Females in polygynous species have larger home ranges than males. OD. Males in polygynous species have larger home ranges than females, while monogamous species have similar-sized home ranges for both sexes.

Sam Jones owns a granite stone quarry. When he acquired the land, Sam allocated $800,000 of the purchase price to the quarry's recoverable mineral reserves, which were estimated at 10 million tons of granite stone. Based on these estimates, the cost depletion was $0.08 per ton. In April of the current year, Sam received a letter from the State Department of Highways notifying him that part of his property was being condemned so that the state could build a new road. At that time, the recoverable mineral reserves had an adjusted basis of $600,000 and 7.5 million tons of granite rock. Sam estimates that the land being condemned contains about 2 million tons of granite. Therefore, for the current year, Sam has computed his cost depletion at $0.11 per ton [$600,000 ÷ (7,500,000 – 2,000,000)]. a. Is it proper for Sam to recompute a new cost depletion amount based on a revised estimate of the tons of granite stone remaining in the quarry? YesNo b. Sam should increasereduce the recoverable mineral reserves adjusted basis for the portion of the basisdepletion expenseloss allocable to the condemned land. Check My Work

Use the substitution method to solve the following system of linear equations. $\begin{cases} \frac{4}{1}x + \frac{1}{1}y = 13\\ \frac{8}{2}x + \frac{1}{1}y = 3 \end{cases}$ Write the solution as an ordered pair. For parametric solutions use either $x = t$ or $y = t$ as the parameter. (If an answer does not exist, enter DNE.) $(x, y) = $

A red sphere weights twice as much as a blue sphere. Both spheres are exactly the same size. When placed in a fluid, which of the following is true? Question 2 options: Both spheres would experience the same maximum buoyant force because they would displace the same amount of the fluid when completely submerged. The red sphere would experience a greater maximum buoyant force because it weighs twice as much and would displace twice as much liguid when fully submerged. The blue sphere would experience a greater maximum buoyant force because it weighs half as much and would displace half of the liquid when fully submerged. The red sphere would experience a greater maximum buoyant force because it weighs twice as much and would displace half as much liquid.

Excess streamflows are diverted past an urban sector through a 20 ft wide, 2 km long rectangular concrete channel designed to operate at a critical flow depth of 2.3 ft. Determine the following: a) The flowrate (cfs) capacity of the concrete channel at the critical flow depth, and b) The slope (%) required in the channel to maintain this critical flow depth. c) Bonus: Poor channel maintenance results in accumulation of debris, sediment and plants in the concrete channel effectively increasing the channel roughness to n=0.045. Estimate the channel flow depth (ft) under these conditions assuming it must still carry the flowrate computed in (a). Is the flow still 'critical', or is it sub-, or super- critical?
