glycogen, carbonic acid, lipase, or lactic acid

I am not quite grasping onto this concept. I'm reading "Red blood cells carry a protein called hemoglobin that actually contains the oxygen. Hemoglobin is a iron containing pigment and iron is an "enabler". Why do we need hemoglobin and why do red blood cells need them? Why can't red blood cells/erythrocytes just carry oxygen itself?

I understand that they exchange nutrients and wastes and theyre really small in diameter and allow for diffusion but what are they diffusing? and is the blood passing from the arteries to the veins the waste oxygen poor blood? because dont veins contain deoxygenated blood. As well, I dont t understand what hydrostatic pressure and osmotic pressure mean please help i hate bio and this concept

All my biology notes for the digestive system mention secretion and I have no idea what that means. Could somebody explain it? Thank you.

I've been working at this job for I would say a good three weeks and I've hated every minute of it. I do not feel like I am excelling in my workplace and some workers are particularly nasty to me. As well, I asked for full time when I was hired and I got 10 hours and I got an entire week off.... On top of all of that, my pay check is literally minimum wage. I am pending on a position from another company but regardless or not I get hired there I just want to leave this job as soon as possible. My next shift is on Friday and after that I work the following 3 days (surprise around when I start to quit I get more shifts but still minimum wage job and I cannot deal with the people I work with) and I plan on handing in a resignation after my shift on Friday. If I say that I have been offered employment at another company can I immediately resign. I know it is putting them under tight spot and it is not courteous of me to inform them so late but I could not do it any sooner because I didn't have any shifts and going to work and back would take two hours for a couple minutes. Sorry for that long rant and I know how unprofessional that sounds but am I able to immediately resign?

I have to use tener que which is to have to people might have different ways of saying that but that's what I have to use for my class. Thank you in advance!

chaucer has been deemed by many schooars to be the first major english poet.

many writers have been influenced by chaucer's bawdy humour and insight characterizations.

i think the canterbury tales can justifiably be called the most popular work in english literature.

and wht is the difference between active and passive im so confused
