The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.
Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)
And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"
Hence, option C is correct

d. budding
Explanation:
Budding is a type of asexual reproduction, as are binary division, multiple division, vegetative propagation, and fragmentation. This type of reproduction is observed in some species of animals and plants.

This type of reproduction is common in several plant species, occurring more frequently in angiosperms, and also in some animal species, especially in the cnidarian and porifer group.
<h2>Answer:</h2>

Explanation:
DNA deoxyribo nucleic acid is the nucleotide sequence which is the blue print of the structural and functional characteristics of the whole organism.
Nucleus of the call is very small to be contain the DNA of cell. So DNA is present in the condense form by wrapping around the histones proteins which is known as cell division.
At the time of cell division, it is present in chromosomal form to equally divide the genetic material.
