(Please help and actually answer please help ) Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survive; the perch do not.

Limiting factor-

Explain-

A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lake increases greatly.

Limiting factor-

Explain-

A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.

Limiting factor-

Explain-

Due to the introduction of rainbow smelt, Lake Winnipeg becomes crowded and some fish species do not survive.

Limiting factor-

Explain-

Since northern pike prey on yellow perch, an increase in the perch population causes an increase in the pike population.

Limiting factor-

Explain-

Many fish die due to an increase in water temperature.

Limiting factor-

Explain-

Due to over-fishing, the number of walleye in Lake Winnipeg decreases.

Limiting factor-

Explain-

A population is growing quickly when parasites cause disease to spread quickly.

Limiting factor-

Explain-

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
