Answer:
Ocean acidification: Ocean acidification refers to the decrease in the pH of ocean water.
The pH of ocean water decreases due to the increased in the carbondioxode emissions in the atmosphere because of the burning of fuels. This carbondioxode is dissolved in the ocean water and forms carbonic acid. This carbonic acid is responsible for increasing the pH of ocean water. In one and half century, there is 30% increase occurs in the acidity of ocean water.
Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as <em>haploid or diploid</em>, instead of 1n for one copy and 2n for two copies.
The <u>haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms</u> while <u>the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms. </u>
So, in other words: n = haploid and 2n - diploid.
I would say the first one
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.
A cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialized to perform a particular function in multicellular organisms (e.g. plants and animals).
