Organic matter in soil is also called _____.
loam
talus
humus
regolith
Answer:
The correct answer would be humus.
Humus is the organic material of the soil formed by the decomposition of the dead plants and animals. It is thick and dark in color (brown or black) and can also be produced by the process of composting.
It is very for the soil as it adds moisture to the soil, enhances the structure of the soil which increases the aeration and drainage.
It favors the growth of organisms (such as earthworm) helpful for the growth of plants and adds lots of nutrients to the soil, specially nitrogen.
In contrast, loam is a type of soil which is composed of silt, sand, and clay in 40-40-20 ratio. Regolith referred to the superficial layer covering the solid rocks or bedrock. It is formed by the accumulation of soil, dust, broken rocks etc on the bedrock.
Lastly, talus referred to the slope which is formed by deposition of shattered rock debris at the base of a cliff.
Two brown eyed parents have produced three blue eyed sons if they have another child what are the chances that it will also have blue eyes
A) blue eyes are dominant in this family so there is a 75 percent chance the next will be blue eyed
B) after having three blue eyed children there is a 0 percent chance of having another
C) both parents carry a recessive allele for blue eyes so there is a 25 percent chance of having another
D) since all their children are blue eyed there is a 100 % chance the next will too
Cells are largely made of organic compounds that contain carbon. Which property of the carbon atom makes it an essential component of organic compounds?
Carbon is solid at room temperature.
Carbon can form four covalent bonds.
Carbon is a nonmetal.
Carbon oxidizes to carbon dioxide.
Answer:
I think it might be B
Explanation:
If you search if Carbon can from four covalent bonds it can. And it wont matter if its a non metal and if its solid at room temperature so I think its B. Please correct me if im wrong.

A client has been prescribed timolol eye drops. what are three (3) possible adverse effects of this medication and nursing interventions/client education related to these effects?
The use of timolol eye drops involves side effects such as irregular heartbeat, vision changes, and trouble while breathing. During such visible effects, a person must not drive and inform the doctor beforehand about their medical history related to lung or heart diseases.
Further Explanation:
When high pressure is build up inside the eye as a result of glaucoma or ocular hypertension, it is being treated by a medication called timolol eye drop. It lowers the pressure and helps in the prevention of blindness. This eye drops work by reducing the fluid content of the eye, thus stabilizing the pressure. Timolol comes under the class of beta-blocker drugs.
Before using the eye drop, one must read the information leaflet carefully. The hands must be washed before applying the eye drop, and one must not touch the tip of the dropper to avoid contamination. The people who use contact lenses must remove them to apply the eye drop and wait about 15 minutes before wearing the contact lenses again.
There are certain common and adverse side effects linked to the use of this medication. The common side effects are:
Blurred vision Itching or redness in the eye Watery or dry eyes HeadacheThe adverse effects include:
Irregular or slow heartbeat Vision changes Troubled breathing Chest pain Dizziness and fainting
When the doctor prescribes the timolol, the patient must inform the doctor regarding any of the medical histories he or she might have. This is because the prescribed medication contains some inactive ingredients which might be allergic to the patient. A person with medical conditions such as lung disease, heart disease, sinus bradycardia (a type of irregular heartbeat) must inform the doctor as the serious side effects of this medication might elevate the symptoms of these diseases.

List and describe the four common passageways for non water molecules entering or exiting the cell
Final answer:
The cell membrane utilizes four main passageways for non-water molecules: passive osmosis and diffusion for gases and small molecules; transmembrane protein channels and transporters for small organic molecules; endocytosis for large molecules or cells; and exocytosis for removing or secreting substances.
Explanation:
The cell membrane controls the movement of substances into and out of the cell, utilizing different passageways for non-water molecules. These include:
Passive osmosis and diffusion: These processes allow for the transport of gases (such as O₂ and CO2) and other small molecules and ions without the requirement of energy input from the cell.
Transmembrane protein channels and transporters: Specific proteins facilitate the movement of small organic molecules, such as sugars or amino acids, across the cell membrane.
Endocytosis: This pathway enables the transportation of large molecules or even whole cells into the cell by engulfing them through the cell membrane.
Exocytosis: Conversely, exocytosis involves the removal or secretion of substances, such as hormones or enzymes, from the cell.
The cell membrane's selective permeability ensures that only specific substances can pass through, maintaining the cell's internal environment.

Those members of the population who are capable of developing a disease or condition are known as:
Answer:
The correct answer is - The population at risk.
Explanation:
The population at risk is the population that is prone or capable of developing a disease or the more likely to exposed by the presence of the event that is vital such as diseases.
The population that are at higher risk for any event that is leads to a condition that decreases or negatively affects the population.
Thus, the correct answer is - the population at risk.
