Are there certain food groups that you eat very little of? Which ones are they and why do you eat a lot of foods from those food groups?

ANSWER.​

Answers

Answer:

Starch, Dairy and grain foods.

Explanation:

Much of the food i eat are snacks , like chips, which are starch and crackers which are grain depending on what kind. I also eat dairy a lot like ice cream, milk, yogurt, and cheese. I eat more of this because i prefer snacks instead of meals bu am working to get back into eating meals.

Answer:

I don't eat any dairy, but thats because I'm lactose intolerant so it's not like I can control whether I have dairy or not.

On the other hand, I tend to eat a lot of fruits and vegetables because I like them. I don't think it's a problem since they're good for you. But everything is in moderation I guess.

How are the components of a vector determined mathematically?

Answers

Answer:

In a two-dimensional coordinate system, any vector can be broken into x -component and y -component. For example, in the figure shown below, the vector →v is broken into two components, vx and vy . Let the angle between the vector and its x -component be θ .

Answer:

The components of a vector are determined using the coordinates of the initial and terminal points of the vector. The horizontal component is calculated by subtracting the x coordinate of the initial point from the x coordinate of the terminal point. The vertical component is calculated by subtracting the y coordinate of the initial point from the y coordinate of the terminal point.

Which types of birth control are the most effective?​

Answers

Answer:

The kinds of birth control that work the best to prevent pregnancy are the implant and IUDs — they're also the most convenient to use, and the most foolproof. Other birth control methods, like the pill, ring, patch, and shot, are also really good at preventing pregnancy if you use them perfectly.

Paragard is over 99% effective—more effective than any other hormone-free birth control method*—and most hormonal methods. In fact, the American College of Obstetricians and Gynecologists (ACOG) recommends Paragard as one of the most reliable ways of preventing pregnancy.
