Answer:

There is a high positive correlation between sleep and exam performance.

Explanation:

The concept of correlation indicates an association, that is to say, it is used for measuring how much two variables relate to each other. The 3 results of a correlational study are positive, negative, and no correlation. A positive correlation takes place between 2 variables that can increase or decrease together.

lutik1710 [3]

Answer:

Explanation:

Southeast/Southeastern Asia is a region of the Asian continent that consists of countries located east of India, south of China, north of Australia, west of New Guinea, and south of China. 11 countries make up Southeast Asia.The region is bordered by East Asia to the north, Bay of Bengal and South Asia to the west, the Pacific Ocean to the east and the Indian Ocean to the south. A large part of Southeast Asia is located in the Northern Hemisphere but a smaller part lies within the Southern Hemisphere.

Southeast Asia consists of two regions. Mainland Southeast Asia is historically known as an Indochina and consists of Laos, Vietnam, West Malaysia, Thailand, Myanmar, and Cambodia. Maritime Southeast Asia is historically referred to as the Malay archipelago and East Indies consist of Indonesia, East Malaysia, Philippines, Singapore, Brunei, East Timor, Christmas Island, Cocos Island, and in some instances Taiwan.

Geography Of Southeast Asia

Southeast Asia is located close to the intersection of tectonic plates that experience frequent volcanic and seismic activities. A large part of the region lies on the Sunda Plate except for Northern Vietnam, Northern Thailand, Myanmar, and the Northern Luzon region of the Philippines. The mountainous region of Thailand, Myanmar, and Peninsular Malaysia are located on the Alpide belt, while several islands of the Philippines make up part of the Pacific Ring of Fire. Both seismic zones converge in Indonesia making the country susceptible to volcanic eruption and earthquakes. Mount Hkakabo Razi in Burma is the highest mountain in Southeast Asia with a height of 19,295ft. The South China Sea and the islands on it is a major source of conflict among the countries of Southeast Asia and China.

"Biodiversity is fundamental to human welfare and economic development and plays a critical role in meeting human needs by maintaining the ecological processes upon which our survival depends" is True.

<u>Answer:</u> Option A

"Biodiversity" is the life on Earth's range and difference among them. It is the measure of variation typically in a genetic, species, and ecosystem level.

The economical development promoted by biodiversity is understood from following ways:

  • Deforestation may result into soil erosion and desertification, which decline the ability of a nation or region to grow crops and in turn may lead to resource and economic dependency on other countries.  
  • Biodiversity-rich areas provide a pleasant, enticing climate and are able to promote tourism.
  • Ecological phenomenon such as primary production affects the limit, distribution, and system's biodiversity. The down fall of primary production leads to the flow of energy to higher tropic levels which may impair the feasibility of food-dependent animal populations.
