Can someone please tell me EXACTLY what science concepts are?? And how they are connected to the deaths of orca whales.

ok ay new one

Explanation:

Scientific concepts can be described as systematic mental representations of the natural world, and they have a central place and role in science.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
