Answer:
to deliver information about the physiological variable to the integrating center
Explanation:
The afferent or sensory neurons function in transmitting sensory information as action potential from the receptors to the CNS. It synapse with the inter neurons, at the spinal cord, for a bypass to the brain for mediation, The response from the brain is integrated (synapse with the efferent neuron) in the spinal cord and conducted by efferent or motor neuron to the effectors.
Resorbing or breaking down bone matrix are the responsibilities of Osteoclasts. It is a balance between bone production and bone absorption into the circulation of tissue or cells which is obligatory for remodeling and re-establishing the skeleton. Osteocytes are mature osteoblasts – a cell that produces and discharge a substance for bone formation.
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.

Explanation:
Homologous chromosomes are 2 physically different chromosomes that have the same genes but are not genetically identical. Sister chromatids are 2 copies of a single chromosome and so are genetically identical (they also are physically attached to one another).
Answer:
- Physical and chemical barriers
- non-specific innate responses
- specific adaptive responses
<u>The differences are...</u>
The first barrier is the physical and chemical barrier. It is the first line of defense when in contact with outside sources, this can be through the skin, earwax, nose-hair, etc.
The second barrier, the non-specific innate response, is after these outside sources have somehow managed to pass through the first barrier. They come into contact with cells and enzymes that help to defeat them.
The third barrier, the specific adaptive response, is the body's way of dealing with pathogens that the body has encountered before. (B cells activate)
