Red blood cells are for oxygen transport and contain a pigment called hemoglobin.

*this pigment consists of four highly folded chains with a group containing iron at the of each chain.

*the iron combines with oxygen.

*hemoglobin thus accepts oxygen in the and releases it in the .

*carbon monoxide also attaches to hemoglobin and then easily let go.

each hemoglobin can transport molecules of oxygen.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
