Nexin
This is the elastic protein among tubulin doublets that link them together for ciliary and flagellae structures.
Cilia and flagella are cellular structures that facilitate movement of the cell from one area to another.
This protein also inhibits movement on microtubules from axonemes.
B. Gradualism
"Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in the slow and consistent process of change in the whole population."
Answer: spring and summer
Explanation:
If these were the choices:
A. modeling an ocean ecosystem with a saltwater aquarium
<span>B. observing the behavior of male caribou on the arctic tundra </span>
<span>C. using dissection to study the general structure of lily flowers </span>
<span>D. growing algae in different environments found on a spacecraft
</span>
Then, my answer would be C. USING DISSECTION TO STUDY THE GENERAL STRUCTURE OF LILY FLOWERS.
Other choices are very hard to do. Maintaining a salt-water aquarium is very hard while going to an arctic tundra or space is impractical.
The hips ball and socket joint is much larger than the shoulders. its also protected by more muscle.
