Explain the process of how air flows through the Respiratory System? In three sentences.

Answers

Answer:

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

Investigator Campbell is in charge of the forensics lab. One of the analysts in the lab ended up with contaminated evidence from the scene of an explosion. Looking through their work area, she sees they have a very small table next to a sink with small nylon bags stored in tight rows at room temperature. What would she advise the analyst to change about their evidence system? The evidence needs to be refrigerated quickly between analyses. The evidence can't be stored in nylon bags at all. The bags can't be kept so close together. They can’t be near the sink—it’s too humid.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.

What is the relationship among the parts of this system?

Answers

Answer:

The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.

Explanation:

The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.

Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.

Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.

B. Transportation of mRNA does not occur.

C. The nuclear membrane is ruptured.

D. RNA sequence is incorrect.

CLEAR ALL

Answers

Answer:

D. RNA sequence is incorrect.

Explanation:

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.

This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).

the cells produced during meiosis are?

Answers

Answer:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

8. Outline the process of metaphase, inclusive of the role of microtubules and the centromere.

Answers

Answer:

Chromosomes are positioned in the middle of the cell during metaphase.  

Explanation:

During metaphase, the centrosomes are at opposite poles or sides of the cell.  The spindle apparatus is formed and the nuclear membrane has dissolved.  The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions.  The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division.  The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart.  They are important for the cell to be able to divide.
