svlad2 [7]

Answer:

1. DNA

2. Nucleus

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific  tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

In _______ a population isolated by a geographic barrier becomes a new species as it accumulates changes by natural selection or
Mashcka [7]

Answer:

The correct answer is allopatric speciation.

Explanation:

Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.

So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.

What is the first step in the treatment process for addiction where the addiction is systematically and safely withdrawn?
solniwko [45]

Answer:

Medical Detoxification

Explanation:

Detox or detoxification is the process of safely and systematically withdrawing from a substance such as drugs or alcohol. For many, it’s an important first step in recovery, allowing the body to withdraw from potentially dangerous substances without risking hospitalization.

Many drugs have significant withdrawal symptoms once you quit using them, you tend to experiencing considerable discomfort and pain. Without proper medical attention, these withdrawal symptoms can become dangerous to your health and even become life‐threatening.

Objectives of Detoxification include

1. Evaluation‐the testing of substances in the bloodstream, their concentrations and any co‐occurring mental or physical conditions that may accompany substance abuse as well as other medical and social assessments.

2. Stabilization‐assisting patients through the withdrawal process towards a stable and substance‐ free state.

3. Fostering Entry into Treatment‐preparing clients to enter formal treatment and providing encouragement and support.
