Answer:
Ia tidak mempunyai badan fizikal.
Penjelasan:
Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.
Answer:
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
Answer:
<em>The correct option is A) Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as the movement of molecules against a concentration gradient i.e from an area of lower concentration to an area of higher concentration.
Facilitated diffusion can be described as the movement of molecules guided by other molecules such as integral proteins. These kinds of movements are a type of passive transport as the molecules move along the concentration gradient from an area of higher concentration to an area of lower concentration.
