egoroff_w [7]

Answer:

Option number 2 is correct. When you talk together in a group during a laboratory exercise, you are engaging in classroom scientific communication.

Explanation:

Any type of communication that is made regarding science is described as a scientific communication. This kind of communication generally involves talks about research, recent advances in any scientific topics or techniques, observations that one might have made on a particular science topic, asking another person about any science-related topic or techniques, etc.

If a scientist talks about any science topic to the public, then it would be a public scientific communication. A scientific communication made among scientists would be termed as professional scientific communication. Any science based communication that is made and kept private would be termed as private scientific communication.

Hence, option 2 is correct. A science based communication between students in a lab would be classroom scientific communication.

Which statement is true of DNA polymerase?
Snezhnost [94]

Answer:

b) DNA polymerase can synthesize DNA in the 5' to 3' direction

DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.

hope it helps btw i did this test and i got it correct

Phosphorus is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A geneticist grows some E. c
Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.

What is a possible long-term consequence of groundwater overdraft?
Travka [436]

The correct answer is B. Unproductive wells.

The possible long-term consequences of groundwater overdraft is the unproductive wells.

Groundwater overdraft is known to occur when the ground water which is used exceeds the amount which is in the aquifer.

Groundwater results in reduced in supply of water reason being groundwater pumping costs, groundwater contamination, aquifer depletion or cost of well deepening.
