5'-AUGUGGCAU-3'. The codon table may be used to identify the probable mRNA nucleotide sequences encoding for the tripeptide Met-Trp-His.

We can see from the table that the amino acid this has two possible codons, whereas Met and Trp each have one codon. As a result, the tripeptide might be encoded by two distinct mRNA nucleotide sequences. The template and non-template DNA strands can be produced from these prospective mRNA sequences after the nucleotide sequences for the potential mRNA have been identified.

the solution is hypotonic, (just a little salt) then water will move into the cell. a plant cell just expands until the membrane is in full contact with the cell wall.

Hypotonic solutions have low solute concentrations in them. Hypotonic in terms of the cell is a solution with 0.5% salt. A cell experiences a net inflow of water when it is placed in a hypotonic environment. As a result, the cell expands. When kept in a hypotonic environment, cells absorb water from the surrounding medium and swell. Plant cells have a cell membrane that exerts pressure against the cell wall, which in turn applies pressure to the swelling cell but prevents it from bursting. Rigid cell walls contain plant cells. Osmosis occurs when it is submerged in a hypotonic solution, or a solution with a lower solute concentration than the cell. Plasmolysis, a process, causes a cell placed in a hypertonic solution to shrivel and die.This will result in an increase in cell turgor pressure.

Dehydration or physiological stress can cause an increase in osmolarity above 300 mOsm/L, which in turn increases ADH secretion and water retention, causing an increase in blood pressure. ADH travels in the bloodstream to the kidneys.

vasopressin, also called antidiuretic hormone, a hormone that plays a key role in maintaining osmolality (the concentration of dissolved particles, such as salts and glucose, in the serum) and therefore in maintaining the volume of water in the extracellular fluid (the liquid space that surrounds cells). B (Hypotonic hydration. Hypotonic hydration occurs when extracellular fluid becomes so hypotonic (dilute) that water enters cells. Excess water is present in cells, intracellular compartments, and extracellular compartments.) The main factors that stimulate the production and release of aldosterone by the zona glomerulosa are angiotensin II and the serum potassium concentration. If a disturbance causes the osmolarity of the extracellular fluid to increase, water will flow out of the cell into the extracellular space to balance the osmotic gradient; however, the total body osmolarity will remain higher than normal and the cell will shrink.

Water conduction is one of the tracheid's functions. Answer (c) is the right choice.

The ability of water to conduct an electrical current is measured by its conductivity. Conductivity rises with salinity because dissolved salts and other inorganic compounds carry electrical current. At 20 °C, water has a thermal conductivity of 0.598 W/m-K. Pure water does not conduct electricity and is a great insulator. Water that contains contaminants, such as salts, can carry electricity. Salts divide into various electrically charged atoms known as ions when they are dissolved in water. Positive Na ions and negative Cl ions are the components of salts, such as sodium chloride (NaCl).

In dehydration, water is lost, and in hypovolemia both water and electrolytes are lost.

What is fluid deficiency?

Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions.

Which are types of fluid deficiency?

Deficient fluid volume (also referred to as hypovolemia or dehydration) occurs when the loss of fluid is greater than the fluid input. Common causes of deficient fluid volume are diarrhea, vomiting, excessive sweating, fever, and poor oral fluid intake.

What happens during hypovolemia?

Hypovolemic shock is an emergency condition in which severe blood or other fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working.
