of up rock material (magnesium and iron silicates). The asthenosphere makes up 6% of the mantle and lets the lithosphere move.

Best of Luck!

many organisms that undergo chemosynthesis use instead of to fuel the processes that convert carbon dioxide into sugars.
OLEGan [10]

Answer:

Many organisms that undergo chemosynthesis use hydrogen sulphide (H2S) instead of sunlight to fuel the processes that convert carbon dioxide into sugars.

Explanation:

Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulphide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis. Example, bacteria and methanogenic archaea living in deep sea vents
