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 secon
Alik [6]

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.

a. The fetus undergoes the most rapid weight gain during the first trimester.

b. The fetus takes an average of 30 weeks to mature after conception.

c. Fetal organ systems develop at a steady rate throughout pregnancy.

d. To ensure proper growth, a fertilized egg must implant in the wall of the uterus.

Answer:

The answer is letter d, To ensure proper growth, a fertilized egg must implant in the wall of the uterus.

Explanation:

The fetal development process starts with the conception and implantation. <em>Conception</em><u> is the process by which the male's sperm meets with the woman's egg cell in order to be fertilize</u>d. Once the egg is fertilized, it has to be implanted in the woman's uterus. Once it adheres to the wall, the fertilized egg cell (embryo) now becomes known as a<em> "blastocyst."</em> This is a very essential stage for fetal development because this allows the embryo to receive proper nutrients from its mother.

Implantation occurs at least 6 to 9 days after the egg is fertilized. A woman may experience the following symptoms:<em> fatigue, breast tenderness, increased urination, food cravings, morning sickness, mood swings, headaches, etc.</em>
