Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele
ki77a [65]

Answer:

51.84%

Explanation:

p² + 2pq + q² = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p²  = percentage of homozygous dominant individuals

q²  = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

p = 0.72 => p² = 0.72² = 0.5184

=> Percentage of the rats are normal sized: 51.84%

I need a poem about Photosynthesis and Cellular Respiration: has to have at least 20 lines and includes these words: ATP, Carbon
Neporo4naja [7]

Photosynthesis The Poem

I stand as a plant.

But what do I need?

I cannot make a sandwich

to feed.

But lucky for me

I have Photosynthesis, you see!

I take the Carbon Dioxide

And some water too

Altogether, I have Glucose for food

This gives me ATP energy

Which I need to survive

And so I do not come to my demise

But this also makes oxygen

Which I do not need

So I give it to humans so they can breathe.

Cellular Respiration is what they use

a little bit of oxygen

glucose tagging along too

they produce water and CO2

the mitochondria capture the energy

and use it

to power you so you can make tea!

My superpower may seem unreal

but it's not I promise

as crazy as it may feel.

My leaves grow big and strong

To reach out and soak up sunlight

that's far beyond.

I have organelles in my cells

that humans do not

They're called Chloroplasts just like you thought!

And they give me food like the chips you bought.

Chloroplasts take the suns light

And use it to make me food

like the glucose I eat every night!

Please don't laugh, I tried my hardest lol

Do whatever you'd like with it, take snippets of it or don't use it at all but either way I hope it helps a little!
