Scientists use a model because the continents move to slow to observe directly. The continents move about 2in per year along plate boundaries. That 2 inch movement is too small to be observed directly that’s why we use technology in order to measure the movement

As a character of all living things, homeostasis relates most directly to which of the following biological themes
Novosadov [1.4K]

Explanation:

As a characteristic of all living things, homeostasis relates most directly to which of the following biological themes?

A.) Interacting systems.

B.) Stability.

C.) Evolution.

D.) Scale and structure.

Correct: B.) Stability.

During homeostasis the body maintains a constant internal balance (stability) in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.

Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

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.
