Earth's core acts as a source of heat in the mantle and results in mantle convection.

Answer: Option D

<u>Explanation:</u>

The earth is divided into three layers namely the outer crust, the middle mantle and the inner core. The inner core layer of the earth has very high temperature due to which it is very hot and it acts as source of heat for the middle layer mantle.

Mantle convection is the moderate crawling movement of Earth's strong silicate mantle brought about by convection flows conveying heat from the earth’s core to the earth’s crust. Thus the Earth's core acts as the heat source for mantle.

How were aristotle's and linnaeus classification systems different?
DanielleElmas [232]
Both Aristotle and Linnaeus classified animals and plants, considering where the species lived. However, Linnaeus delved further into classifying organisms looking at their morphology, with an ordered subset of the organism's class divided into five kingdoms: class, order, species, genus, and variety. The process of this classification is called Taxonomy, however, modern scholars also consider the evolutionary history of a species, in the classification process.

Polycystic ovary syndrome is an endocrine disorder and a common cause of chronic anovulation. In addition to the clinical manife
Scilla [17]

Answer:

1. Insulin resistance and diabetes

2. Metformin

Explanation:

Metformin can be used to treat polycystic ovary syndrome, especially for insulin-resistant women (insulin is a hormone that transports sugar into cells).

People with insulin resistance have high levels of this hormone in their blood and excess circulating insulin can aggravate manifestations of polycystic ovary syndrome, and also increase the risk of diabetes.

The main benefits of metformin in the treatment of polycystic ovaries is the normalization of menstrual irregularity and the restoration of ovulatory cycles.

Since most women with polycystic ovary syndrome are insulin resistant, metformin is a good treatment option in some cases.

However, the treatment of polycystic ovary syndrome should be individualized for each woman, depending on the symptoms presented and the goal to be achieved with the treatment.
