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).

lesya692 [45]

Answer:

1s2 2s2 2p4

Explicación:

1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.

Olenka [21]
GAGTTA is what you have.
CTCAAT is what you’ll get.
A matches with T, G matches with C, and U is only for translating out of the DNA sequence.
