Bubonic plague is caused by a bacillus form of bacterium called Yersina pestis. The bacterium found mainly in rodents and their fleas. This bacteria transmitted through the bite of infected fleas and rodents.

In various parts of the world this plague bacterium still exists as reported in 2003 in Africa killing 180 people. The last reported serious outbreak of this plague was in 2006 in Congo, when at least 50 people died. In recent years, the United States, China, India, Vietnam, and Mongolia have confirmed human plague cases.

Good sanitation, rodents and pest control can help in preventing plague outbreaks. Administering of correct antibiotics to the patients can control deaths.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e
cricket20 [7]

Answer:

  • The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
  • According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
  • After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

During respiration, a seed metabolizes sugars. what is the source of the sugar metabolized by the seed?
pashok25 [27]

The source of the sugar metabolized by the seed is photosynthesis.  

The procedure used by plants to transform light energy into a chemical form of energy is known as photosynthesis. The chemical energy can afterward be discharged to fuel the plants to perform their activities.  

During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates). However, the prime component generated in the procedure is glucose (sugar) that is the molecule, which generates energy to mediate the activities of the cell.

Is this mRNA or rna need help please need the answer in a hurry
Vlad [161]

It is mRNA because RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. ... During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.
