What is the smallest unit that we recognize as "being alive"? - ANSWER cell Which of the following structures is only associated with eukaryotic cells? SELECT ALL THAT APPLY - ANSWER 1. Mitochondria and other organelles 2. Nucleus containing the DNA One general attribute that sets life apart from non-living matter - ANSWER Those that require the ability to pass on hereditary information -reproduction and growth -evolution Another general attribute that sets life apart from non-livi...

Explain why plasma membranes are said to have a fluid mosaic structure. - ANSWER 1. Fluid because the phospholipids are constantly moving. 2. Mosaic because the proteins are scattered throughout the membrane-like tiles in a mosaic. What effect does cholesterol have on the cell membrane? - ANSWER 1.Cholesterol molecules fit between the phospholipids and bind to the hydrophobic tails of the phospholipids. 2.Causes them to pack together more closely, restricting the movement of other molecules i...

A. albumin B. alpha and beta globulins C. gamma globulins ‐ their origin ‐ their different types and role 3.) What is the largest immunoglobulin called and what is its function? 4.) What is the most abundant immunoglobulin called and what is its function? 5.) What is the name of the immunoglobulin which is involved in an allergic reaction? 6.) When an ...

This document encapsulates the core concepts discussed in Lecture 21, focusing on organisms' gas exchange and circulatory systems. It elaborates on Fick’s Law and the Hagen-Poiseuille Equation, explaining how physical constraints influence the evolution of gas exchange organs and circulatory systems. Furthermore, it delves into the mathematical formulations of gas flux and flow rate, emphasizing the crucial role of concentration gradients and pressure differentials in gas exchange. The docume...

Summary of what you need to know for a level biology ocr a crossing membranes including topics such as diffusion (facilitated, endo and exocytosis and simple) and osmosis.

This summary page is hand written on an iPad.It is a colourful and detailed and includes diagrams and drawings to help you visualise and learn key concepts as well clearly layer out adaptations for each exchange systems. Also includes keywords and concepts of rick’s law and surface are to volume ratio!These really helped me achieve my As/A* in mocks .
