Okay, pyramid of Biomass refers to the energy levels and amount of energy available at each trophic level. Theses pyramids are always broader at the base and have narrow tops because energy is lost as it is passed from one level to another. Pyramids of number, as the name states tell us about the number of organisms at each trophic level. They can be wider at the base as well as narrow depending on the source. For example if there is a tree at the base of the pyramid of numbers then the base would be small because a single tree is consumed by many insects etc. But if there is grass at the base, a lot of grass is consumed by few goats, so base is wider.
thanks :D

What is the function of Thyroxine hormone????????????????,i do not remember it.help me!!!!!!!!!!!
The thyronines act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth (synergy with growth hormone) and neural maturation, The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. They also stimulate vitamin metabolism. Numerous physiological and pathological stimuli influence thyroid hormone synthesis. #copied

The answer is B. Why does the volume of the gas in the balloon increase?

Because due to the air pump, air gets sucked out, decreasing the pressure of air in the jar. Less pressure is exerted on the balloon which causes it to expand. The volume of air inside it increases, and when Volume increases the Pressure decreases. (Boyle's Law)
