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.
They are sex cells, also known as Gametes
The correct answer is: C) secreting releasing and inhibiting factors into a tiny portal system.
Hypothalamus is part of the brain that consists of many nuclei and has the function to connect the nervous system to the endocrine system via the pituitary gland. Hypothalamus is linked with the anterior pituitary via hypothalamic–adenohypophyseal axis. Releasing hormones or factors produced in hypothalamic nuclei are first released from the prolongation of the hypothalamus and then into a tiny portal system called hypophyseal portal system. This system of blood vessels transports hormones to the anterior pituitary where they act on the secretion of adenohypophyseal hormones.
Answer:
C. genes
Explanation:
Genes are basic physical & functional unit of heredity. Genes are made up of DNA or we can say that they are segments of DNA which have instructions to synthesize bio molecules known as proteins and these protein molecules are further responsible for characteristics of an organism. Genes are located at a specific location in our chromosomes and the location is known as locus. Almost all the characteristics which an organism has depend upon the kind of information they have in their genes.
During developmental stages, how an organism will develop totally depends upon what kind of proteins are being synthesized at that time and as already explained, protein synthesis totally depends upon type of genes present in the organisms.
Answer:
Most people give credit to Benjamin Franklin for discovering electricity. ... In 1752, Franklin conducted his famous kite experiment. In order to show that lightning was electricity, he flew a kite during a thunderstorm. He tied a metal key to the kite string to conduct the electricity.
