Answer:

Option b, A catastrophic event where 90 percent of the ocean's species were lost and 70 percent of the land life was thought to go extinct.

Explanation:

In the Permian period large mass extinction of the Earth took place. This incident took place some 299 years ago.

The super continent Pangaea was emerging during the Permian period which caused severe extremes of climate and environment as it was extremely large in size. Much of the region was under ice caps and was frozen.

Nearly 90 percent of all marine species and 70 percent of all land animals became extinct.

Hence , option A is correct

A _____ is a measure of how much a typical serving size of a particular food raises blood glucose.​
kirill115 [55]
The correct answer is glycemic load.
In particular, glycemic load estimates the amount of carbohydrates in a serving of food and how each gram of these carbohydrates can affect the blood glucose. It is a measure commonly used in weight-loss programmes and in dietary programs used to treat insulin resistance. It has been shown that common spikes of blood glucose and insulin levels, increase the risk for diabetes.
