Answer:
amplitude, wavelength, frequency, and speed.
Explanation: Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
Because they dont want to kill the grass or the plants that they want. but only to kill the plants its meant for
C is the most suitable answer
Answer:
D) None of the above
Explanation:
Arthropods are characterized by the possession of an exoskeleton and a segmented body. This group includes insects, arachnids, myriapods (centipedes and millipeds), and crustaceans.
The Devonian period, belonging to the Paleozoic Era, occurred from around 415 million to 350 million years ago. During this era, arthropods such as centipedes, millipedes, and flightless insects were predominant and diversified throughout this period.
Therefore, as all of these arthropods were present in the Devonian period, the correct answer is <u>d) None of the above</u>.
Answer:
b.the recipe because it can be passed on to all relatives
Explanation:
A crooked nose is a genetic trait and can be passed to the progeny via genes only. Sexually reproducing organisms such as humans experience segregation of traits during gamete formation. Therefore, crooked nose inheritance is a chance factor regulated by the inheritance of genes and the segregation of alleles. On the other hand, a recipe for chocolate chip cookies can be shared with all the relatives and other individuals of the population by any means without any conditions. Therefore, a recipe will spread more quickly through the population.
