<span>Since the polonium atom has 84 electrons, it also has 84 protons. The protons have a positive charge (+1), and are in the nuclueus with the neutrons (no charge). The electrons (charge =-1) are NOT in the nucleus, but surround it. Thus, the total charge of the polonium nucleus is +84</span>
Answer:
Option C, anthrax bacteria
Explanation:
All options i.e amoeba, paramecium and aloe vera plant have eukaryotic cell which have well defined nucleus and layered organelles.
A prokaryotic cell lacks well defined nucleus and also do not have some essential cell organelles. Along with this the cell organelles and nucleus do not have envelope or outer layer.
Only bacteria and archae have prokaryotic cells.
Hence, option C is correct
Neuron : the nerve cells that transfer information within the body.
Neurons can be placed into three groups, based on their location and function.<span>Sensory neurons, interneurons, motor neurons.
</span>sensory neuron :<span>Transmit information from a sense receptor to the brain or spinal cord
</span>
interneuron:<span>Integrate information within brain or spinal cord; connect sensory and motor neurons; located entirely within the CNS
</span>motor neuron:<span>Transmit information from the brain or spinal cord to a muscle or gland; Cause muscle contraction or gland secretion</span>
C. Mitosis: mitotic division produce 2 genetically identical cells, so it’s not a source of genetic variation.
To be a member of the Kingdom Animalia you would have ALL but one of these characteristics. What is not required to be classified as an animal? C. Can move/motile.
