The population of beetle will increasingly become green, with subsequent generations, until it becomes the dominant phenotype. This is because the green beetles will be able to camouflage with their environment and avoid being preyed on by the birds as compared to the black beetles. Therefore, the green beetle will have a high chance of reaching the reproductive stage and passing its genes to the next generation as compared to the black beetle.
Two atoms are held together by an ionic bond when an electron transfers from one atom to another atom to produce ions of different charges, which would attract and form a crystalline type of structure known as an ionic lattice.
Explanation:
The Law of Conservation of Mass can be stated as "mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction."
Answer:
The correct answer will be option-about 174 base pairs of DNA are wrapped around an octamer of histone proteins.
Explanation:
A nucleosome is the fundamental unit of the chromatin thread polymer of DNA which is made up of a nucleosome core. The nucleosome core is composed of histone proteins H2A, H2B, H3, and H4 arranged in two copies forming an "octamer structure of proteins".
About 174 bp of DNA wraps around this nucleosome which is connected to other nucleosomes through 160 to 240 bp linker DNA.
Thus, the selected option is the correct answer.
