Order the following steps in the q cycle. the question is graded as all or nothing, so all steps must be in the correct order for credit.1. a second qh2 molecule binds in the qp site and is oxidized. one electron ends up on a new cytochrome c, and the other goes to the bl heme.2. qh2 is released into the membrane.3. the q in the qn site is reduced by the electron from heme bn, forming a semiquinone intermediate.4. the first qh2 is oxidized at the qp site. one electron ends up on cytochrome c, and the other goes to the bl heme.5. the oxidized q molecule moves from qp to qn, stimulating electron transfer from heme bl to heme bn.6. the electron from heme bl moves to heme bh and is used to reduce the semiquinone in the qn site.7. the q molecule is released into the membrane.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.

Iwill mark brainliest and all that sha-bang. what is the function of the endocrine system? a. control longer term response in the body. b. transmit messages throughout the body. c. remove waste from the body. d. all of the above
