The inferior region of the brain stem, the __________ houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.

Answers

Answer 1

Answer:

The inferior region of the brain stem, the medulla oblongota houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.

Explanation:

The medulla oblongata is the part of the brain that joins the spinal cord and forms the lower part of the brain stem. In the bulb there are ascending (sensory) and descending (motor) fascicles that communicate the spinal cord with the brain, in addition to numerous nuclei or centers (masses of gray matter) that regulate various vital functions. The medulla oblongata has the function of controlling vital and unconscious elements such as the heartbeat and blood pressure. Thus, it is responsible for maintaining the heart rate and regulating vasoconstriction. Also, it manages the control of respiratory function, maintaining it at all times.

What is the role of reverse transcriptase in DNA technologies?
A. To unzip DNA strands
B. To find mRNA
C. To produce proteins
O D. To make cDNA

Answers

Answer:

D...........................................................................

Explanation:

Reverse transcriptase may be a DNA polymerase enzyme that transcribes single-stranded RNA into DNA.

What is reverse transcriptase?

This enzyme is in a position to synthesize a double-stranded DNA into a single-strand DNA once the RNA is transcribed in 1st step.

Found in retroviruses, like the human immunodeficiency virus (HIV).

Reverse transcriptase is used to form a cDNA copy of the mRNA.

The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without introns

Thus, we can conclude that the correct option is D.

B. Bald eagles are hunted until near extinction, population recovers

Explanation:

A bottleneck effect can arise when the population of a species is drastically reduced by an occurrence. Human activities plays a major role in regard to creating a bottleneck effect in our present day. Human activities such as overhunting result into bottleneck effect. When overhunting reduces the population of a particular species, the few individuals left would have a reduced genetic variation which is not representative of the original population. The few individuals left further reproduces individuals of their kind carrying a genetic composition that is different from the original gene composition of the old population.

The case of the hunting of bald eagles until near extinction before they begin to recover is a perfect case of the bottleneck effect. Only a small proportion of the eagles original population survives. Generic variation reduces. The genetic variation in the new population of the bald eagles will be different from that of the original population.

a permanent disease process that is characterized by destruction of the alveolar walls and distention of the alveolar sacs is a type of COPD called

Answers

Answer:

Emphysema

Explanation:

Pulmonary emphysema disease progressively destroys the fibers that promote respiration, leading to a decrease in respiratory function, emphysema being a more serious complication of any bronchopulmonary obstructive inflammation. In emphysema, the walls that separate many of the alveoli are damaged and gas exchange in the lungs decreases. This disease originates when the pulmonary alveoli are progressively destroyed and difficulty in breathing becomes greater and greater. When destroyed, a larger space is created, instead of small chambers. And this affects the length of the lungs and the amount of oxygen that reaches the blood.

CUA (This one is wrong)


I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!

Answers

Answer:

CUA

Explanation:

Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.

DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)

RNA has 4 bases: AUGC  (RNA lacks the base T so A binds with U instead).

So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.

A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine)  in a sequence.

Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.

Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Proteins are responsible for the structures and functions of organisms.

What is Protein?

Large, intricate molecules classified as proteins perform an array of essential roles in the human body. They are fundamental for the structure, operation, and control of the body's tissues and organs and perform out the majority of their work inside cells.

Many thousands of amino acids, which seem to be smaller components that make up proteins, are linked together in lengthy chains to form proteins. To form a protein, 20 different kinds of amino acids can be mixed. Each protein's precise function and characteristic 3-dimensional structure are established by its amino acid sequence.

Thus, Proteins are responsible for the structures and functions of organisms.

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.

1) Give two pieces of evidence which show that this is an asexual method of reproduction.

2) Explain why all the new tubers will be genetically identical.

Answers

Answer:

See the answer below

Explanation:

Evidence that shows that the illustration is an asexual method of reproduction:

1. New tubers were produced without any signs of flowering or fertilization

2. Parent plant was produced from a vegetative part ( a tuber).

All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the  old tuber that produced the parent plant.
