Describe the difference between selective breeding and genetic modification
tekilochka [14]

<h3>What is genetic modification?</h3>

A technique to change the characteristics of a plant, animal, or microorganism by swapping a piece of DNA from one organism to an another organism is referred to as gene modification.

Selective breeding entails selecting parents with specific characteristics to breed with in order to generate offspring with more desirable characteristics.

Individuals in selective breeding should be of a similar species. Scientists use GMOs to generate new gene combinations. Genes pair on their own through selective breeding.

What do metabolism, respiration, and digestion have in common?
Montano1993 [528]
Metabolism, respiration and digestion are all complex chemical processes involving many steps, happening in 3 dimensional space within cells. Metabolism is the breaking of bonds within food molecules (like sugar) to harness energy for cellular work; respiration involves moving oxygen and carbon dioxide gases between cells to facilitate cellular metabolism and digestion involves breaking down food macro structures into smaller units suitable for metabolism.

So the answer is D - each of the three process involve multiple chemical reactions.
