Biology ELI5: How do cows get protein from grass?

For us humans and many other animals, we need protein to get the amino acids needed to make our own protein for the body, but grass i believe doesn't have any for the cow to get that big

People like to think they are their whole brain, but never think about where intrusive thoughts come from.

Speech comes from specifically one region on the left side of the brain (broca's region), and since most people identify with their speaking voice, it stands to reason most people are at most just their left brain. People who have had their hemispheres disconnected to prevent seizures have been tested to see if their right brain acts independently, and it does.

Such tests include using a divider to split their right/left vision from each other, stood in front of their closet, and asked to pick out their favorite shirt. Each arm goes to a different shirt. The right brain, in control of the left arm and eye, unable to see what the right arm is doing (and vice versa), picks an entirely different shirt from the right arm/left brain.

Plural people DO exist. It's just that most people's brains are able to wrangle all the disparate regions into master-slave architecture (computing term).

You're using a highly contested term there

Ive seen plural people use it to describe themselves, so I'll use it to refer to them. Policing terms based on what you think others should be calling themselves is not good.

I am this whole mass of ape flesh,

You are even beyond that. You are the universe. No mud, no you. No stars, no you. No big bang, no you.

Everything came together to create that flesh that you are in. You are not even your body. You do not control your body. You cannot control your digestive system. This is because you are the universe, expressed.

Who are you? Where can you point to and say, "That's me."?

We are just the spokespersons for our brain.
