Answer:
A. maintenance of axons is not a cellular activity associated with microtubules.
Explanation:
Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
Answer:
BECAUSE THEY LIGHT DISTRACTS IT
Explanation:
Answer:
Benthic Zone- bottom of ocean
Pelagic Zone- the open ocean that is not near the coast.
Oceanic zone- Zone that is beyond the continental shelf
Neritic zone- Zone that exists over the continental shelf
Photic zone- Zone where sunlight pass through
Aphotic zone- Zone where sunlight cannot pass through
Explanation:
There two important zones of the ocean that can be termed as Benthic Zone which lies at bottom of ocean or sea and Pelagic Zone that could be imagined as a cylinder or water column that goes from the surface of the sea or ocean to its bottom. At the very bottom of the sea there lies an ecological region termed as Benthic Zone.The pelagic zone can also be termed as the open-ocean zone and it is in contrast with water that is nearer to the coast or continental shelf.
There are different zones that lies within a Pelagic Zone. They are
Oceanic, Neritic, Photic, Aphotic. The zone that lies beyond the continental shelf comes under this oceanic zone and Photic and Aphotic as the name suggests it refers to light. It referes to the zones where sunlight can penetrate and can not penetrate respectively.

Answer:</h2>
There two features which facilitates bird <u>to fly are presence of light and smooth feathers and light bones</u>.
<h2>
Explanation:</h2>
Birds are the only living creatures which has the ability to migrate from one place to another through flying. There are many physical features present in their body which facilitates them in flying.
<u>Among the two features and their role in flying are as follows: </u>
-
Light and smooth feathers: Wings are the organ which is involved in flying. It is composed of feathers which are very colorful and are light in weight and smooth in its appearance. This apart from reducing the body weight helps the bird to reduce the force and drag during flying.
- Light bones: The skeletal system of the birds is composed of light bone which are primarily hollow with air sacs. This accounts for less body weight while flying.
