What is the main difference between active and passive transport?

Biology
1 answer:
Dovator [93]3 years ago
8 0

Answer:

B)the energy required

Explanation:

The difference between active and passive transport is in the amount of energy they both require.

  • Active transport requires energy to move molecules such as ATP and ions against a concentration gradient.
  • Passive transport moves molecules from higher concentration region to one with lower concentration without requiring energy.

Energy is the ability to do work. In passive transport, energy is not used. But in active transport, energy is required.

Mid-ocean ridges are segmented and contain which two basic types of plate boundaries linked together?
mamaluj [8]
Mid ocean ridges occur where two tectonic plates diverge or move away from each other. This separation occurs under the ocean.The Mid-Atlantic Ridge is such an example and is where the North and South American plates pull away from the Eurasian and African plates. Mid ocean ridges are usually a combination of divergent and transform plate boundaries. At transform boundaries plates slide past each other in opposite directions.

An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
Pie

Answer:

B. 18

Explanation:

An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.

However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.

Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:

Neutron no. = mass no. - proton no.

Neutron no. = 35 - 17

Neutron no. = 18
