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.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
