Biology

Mandarinka [93]3 years ago
4 0

Answer:

Chromosome number in gametes- haploid (n)

Chromosome number in zygote- diploid (2n)

Explanation:

Sexually-reproducing organisms make use of gametes to reproduce. The gametes are produced via the process of meiosis, which is a cell division that results in daughter cells (gametes) that have their chromosomal number reduced by half. A diploid (2n) organism i.e. possess two set of chromosomes undergoes meiosis to produce haploid (n) gametes i.e. contains one set of chromosomes. The male parent produces haploid sperm while the female parent produces haploid egg.

During reproduction, these haploid gametes (sperm and egg) combine in a process called FERTILIZATION to produce a diploid ZYGOTE. The diploid zygote then divides and grows into the full organism. Hence, since a zygote is formed by the fusion of two haploid gametes (sperm and egg), it contains a diploid chromosome number i.e. sperm (n) + egg (n) = zygote (2n)

The brain ventricle located in the diencephalon is the _____ ventricle.
BaLLatris [955]
<h2>The brain ventricle located in the diencephalon is the <u>third</u> ventricle.</h2>

Explanation:

Brain Ventricles:

  • Ventricles are the communicating network
  • It is filled with CSF (cerebrospinal fluid )
  • This is responsible to transport the above fluid around the cranial cavity.

Ventricle system consists of "2 lateral ventricles", "the third ventricle", "the cerebral aqueduct", and the "fourth ventricle".

diencephalon:

  • This is the division of fore brain.
  • This relays sensory information
  • Controls autonomic functions
  • It is also termed as "between brain" or "interbrain"
