Answer:
1. B. carbon dioxide taken in from the surrounding air
2. A. Root
Explanation:
Sugar beet plant carries out photosynthesis and stores the excess of the sucrose in its taproots. During the process of photosynthesis, the plant absorbs CO2 from the air, water from the soil and synthesizes organic sugars in the presence of sunlight.
Atmospheric CO2 contributes carbon and oxygen atoms to the formed sugars which in turn are stored in plant parts. Therefore, atmospheric CO2 makes most of the mass of the photosynthesizing plants such as sugar beets. The taproots of beet plants are modified into storage roots to store the excess of the organic sugars.
The dendrites receive incoming signals while axons propagate signals away from the neuron cell body. The myelin sheath surrounds and insulates the axon.
Blue jays have caterpillars and mice as their food. An increase in the blue jay population will cause a decrease in the caterpillar and mice population since more blue jays will eat caterpillars and mice. As time passes, the blue jays will have a problem finding food since the caterpillar and mice population has decreased, so the blue jay population will eventually lower as well.
The answer is : b. Theoretically, noise pollution could be so great that it could kill a person. Noise pollution affect our sense of hearing... leading to hearing loss. It also disturb our sleep which could lead to fatigue. Long-term noise above a certain level can have a harmful influence on our health. Research shows that road traffic and aircraft noise increase the risk of high blood pressure. Noise pollution also affects wildlife, where animals depend wholly on their hearing for hunting.
