Select the correct partial path below. this is path is part of the complete blood flow pathway. you should be able to trace flow starting in any location.-systemic veins returning to the left atrium and forward through the mitral valve-aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the triscupid valve-pulmonary trunk to pulmonary arteries to pulmonary capillaries to pulmonary veins returning to the right atrium-pulmonary artery into left atrium through mitral valve to left ventricle

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.  

hope its .

c should be the answer

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
