Answer:The lengthy small intestine receives secretions from the ______pancrease______ and ______liver______, completes digestion of the nutrients in _________chyme_______, absorbs the products of digestion, and transports the remaining residues to the ________large________ intestine.
Explanation: digestion of food is necessary for absorption of nutrients. In this process food is broken down into forms that can be absorbed by the body . food is broken down by the teeth and the enzymes in saliva,when it is in the mouth. From there it moves to the stomach through the oesophagus. In the stomach, the content is further mixed with enzymes and the churning breaks down food further.From the stomach food moves to the small intestine. In the small intestine, digestive enzymes from the pancreas and liver acts on food. The small intestine is where digested food is absorbed.it has a large surface area and finger-like projection called villi to carry out the function of absorbing nutrients.
From there, undigested food us passed to the large intestine from where it is passed out through the anus
Answer:
This structure provides support and protection for plant cells = Cell Wall
This is a large, central fluid-filled structure that provides turgidity = Vacuole
A thin semipermeable barrier around the cell which regulates what enters and leaves the cell = Cell membrane
The control center of the cell = Nucleus
It is often described as the cells Power Plant = Mitochondria
This is used by plant cells for photosynthesis = Chloroplast
Hope this helps :)
Plz mark Brainliest :D
Explanation:
The giant blue thing is the vacuole
The thin yellow line is the cell membrane
The yellow and orange ball is the nucleus
The light green thing with zig zag lines is the mitochondria
The dark green thing inside the cell is the chloroplast
The thing outside the cell is the cell wall its green
