The correct answer is B. The iris would get smaller, the pupil would get bigger.
Explanation
The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.
Prokaryotes do not have a nucleus, rather the DNA floats freely in the cytoplasm. Also, prokaryotes are much smaller than eukaryotes, and are typically bacteria or eubacteria.
Eukaryotic cells have membrane-bound organelles and nucleus, and are larger than prokaryotes. Some examples of eukaryotes are plant and animal cells. Hope this helps! :)
“A network of microfilaments, intermediate filament, and microtubules.”
Answer:
With the phosphodiester backbone and with the bases via the minor groove
Explanation:
Nucleosomes form hydrogen bonds with the DNA to allow for the compacting of the DNA in eukaryotic cells. The nuceosomes consists of histone octamer surrounded by several base pairs wrapped in an helical manner.
The DNA interacts with the nucleosomes via it's histone octamer; the minor groove of that DNA bonds with the base pairs of that nucleosomes mostly the A:T base pairs more than the G:U; the phosphodiester backbone of the DNA.
