I am a single-celled, prokaryotic organism that lives in the large intestines of mammals
like humans. I reproduce asexually by binary
fission and can reproduce this way very fast.
What kingdom do I belong to and what’s my organism name?

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
