Water requires the addition of 2260 Joules of heat energy for every gram of water that evaporates (vaporizes). The heat energy that is required to change water into vapor is called the latent heat of vaporization.</span>
Answer:
ATP is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. ATP then provides the energy to pull the myosin back, by hydrolysing to ADP + Pi.
Shale >>> Slate >>> Phyllite >>> Schist >>> Gneiss
Answer:
Observers ahead of the wave observe an apparent increase in wave frequency
Explanation:
This is the Doppler Effect. The frequency of a wave increases when the source approaches the observer and decreases as the source recedes.
B, C, and D are wrong. Observers behind the source notice a decrease in frequency.
Answer:
located... on the plasma membrane
is considered... inactive
the messenger is considered... to be active
All of this is brought on by a.... signal molecule
will shut down quickly when the.... signal molecule
Explanation:
The G protein-coupled receptors (GPCRs) are transmembrane proteins found on the plasma membrane. GPCRs are considered to be the most diverse group of transmembrane receptors in eukaryotic cells. These proteins (GPCRs) bind to signaling molecules to trigger signaling pathways through Guanine nucleotide-binding proteins (G-proteins). G proteins are signaling proteins (for example, Ras protein) that bind both GTP and GDP. After the signaling molecule binds to GPCR, GTP is hydrolyzed by the G-protein in a process that triggers specific signaling pathways (for example, activation of the production of second messengers).
