Answer:
Cystic fibrosis is caused by a small change in the DNA sequence of one gene.
Explanation:
Cystic fibrosis is caused as a result of changes in the cystic fibrosis transmembrane conductance regulator
Answer:
<em>condensation or dehydration synthesis</em>
Explanation:
A condensation reaction can be described as a reaction in which two molecules combine to form a larger molecule. A water molecule is usually dispersed during this reaction.
For example, two amino acids join to form a protein. The bond formed between them is known as dipeptide bond.
Dehydration synthesis is also a reaction in which molecules via covalent bonds to form larger molecules. As water molecule is released during this process, this reaction is termed as dehydration synthesis.
The characteristics that would tell one that the object is abiotic, or not alive is that object responds to stimuli.
<h3>WHAT IS A LIVING THING?</h3>
A living thing is any organism that possess life as depicted by the exhibition of certain characteristics.
The characteristics of living organisms are as follows:
- Ability to reproduce i.e. make copies of itself
- Ability to respire
- Ability to respond to stimuli i.e. irritability
- Ability to increase in size i.e. growth
- Ability to excrete waste products.
According to this question, a scientist who has discovered a new object wants to find out if the object is biotic (living) or abiotic (non-living).
Therefore, the characteristics that would tell one that the object is abiotic, or not alive is that object responds to stimuli.
