Answer: 5. Adenosine triphosphate (ATP) consists of an adenosine molecule bonded to three phophate groups in a row. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work. Now its back to being ADP and is ready to store the energy from respiration by bonding with a 3rd phosphate group. ADP and ATP constantly convert back and forth in this manner.

6. Active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.

explanation: simplify 5. in your own words.

Electrically charged sunspot gases which escape the sun's chromosphere and enter the earth's atmosphere near the magnetic north

Kisachek [45]

Answer:

Northern Lights ( Aurora Borealis)

Explanation:

When the electricaly charged sunspot gases (they are named a solar wind) escape the sun's chromosphere and penetrates from the earth magnetic sheild which is called earth's magnetosphere then upon there interaction with atoms and molecules of our atmosphere there are little bursts of photons in the form of light which made up these northern lights.

Duplain St. is 300 m long and runs from west to east between Baron and Burkey. If Keith is strolling east from Baron at an avera

Ivahew [28]

Sue from Burkey and Keith from Baron will meet in 2 minutes

Answer: Option b

<u>Explanation:</u>

Time taken can be calculated when distance and the speeds are given. Here speeds of Keith and Sue are given. So, we have to find the relative speeds in order to calculate the time taken.

When two objects travel in same direction the relative speed will be the difference between speeds. Similarly when two objects travel in opposite direction, the relative speed will be the sum of given speeds.

Given:

Speed of Sue from Burkey is 6 km/hr and speed of Keith from Baron is 3 km/hr.

The distance between Burkey and Baron is 300 m.

From the formula, $d=s \times t$

where d is distance,s is speed and t is time

It can be derived that, $t=\frac{d}{s}$

s = sum of given speeds = 3 km/hr + 6 km/hr = 9 km/hr

d = 300 m = 0.3 km $\text {Time }=\frac{0.3 \mathrm{km}}{9 \mathrm{km} / \mathrm{hr}}=\frac{1}{30} h r=2 \text { minutes }$

Explain how forces of attraction and repulsion exist within an atom. describe how an electric charge is developed by friction or

dalvyx [7]

There are three kinds of forces within the atom:

i) Electromagnetic force of attraction between the electrons and protons

ii) Electromagnetic force of repulsion between the protons or weak nuclear force

iii) Strong nuclear force between the electrons and protons

<h3>What is nuclear force?</h3>

The electromagnetic force of attraction:

Electrons circle in the orbits above the nucleus. There exists an electromagnetic force of pull between the electrons and protons. That’s why electrons do not depart the atom.

Weak nuclear force:

It is an electromagnetic significance of revulsion between the protons in the nucleus of the atoms.

Strong nuclear force:

This force is strongest from all the fundamental details and exists between the protons and neutrons in the nucleus of an atom. This pressure overcomes the weak nuclear force and does not allow protons to stray out.
