_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

Answers

Answer 1

Complete question:

The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

TrueFalse

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

Final answer: The correct option is B,A,C,humans.

2. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla’s DNA sequence.

Final answer: The correct option is (c).

3.  These structures are known as homologies because they result from species evolving from the same common ancestor.

Explanation for correct option:

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Explanation for incorrect option:

Analogies structure are body parts that have a similar function but differ in structure.

Final answer: homologies; from the same common ancestor.

5. All vertebrate embryos have a tail and gill slits at some point during embryonic development.

Vertebrates are similar in origin and that they develop similarly, implying that they are related, have common ancestors.

Final answer: These species share a common ancestor.

5. Fossil B was found deeper in the ground than Fossil A.

Fossil A could not be older than Fossil B as it has settled for a shorter period of time, and is higher up to the surface.If the two species existed at the same time, they could be at same heights in the soil.

Final answer: Fossil B is most likely older than Fossil A.

6.This shows that the vertebrates are similar in origin and that they develop similarly, implying that they have common ancestors.

In the embryonic stages, they all possess the ventral heart, aortic arches, gills and gill slits which are exactly like those of the fish embryo. Presence of tail at some stage of development. These observations support the idea of organic evolution.This similarity of basic plan is because of shared genetic material and those genes that are still the same among organisms.

Final answer:  All vertebrates develop a backbone that protects the spinal cord.

7. Mutations have no effect on the organism because they are repaired before protein synthesis occurs.

Silent mutations lead to a change of one of the letters in the triplet code that represents a codon, but despite the single base change, the amino acid that is coded for remains unchanged or similar in biochemical properties.

Final answer: The mutated sequence still codes for the same amino acid.

8. Embryological develoment is typically studied when analyzing not-yet-born (or unhatched) animals.

Explanation for correct answer:

Embryology is a branch of science that is related to the formation, growth, and development of embryo.

Explanation for incorrect answer:

The theory of evolution is based on the idea that all species are related and changes over time.DNA sequencing refers to the technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule.

Final answer: Embryological development.

9. DNA molecules can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor.

Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related.

Final answer: DNA molecules.

10. Embryology is important to understanding a species' evolution, since some homologous structures can be seen only in embryo development.

Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor.

Final answer: Embryos go through various stages that suggest the animal’s evolutionary process.

11. A DNA analysis can help determine is the species is related to any other organism like on earth.

After isolating the DNA from its cells, specific regions are copied with a technique known as the polymerase chain reaction, or PCR. PCR produces millions of copies for each DNA segment of interest and thus permits very minute amounts of DNA to be examined.

12. Evolution is a process of gradual change that takes place over many generations.

Evolutionary biology allows us to determine not only how and why organisms have become the way they are, but also what processes are currently acting to modify or change them.It helps us to understand the development of antibiotic resistance in bacteria and other parasitic organisms.

13. The first alligator ancestors developed approx. 245 million years ago.

The main reason for the change in the body structure of alligator is due to change in environmental condition.DNA shows how related species are to other species.Fossils can be used to prove the existence of the evolution of alligators and to compare and contrast what they looked like in the past to what they look like now.

3. The human body has devised an excellent method to keep the body pH under control. a. What principle underlies the constant pH of human blood, and how does the blood achieve this

Answers


The normal blood pH for adult humans is 7.40, and this pH value is vigorously defended at normal body temperature

Acid base Homeostasis is the method by which body keeps a constant ph
pH is kept under check via different systems
1. Chemical system :bicarbonate buffer system(explained below )
Respiratory component :
2. Respiratory Component: The second line of dense is rapid consisting of the control the carbonic acid concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation. This blows off or retains carbon dioxide (and thus carbonic acid) in the blood plasma as required

3.Metabolic component : third line of defense is slow, best measured by the base excess,eand mostly depends on the renal system which can add or remove bicarbonate ions to or from the ECF.Bicarbonate ions are derived from metabolic carbon dioxide which is enzymatically converted to carbonic acid in the renal tubular cells.There, carbonic acid spontaneously dissociates into hydrogen ions and bicarbonate ions.When the pH in the ECF falls, hydrogen ions are excreted into urine, while bicarbonate ions are secreted into blood plasma, causing the plasma pH to rise.The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma.




Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system’s pH within a narrow range.

Maintaining a constant blood pH is critical to a person’s well-being. The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. Similarly, excess carbonic acid can be converted into carbon dioxide gas and exhaled through the lungs; this prevents too many free hydrogen ions from building up in the blood and dangerously reducing its pH; likewise, if too much OH– is introduced into the system, carbonic acid will combine with it to create bicarbonate, lowering the pH.
Example: Antacids, which combat excess stomach acid, are another example of buffers.
