<p>dci, was that E?</p>
<p>yeah it was E</p>
<p>yup put that too</p>
<p>What did you guys get for the very first question with the frog vs snake breathing thing?</p>
<p>Only one answer choice had to do with respiration ^</p>
<p>I put number 1 as skin</p>
<p>I put skin.</p>
<p>i put fossils for the frog vs snake thing and for respiration it was like it humidifies air while it reaches trachea or something i am not sure</p>
<p>what did you guys get for the ancestor question between reptiles and birds? and the one with respiration question</p>
<p>For E-
-clams dont have radial symmetry.
-Larva vs embryo? I said different niches
- evolution of birds and reptiles?
- energy flowing through ecosystem?
-England moths- aa/black would increase
-1,000,000</p>
<p>the difference between the oxygen and the atmosphere is that it is moistened. and for the fossils, it was e, the reptile fossils had scaly skin and feathers</p>
<p>yeah clams are mollusks so they dont have radial symmetry</p>
<p>The place where plants’ branches grow is the apical meristem, right? And also, the xylem is nonliving, correct?</p>
<p>hmmm i dont know if it was different niches. i put different niches first but then i was thinking it mite have something to do with the amount of offspring produced. the rest of are rite @medicalboy.</p>
<p>@satman
you are right</p>
<p>i put cambium for where they grow because thats where the division occurs. next, i put epidermis for nonliving, because the epidermis is not alive in plants or humans.</p>
<p>the cambium is for lateral growth… like annual rings and stuff</p>
<p>xylem is nonliving they are composed of dead cells</p>
<p>How does energy travel through an eco system?</p>
<p>through only one direction from bottom to high</p>
