Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)

Answers

Isotopes have different mass numbers due to different number of neutrons  but same atomic number due to same number of electrons and protons.

What are isotopes?

Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.

Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.

They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable

Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .

Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.

when muscles contract, the ____ energy of ATP is used to drive the ____ energy of contraction

Answers

Answer:

1. Chemical energy

2. Mechanical (kinetic) energy

Explanation:

The contraction of our muscles is accompanied by movement. Contraction of muscles involves the proteins myosin and actin, which forms a cross-bridge. Calcium ions bind to troponin protein allowing the myosin to bind to the binding sites on the actin protein.

However, for this cross-bridge cycle between myosin and actin to occur repeatedly, ATP is needed to induce the release of the myosin from the actin active site. Therefore, When muscles contract, the CHEMICAL energy of ATP is used to drive the MECHANICAL energy (kinetic energy) of contraction.

NOTE: ATP supplies chemical energy to induce movement of muscles during contraction. Energy due to motion is called KINETIC ENERGY.

When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction ;  The missing answers are ; Chemical and Kinetic

When we contrast our muscles ATP induces the release of  myosin from its actin active site ( i.e. the use of the chemical energy contained in ATP ). the release of myosin leads to the contraction of the muscles, which is a form of mechanical/kinetic energy. The proteins involved in the contraction ( kinetic energy ) of muscles are myosin and actin while the calcium ion involved is troponin.

Hence we can conclude that When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction.

In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM​

Answers

Answer:

The Thermosphere

Explanation:

Just took the test on A P E X, it's right. Hope this helps :)

Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.

What are the different layers of the atmosphere?

The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.

In the troposphere, the temperature rises from bottom to top.  The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.

The atmospheric layers protect the life on Earth.

How do convection currents cause the motion of tectonic plates??

Answers

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Answer:

These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
