Answer:

". Small population"

Explanation:

      The conditions to maintain the (Hardy-Weinberg) equilibrium are no mutation, no gene flow, a large population size, random mating, and no natural selection. This can be disrupted by changes from any of its five main factors. No migration, no mutations, and random mating are all a part of this equilibrium, so the answer will be a small population.

Answer:

due to the variability of the flow of protons and electrons through the ATPase

Explanation:

The total number of ATP is not known exactly and is due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport. ATP – Adenosine triphosphate, the energy currency of the cell is organic compound composed of the phosphate groups, adenine, and sugar ribose.

The term that can be used to describe all cellular respiration is Exothermic. Some cellular respiration may be aerobic, some are anaerobic but all the exothermic.

Cellular respiration may be defined as the methodology of transforming glucose into a form of energy (ATP) that is useable by cells.

Respiration that occurs in the presence of oxygen is known as aerobic cellular respiration, respiration that occurs in the absence of oxygen is known as anaerobic respiration.

Therefore, the term that can be used to describe all cellular respiration is Exothermic.

Answer:

C. ossification

Explanation:

All bones develop in the same way in a process called ossification. At about 10 weeks, bone tissue starts to form as cartilage or membrane. Then, calcium and phosphate – minerals stored in your body and replenished by the foods you eat – are added to the tissue

The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.

Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Animal Physiology

Animal physiology is the study of how animals work, and investigates the biological processes that occur for animal life to exist. These processes can be studied at various levels of organization from membranes through to organelles, cells, organs, organ systems, and to the whole animal. Animal physiology examines how biological processes function, how they operate under various environmental conditions, and how these processes are regulated and integrated. The study of animal physiology is closely linked with anatomy (i.e., the relationship of function with structure) and with the basic physical and chemical laws that constrain living as well as nonliving systems. Although all animals must function within basic physical and chemical constraints, there is a diversity of mechanisms and processes by which different animals work. A comparative approach to animal physiology highlights underlying principles, and reveals diverse solutions to various environmental challenges. It can reveal similar solutions to a common problem, or modifications of a particular physiological system to function under diverse conditions. The discipline of animal physiology is diverse and here the major areas of research and investigation are outlined.

Chemical and Mineralogical Composition of Soils

Of the chemical elements essential for plant and animal physiology, only carbon, oxygen, and hydrogen, are derived directly from air and water. Nitrogen and to some extent sulfur are derived from the air but must be present as inorganic ions in the soil before they can be utilize by plants. The other essential elements are obtained from the dissolution of minerals in the soil. Essential element bearing minerals are derived from the geologic material within which the soil is formed. An inadequate supply of any essential element limits plant growth. The most frequent limitations result from insufficient plant-available nitrogen, phosphorus, potassium, calcium, or magnesium.

Practically no nitrogen is present in soil minerals. Nitrogen enters the soil as ammonium and nitrate dissolved in rainwater or via fixation from the air by nitrogen-fixing microbes in the soil. Some nitrogen-fixing microbes in the soil are symbiotic and the nitrogen they extract from the air is incorporated into their legume plant host. Other nitrogen-fixing microbes are not symbiotic, and the nitrogen they extract from the air is incorporated into their cells. Nitrogen is also present in the organic residues of dead organisms in and on the surface layers of soil. Plants do not ingest the organic forms of nitrogen but as microbes in the soil decompose organic residues and exhaust carbon dioxide to the air inorganic forms of nitrogen are released into the soil solution and become available to growing plants, leach into the groundwater during periods of excessive rainfall, or return to the air as nitrogen gas during periods when the soil is saturated with water. Plant-available nitrogen contents in soil are transient and closely related to the nitrogen content in the organic residue and the rate at which the residue is decomposing.

Phosphorus is present in only a few minerals in the soil. Apatite, a soluble calcium phosphate mineral capable of supplying plant-available phosphorus, is the most common source of phosphorus and most abundant in soil formed in limestone. Iron and aluminum phosphate minerals are extremely insoluble and do not release phosphorus rapidly enough for rapid plant growth. Soils with high iron and aluminum contents tend to absorb phosphate applied as fertilizer and decrease its availability to plants. This is a serious problem in attempts to fertilize food crops in many soils in the tropics.

Potassium is present in mica and feldspar minerals. These minerals are rather easily decomposed in the soil environment and consequently are sparse in soils formed in siliceous materials and sediments that have been repeatedly transported and deposited on the land surface.

Calcium and magnesium are most abundant in carbonate minerals associated with limestone and some carbonate rich sandstone. Carbonate minerals are also relatively unstable when subjected to weathering and therefore most abundant in soils formed directly from limestone, some sandstone, and recently deposited sediments derived from carbonate rich rock.

Answer:

Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:

toxic exposure to environmental pollutants or certain medications

certain acute and chronic diseases

severe dehydration

kidney trauma

Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.

Usually, someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:

a reduced amount of urine

swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste

unexplained shortness of breath

excessive drowsiness or fatigue

persistent nausea

confusion

pain or pressure in your chest

seizures

coma

Symptoms of early-stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:

decreased urine output

fluid retention that leads to swelling in limbs

shortness of breath

A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:

a heart attack

heart disease

scarring of the liver or liver failure

dehydration

a severe burn

an allergic reaction

a severe infection, such as sepsis

High blood pressure and anti-inflammatory medications can also limit blood flow.

When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:

prostate (a most common type in men)

colon

cervical

bladder

Other conditions can interfere with urination and possibly lead to kidney failure, including:

kidney stones

an enlarged prostate

blood clots within your urinary tract

damage to your nerves that control your bladder

Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.

The following may cause ischemia:

severe bleeding

shock

renal blood vessel obstruction

glomerulonephritis
