What is the purpose of the mucus in your nose?
Options- A. Protects lungs
- B. Clear air passage
- C. Protects nose
- D. All of the above
- Correct Answer
- Protects lungs
ExplanationWhen you breathe in air through your nose, it contains lots of tiny things, like dust, dirt, germs, and pollen.
The air enters our body through the nose. However, before it enters the lungs, it must be heated and purified. Many dust particles that enter along with the air are removed in the nose by mucus and thus it protects lungs.

Correct Answer: a legislature consisting of a lower and an upper chamber
Correct Answer: Earth's gravitational pull
Correct Answer: Diwansingh
Explanation:
Correct Answer: xylem and phloem occur on the different radii
Explanation:
In angiosperms the vascular bundles are mainly of three types (i) radial (ii) conjoint (iii) concentric.
(i) Radial : Presence of radial vascular bundles is the characteristic feature of roots. Those vascular bundles in which xylem and phloem are present on different radii are known as radial vascular bundles. In between xylem and phloem bundles parenchymatous cells are present.
(ii) Conjoint : In these vascular bundles xylem and phloem are present on the same radii. Conjoint vascular bundles may be collateral (phloem is present only outer to xylem) or bicollateral (phloem is present on both sides of xylem). If cambium is present between xylem and phloem then the vascular bundle is known as open, otherwise it is called closed.
(iii) Concentric : Those vascular bundles in which one type of vascular tissue is surrounded by another type are known as concentric vascular bundles. These bundles may be amphivasal or leptocentric(phloem is completely surrounded by xylem) or amphicribal or hardocentric (xylem is completely surrounded by phloem). Amphivasal bundles are found in Dracaena and Yucca. Amphicribal bundles are found in stamens of many dicots etc.
