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>.
Answer:
The correct answer would be <u><em>Garden plants grow better in wet soil than in dry soil.
</em></u>
Scientific hypothesis refers to a proposed or tentative explanation for the occurrence of a particular phenomenon.
Testable hypothesis are those which can be approved or denied on the basis of results of any testing, experience, or data collection.
From the given choices, only fourth hypothesis can be scientifically or experimentally tested.
Same types of plants can be grow in dry and wet soils keeping all other variables constant (such as temperature, light, nutrients et cetera) in order to check the effects of the soil on the plant growth.

E transformation in creating bacteria genetically engineered to produce human proteins.
Small, single-celled organisms called bacteria exist. Nearly all areas of the world are home to bacteria, which are essential to their ecosystems. Some species can survive in environments with high pressure and temperatures. The average person's body is teeming with bacteria, and it's thought that bacterial cells outnumber human cells. The bacteria that hurt us are the bad ones.
They are known as pathogens. These might be picked up from our surroundings. Vibrio cholera, the bacteria that causes cholera, can be obtained through consuming food or water that has been tainted with an infected person's feces, as well as by coming into direct touch with an infected person.
