By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. This is why scientists cannot be certain about how life began.
"The ability of an organism to react to an environmental input with a change in form, state, movement, or rate of activity" is a definition of Phenotypic Plasticity.
<u>Explanation:</u>
The tendency of one genotype when opened to different conditions, to create more than single phenotype is called as "Phenotypic plasticity".It's the secret to studying human behaviour.
It's the key to human conduct study by laying the foundation to take into consideration the concept that the similar genome and the similar neural architecture will lead to human cultural diversity. For plants whose sessile existence needs them to survive with environmental conditions, this capacity is especially important.
Answer:
The correct answer is bronchioles.
The only mutations<span> that matter to large-scale evolution are those that can be </span>passed on<span> to </span>offspring<span>. These occur in reproductive cells like eggs and sperm and are called germ line </span>mutations<span>. A single germ line </span>mutation<span> can have a range of effects: No change occurs in phenotype.</span>
