Answer:

The rock and fossil record shows that all of the changes in the Earth's history have been slow and gradual.

Explanation:

Rock and fossil record are of evolutionary importance, because these records gives ideas regarding the time since existence of life in Earth. This information can be used to to get a clear picture regarding how the living organisms of ancient age interacted with the environment of that time. The records thus obtained from rock and fossil are sufficient enough to conclude that evolution do are taking place which is very slow and gradual in such a way, so that it could provides for adaptability to the changing surrounding environment.

aniked [119]

Answer:

Independent variable: ALTITUDE

dependent variable: GROWTH OF PLANTS

Confounding variable: STOREYS OF THE BUILDING

Explanation:

In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.

- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.

- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.

- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.

Monica [59]

Answer:

West Nile virus (WNV) causes epidemics of febrile illness, meningitis, encephalitis, and flaccid paralysis. Since it was first detected in New York City in 1999, and through 2004, 16,000 WNV disease cases have been reported in the United States. Over the past 5 years, research on WNV disease has expanded rapidly. This review highlights new information regarding the virology, clinical manifestations, and pathology of WNV disease, which will provide a new platform for further research into diagnosis, treatment, and possible prevention of WNV through vaccination.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe
dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

  • To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
  • The equation can be written as, F= K \frac{ q_{1} q_{2} }{r^{2} } where k is the Coulomb constant, q_{1}  q_{2} are the point charges, and r is the distance between these two point charges.
  • To find the answer to this question, just substitute 2r in the place of r hence, you will get \frac{F}{4} as the new force when the distance is doubled.
