Answer:
C. RNA polymerases.
Explanation:
Bacteria has a primitive type of RNA polymerase while archaeal RNA ploymerase is more advanced and complex than that of bacterial. The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
Homeostasis can be defined as the state of maintenance of the constant internal conditions by the living organisms. The homeostasis is maintained by the body so that it may function properly. The homeostasis will be disturbed by the reduced intake of the food and water. Healthy intake of water and food is essential in maintaining the homeostasis of the body. The elevated or depressed blood pH along with extreme body temperatures will also disturb the homeostasis of the body making the person sick. Moreover, certain infectious organisms also alters the homeostasis of the body.
Hence, all the options are correct.
The answer is D) <span>Calculate the probability of a child having either sickle-cell anemia or cystic fibrosis if parents are each heterozygous for both.
The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. In a case when you want to calculate the possibility of a child having EITHER sickle-cell anemia OR cystic fibrosis, you will use THE ADDITION RULE.
For example, in statement B) you will not use this rule because there is no either/or, but both/and. In case, B) you would use the multiplication rule.</span>
C. ATP synthase I promise you this is right :333333
Answer: The correct answer for the fill in the blank is D) Nucleus, ribosomes.
In all eukaryotic cells, the process of transcription (formation of mRNA from DNA) takes place in the nucleus. mRNA (messenger RNA) is then transported to cytoplasm where it is translated to form proteins at the site called ribosomes.
Ribosome is a specialised membrane bound organelle that is responsible for assembly of proteins.
Thus, option D) Nucleus, ribosomes is the right answer.
