New Mexico and Wyoming may contain rivers that eventually join the C<span>olorado River. Even though the main stem of the Colorado River does not pass through these states, The rivers in these states may act as tributary rivers to the Colorado River. To understand this, you need to understand how water moves across the surface of the Earth from a higher elevation to a lower elevation, and the concept of a river catchment. </span>
B. Cell membrane
Remember cell membrane is the structure aka “wall of the house” is the clear boundary between the cells internal and external environments:))
Hope this helps
Nucleus - spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.
Answer:
In molecules of RNA, uracil takes the place of the DNA base thymine . 4. Build: Continue building the strand of mRNA until you have used all of the RNA nucleotides. ... Every group of three bases of mRNA is called a codon .
Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
