Look below for answers.

Explanation:

It's been a while since I've done biology, but here are my answers based on my past knowledge and a little research:

1. Chewing your food helps jump-start the digestive process because you are physically breaking down your food while also stimulating your mouth to create saliva which will begin to chemically break down food.

2. The excretory system's primary function is to excrete waste (urea, uric acid, carbon dioxide) from the body.

3. Nutrients extracted by the digestive system are distributed through out the body for a multitude of functions. Some provide growth energy for muscles or other structures, while others, like ions, provide more specific functions like signal transmition.

4. The resperatory system's primary function is to help provide an exchange of gases that are essential to cell respiration and other bodily functions.

5. They are linked through a couple of different features; both work together to provide oxygen and nutrients to cells, and both work together to create homeostasis.

6. The purpose of the Skeletal system is to provides structure for our body, assists with movement, provides protection for our important organs, makes blood cells, and also stores and releases mierals and fat.

7. The muscular system purpose is to provide movement, but it also provides stability for our joints, maintains posture, and gives us heat.

8. The function of the nervous system is to be the body's control and center for communication between the bodies limbs and functions.

Hope this helps!

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student, including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as edutech.
