Explanation:
The other options have nothing to do with the water apart from transporting it.
Answer:
The correct answer is:
Cardio exercise (B)
Explanation:
The frequency, intensity, time and type (FITT) model is a model is planning exercises that incorporate the four elements to be considered when choosing a personal goal and fitness level. Cardiovascular exercises mainly involves aerobic exercises that are aimed at strengthening the heart and lungs and making the working muscles more efficient at the use of oxygen. They also increase stroke volume (volume of blood pumped per minute) and resting heart rate. The following are what the model entails and how they fit best with cardio exercises:
- Frequency: This has to do with how often exercises will be done. Depending on the goal cardio exercises are normally recommended as moderate exercises for five or more days a week, and intense cardio for three days a week
- Intensity: This has to do with how hard you work during exercises. For cardio exercises, the heart rate monitor, perceived exertion and talk test are done to measure the intensity of the exercise
- Time: This has to do with how long each exercise session will last. For cardio exercises, the recommendation is 30 to 60 minutes for each session.
- Type: This is the actual activity that is chosen during the sessions, and it is chosen to avoid overuse injuries or weight loss plateus. The type of actvities for cardio includes exercises that are aimed at increasing the heart rate, like running, walking, cycling dancing etc.

74. (A) The height and horizontal width of the water’s path will increase.
The reason is that the position which the gardener holds the nozzle would probably increase the pressure to push the flow rate of the water along the length of the hose to push against gravity.
15. (B) From the tail of the first vector to the top of the last vector.
The direction of a vector is from its tail to its head. Examples that are similar would be an arrow or a line segment.
Answer:
Towards left
Explanation:
Applying Fleming Right hand rule in which the middle finger denotes downward magnetic field. Thumb pointing towards you is the direction of motion of electron beam.The direction of force on the electron indicated by the index finger is towards left. Hence the electron beam is deflected towards left.
