I believe the term for an observable trait of an organism would be called or noted as the organism's phenotype.
Answer:
Domesticating plants and animals
Fear of snakes and spiders
Social roles and cooperation
Explanation:
The reason that we inherited these traits from our ancestors is that they confer an advantage in the environment in which we live. This process occurred through natural selection pressures that power evolution. Individuals that bore these traits had higher chances of reaching reproductive age and passing down their genes. Individuals without these traits died sooner hence their genes reduced with every generation.
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Answer:
none of the above
Explanation:
input would be carbon dioxide and output would be oxygen
Answer:
LiquidsEdit
Because the particles can move, liquids don't have a definite shape, and they can flow. Because the particles are still packed close together, liquids can't easily be compressed and keep the same volume.
