Answer;
A. A-delta fibers
A-delta fibers transmit pain that is sharp, nonchronic, and well localized.
Explanation;
-The information about touch and pain is transmitted to the spinal cord and brain by primary afferent axons - these are the nerve fibers connected to the different types of receptors in the skin, muscle and internal organs.
-The different nerve fiber groups are; A-alpha, A-beta, A-delta and C-nerve fibers.A-alpha, A-beta and A-delta nerve fibers are insulated with myelin. C-nerve fibers are unmyelinated.
-A-delta nerve fibers carry information related to pain and temperature. A-delta nerve fibers can conduct action potentials as fast as a sprinter in the Olympics.
Answer:
the factors that a cell considers when deciding whether or not to move forward through the cell cycle. These include both external cues (like molecular signals) and internal cues (like DNA damage).
Explanation:
Can be extremely corrosive
A dihybrid cross allows us to look at the pattern of inheritance of two different traits at the same time.
Answer;
5. the flipper of a dolphin and the arm of a koala
Explanation;
Homologous structures are body structures that share a common origin, the degree at which these structures resemble each other can be used to infer the closeness of evolutionary relatedness.
-A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. It's when very different animals have bones that appear very similar in form or function and seem to be related. For example; the flipper of a dolphin and the arm of a koala.
