Answer:
1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
2. 170 pm is the radius of a Carbon Atom.
3. The vast majority of the mass of an atom is concentrated in its nucleus
4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.
rocks can become soil in multiple different ways one could be primary succession which means some algae or moss grows onto rocks with out soil then they slowly gain moisture which attracts some other plants like flowers which then breaks down the rock into smaller things then grasses come in and turns it into soil.
Answer:
<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.
<u>Sensory neurons </u>move information towards the central nervous system for processing.
<u>Interneurons </u>carry information from one type of neuron to another.
Explanation:
- Neurons are basic structural and functional units of Nervous system.
- Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
- Neurons can be classified on the basis of their structure and function.
- On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
- On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
Golgi bodies/ golgi apparatus/ golgi complex are the diff. names
Answer:
When the diaphragm contracts (it's a large flat muscle), it pulls the lungs down this causing expansion which eventually lead to inhalation of air. If it's injured, then that will be affected.
