The answer is C. If you want a good experiment on this place an egg in a glass of vinegar for 6 hours, remove and place into corn syrup for 6 hours, and finally remove and place into water for 6 hours. you’ll get a really good example of osmosis in different stages.

Answer:

C. The transport of molecules into and out of the cell through osmosis and diffusion.

Explanation:

All cells have a structure called a plasma membrane or plasmalema, which acts as a barrier to prevent both the exit of cell content into the medium and the flow of any particle into the cell. The plasma membrane's main function is to transport molecules into and out of the cell through osmosis and diffusion in relation to the concentrations of salts and water inside and outside the cells. This characteristic therefore shows an important ability to select the structure, which can vary from 7 to 10 nm in thickness.

Masteriza [31]

The question was incomplete as the diagram was missing, however, the correct diagram is attached with the answer -

Answer:

The correct answer is - scale

Explanation:

The thermometer used to measure temperature by comparison of the object or the parameter of the temperature to measure, with a calibrated pattern that is called scale.

A Thermometer has two scales on both left and right side: degrees Celsius on the left and degrees Fahrenheit on the right.

As given in diagram label with "A'' in a circle on the left side is The degrees of the scale.

Of the answers below, what is the smallest nucleotide sequence that could code for a protein with 300 amino acids?
ololo11 [35]
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.

Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.

Answer:

Genes & DNA

Explanation:

Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.

What was Friedrich Miescher's contribution to the discovery of the genetic code? He created the first photograph of the structur
Rama09 [41]

Answer:

He extracted and observed DNA from white blood cells.

Explanation:

Friedrich Miescher, who is a Swedish Botanist, is the scientist who isolated for the first time. In 1869, Miescher isolated a chemical he called NUCLEIN, which is called Nucleic acid now.

He discovered this so called "NUCLEIN" substance from the nuclei of white blood cells. Nucleic acids are the DNA and RNA we know today, hence, Miescher's discovery was significant to the genetic code as he even agitated for the inclusion of his discovery into inheritance.
