Hope it helps
Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.
You arrive at this conclusion because your classmate "and his sister are both much shorter than their parents."
Explanation:
As we start getting older, the bones begin to become thinner. Respectively of the vertebrae converts to become a little shorter. Therefore, so do we. With full-blown osteoporosis, people can lose several inches in height. The average height of a woman in the U.S. is about 5 feet, 4 inches, up about an inch in the last few decades, according to the Centers for Disease Control and Prevention. The study adds to growing interest in early-life events that influence adulthood.
High tides and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth and its water to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.
