Answer: Fish A because of its elongated body and powerful tail.

Explanation: An elongated body gives the fish a streamlined or fusiform shape. This enables them to slide more esily through water, thus decreasing the energy expenditure of the fish for swimming. Powerfull tails also enables them to swim over long distances as well as bursts of speed. This speed capability is vital when the fish will either try to avoid a predator or, if it is a predator itself, catch its prey.

Which of these are the two major sources of nitrate pollution in rivers? the burning of fossil fuels by factories and cars anima

Mekhanik [1.2K]

Answer:

animal wastes and fertilizers

Explanation:

The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.

The owner of a tree farm decides to harvest a stand of mature white pine trees. Each white pine yields approximately 62 board fe

adelina 88 [10]

Answer:

$13764 ; $247752 ; $173426 ; $259740

Explanation:

1 white pine = 62 board feets

Density of white pine = 120 trees per acre

Wholesale price per board foot = $1.85

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(62 * 120 * $1.85) = $13,764

B.) Amount Realized on harvesting 18 acres

Value per acre * 18

$13764 * 18

= $247752

C.)

Amount charged by timber company = 30% of wholesale price

Total wholesale amount realized on 18 acre = $247752

Amount left after paying timber company :

$247752 - (0.3 * $247752)

= $173426.4

= $173426 (nearest dollar)

Amount made now : = $247752

After 10 years :

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(127 * 120 * $1.85 * 18) = $507492

$507492 - $247752 = $259740
