Answer:

The Geological Time Scale

Explanation:

The Geological Time Scale is the framework in which the history of the Earth is inscribed. It combines a numerical scale that uses the million years as a unit (chronometric scale) and a scale that is expressed in relative time units (chronostratigraphic scale).

The chronometric scale is based on the measurement of certain physical properties of rocks, generally the relationship between the content of stable and unstable isotopes of the same element.

Nucleic acids are important information storage molecules present in virtually every cell. Which processes is carried out by a c
emmasim [6.3K]

Answer:

Transcription

Explanation:

The DNA is stored in the nucleus of the cell. The DNA has the sequence information of every gene. This means that depending on the DNA sequence, we are going to have a particular protein. The transcription is a process within the cell in which an enzyme called polymerase enters the nucleus and transcribes the DNA into another molecule, RNA. Let's say that this process makes another "copy" of the nucleic acid sequence, but now the RNA is able to get out of the nucleus carrying genetic information into the cytoplasm. In the cytoplasm, the RNA is translated into protein. During the translation, a ribosome "reads" the RNA and builds the protein depending on the nucleic acid sequence. To sum up, we can say that the transcription is the first process involved in accessing the information from the DNA.

vodka [1.7K]

Answer:

it is a failure of tolerance (self-tolerance) and specificity (recognition)

Explanation:

Type 1 diabetes is a chronic disease caused by the selective destruction of β cells that are involved in the production of insulin in the pancreas. Type 1 diabetes can be classified into two types: Type 1A diabetes (the immune form of the disease) and Type 1B diabetes (the non-immune form of the disease). Type 1A diabetes is considered an autoimmune disorder where immune responses against pathogens suffer a failure of tolerance to antigens in the β-cells of the pancreatic islets. Thus, Type 1A diabetes is characterized by the process of recognition of β-cell antigens (autoantigens) by the immune system. This disease is often caused by genetic factors associated with mutations in the human leukocyte antigen (HLA) class II region located on chromosome 6.

Prokaryotes can exchange genes with each other. True or False.​
makvit [3.9K]

Given Question:

Can prokaryotes exchange genes with each other?

Answer: <u>True</u>

Explanation:

By the process of conjugation, their DNA is <u>transferred</u> from one prokaryote to another by means of a pilus, which brings the organisms into contact with one another. The DNA transferred can be in the form of a plasmid or as a hybrid, containing both plasmid and chromosomal DNA.

How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is need
Tasya [4]

Answer: More than 1

Explanation:

A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.

Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.
