Answer:  D. In the ocean

A watershed can be defined as regions of land where all surface water drains into the same place. It is a land that is occupied with water drained from interconnected  rivers, and lakes.  These drainage streams may aggregate in the ocean.

According to the above information the open watershed system likely to dispense off tritium in the ocean because the open watershed water may flow and combine with other reservoirs of water like ocean.

What is the mass in grams of a pure iron cube that has a volume of 4.60 cm3
yuradex [85]
In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³

Now,

Density = mass / volume

Mass = density * volume

Mass = 7.87 * 4.6

36.2 grams of iron are present in the cube

Scientists are studying animals in a large lake area. In this lake area, both owls and raccoons eat ducks, and ducks eat frogs.
Stolb23 [73]

Answer:

Population of duck and frog will change with the change

Explanation:

The complete question is

Scientists are studying animals in a large lake area. In this lake area, both owls and raccoons eat ducks, and ducks eat frogs. The data shows that recently the size of the raccoon population decreased. How will the decrease in the raccoon population affect the other populations? Be sure to explain whether the owl population, the duck population, and the frog population will change, and why.

  1. Owl population will change
  2. Duck population will change
  3. Frog population will change

Solution

Raccoon eat duck and duck eat frog. Now if the population of Raccoon decreases then the number of predators of duck will decrease thereby increasing the population of duck.

The higher will be the number of ducks, the more frogs they will consume thereby decreasing the population of frogs

Hence both the population of duck and frog will change with the change
