C is the answer to the question
Answer:
1) Inti menghilang.
2) Kromatid menuju bidang ekuator.
Penjelasan:
Selama fase pertama mitosis i. e. profase di mana replikasi menjadi kromatid terjadi dan berubah menjadi kromosom sementara nukleolus menghilang dan terjadi pemecahan selubung inti. Setelah profase, metafase dimulai di mana kromosom menjadi terlihat di sitoplasma sel dan bergerak menuju tengah atau ekuator sel.
The enveloped virus make the cell think that they just found a jackpot of protein, only to find a virus inside to take over the system, like the trojan horse.
The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.
