What was the evidence for bodies much smaller than atoms

Answers

Answer 1

Answer:

Explanation:

The scientist, J. J Thomson interpreted the deflection of the rays by electrically charged plates and magnets as evidence of “bodies much smaller than atoms” (electrons) that he calculated as having a very large value for the charge-to-mass ratio. That is, The masses of their bodies (electrons) was much smaller than the atoms but they had a very large charge to mass ratio.

He then proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus in order to include the electron in the atomic model.

What usually accompanies a cold spell in Minnesota?O A. The polar jet stream moves south.
O B. The polar jet stream moves north.
O C. The horse latitudes moves north.
O D. The doldrums moves south.

Answers

The polar jet stream moves south is accompanies a cold spell in Minnesota. Therefore, option (A) is correct.

What do you mean by polar jet stream?

Polar jet stream is a belt of strong upper-level breezes that sits on the polar front. The winds generally move in a westerly direction in midlatitudes and are strongest at the tropopause, the upper boundary of the troposphere.

The convergence of cold air masses coming down from the Arctic and warm air coming up from the tropics creates the jet. Profound box and soak edges arise as the denser virus air sinks and redirects warm air locales north, giving the fly stream its wavy appearance.

The northern polar jet stream is the most important jet stream for aviation and weather forecasting on Earth because it is much stronger and lower in altitude than the subtropical jet streams.

Which statement best describes the relationship between proteins and nucleic acids? Proteins read the instructions that are contained in nucleic acids. Nucleic acids synthesize the amino acids for protein construction. Nucleic acids provide the blueprint for the construction of proteins. Proteins are composed of nucleic acids..

Answers

The nucleic acids provide blueprints for the construction of proteins. The mRNA (messenger RNA) takes the genetic info of the proteins from the DNA ( Deoxyribonucleic acid) and it give it to the ribosome (which produces proteins) so the ribosome produces protein according to the 'blueprints' that came from the DNA

Nucleic acids provide the blueprint for the construction of proteins, the third statement best describe the relationship between proteins and nucleic acids.

The primary information-carrying molecules in the cell are Nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main forms of nucleic acids. DNA is the genetic substance of all free-living creatures and the majority of viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays a crucial part in activities such as proteinsynthesis.

The mRNA (messenger RNA) receives the genetic information of the proteins from the DNA (Deoxyribonucleic acid) and gives it to the ribosome (which generates proteins), so that the ribosome may produce proteins based on the 'blueprints' that came from the DNA.

Thus, the third statement best describes the relationship between proteins and nucleic acids.

Jordan is a 14 year old middle school student, weighing 275 pounds and is 5’6” tall. Over the past 2 years, he has gained 60 pounds, as he has begun to withdraw from social activities, and avoid other students, due to bullying from others his age about his weight/appearance. Lately, Jordan has been missing a great deal of school too, particularly on the days he has gym. Jordan’s parents are both average in height and weight, and Jordan’s mother says that he just takes after his grandfather William, who “was a husky man, and died of a sudden heart attack at the age of 44”. She says “We just have fat genes in the family; you can’t do anything about that”! He has been told he had “no willpower, or is weak, or that he needed to change his lifestyle, eat less and exercise more.” Jordan says “I go for a couple days without eating, but then I get so hungry that I could eat the couch”! You are the school nurse doing height and weight assessments on the middle school group this year. How would you assess and advise Jordan?
