<u>Answer:</u>

Direct DNA sequencing

<u>Explanation:</u>

Direct DNA sequencing is the type of genetic testing which is the most sensitive method for detecting any mutation in a specific gene.

DNA sequencing is a critical biological method that is used in laboratories to determine the accurate order of nucleotides, along the chromosomes and genomes.

With the help of this method, we are capable of investigating a number of diseases and genetic illnesses along with the detection of mutation in any gene.

Distinguish between a tenant farmer and a sharecropper. whose exposure to risk is greater and why
Maslowich
<span>These two terms are very closely related, but the basic difference occurs in how the tenant or the sharecropper pay the farm or agricultural land owner. Neither own the land they farm. The tenant farmer pays a certain amount of rent per year that is invariable whether they have a good crop or not. A sharecropper pays with a share of the crop harvested regardless of the quality or quantity of the crop. In other words, the tenant farmer pays a fixed amount for the land, the sharecropper pays a percentage of their harvested crop which can vary year to year.</span>

Aldosterone (a steroid hormone) is a small, nonpolar, hydrophobic molecule that enters a target cell by moving across the plasma
VMariaS [17]

Answer: Simple difussion

Explanation:

Aldosterone is a steroid hormone of the mineralocorticoid family, produced by the external section of the glomerular zone of the adrenal cortex in the adrenal gland. It acts in the conservation of sodium, both by secreting potassium and by increasing blood pressure.

Simple diffusion is the process by which molecules flow through a permeable membrane without any external input of molecular energy. This process, which is ultimately due to a<u> difference in molecular concentration between the two media separated by the membrane, does not require an input of energy</u> because its main driving force is the increase in the total entropy of the system. <u>In this process the displacement of the molecules is produced following the concentration gradient, the molecules cross the membrane from the medium where they are in greater concentration, towards the medium where they are in lesser concentration</u>.

The molecules that can easily pass through the cell membranes due to this phenomenon are only gases (e.g. CO2, O2), hydrophobic molecules (e.g. benzene) and small polar molecules (e.g. H2O and ethanol), This is because hydrophobic and apolar molecules are soluble in the central apolar region of the lipid bilayer, and small polar molecules are small enough that unfavorable interactions are compensated for by an increase in the entropy of the system. On the other hand, large polar molecules such as glucose, amino acids and charged molecules or ions (Hx+, Na+, Cl+ and Ca2+) interact too strongly with the aqueous environment outside the lipid bilayer, and it is therefore very unfavourable from an energy point of view to break these interactions to cross the central hydrophobic region. As a consequence, biological membranes are practically impermeable to this type of molecules, so they require other transport mechanisms.

<u>So, since aldosterone is small, nonpolar and hydrophobic molecule, it passes throught the plasma membrane easily, down a concentration gradient</u>.
