Answer:
<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>
Explanation:
As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.
Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
Anaphase 1. It’s also the only answer where the chromosomes themselves separate.

Explanation:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.
The single type of bacteria is not adequate to make any conclusions.
Answer:
The correct answer is between the arachnoid and the pia. Thus option 'a' is correct.
Explanation:
Subarachnoid hemorrhage is the bleeding in the brain more precisely in the subarachnoid space-the space between the arachnoid and the pia matter surrounding the brain.
The layers that surround the brain termed as meninges of the brain of the brain include:
1) Dura matter the outermost layer close to the skull.
2)Arachnoid matter.
3) Pia matter, the innermost layer that is in contact with the brain.
A subarachnoid hemorrhage can occur due to many causes such as an accident , ruptured aneurysm, e.t.c. It is a life threatening condition and is accompanied with stroke.
