The process that results in Ms. Milly’s wilting lettuce becoming firm is osmosis. The explanation is below.

OSMOSIS:

  • Osmosis is the process by which water molecules move from a region of high concentration to a region of low concentration via a semipermeable membrane.

  • According to this question, Ms. Milly, occasionally sprinkles water on her wilting lettuce and notices that they became firm.

  • The firmness of the lettuce is as a result of the movement of water into the leaf cells due to a process called osmosis.

This has to do with osmosis ( movement of water). The water is a hypotonic solution compared to the lettuce which cells are hypertonic. This causes the water to move in the lettuces cells causing the lettuce to have more structure because there is more turgid pressure.

kotykmax [81]

It is true that once glucose, galactose, and fructose enter the absorptive cells, they are transported to the portal vein and then to the liver.

Absorptive cells are also known as enterocytes. These cells line the lumen of the small intestine and the colon. They are meant to absorb the nutrients from the digested food inside the lumen of intestine. Apart from absorption, they also transport the nutrients across the membrane.

Portal vein is the blood vessel that transports blood from the GI tract, pancreas, gall bladder and spleen into the liver. This blood vessels belongs to the portal venous system. Its location is the upper right quadrant of the abdomen.

Assuming that the average protein in E. coli consists of a chain of 380 amino acids, calculate the maximum number of proteins th
Afina-wow [57]

Answer:

4210.5 proteins

Explanation:

(a)The amount of nucleotide pairs in the DNA molecule calculated using

=molecular weight of DNA/molecular weight of a single pair

molecular weight of DNA

= 3.1 × 10^9g/mol

molecular weight of a single pair

= 0.66 ×10^3g/mol

= (3.1 × 10^9g/mol)/(0.66 × 10^3g/mol)

= 4.7 10^6pairs

Lets, Multiply the number of pairs with the length per pair

Take, length per pair = 0.34 nm/pair

= (4.7 × 10^6pairs)(0.34 nm/pair)

= 1.6 × 10^6nm

= 1.6 mm

= (approx 2mm or 0.002 mm).

Therefore,

the DNA is

(1.6 mm)/(0.002 mm)

= 800

The DNA is 800 times times longer than the cell.

This indivates Tat DNA must be tightly coiled to fit into the cell.

(b) the amount of DNA molecule nucleotide pairs has given

= 4.7 × 10^6 nucleotide pairs,

From solution (a), there must be one-third this number of triplet codons

= (4.7 × 10^6)/3

= 1.6 × 10^6codons

If an individual protein has an average of 380 amino acids, each needs a codon,

the number of proteins that can be coded by E. coli DNA

= (1.6 × 10^6codons) × (1 amino acid/codon)

---------------------------------------------

(380 amino acids/protein)

= 4210.5 proteins

________________________

Here is the complete question

The genetic information contained in DNA consists of a linear sequence of coding units known as codons. Each codon consists of three adjacent DNA nucleotides that corresponto a single amino acid in a protien.

The E.coli DNA molecule contains 4.70 x 10^6 base pairs. Determine the number of codons that can be present.

Assuming that the average protein in E.coli consists of a chain of 400 amino acids, calculate the maximum number of protiens that can be coded by an E.coli DNA molecule
