Answer:
tRNA.
Explanation:
RNA molecule is made from the template DNA by the process of transcription. Three main different types of RNA molecule are rRNA, mRNA and tRNA.
tRNA or transfer RNA is an one of the most important RNA molecule. tRNA molecule contains the anticodon that are complementary to the codon of the RNA molecule. tRNA specifies for a particular amino acid.
Thus, the correct answer is option (C).
Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.
Answer:
Simple clothing, living in farming communities and using horse- driven vehicles best describes Amish culture.
Explanation:
The simple clothing concept of Amish culture shows their modesty. The women wear long and simple dresses that goes all the way down to their knees and they also cover their hair. They believe wearing simple dress is a way of keeping their hearts pure.
Amish people use buggy or horse driven vehicles and not cars because they believe that the innovation in technology has the potential to bring assimilation into the surrounding society.
They mostly live in farming communities which are located in Indiana, Pennsylvania, Ohio, Central American and even in Canada.
Answer:
In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.
Explanation:
During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.
In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.
