Two chromosomes cross their genetics to create variation within the daughter cells.
Enzymes are biological catalysts. ... Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate.on:
Sperm is created in the testicles
1) Colonial organisms require large areas with resources to sustain the entire colony, just as colonial people do. They are unable to grow in places that are sufficient to sustain a small number of organisms and if their population becomes to large, the colony collapses on itself. This is all visible in people as well.
2) Colonial organisms have greater safety due to their large numbers; however, unlike individual organisms, they are unable to sustain themselves with a smaller number of resources and migrating from one area to another is also more difficult for them.
3) A multicellular organism is more mobile and able to perform more functions in a better manner; however, this also leads to greater energy requirements than that of a single celled organism.<span />
