It is not true that we can bring them back to life, the real thing is that the importance of fossils allows us to perfectly reconstruct the Form of Living Beings that inhabited our planet in past times, not only dinosaurs, but all those whose Remains or Depositions were covered by sediments or sedimentary rocks for a certain period of time, allowing the conservation of its shape and without too many alterations in the composition. This process occurs in a variable time interval, being also a rather rare phenomenon to be found due to that the Living Beings tend to a rapid and progressive decomposition after their death, being studied, as well as the fossils themselves, by the science called Paleontology, which in turn derives from Paleobiology (analysis of fossilized organisms) while that on the other hand we have Taphonomy (study the different stages of fossilization) in addition to Biochronology ( time in which fossilized beings lived)

To be able to consider a Living Being Remainder within the framework of what fossils are, it must first have been given a Physicochemical Phenomenon that allows specifically modifying its initial conditions, being this known as Fossilization, in which transformations are made to the Chemical Composition of the deposits, as well as variable alterations in their Physical Structure, but without profoundly modifying or altering the "design" of these depositions.

There are different regions that have a high wealth of fossils, having in Spain its location in the area of Las Hoyas and Atapuerca, where we have a large variety of Iberomesornis and on the other hand Hominid Fossils, respectively, these remains being taken to the Museums of Natural Sciences that we recommend visiting, being of great scientific and visual appeal.

What are the names of the sugars that form the main part of their nucleotides

Monica [59]

Explanation:

Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.

Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine.

Which type of drug-induced hormonal imbalance is likely to be observed in the client undergoing treatment with demeclocycline?

julsineya [31]

Answer:

Option:(D)- Cushing's syndrome.

"The disorder is formed inside the body due to having a higher level of cortisol hormones in the blood."

Explanation:

Drug Induced hormonal imbalance:

Exogenous Cushing's syndrome is mainly caused by the intake of a man made synthetic drug named as glucocorticoid medicines. As the drug causes the imbalance in the level of hormone cortisol inside the blood plasma, which lead us to having severe case of having more cortisol produced by the adrenal glands.

guajiro [1.7K]

Answer: Promoter

Explanation:

Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called RNA polymerases which perform this process of transcription. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.

A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is and contains the information needed to activate or deactivate the gene it regulates. The promoter has a binding site for the RNA polymerase enzyme in charge of mRNA synthesis and when it recognizes this site, transcription begins.
