Electrons are the smallest of the three particles that make up atoms.
Please correct me if I'm wrong!! I'd be happy to fix it!! :)
The
changeable nature of models is considered a limitation because when the model alters,
the answers that were achieved from the model may also transform.<span> <span>What this
means is that outcomes that’s been extracted from changeable models can be true
at a certain moment, place or situation, but the conclusions may not be
objectively true.</span></span>
Yes you can. The atomic mass measured from the proteins and neutrons in an atom, since you know he number of protons, you can subtract and be left with the number of neutrons.
<u>Answer:</u>
Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.
<u>Explanation:</u>
- One of the major difficult issue related to bird evolution is the evolution of feathers.
- Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
- Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
- Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
