Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answers
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.

Describe how a cell fires an action potential and be sure to address which structures are involved in neurotransmission. Discuss reuptake and enzymatic degradation (breakdown) in the context of the appropriate neurotransmitters.
Answers
Answer:
neurons are able to communicate through electrical impulses for example when a stimulus is detected the receptor cells transfer electrical impulses to the sensory neurons which is passed onto the relay neurons in the central nervous system and relayed to the motor neurons. the motor neurons travel with the electrical impulses which are transferred to the effectors to cause a response. However neurons travel and commu icate through synapses

By 1884, extensive hunting reduced the number of Northern elephant seals to fewer than 100. The extremely limited genetic variation in these seals is consistent with which genetic effect?
Answers
Answer:
Genetic drift, specifically the Bottleneck effect.
Explanation:
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
The bottleneck effect is a special case of genetic drift, which is most likely to affect smaller populations. In the exposed example, extensive hunting reduced the number of Northern elephant seals, reducing the number of individuals to fewer than 100. This population experienced one or many generations of very small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered, but the genetic pool might have not.
Why did the leaves rise? Will the leaf discs float faster or slower if the rate of photosynthesis is decreased? (5 points)
Answers
Answer:
Leave rise and floating depends on the production of oxygen.
Explanation:
The leaves rises due to consumption of oxygen which is produced during photosynthesis. Floating of leave occurs due to production of oxygen in the process of photosynthesis. The leaf discs float faster if the rate of photosynthesis is increases because oxygen production is also increases while the leaf discs float will be slower if the rate of photosynthesis is decreased due to low production of oxygen.

somebody help me please A cross is performed between a bird that is homo for red feathers and a bird that is homo for blue feathers. Purple offspring result due to incomplete dominance. Then, two of the purple offspring are crossed. What proportion of the offspring from the second cross will be purple? 1 in 4 2 in 4 3 in 4 4 in 4
Answers
Answer:
2 in 4
Explanation:
Let PP are the gametes of red feather bird and pp are the gamete of blue feather bird. In the first cross they both will give purple feather bird because of incomplete dominance.
Consider Pp as the allele of purple offspring for the second cross. When two of the purple offspring are crossed, it will give the proportion of 2 in 4
F2: Pp X Pp
Offspring: PP, Pp,Pp, pp
So, only two offspring, Pp is with purple feathers while PP has red and pp has blue feathers.
Hence, the correct option is 2 in 4.
The proportion of the offspring from the second cross that would be purple will be 2 in 4.
Let us assume that the red feather color is controlled by allele A and that of blue feather color is controlled by allele B.
Homzygous red feather birds will have the genotype AA
Homzygous blue feather birds will have the genotype BB
Crossing the 2 birds:
AA x BB
AB AB AB AB
Thus, the purple offspring are AB.
Crossing 2 of the purple offspring:
AB x AB
AA AB AB BB
1 AA - red
2 AB - purple
1 BB - blue
Thus, 2/4 or 1/2 or 50% of the offspring from the second cross will be purple.

The removal of sections of RNA, called introns, occur at which regulation step in eukaryotic cells? (1 point)
o mRNA life span
O post-translation
O RNA processing
ochromatin remodeling
Answers
Answer:
post-translation
Explanation:
When a eukaryotic gene is transcribed in the nucleus, the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. Instead, it's an "immature" molecule called a pre-mRNA.
The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.
Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons. This process is called splicing.
In the process of alternative splicing, different portions of an mRNA can be selected for use as exons. This allows either of two (or more) mRNA molecules to be made from one pre-mRNA.
Answer:
RNA processing
Explanation:
RNA processing. Splicing, capping, and addition of a poly-A tail to an RNA molecule can be regulated, and so can exit from the nucleus. Different mRNAs may be made from the same pre-mRNA by alternative splicing.

A virus that employs RNA as its genetic material is referred to as a retrovirus. When a cell becomes infected with a retrovirus, the retroviral RNA is converted to retroviral DNA, which is then inserted into the DNA of the host cell.
Acute retroviral syndrome symptoms, which include headache, nausea, diarrhoea, and body pains, are comparable to those of the flu and go away on their own in a few of weeks.

Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs
Answers
Answer:
The loop of henle is a part of the renal functional unit.
This handle has an ascending part and a descending part.
In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.
In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.
Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.
Explanation:
A very important fact is that urea is absorbed in the ascending henle loop.

Answers
Answer:
b. False
Explanation:
Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds
