Answer:

Down's syndrome

Explanation:

Down's syndrome is caused by trisomy of chromosome 21. Trisomy refers to the presence of three copies of one chromosome in the genome. Since David has extra genetic material in chromosome 21, he is suffering from Down's syndrome.

Down's syndrome would affect the mental development and learning process of David. He is likely to have a broad skull with a small mouth.

Why are the colors different on the planet at different times of the year ? Give a specific example.
Reptile [31]

Answer:

In the Northern Hemisphere, ecosystems wake up in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves — and a fleet of Earth-observing satellites tracks the spread of the newly green vegetation.

Meanwhile, in the oceans, microscopic plants drift through the sunlit surface waters and bloom into billions of carbon dioxide-absorbing organisms — and light-detecting instruments on satellites map the swirls of their color.

Satellites have measured the Arctic getting greener, as shrubs expand their range and thrive in warmer temperatures. Observations from space help determine agricultural production globally, and are used in famine early warning detection. As ocean waters warm, satellites have detected a shift in phytoplankton populations across the planet's five great ocean basins — the expansion of "biological deserts" where little life thrives. And as concentrations of carbon dioxide in the atmosphere continue to rise and warm the climate, NASA's global understanding of plant life will play a critical role in monitoring carbon as it moves through the Earth system.

Give reasons why the energy level decrease as you move down a food chain..
avanturin [10]

Answer: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels. or in materials that the consumer does not digest, or  through movement
