The nasal cavity is the hollow pipe (your nostril and upwards) that is covered with hairs and muscus membrane. Its main functions are to warm, moisturise, and filter air before it entering the body.
Hope it help :)

Answer:
I would say that the answer is A. So Sorry if I'm wrong, but I'm 99% sure.
Explanation:
From left to right.
1) Cytokinesis is almost
finishesd, so it’s the end of Telophase
2) The chromatids have just
split up and are migrating to each pole, so it’s Anaphase
3) All chromosomes are in the
equatorial plane, so it’s the end of Metaphase
4) The chromosomes are in the
poles and cytokinesis has just started, so it’s the beginning of Telophase
5) The spindle apparatus is
complete and the chromosomes are moving to the equatorial plate, so it’s the
beginning of Metaphase
6) The spindle apparatus is forming,
so it’s Prophase
If you want to put them in
chronological order, it’s like this:
6-5-3-2-4-1
Answer:
It is able to produce oxygen
Explanation:
The line of evidence that would support my claim is that the observed prokaryotes can produce oxygen. The cyanobacteria or the blue green algae are the only know prokaryotes that utilises photosynthesis which leads to the release of oxygen. Since it has already been established the discovered organisms is a prokaryote, it can then be confirmed that since this organism can produce oxygen, it is a cyanobacteria and that it also has features peculiar to the cyanobacteria
Answer:
At low Ts= Hopanoids increase membrane fluidity
At higher Ts= Hopanoids reduce the membrane fluidity
Explanation:
Bacterial membranes lack cholesterol but have hopanoids. Hopanoids are synthesized from the same precursor as the steroid. The hopanoids also have five fused ring structures like that of cholesterol. The amphipathic nature of hopanoids allows them to maintain the membrane fluidity under low and higher temperature conditions.
When the temperatures are higher, the hopanoids serve to reduce the membrane fluidity by their ability to interact with polar heads and non-polar tails of the membrane phospholipids. At lower temperatures, hopanoids insert themselves between the non-polar tails of phospholipids to increase the membrane fluidity.
