Answer:
Option B
Explanation:
The formal study of fossils, its collection and documentation started in 1700s during the period known as “Age of Enlightenment” It was during this time period that scientist noticed rock fossils and started making fossil collection. During the 1800s, areas with rocks fossils were studied and compared.
Further, Charles Lyell and Charles Darwin showed strong connection between biological evolution and geological evolution of planet earth. Hence, the earlier traces of fossils i.e before a certain period could not be studies due to late pioneering of fossil based evolutionary science. It is also due to limitations with radioactive dating
Hence, option B is correct
Answer:
Producers, consumers, and decomposers are organisms within ecosystems that are classified based on how they gain their nutrition
Explanation:
Producers such as plants make their own food, consumers such as animals eat plants and animals, and decomposers such as bacteria and fungi break down dead organic matter.
<em>The Great Barrier Reef in Australia is known as the largest coral reef in the world and the largest living thing on Earth where it houses countless species of sea animals. </em>
Its distinguishing or distinct abiotic feature is its shallow waters.
Sunlight is one of the most important factors in an ecosystem necessary for the organism's survival. The reef mostly has shallow waters so it is easier for the light to penetrate the water for the organisms to use. Even the reefs are visible from the outer space due to its shallow waters.
Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
