How are the roots adapted for taking in water and nutrients?
Roots have a big surface area and thin walls, which allow water to pass into them easily and the roots are very long they go down and down under the soil to find water.

Why can a single celled organism like a paramecium survive outside the body while a human cell would die?
A paramecium is more comparable to a whole human body than a single human cell. It contains the entire digestive stsyem (which for a paramecium, is simply taking in food, taking out nutrients and expelling waste). For a human cell, it is completely reliant on the respitory, digestive, and circulatory system. In order, one is used to obtain and get rid of gases, one is used to break down food, and the last is used to deliver both to the cells. Many singly cell or simple multi-cellular cells can, if needed, absorb gases through osmosis as they are so small, there waste is easily removed, food does not need to be transported and digestion is simple. Therefore, the paramecium does not have to deal with all the complexities the human cells must to survive.
Which two body systems are mainly responsible for taking in nutrients food molecules and getting rid of waste products?

What is the system that is responsible on taking in oxygen and taking of carbon dioxide?
respiratory
What are the Four main functions of the circulatory system?
The main functions of the circulatory system in the human body are the delivering of food to the cells, delivering of oxygen from the lungs to the rest of the body, the taking of Carbon Dioxide from the cells and taking it to the lungs and the transportation of blood proteins and hormones to the different organs and systems.
What body system are related to taking in nutrients and expelling them from the body?
digestive and excretory
What is the system responsible for taking in oxygen and removing carbon dioxide from the body?
The respiratory system is responsible for taking in oxygen through the lungs and exchanging it with carbon dioxide, which is then exhaled out of the body. This system includes the nose, airways, lungs, and muscles involved in breathing.
Which part of a plant takes in water and nutrients from the soil?
The roots of a plant are responsible for taking in water and nutrients from the soil. They have root hairs that increase the surface area for absorption.
What plant structure does a plant use to obtain water?
Plants use their roots to absorb water from the soil. The root system of a plant is responsible for taking up water and nutrients from the ground to support the plant's growth and functions.
Where in the digestive system is the absorption of nutrients taking place?
Mainly in the small intestine. A small amount of absoprtion of nutrients can also take place in the stomach and large intestine.
Room services duties and responsibilities?
Delivering the food and taking order .
How does the circulatory system circulate nutrients?
Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
What does a mitrocondria do?
Mitochondria is the powerhouse of the cell. They act like a digestive system, taking in nutrients, breaking them down, and creating energy rich molecules for the cell.
What is taking in nutrients through the small vein?
TPN, or total parenteral nutrition, is taking in nutrients through a small vein. It is used when a patient can't tolerate nutrition via the digestive system.
