<h2>c) is the correct option</h2>

Explanation:

Inhibition of Cdk activity occurs by Cdk inhibitory protein (CIPs)

  • A group of specific proteins called CIPs binds with active cyclin Cdk complex and cause their inactivation
  • Activated protein retinoblastoma (p53)act as transcriptional factor and induce synthesis of Cdk inhibitory proteins p21CIPs
  • p21CIPs is a Cdk inhibitory protein that binds and inhibit the activity of G1 Cdk cyclin complex as a result cell cycle arrest in G1 phase

During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.

Explanation:

Prophase is divided into 2 sub-phases as early Prophase and late prophase.

Early Prophase:

In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears

By late prophase:

Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.

Metaphase will follow the prophase.

Why cant most stars can make elements like gold and iron
balandron [24]

When a star is fusing iron in its core, it's still giving off insane amounts of energy. ... Iron cannot be fused into anything heavier because of the insane amounts of energy and force required to fuse iron atoms. The atomic structure of iron is very stable, more so than most other elements.

What are your thoughts about how the universe formed?
V125BC [204]

 For centuries scientists thought the Universe always existed in a largely unchanged form, run like clockwork thanks to the laws of physics. But a Belgian priest and scientist called George Lemaitre put forward another idea. In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today.

His idea went largely unnoticed. But in 1929 astronomer Edwin Hubble discovered that the Universe isn’t static but is in fact expanding. If so, some scientists reasoned that if you rewound the Universe's life then at some point it should have existed as a tiny, dense point. Critics dismissed this: the celebrated astronomer Fred Hoyle sarcastically called this concept the “Big Bang Theory"
