The three ways mutations can occur are
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.

DNA is a long polymer of nucleotides (long strand of A,T,G,C in a defined sequences for any given gene.

The three types of mutations are 1. Substitution where a base is changed from its original to a new base (A—>G) 2 insertion where a nucleotide is added into the DNA. 3 Deletion where a nucleotide is deleted.

1 substitution 2. Insertion 3 deletion

Mary bought three flowering plants for her garden. The first one has red tubular flowers filled with nectar; the second one has
uranmaximum [27]
I would say that the first flower attracts birds etc. t go and drink it's nectar (also I know that humming birds are attracted to red), and thus spread it's pollen. The second flower most likely attracts bees seeing how t is also sweetly scented, but has no nectar. This must mean that it only has pollen, which bees are great at spreading! I have no clue about the last one....Maybe bugs or bats?? Those are the only other pollinators I know of. It could possibly be that there is no pollinator for the third flower and it just tries to keep animals and insects from eating it with it's shape and odor and just relays on the wind for pollination.<span />

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hea
Ronch [10]

Answer:

Diffraction

Explanation:

Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.

Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

hope this helps :)
