D it allows all substances to enter & exit the cell.
Answer:
What would be the expected result of the experiment?
For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.
But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.
How would you interpret the results if the scientist observes no new volcanic activity?
I would say that does NOT invalidate the theory because the observation period is extremely short. 10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all. Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.
Where are the many similarities..?
Answer: melanin
Explanation: Further, other cells contribute to the function of the epidermis. Melanocytes are cells that produce melanin, a compound involved in skin pigmentation produced in response to ultraviolet (UV) light exposure (6). Melanin can absorb energy from UV light to shield underlying tissues from damage.
Answer:
The main structural component of plant cell walls is cellulose which is a type of carbohydrate made up of a long chain of glucose molecules (a polysaccharide).
Explanation:
The plant cell walls are composed of cellulose, which is a structural carbohydrate made up of a long chain of glucose molecules (β linked D-glucose units). It is a polysaccharide like starch, but the starch molecule is flexible and the cellulose molecule is rigid. Each of these polysaccharide chains is connected together by hydrogen bonds. Microfibrils are formed by arranging some of these polysaccharide chains in parallel arrays. Due to the presence of hydrogen bonds, the microfibrils are extremely tough and inflexible. This property of cellulose provides strength and rigidity to the plant cell walls.
