1. What was the independent variable in this lab? *

1 answer:

4 0

I can’t give you a specific answer because I’m not sure what your lab is. However, an independent variable is the variable that is changed, the dependent variable is the variable that is affected by the change, and the constant variables are those which remain the same throughout the entire experiment.

Which statement accurately compares these flashlights?

RoseWind [281]

The smaller flashlight has less inertia than the larger flashlight, so it takes

less force to change the motion of the smaller flashlight.

Inertia is defined as the property of an object to resist changes in its velocity

when in motion. A larger or bigger body has more mass and inertia as it

requires more force to change the direction of the object.

The smaller flashlight has less inertia than the larger flashlight and hence

requires less force to change its motion due to its smaller size.

Consider the classifications of bone, and examples of each. which classification applies to bones used primarily for movement ra

-BARSIC- [3]

Long bones are used primarily for movement rather than protection. A few examples of long bones are the humerus, tibia, and phalangeal bones.

The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.

Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones. Bone remodeling involves the processes of bone deposition by osteoblasts and bone resorption by osteoclasts.

Nat2105 [25]

Answer:

Explanation:

1. Hydrological cycle: the continuous movement of water between the Earth's surface and the atmosphere.

2. Industry: pollutes water sources by dumping wastes in rivers, streams, and oceans.

3. Sewage: the leading cause of water contamination in countries without water treatment plants.

4. Agriculture: a source of water pollution caused by the overuse of pesticides and fertilizers.

5. Eutrophication: caused by an overabundance of organic matter in water supplies.

6. Putrefaction: the decomposition of organic matter by microorganisms

7. Pesticides: a chemical pollutant that can enter the water cycle through agricultural or domestic use.

8. Petroleum: can cause the contamination of underground water supplies if poured on the ground

9. Lead: a metal that leaks into water supplies via the soil or aging water systems.

10. Humoral immunity: depends upon the production of disease-specific antibodies to destroy harmful bacteria.

11. Stimulants: increases the activity of the central nervous system.

12. Depressants: reduces the activity of the central nervous system.

13. Bacterial infection: caused by the reproduction of a small infectious agent, which produces poisons that destroy cells
