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.

Answer:
vascular plants have a top and bottom ,a trunk and branches ,leaves or needles the bottom is a system of roots. Xylem and phloem make up transportation system of vascular plants. Xylem is made of vessels that are connected end to end to move water around.
Open and closed circulatory systems are found in animals. blood vessels transport all guilds into a cavity. when the animal moves the blood inside the cavity moves around the body in all directions. most invertebrates like crabs, insects, snails etc...have an open circulatory system.

Answer/Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
