Answer:
Stem cells are cells in the human body that have the ability to develop into many other body cell types. Stem cells are very useful for drug development, research, they aren't likely to be rejected in transplants, and are used to repair damaged or diseased cells and tissues. However, they cannot be grown for long periods of time, there are very small numbers in each tissue and cell making them very hard to find, and for certain studies they have been shown to cause cancer. To be honest, using them in research does have its pros and cons, they are very useful and easier to use in research, plus they can help repair damaged and diseased cell tissues. But at the same time they can be difficult to use correctly and properly, it can cause serious health problems if cancer doesn't take place. I think that using them in research is okay, as long as they are used correctly and properly.
Hope this helps! :)
When particles spread out it is called diffusion.
Ecology is the science that studies the interaction between living beings and the environment in which they live.
<h3>How can I help with conservation?</h3>
- Buy recycled paper avoiding the death of more trees
- Have a recycling bin for paper, plastic, metal and glass, to reduce the environmental damage in waste and for the waste to be reused
- Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
- If possible buy remanufactured cartridges, avoiding environmental impact
- Recycle old newspapers, avoiding the death of more trees.
<h3>What is the evidence for evolution?</h3>
- Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
- Molecular biology. DNA and genetic code reflect the common ancestry of life
With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.

Answer:
axon; dendrite
Explanation:
A neuron has three main parts. These are axons, dendrites, and a cell body. Synapse is the site of communication between two neurons. The first neuron of a synapse is called the presynaptic neuron (sending neuron) while the second one is called the postsynaptic neuron (receiving). The axon of the presynaptic neuron and the dendrites of the postsynaptic neuron communicate with each other at the synapse as the axon of the first neuron delivers the nerve impulse away from the cell body.
Dendrites function as the receiving or input portions of a neuron. The plasma membranes of dendrites have numerous receptor sites for binding chemical messengers from the presynaptic neuron.
