Match the following: 1 . muscle fiber sends message from brain to move up 2 . erythrocyte keeps tissues involved alive, provides oxygen for energy for motion 3 . neuron keeps the tissues involved free of disease 4 . leukocyte causes the actual contraction of muscles to raise leg

1. Muscle fiber: causes the actual contraction of muscle to raise legs

2.Erythrocyte: keeps tissue involve alive, provides oxygen for energy for motion

3. Neuron: sends message from brain to move up

4. Leukocyte: keeps the tissue involved free of disease.

Explanation:

1. Muscle fiber: causes the actual contraction of muscle to raise legs.

The muscular fiber is a long elliptic cell, able to contract, extend, stretch and respond to electrical changes in the membrane.  

2. Erythrocyte: keeps tissue involve alive, provides oxygen for energy for motion

An Erythrocyte or red blood cell contain a protein called hemoglobin, which transport oxygen ions from the lungs towards the whole body.

3. Neuron: sends message from brain to move up.

A Neuron is a specialized cell from the nervous system that receives, processes and transmits information from the brain to other parts of the body.

4. Leukocyte: keeps the tissue involved free of disease.

A Leukocyte is a type of blood cell that belongs to the immune system. They fight infections and other diseases.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
