Answers

Dynamic stretching is a strategy used to improve mobility while moving through a range-of- motion, often in a manner that looks like the activity or sport that is going to be performed. Static stretching is holding a stretch without movement, usually only at the end-range of a muscle.

Answer:

Dynamic stretching involves movement, of more than one muscle group. so Static stretching isolattes one muscle group at a time and holds a position rather than moving through a range of motion. Thank me later! :)

Teenagers should get more sleep to perform
better in school and to be healthier _
(200 word essay​)

Answers

Answer:

Sleep helps to fuel your brain and your body. Teens need more sleep because their bodies and minds are growing quickly. Scientific research shows that many teens do not get enough sleep. To be at your best, you need between 8 and 10 hours of sleep every day.

Explanation:

sleep is necessary for good health, and can reduce the likelihood of risky behaviors in both teens and adults. 9 hours of sleep is the magic number for teens. It's difficult for students to hit this mark during the school year, so it could be a good idea to let your teen catch up on sleep this summer.

Although getting enough sleep may not seem that big a deal, teens who don’t get enough sleep and are overtired are more likely to struggle in school have trouble with memory, concentration and motivation the desire to accomplish a goal  be involved in car crashes and other accidents. Sleepiness the feeling of wanting or needing to sleep in places and at times when you shouldn’t affects reaction times, or  feel depressed, which can become a serious medical condition.

Sleep plays a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety. The way you feel while you're awake depends in part on what happens while you're sleeping.

Just like eating, sleep is necessary for survival. Sleep gives your body a rest and allows it to prepare for the next day. It's like giving your body a mini-vacation. Sleep also gives your brain a chance to sort things out.

EDIT AND REVISE IT IN YOUR OWN WORDS !!!!

Both the National Sleep Foundation and the American Academy of Sleep Medicine agree that teens need between 8 and 10 hours of sleep per night. Getting this recommended amount of sleep can help teens maintain their physical health, emotional well-being, and school performance. Teens are at an important stage of their growth and development. Because of this, they need more sleep than adults. The average teen needs about nine hours of sleep each night to feel alert and well rested. How much sleep someone needs depends on their age. The American Academy of Sleep Medicine has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours. Sleep helps to fuel your brain and your body. Teens need more sleep because their bodies and minds are growing quickly. Scientific research shows that many teens do not get enough sleep. To be at your best, you need between 8 and 10 hours of sleep every day.

Answers

You meet people with a simular interest.

Social interaction refers to the way people communicate and interact with each other. In team activities, social interaction plays an important role in building positive relationships among team members.

Give an example of the above ?

One example of a positive consequence of social interaction in team activities is the ability to meet people who have a common interest and goal. When team members share a common interest, they are more likely to be invested in the team's success and work together towards achieving their goals.

This can lead to stronger teamwork, increased motivation, and a greater sense of community within the team.In contrast, negative social interaction can have detrimental effects on the team's dynamics and performance. Making enemies with rivals and meeting negative people can create tension and conflict within the team, which can lead to decreased morale and productivity.

The propensity of movement of sperm decides whether it is allowed to enter into the fallopian tube.

What do you mean by Sperm?

Sperm may be defined as a male reproductive structure that consists of an acrosome, a haploid nucleus, and a tail for movement.

When the sperm is ejaculated into the vagina of the female, it passes through the cervical region to reach the fallopian tube where the process of fertilization occurs in the ampulla.

The motility, strength, and certain characteristics decide whether a sperm reaches to the region of the fallopian tube.

Therefore, the propensity of movement of sperm decides whether it is allowed to enter into the fallopian tube.
