3 types of neurons in the neural layer of the retina - photoreceptors, bipolar cells, and ganglion cells Abnormal ECG examples - arythmia, Afib, Vfib, bradycardia, and tachycardia accommodation - change in the shape of the eye Agglutination - clumping of blood; happens when antigen and antibody react if not matched Albumins - Transport fatty acids and steroids, help regulate osmotic pressure of the blood. Anemia - A condition in which the blood is deficient in red blood cells, in hemoglobi...

"Biologists practice evidence-based decision making." This statement means that: Biologists start by stating a hypothesis and a null hypothesis, without making prior observations because that might lead to bias. Biologists select between a hypothesis and a null hypothesis based on careful thought without data Biologists select between a hypothesis and a null hypothesis based on experiemental or observational data Only careful experimentation allows biologists to select between a hypothes...

Why don't hormones affect all cells they contact? Hormones can only affect cells that display receptors that are specific to them What is a target cell? Are the cells that display the specific receptor What are the 2 major classes of hormones (endocrine, not paracrine)? Where Peptide and steroid hormone What is a peptide hormone and where can it be found? Proteins (Polar, hydrophilic, lipophobic). Bind to cell surface receptor (on the cell surface, duh) and require 2nd Messengers inside the ...

aqueous - Of or containing water. typically as a solvent or medium Biological organization- increasing levels comes greater complexity. - Chemical - lowest levelatoms, molecules, proteins. organelles, cells. Organelles Tissue level- collection of similar cells associated with specific function. Organ level-differentiation cells (different) associate with different organs.- digestive system-cells break down gastric juices, also generate mucus. Organisms- Individual living things. Populatio...

Characteristics of Life Answer> Living things: -are organized -need energy and materials -maintain homeostasis -respond to stimuli (changes in environment) -reproduce and grow -have adaptations matter Answer> Anything that has mass and takes up space element Answer> A substance that cannot be broken down into substances with different properties atomic number Answer> =number of protons atomic mass Answer> =protons (which are = to electrons) + neutrons mass number...

Feedback mechanisms Answer> Negative feedback=Stimulus invoking a response and the response inhibiting stimulus. Positive feedback=the stimulus invoking a response and the response providing a stimulus. IE. platelets increase, cells dividing. Kingdoms Answer> Bacteria, Archaea bacteria, (both have organisms that are unicellularcomprised of prokaryotic cells-no nucleus). Archaea bacteria - exist extreme (high pH, low pH-Dead Sea). Protista (Eukaryotic cells-membrane bound nucleus)...
