The cilia serve to transport dust and other foreign particles, trapped inmucous, to the back of the nasal cavity and to the pharynx. There the mucus iseither coughed out, or swallowed and digested by powerful stomach acids. After passing through the nasal cavity, the air flows down the pharynx to thelarynx.
Answer:
Based on knowledge of enzymes and the given data, it can be concluded that Tcn-protease is most likely active in the alligator's stomach and Wx-protease is most likely active in the alligator's intestines. As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.
Explanation:
- A pH less than seven is acidic
- A pH of at or around seven is neutral
- A pH of more than seven is alkaline (basic)
Answer:
Give at least 3 reasons why viruses are considered non-living and therefore NOT classified into the Linnaean system of life.
Viruses as we know that they are micro-organism but they are not produced from cell
Viruses does not grow rather undergo replication by multiplying into several number within minutes
also they rely on host energy as they could not produce energy needed for their usage.
Explanation:
Every living organism are made up of cells which makes it the fundamental unit of life where virus does not fall into such category, Growth is an essential characteristics of every living organisms, viruses only replicate rather they does not undergo growth.

Explanation:
1. The nuclear lamina is a network inside the nucleus which maintain the shape of nucleus.
2. It is composed of intermediate filaments and many proteins.
3. It providing mechanical support to the nucleus and play many other rolls in the cell.
4. In a cell if the nuclear lamina fall into disarray, the nucleus is misshapen and all these processes run awry. Such cells in which nuclear lamina is broken, they tend to become senescent in response to internal dysfunction, and cause damage to surrounding tissue.
