In a flashlight, the chemical energy in batteries is changed to ______________________ energy and ________________________ light.
Group of answer choices
thermal, mechanical
EM, nuclear
thermal, EM
EM, sound
Answer:
the answer should be thermal energy
Explanation:
Batteries can convert stored chemical energy into electrical energy. ... Electricity can be transported through wires to places where it is needed and then converted into other forms. In a flashlight, the electrical energy becomes light energy and thermal energy in the bulb.
How does greenhouse effect, affects biodiversity and gradual extinction
Answer:
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze.
Explanation:
As an electron approaches a proton, what happens to the electric force of attraction between them? (1 point) Group of answer choices Remains the same Increases Decreases It ceases to exist
Answer: increase
Explanation: cause ik
Answer: It increases
Explanation: As an electron goes near a proton, the force of attraction would increase. Electron is negatively charged while the proton is positively charged so they would naturally attract each other.

How is the difference in the walls of the atria and ventricle related to the different functions of the atria and ventricle?
Answer:
The atria are thin-walled sacs that receive blood from the body or lungs, while the ventricles have a thick muscular wall because they must pump the blood with greater pressure than the atria.
Explanation:
In the human heart, the atria and ventricles are responsible for handling blood and have different structures and function.
The atria are thin-walled sacs located at the top of the ventricles and their function is to receive the blood that comes from the whole body —right atrium— or from the lungs —left atrium— to pass it to each ventricle through the atrioventricular valves, which does not require much pressure. On the other hand, the walls of the ventricles are made up of a thick layer of muscular tissue, since the pressure with which they must pump the blood -towards the lungs or to the entire organism- is greater than that of the atria.The structure of each chamber of the heart is configured to be able to fulfill the specific function that they possess.

What shift in population growth has occurred by point A?
1 The birth and death rates are equivalent.
2 The rate of emigration equals the death rate.
3 The population sizes of the organism and its predator are equalized.
4 There will be more food available than the populations can consume.
The shift in population growth has occurred by point A is The birth and death rates are equivalent.
How does birth rate and death rate affect population growth?Population alteration is controlled by the balance between birth rates and death rates.
Suppose the birth rate stays constant and the death rate decline, then population numbers will increase.
whereas If the birth rate grow at a faster rate and the death rate stays the constant, then population will also increase.
Thus, option "A' is correct, The birth and death rates are equivalent.

What would happen if the Golgi bodies in the cell were destroyed?
The cell would not be able to digest or break down the materials left over from protein creation.
Explanation:
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn't be able to live for very long.

What kind of bonds hold the phosphate groups together in ATP and ADP? Exxplain please
Answer:
These phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
