Question

6. Define the following terms:-
a. Breathing rate
b. holozoic nutrition
C. minerals acid
D. velocity
e. transpiration
​

Answer 1

1.Breathing rate:A person's respiratory rateis the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.

2.Holozoic nutrition:Holozoic nutrition is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of gaseous, liquids or solid food particles.Ingestion: In animals, this is merely taking food in through the mouth.

3.Minerals acid:A mineral acid or inorganic acid is any acidderived from an inorganic compound that dissociates to produce hydrogen ions (H+) in water. Mineral acids are highly soluble in water but tend to be insoluble in organic solvents. The inorganic acids are corrosive.

4.Velocity:The time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval T counted from some fixed time t0. For example, the mean velocity of the u component is. The time average of any other quantity can be defined in this manner.

5.Transpiration:Transpiration is the evaporation of water from plants. Most of the water absorbed by the roots of a plant—as much as 99.5 percent—is not used for growth or metabolism; it is excess water, and it leaves the plant through transpiration.

Answer 2

Answer:

a.The respiratory rate is the rate at which breathing occurs. This is usually measured in breaths per minute and is set and controlled by the respiratory centre.

b.Holozoic nutrition is a type of heterotrophic nutrition that is characterized by the internalization and internal processing of gaseous, liquids or solid food particles.

c.Commonly used mineral acids are sulfuric acid, hydrochloric acid and nitric acid (they are also known as bench acids). Mineral acids range from superacids (perchloric acid) to very weak (boric acid). Mineral acids tend to be very soluble in water and insoluble in organic solvents.

d.The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

e.Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
