Which of the following is a problem that could result from poor monitoring of free range grazing?

The increased use of antibiotics
The additional exposure of soil layers
The prevention of invasive plant species
The higher rates of mental illnesses in animals

Answers

Answer:

The additional exposure of soil layers.

Explanation:

Antibiotics are administered by humans, so less contact with humans won't cause an increased use of antibiotics. The prevention of invasive plant species is not a problem, nor would it be caused by improper management of free range animals. Mental Illness in animals is usually caused by being put in small enclosure or living in poor conditions, not by being allowed free range. Therefore, the answer is the additional exposure of soil layers, since excessive grazing can decimate plant and soil layers.

Question 1: One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic information flows between those types of molecules. Include the results of the processes of transcription and translation? ( Will Mark Brainliest if answered correctly. Do Not Repost Someone Else's Answer that is already on Brainly or any other websites please). ​

Answers

Answer:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

Answer:

DNA is the code that stores all our genetic information. When making a protein, DNA has to go through transcription and then translation. In transcription, an the genetic code of DNA is copied to mRNA, with the aid of an RNA polymerase protein which attaches single RNA units to the mRNA strand as the RNA polymerase moves on the DNA. Note that instead the letter T, RNA contains U. This occurs in the nucleus. The mRNA travels to the cytoplasm to a ribosome. The RNA also trims itself, removing parts that it does not need, and keeping parts for translation. The ribsomes use tRNA attached to amino acids to assemble the protein chain and translate the mRNA into proteins. As the amino acid chain, or polypeptide forms, a protein comes to be. However, there may be mutations, resulting from translation or transcription and sometimes these mutations may cause harmful affects.
