Smc (structural maintenance of chromosomes) proteins are associated with chromatin in many types of organisms. two of the major complexes that eukaryotes possess are cohesins and condensins.
sort the following phrases as describing cohesins, condensins, or both. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.

1) generally dimeric, forming a v-shaped complex
2) hold sister chromatids together after replication, until chromatid separation
3) each terminus contains part of a site for atp hydrolysis
4) contain two coiled-coil motifs connected by a hinge domain
5) associated with kleisin
6) essential for dna replication and cell division
7) contributes to the compaction of chromosomes during mitosis and enables proper chromatid separation during anaphase

Since the sentences are already descriptive enough, here are the proper names according to the abilities condensins and cohesins have or not:

1) generally dimeric, forming a V-shaped complex : condensin

2) hold sister chromatids together after replication, until chromatid separation : cohesin

3) each terminus contains part of a site for ATP hydrolysis : both

4) contain two coiled-coil motifs connected by a hinge domain : both

5) associated with kleisin : condensin

6) essential for DNA replication and cell division : both

7) contributes to the compaction of chromosomes during mitosis and enables proper chromatid separation during anaphase: cohesin

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
