1. The Meninges are three protective membrane layers surrounding the Brain and spinal cord.
2. CSF occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord.

Gibberellins break dormancy in seeds and produce an elongation of the stem by increasing the length of the internodes.

The different refractive mediums of the eyeball are:

Aqueous chamber (Aqueous humour) → Lens → Vitreous Humour.

During Meiosis cell division, the significance of the following two phenomena are:

1. Reduction in the number of chromosomes: The chromatids of each chromosome get separated. Therefore, in meiosis, the final product gets half the number of chromosomes of the mother cell. This led to the formation of gametes.
2. Exchange of segment between chromatids: Exchange in the segment between two chromatids gives birth to new variations in the offspring.

1. Metaphase
2. Anaphase
3. Prophase
4. Anaphase

Here are two characters having opposite traits that Mendel selected to establish the law of segregation in pea plants:

• Flower colour: Purple and white
• Seed shape: Round and wrinkled

X°X - Carrier woman.

X°Y - Colour blind man.

Result - 50% of daughters colour blind

50% daughter carrier.

Conclusion - The born female baby may be colourblind or carrier possibly - 50% checkerboard.
