RNA primers required for polymerase to continue synthesis must be present on both leading and lagging strands during DNA synthesis.
RNA Primer is RNA that initiates DNA synthesis. These primers are required for DNA synthesis because DNA polymerase is unable to initiate polynucleotide. Polymerase require a template and RNA primer to synthesize DNA in the 5 prime to 3 prime direction (5'-3'). One RNA primer is only required on the leading strand, because DNA is produced continuously on leading strand. Whereas DNA is synthesize in small lengths on the lagging strand, therefore more than one RNA Primer is required on lagging strand.

Ronald Myers and Roger Sperry transected both the optic chiasm and corpus callosum in a group of research cats, and then put a patch on one eye. this had the effect of a split brain.
Because there are two routes for visual information to pass from one eye to the contralateral hemisphere, Myers and Sperry excised the corpus callosum and the optic chiasm from each cat in their main experimental group.
The folded cerebral cortex is a component of the gray matter of the brain. The grooves between the folds create fissures. The longitudinal fissure is the greatest fissure in the cerebral cortex that separates the brain's two hemispheres. The corpus callosum is made up of white matter. The corpus callosum acts as a natural connection between the two hemispheres of the brain. Roger Sperry excised a portion of the corpus callosum while researching ways to treat epilepsy. The LVF, which is controlled by the right side of the brain, only transmits visual information to the right hemisphere, whereas RVF only transmits visual information to the left. There are two writing implements required. Try to sketch both of the images at once, one on each piece of paper, as soon as you see them. the body's left side. The actions of your right body are controlled by your left brain. The left and right visual fields of each eye are separate regions; this illustrates the impact of a split brain.

suppose the extracellular fluid (ecf) osmolality becomes too high. what hormone would most likely be released to correct this situation?
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.

By changing the structure of their substrates to resemble that of the transition state, enzymes help speed up processes. The lock-and-key paradigm, in which the substrate perfectly fits into the active site, is the most basic explanation of how an enzyme interacts with a substrate.
However, substrate binding frequently modifies the configurations of both the enzyme and substrate, a process known as induced fit. In these situations, the substrate's conformation is changed to more closely approximate that of the transition state.

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.
