Explain why volcanoes form at both convergent plate boundaries and divergent plate boundaries.

Answers

Answer:

Volcanoes often form along tectonic plate boundaries where oceanic plates sink beneath other plates. As a plate sinks deep into a subduction zone, it will start to heat and melt, forming something called magma. Volcanoes can also be created near tectonic boundaries where plates pull apart. This allows magma to rise up from the mantle.

If distance=rate x time, which of the following must also be true?
A- rate= distance x time
B- time= distance/rate
C- distance= rate/time
D- time= rate/distance

Answers

D is the correct answer I believe it is correct

If distance = rate x time

then,

Time = Distance/Rate

Hence, Option B is correct.

Time is directly proportional to distance.

What is meant by Rate?The ratio of two related numbers expressed in several units is known as a rate in mathematics. If one of these numbers is used as the ratio's denominator and it is assumed that this quantity may be modified in a predictable way (i.e., is an independent variable), then the numerator of the ratio represents the rate of change in the other (dependent) variable.Speed, heart rate, and flux are examples of common rates that are expressed as "per unit of time." Exchange rates, literacy rates, and electric field are a few ratios that don't need time as the denominator (in volts per meter).A rate that is defined using two numbers of the same units will provide a dimensionless quantity that can be stated as a percentage, fraction, or multiple. Examples of these rates include tax rates and literacy rates.

Which best describes why active transport requires atp to move molecules across the cell membrane?




A. Molecules are moved with the concentration gradient

B. Molecules are moved against the concentration gradient

C. No net movement of molecules needs to occur

Answers

Answer:

B. Molecules are moved against the concentration gradient.

Explanation:

Due to the higher concentration of the molecules of one of the sides than the other,in order to move molecules from the side with higher concentration of molecules to the side of lower concentration of molecules which is against the movement of molecules across the membrane, energy must be applied i.e atp.

The reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.

ACTIVE TRANSPORT:

Active transport is a type of cellular transport that requires the input of energy in form of ATP. Examples of active transport are pumping of Na+/K+ ions, exocytosis etc.

Active transport requires ATP because molecules are being moved against concentration gradient. This means that molecules are moved from regions of low concentration to that of high concentration.

Passive transport, which does not require energy, moves molecules down a concentration gradient.

Therefore, the reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.
