Adding and removing energy can change the physical properties of a substance.

Biology
1 answer:
postnew [5]3 years ago
3 0

Answer: True.

Explanation: Energy is being removed from the substance as it changes state. As energy is added to the liquid, particles throughout the liquid move faster. Boiling. When particles move fast enough to break away from other particles, they evaporate and become gas.

The textbook the quantum efficiency for photosynthesis decreases abruptly when the wavelength of light being used becomes longer
Elis [28]

Answer:

The correct answer will be option- A

Explanation:

Red drop effect is the effect observed by the light present in the spectrum of the wavelength of red light. The effect is observed with the decrease in the quantum yield of the oxygen formed per quantum of light when the wavelength of light exceeds 680 nm.

The decrease of quantum yield is observed due to the fact that the oxygen is formed by the breakdown of the water molecule during light-dependent reaction which is initiated by the PS II which begins the chain at 680nm.

If light exceeds the 680 nm then, PS II will remain inactive and thus will abrupt the dissociation of the water molecule and thus the formation of oxygen during the light-dependent phase.

Thus, option-A is the correct answer.

Molecules that do not contain carbon Are <br> called in organic true or false
dem82 [27]

I would say True,But that is a hard one as all molecules that do not contain carbon are called inorganic molecules. Hopefully that helps you ❤

What is the difference between evaporation and transpiration?
miskamm [114]
Evaporation takes place when the sun's heat breaks the bonds with water in liquid form which happens to be in an ocean, lake, stream , or puddle, it is then draw into the atmosphere while it is in a gaseous state. Transpiration is for lack of a better word, plants sweating. Plants release small amount of water which are then usually evaporated or used by the plant.

SUNLIGHT
Mazyrski [523]

Answer:

"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.

"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.

These statements are true, however:

SUNLIGHT

CARBON DIOXIDE

WATER

MINERALS

OXYGEN

PLANT SUGARS

Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.

Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).

Is the lumen of an artery, capillary or vein, large or small? Why?
SOVA2 [1]

Answer:

Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.
