Hello. This question is incomplete. The full question is:
If Sally has a fitness goal to improve her mile run time from 10 minutes and 15 seconds per mile to below 8 minutes and 30 seconds per mile in 3 months, which training plan using the heart rate zones would best help her achieve her goal?
Sally should do all her workouts in zone 4 in order to increase her anaerobic threshold.
Sally should most of her workouts in the 5th zone to increase speed.
Sally should do most of her workouts in the 1st and 2nd zones to increase her ability to withstand fitness activity.
Sally should do most of her workouts in zone 3, but have some of her workouts
Answer:
Sally should do all her workouts in zone 4 in order to increase her anaerobic threshold.
Explanation:
The heart rate zones are used to measure the athlete's cardiovascular strength and to improve the intensity of physical training. These zones are divided into 5 phases, with phases 1, 2 and 3 geared to provoke the athlete's adaptation to training intensity and 4 and 5 geared to cause greater physical performance to workouts of greater intensity.
Sally wants to increase the intensity of her training, for this reason, we can conclude that she must do all her exercises in zone 4. This is because this zone has the ability to increase the body's aerobic threshold, promoting increased resistance and speed of the body , which will allow Sally to finish her training in less time.
Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.
Answer:
f. Lipoproteins can be distinguished by their densities and composition.
Explanation: Lipoproteins are special particles made up of droplets of fats surrounded by a single layer of phospholipid molecules. Phospholipids are molecules of fats which are attached to a phosphorus-containing group. They are distinctive in being amphipathic, which means they have both polar and non-polar ends.
Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function.
