A dog whistle can be heard by dogs but not by humans. this whistle takes advantage of a characteristic of sensory systems known as:_______
Answer:the absolute threshold
Explanation:
A dog whistle can be heard by dogs but not by humans. This sound of whistle takes the advantage of a characteristic of sensory systems which is known as absolute threshold.
What is Sensory system?A dog whistle is a type of whistle which emits the sound in the ultrasonic sound range. Humans cannot hear the range of ultrasonic sound but some of the other animals can, such as dogs and domestic cats, and this ability of animals is used in their training.
An absolute threshold is the least amount of stimulation which is needed for a person to detect the stimulus 50% of the time. This ability can be applied to all the senses such as: The minimum intensity of light we can see. Similarly, the ultrasonic range of sound is not audible to humans.

What factors might favor the evolution of semelparity versus iteroparity in different species of salmon?
What factors might favor the evolution of semelparity versus iteroparity in different species of salmon?
A number of factors such as changes in water temperature, size at reproduction, energy loss during reproduction, and post reproductive feeding may significantly affect post reproductive mortality (Baird et al., 1986, 1987.
What is semelparity versus iteroparity?Living things have two different reproductive options: semelparity and iteroparity. A species is categorized as iteroparous if it experiences several reproductive cycles throughout its existence, and semelparous if it exhibits just one reproductive event before passing away
In truly semelparous species, death following reproduction is a component of a larger plan that includes optimizing reproduction at the expense of future existence. There will always be some iteroparous individuals who pass away between their first and second reproductive episodes, but this is not considered semelparity unless it is a symptom of a syndrome of programmed death after reproduction. Semelparity and iteroparity are extremes along a spectrum of potential methods rather than opposing ones strictly speaking.

Is the indicator stain in this microscope slide localized in organelles or distributed evenly throughout the cell?
The indicator stain in this microscope slide will be localized in organelles.
What are indicators?Substances called indicators are those whose solutions change color as the pH changes. We refer to these as acid-base indicators. The conjugate base or acid versions of these typically weak acids or bases have various hues because of variations in their absorption spectra.Organic weak acids or bases with complex structures are indicators. To assess the pH (acidity or basicity) of a solution visually, a little amount of a halochromic chemical substance is added to the solution.Therefore, under the Arrhenius model, a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+). According to the pH, the indicator typically causes the color of the solution to change. Other physical attributes can also alter, as seen by indicators.To learn more about pH indicator with the given link

What is glycolysis?Glycolysis is a cytoplasmic mechanism that converts glucose into two molecules with three carbons each and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose. This reaction uses adenosine triphosphate (ATP), and the end result, glucose-6-P, inhibits hexokinase.What happens during glycolysis?The process by which glucose is broken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. Importance of glycolysis:Because it is the metabolic process by which glucose produces cellular energy, glycolysis is significant.

The amount of tension produced in a skeletal muscle as a whole structure is determined by which mechanism?
The amount of tension produced in a skeletal muscle as a whole structure is determined by the frequency of stimulation and the number of muscle cells stimulated.
The sarcomeres in the muscular fibers of the skeletal muscle must shorten in order to move an object, referred to as a load. Muscle tension is the force produced when a muscle contract (or when sarcomeres shorten).
Back pain episodes can result from muscle tension, which is often brought on by the physiological effects of stress. By narrowing blood vessels and decreasing blood flow to the body's soft tissues, such as the muscles, tendons, and nerves in the back, stress may alter the neural system of the body.
More myofibers contract and there is more tension in the skeletal muscle when more motor neurons are triggered.

Most lipids are nonpolar. This property causes lipids to be water-insoluble in the bloodstream. Lipoproteins form water-soluble complexes for transport through the bloodstream by surrounding nonpolar lipids with polar phospholipids and proteins .
A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.

Which testicular cells help deliver sperm to the epididymis by contracting rhythmically?
Myoid cells help deliver sperm to the epididymis by contracting rhythmically.
All mammalian species have peritubular myoid cells that surround the seminiferous tubules in the testis, but each species has a different arrangement of these cells inside the peritubular interstitial tissue. They are actin-containing contractile cells that play a major role in spermatozoa transport via tubules. By helping to lay down the basement membrane, they give the tubules structural rigidity.
The function of Sertoli cells has also been found to be impacted by this, and PTM cells and Sertoli cells can communicate with one another via secreting growth factors and elements of the extracellular matrix. PTM cells are essential for establishing proper spermatogenesis, according to studies.Overall, PTM cells play a part in regulating spermatogenesis through cellular contact and preserving the tubules' structural integrity.
