Answer:
Beautiful Huntresses: Scientists Explain Why Mantises Evolved To Resemble Orchids : The Two-Way Typically, when insect females evolve to become larger than males, it's in order to produce more offspring. But female orchid mantises evolved to look like flowers for a sinister reason: to hunt prey.
Answer and Explanation:
The steps of the sliding filament theory are:
Muscle activation: breakdown of energy (ATP) by myosin.
Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.
Muscle contraction: cross-bridge formation
The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.
Recharging: power (pulling) stroke
The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.
Relaxaction: cross-bridge detachment
The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.
The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.
Answer:
a gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect caused by increased levels of pollutants.

Answer:
Explanation:
Fish decreased algal biomass and directly increased all biogeochemical rates. The relative importance of the different abiotic ecosystem properties varied by process; however, FBOM and substrata size were important for most rates.
Conjugation - this is when bacteria exchange genes among each other. Sexual reproduction is when genes from the male and female are fused to create a new diverse zygote. Bacteria can do a similar process by conjugation.<span />
