Why is bacteria placed in the kingdom prokaryotes

Biology
1 answer:
sukhopar [10]3 years ago
7 0
Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.

Hope this helps! :)

A male giraffe has 31 chromosomes in each of its sex cells. How many would be present in its body cells?
svp [43]

Answer:

62 chromosomes.

Explanation:

Sex cells are formed undergoing meiosis, which means that they contain a haploid number of chromosomes. (Half the number that somatic/body cells contain). 31 is half of 62, which means that the diploid number of chromosomes in the body cells of a giraffe would be 62.

Do research about new hypothesis that has replaced an older explanation of something in the natural world
Gre4nikov [31]
I believe that what is meant with the phrase "older explanation" is none other that superstition. Therefore, I will give you one superstitious belief which is now explained by science.

In Southeast Asia, people used to believe that St. Elmo's fire appears in remote areas because a bloody battle occured in that place leaving disembodied souls of the dead wandering there in the night and even in sunshine!

For generations, many people believed that this is a fact and some even say that these apparitions are diabolical or demonic in nature. So often, caution is advised to people whenever a ball of fire appears out in the open. 

However, recent breakthroughs in the 21st century helped scientists to explain this mysterious phenomena. They found out that St. Elmo's fire is actually plasma, nothing special. Now, plasma is considered one of the states of matter! But mind you, it still does not explain why St. Elmo's fire seems to have a mind of its own!

1<em>. Removing oxygen:</em> The removal of oxygen from food preserves the food by avoiding the oxidation of food that leads to spoilage.Cover the food or vegetable tightly in air tight container to avoid oxygen reaching the cut cells which will cause  spoilage of food.The fruits and vegetables should immediately be boiled or cooked to prevent oxidation.

2. <em>Removing moisture: </em>The removal of excess water from vegetables and fruits helps in preservation of food. The bacterial growth that spoils the food grows in moist environment hence reducing the moisture content will preserve food.

<em>3. Killing spoilage organism: </em>The ultraviolet light and infrared light are used to kill the organisms causing spoilage of food. Flash technique is also used for preserving food from microorganism.
