Where in the DNA molecule does hydrogen bonding occur?

Describe the two categories used to classify physical changes

Fed [463]

The two categories that are used to classify physical changes are Reversible and Irreversible.
Reversible means that the matter can convert to gas, liquid and solid and then convert back to gas, liquid or solid. So it means it can convert back and forth. Irreversible means that matter cannot be converted back as it is before.

Answer:

Theory of Plate tectonics: states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere

Lithosphere: the rigid outer part of the earth, consisting of the crust and upper mantle.

Convection currents: occur when a heated fluid expands, becoming less dense, and rises

Seafloor spreading: the formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid-ocean ridges and its subsequent outward movement on either side.

Paleomagnetic: is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials.

Divergent boundary: occurs when two tectonic plates move away from each other.

Convergent boundary: is an area on Earth where two or more lithospheric plates collide.

Rift valley: A rift valley is a linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault.

Transform fault boundary: A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.

Subduction zone: is a region of the Earth's crust where tectonic plates meet.

Trench: Trenches are long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another.

Continental-oceanic convergence: When two plates come towards each other they create a convergent plate boundary. The plates can meet where both have oceanic crust or both have continental crust, or they can meet where one has oceanic and one has continental.

Continental-continental convergence: So when two continental plates collide, they just smash together. When two plates of continental crust collide, the material pushes upward. This forms a high mountain range. The remnants of subducted oceanic crust remain beneath the continental convergence zone.

SMC (structural maintenance of chromosomes) proteins are associated with chromatin in many types of organisms. Two of the major

umka21 [38]

Answer: 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
