Explanation:

Conception officially occurs during fertilization.During ovulation, a mature egg is pushed through the fallopian tube and is available for fertilization.During implantation, a fertilized egg travels into the uterus.A zygote is created when an egg and a sperm join during fertilization.

A sperm cell and an egg cell join together to form a zygote, the process of fertilization is called Conception. When a mature egg is produced during ovulation and comes into contact with a sperm cell, fertilization usually occurs in the fallopian tube.

The resulting fertilized egg, known as a zygote, continues to undergo cell division after fertilization and moves down the fallopian tube toward the uterus. Normally, this journey takes several days.

The zygote is implanted as soon as it enters the uterus. The process by which the fertilized egg adheres to the lining of the uterus is known as implantation.

In the context of human reproduction and the creation of a new life, it is important to understand the stages of conception.

One-fourth of adults in the United States are not active at all. Please select the best answer from the choices provided.

Answers

Answer: this is True on edge

Explanation:

Answer:

The correct answer is true.

It is true that one-fourth of adults in the United States are not active at all.

It is not something to celebrate, but this number of American citizens are adults that do not practice any sport or do regular light exercise to take care of their body and maintain good health. This type of sedentary life is very risky because sedentary people are prone to cardiovascular diseases. And if they have overweight, the situation is more complicated.

Explanation:

In the following scenario, who is being abusive?

Troy and Megan often argue about the importance of school. Troy says Megan spends too much time studying. She needs to have more fun because she is only young once.

Alana and Mike have been dating. Alana tells Mike she does not want to see him any more.

Ellen does not like Ted to spend time with his friends. He would spend his evening with her if he really loved her.

Renee and Shane are in English and American Government together. They take the opposite side on just about everything—politics, religion, and even the meanings of poems.

Troy
Ellen
Renee
Alana

Answers

Answer:

Ellen

Explanation:

Ellen is using a manipulative tactic to make Ted feel bad about spending time with his friends. Saying that "if he really loved her" makes him think that if he spends time with his friends, it's saying he doesn't love her. In doing this, Ellen is manipulating Ted into doing what she wants.

Answer:

C but its a poor choice.

Explanation:

I think 3 is the abusive one, but not very. Ellen is very needy, and that's the real problem.

Troy is just making an observation. He's not demanding anything and he's certainly not being abusive in his observation. He'd just like to see her have more fun.

Alana is being truthful. That's not abuse even though it is very painful for Mike.

Renee and Shane have a very good honest relationship. They disgree but they have a healthy disclosure policy. Neither really wants to hur the other.

Please *NO SPAM* a) _____ makes our bones and teeth strong. b) Proteins are called _____ nutrients. c) ______ helps in making blood. d) Oil and butter are good sources of ______. e) People who do a lot of physical work need more ______.

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, there are some general terms that should indicate the answer. This question also seem to focus on the classes of food and food in general, thus the answers should be related to food.

(a) Calcium is mineral needed in the body to make bones and teeth stronger.

(b) There are two broad types of nutrients; they are micronutrients and macronutrients. Micronutrents are those nutrients that the body needs in little amount/quantity (examples are vitamins and minerals) while macronutrients are nutrients that the body requires in large quantity (examples are carbohydrates, proteins, and lipids)

(c) Iron is a mineral that assists in blood production in the body.

(d) Oil and butter are good sources of lipids in the body.

(e) More water/glucose is required for people who do a lot of physical work. Water helps transport nutrients around the body which helps to produce energy (that is needed after an exercise); an individual exercising loses water through sweat and will need to gain this water back by drinking. While glucose break-down leads to the production of energy. This is the reason water or glucose is needed more by an individual who do a lot more physical work.

Assignment Directions:
Create your own personal training log.

Assignment Guidelines:
A personal training log is a record of your physical activity. It should be created in a table (Microsoft Word) or spreadsheet (Excel) format. The log should contain enough information so that you know what dates you exercised on, what activity(s) you did, how long you spent exercising, and any weights used (if applicable). It should also contain a spot to note personal fitness improvements made with each exercise session.
The final requirement is to set a fitness goal for yourself. What do you want to accomplish by being physically active? Some examples include losing weight, gaining muscle strength, improving cardiovascular conditioning or getting ready for a competition. These are just examples though. Your goal can be anything you want to achieve in relation to your physical health. Write your goal above your log.
You will first submit this log blank for review by your teacher by uploading it as an attachment (do not use the answer box). At the end of the course in the lesson entitled "Racewalking", you will be submitting your completed log to determine how well you have done with achieving your fitness goals.
