Their difference lies in the prefix used before each root word, atom. The diatomic molecules are composed only of 2 atoms such as that of the diatomic elements: H2, O2, N2, Cl2, etc. On the other hand, polyatomic molecules are made up of three or mole atoms such as NH4+, H2SO4, etc.
Answer:
1.566 x 10^2
Move the decimal to where the number being multiplied by 10^x is greater than 1 but less than 10. Then multiply it by 10^x
X is the number of times you moved the decimal, so in this case it would be 10^2
Answer:
Transverse wave and Longitudinal wave and Electromagnetic wave
Explanation:
- An inverted wave is a wave in which the vibrations of the particles are perpendicular to the direction of wave motion.
- Longitudinal waves, on the other hand, are waves in which the vibrations of the particles are parallel to the direction of wave motion.
- Electromagnetic waves are waves that do not require medium media for transmission, including radio waves, microwaves, UV lights, etc.
- Most electromagnetic waves are transverse in nature.
For a flower to be pollinated, pollen from an anther (which is located at the top of the stamen) needs to reach a stigma (at the top of the pistle.) Some plants are genetically capable of pollinating themselves if their own pollen reaches their own stigma; some plants are not capable of self pollination under any circumstances.
For plants that can genetically self pollinate, but would prefer not to, they can avoid this by having their pistil and pollen/stamens mature at different times. If the stamens mature first, the pollen will be dispersed by animals or wind or whatever dispersal mechanism it relies on. Then by the time the pistil is ready to be pollinated, there is no pollen left in that flower to land on the stigma.
