Answer:
The beetles gland stores enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. Thus pulsed mechanism is beneficial for the beetle survival because the system uses pressure instead of muscles to eject the spray at a constant velocity, saving the beetle energy.
Samples of the mineral pyroxene normally exhibit HARDNESS OF 5 TO 6.
Pyroxenes are a group of rock forming minerals, which are found in both igneous and metamorphic rocks. The mineral is composed of many elements including: sodium, iron, magnesium, calcium, manganese, zinc, lithium and other smaller ions. They are also usually found in volcanic lava.
Answer:Plants are cloned to produce identical plants quickly and economically. Producing new plants by cloning is quicker than allowing plants to reproduce then collecting and sowing seeds. It's therefore an effective way of producing new individuals from rare and endangered plants, helping to preserve the species.
Explanation:
they might add a disease-resistance gene from one plant
