M - MRSHGREN - Answer movement, for all or part of the organism
R - MRSHGREN - Answer respiration, getting energy from food
S - MRSHGREN - Answer Sense, changes in the surroundings
H - MRSHGREN - Answer Homeostasis, controlling their internal environment
G - MRSHGREN - Answer growth, development
R - MRSHGREN - Answer reproduction, producing offspring
E - MRSHGREN - Answer excretion, removing waste products
N - MRSHGREN - Answer nutrition, needing of food
Test for glucose - Answer 1. Warm water bath
2. Benedict solution turns brick red
Test for Starch - Answer iodine solution turns blue or black.
Definition of enzyme - Answer Biological catalysts that control all the reaction in a cell
What happens when the active site stops the enzyme working? - Answer Denatures
What is Aerobic respiration? - Answer Respire that requires oxygen
Equation for Aerobic respiration - Answer Glucose + Oxygen = Carbon dioxide + Water +
Energy
, What is Anaerobic respiration? - Answer Respire that doesn't requires oxygen
Equation for Anaerobic respiration - Answer Glucose = Ethanol + Carbon dioxide + some
energy
Test for carbon dioxide - Answer bubbles in limewater, turns cloudy
Definition of diffusion - Answer movement of particles from an area of high concentration to
an area of lower concentration. It is caused by random movement of particles.
Definition of Osmosis - Answer Only water moves across a partially permeable membrane
from an area of high concentration to a low concentration
Definition of active transport - Answer Substances are moved against a concentration
gradient or across a selectively permeable membrane. Uses energy produced by cellular
respiration
All specialized cells in order - Answer Organelles, cells, tissues, organs, organ systems
Features of Plants - Answer - multicellular
- carry out photosynthesis
