It may have to do with more olden stereotypes, where women were seen to be caretakers of the family, while the male went out to work and earn for them. Many jobs back then were dependent on strength, so as long as men fulfilled their role of earning money (through labor) their looks were seen as little importance. Let me elaborate. If a man could care for his family, he was seen as admirable, or at least acceptable to society. If he couldn't earn, then he was deemed worthless. So a man's honor depended on how his strength was. In this sense, looks didn't really contribute to a man's place in society. Women, on the other hand, were the face of the family. Men would show them off to friends, so if women weren't decently attractive, then it wouldn't be very good for the male. Other than housework, the woman's job is to literally sit still and look pretty; thus the reason behind corsets, bonnets, petticoats and so on. You won't see society asking men to wear such complicated things, because their main job is to work. It would be unsuitable for a blacksmith to be wearing tight suits while hammering, no? I hope this gave you some general insight.
Anaphase is the answer to this question
you can remember because anaphase is where the chromosomes are torn apart to opposite ends of the cel
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.
The answer while be true because it's around the same rate.
