Strongest evidence points towards shared taxon
Answer:
An index fossil is also known as guide fossils or indicator fossil. They are fossils used to determine and identify geologic periods.
The main characteristics of an index fossil include :
1.It must be distinctive.
2.It must be widespread.
3. It must be abundant
4. It must be limited in geologic time.
Due to trends and studies of most fossil-bearing rocks being formed in the ocean, the major index fossils are mostly marine animal or plant organisms.
I think this is correct
1. Organelle, cells, tissues, organs, organ systems, organisms, population, communities, ecosystems and finally biosphere.
2. (Human Body) Bone cells, Fat cells, Nerve cells.
3. neuron, a collection of neurons, nervous system, brain
4. Plants don't have a liver, stomach or lungs, while animal organ systems do.
The probability of the offspring having a bent finger is 100% we can calculate this using a punnet square like one attached, where B is the dominant bent fifth finger and b is the recessive bent fifth finger, the man's genes are along the top and the woman's genes are along the side.
