Thyroid hormones regulate basal metabolic rate.
The hormone known as thyroid hormone regulates your body's metabolism, or how your body turns the food you eat into energy.Thyroxine (T4) and triiodothyronine (T3), the two primary hormones your thyroid secretes, together make up thyroid hormone.The thyroid gland creates hormones that control the body's metabolic rate, which affects bone growth and maintenance, heart, muscle, and digestive function.Thyroid hormones regulate the amount of energy expended during activity to the extent that people with thyroid disorders exercise more or less. They also have a direct impact on the basal or resting metabolic rate in humans and a permissive effect on small animals' adaptive thermogenesis.learn more about Thyroid hormones here: https://brainly.com/question/9251938

3 facts about Photosynthesis ?
Answer:
3 FACTS ABOUT PHOTOSYNTHESIS:
The chemical equation for photosynthesis is: carbon dioxide + water --> glucose + oxygenPhotosynthesis the process by which green plants and some other organisms use sunlight to synthesize (get or create) nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.Hope this helps!

Air that is present in the conducting airways, in terms of volume is the anatomic dead space.Inhaled air entering this area of the lung cannot participate in gas exchange because alveolar capillaries are blocked (e.g., by a pulmonary embolism), therefore it behaves just like air entering the conducting airways. The amount of respiratory zone air that is not involved in gas exchange, known as physiologic or total dead space, is equal to anatomic plus alveolar dead space. The respiratory bronchioles, alveolar duct, alveolar sac, and alveoli make up the respiratory zone.The figure shows empty space.

At the molecular level, cells from different types of organisms vary in their tolerance to temperature and pH. This variation can mostly likely be attributed to the types of enzymes present in the cells.
The tolerance ranges for abiotic environmental factors are similar to the geographic ranges that organisms have. To put it another way, they can tolerate (or survive in) a specific range of a given factor, but they cannot survive if the element is present in either an excessive or insufficient amount. Take temperature, for example. Polar bears thrive in cold climates but would perish in the tropics from excessive heat.Cells are incapable of acting as "liquid machinery" at temperatures below freezing and above boiling.
