What happens when we do expiration/exhale?
External intercostal muscles relax

Which of the following explains the event in light-dependent reactions?
Light-dependent reactions happen during the night to lessen
There is a series of excitations or jumping of protons from one photosystem to the other.
The water molecules combine, releasing hydrogen crucial for the atmosphere and respiration.
Pigments like chlorophyll absorb light energy, propelling electrons in photosystems.
Which of the following is TRUE about light-independent reactions?
Light-independent reactions occur during the day to maximize the collection of light energy required to create ATP.
It uses ATP and photosystems to produce organic compounds through a biochemical pathway.
Carbon atoms from carbon dioxide are bonded or fixed into carbohydrates.
Light energy obtained during light-independent reactions is converted to chemical energy in the form of glucose.
Which of the following factors significantly affect the rate of photosynthesis?
Source of carbon dioxide and hydrogen molecule
Fluctuating temperature and light intensity
Concentration of minerals absorbed by the roots
Amount of stomata found in the leaves
(a) works with platelets in the blood to form blood clots.
What do light-independent reactions need to work?
Light, H2O, NADPH
ATP, NADPH, O2
CO2, NADPH, ATP
NAD+, ATP, CO2
6 (a) + 6H2O --> C6H12O6 + 6O2
Pyroclastic flow is the aftermath of an effusive eruption.
True
False
Changes in Earth's orbit and the tilt of Earth's axis affect the distribution of solar radiation.
True
False
Which of the following statements proceed after glycolysis occurs?
The oxygen combines with the hydrogen ions and electrons to form water.
The molecule enters the matrix of the mitochondria and carbon dioxide is removed, which forms an acetyl group.
The electrons transfer their energy to the proteins in the membrane, providing the energy for hydrogen ions to be pumped across the inner mitochondrial membrane.
The flow of the ions back across the membrane synthesizes ATP by a protein called ATP synthase.
What kind of eruption do cinder cone volcanoes have?
effusive
explosive
lava
phragmatic
All arteries carry oxygenated blood.
True
False
Volcano conduits are openings on the earth's surface through which volcanic materials are released.
True
False
Globulin provides (a)
When you add yeast and sugar to water, after some time, a foam will form. What causes this foam?
CO2 caused by cellular respiration (fermentation)
O2 caused by fermentation
CO2 caused by photosynthesis
None of the above
Why does the diaphragm contract when we breathe in?
To make more room for the lungs which volume increases due to the air
To support the lungs' weight
To decrease the air pressure so air flows into our lungs
To support the ribcage
Red blood cells cannot cell divide.
True
False
In which type of blood vessel does gas exchange occur?
Arteriole
Vein
Capillary
Artery
When a meteoroid enters the Earth's atmosphere and starts burning, it's called a (a)
[Correct the word written in all capital letters.]
The VENTRICLE accepts blood into the heart.
Atria
It's already correct
Semilunar valve
Veins
