The primary function of a plasma membrane is to protect the cell from its surrounding. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to icons and organic molecules and regulates the movement of substances in and out of cells. Meaning the answer should be “the bilayer structure forms a solid boundary that separates a cell from its environment.”

What is the best way to get information concerning an athlete's psychological strengths and weaknesses

Marrrta [24]

Answer:

oral interview and psychological inventories

Explanation:

Through degree training, psychology professionals are acquiring a set of tools, techniques, procedures and methods, from different theoretical schools, which are used to evaluate and intervene with the people they work with. Some call these people "patients", but in the field of sport, it is preferable to speak of "athletes" or simply "individuals", since the word patient, from the biomedical paradigm, refers to "passivity", to someone who suffers pain and expects the professional to "take it away." The individual with whom the sports psychologist works (the athlete or the team, the coach, the referee or any other “actor” in the field of sport) could say, is a worker, that is, that is not waiting for solutions provided by the psychologist, but works helped by him to improve his psychological skills for training and competition, without neglecting his health and personal well-being.

The objective of this work is to present the psychological interview as a tool widely used by professionals who work in this field, but little studied, in relation to its objectives, how to carry it out and its scope.

If the vibrations have a low frequency, the sound is heard as a _______. If the vibrations have a high frequency, then the sound

spin [16.1K]

If the vibrations have a low frequency, the sound is heard as a __low-pitched sound_____. If the vibrations have a high frequency, then the sound is heard as a __high-pitched sound_____.

Explanation:

High pitched sound is of higher frequency because they make the air molecules vibrate much faster than low-pitched sound. Due to their high frequency, their wavelength is shorter (Remember wavelength and frequency are inversely proportional). Vice versa is true to the low-pitched sound. They vibrate air molecules slower than high-pitched sound. Their wavelength is longer and frequency smaller.
