Answer:
DNA
It can contain the purine adenine
This contains the pyrimidine thymine
The sugars are connected with a 3'-5' phosphodiester link.
It contains equal amounts of guanine and cytosine. The percentage of A-T ,C-G are the same in DNA,,they are linked by hydrogen bonds.But varies in RNA.
Explanation:
.RNA
It can contain the purine adenine.
It can contain the pyrimidine uracil
This contains the sugar ribose. This is a 5C sugar with one oxygen atom deficient.The forms the lever for holding the bases and phosphate group
The sugars are connected with a 3'-5' phosphodiester link.This is the backbone of both DNA and RNA.It is formed between the sugars and the phosphate groups in both DNA and RNA.
None is made of base composition, the %T = %G. This is wrong because purines must pair with pyrimidine,but not two purines or pyrimidine pairing as shown,
Bases are attached to sugars in an alpha N-glycosides linkage.This is wrong the beta N-glycisidic bonds are the linkages

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.
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.
which of the following would differ if you compared the same reaction taking place with and without an enzyme
a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.

During cellular movement which filaments will be the ones that are responsible for attaching and pulling the other filaments along?
Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments

What is a retrovirus?A kind of RNA virus known as a retrovirus copies its genome into the DNA of the host cell it invades. HIV is a prime example of a retrovirus.
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. A person who has acute retroviral syndrome may no longer have any symptoms, yet they are nonetheless HIV-positive and remain contagious.

Professor George Palade’s elegant experiment to follow protein synthesis and trafficking, published nearly 60 years ago, provided us with a great deal of information and has been used as a tool by several investigators. If you had access to all the reagents needed to repeat the in vitro experiment, describe what you would need to do to see the progression of newly synthesized proteins and their transport in the cell.
Answer:
The interpretation including its particular topic is demonstrated in the following portion on the interpretation.
Explanation:
After experiments with Guinea Pigs, Palade transitioned to anything in vitro research in which sections of pancreatic tissue had all been subjected to a pulsed radioactive lysine for something like a shorter amount of time. The radiation leucine pulse must have been subsequently adopted with nonradioactive leucine, as well as the pieces have been fixed but instead analyzed besides electron microscopy as well as transmission line during some different points in time.Effects from either the radioactive elements with leucine throughout the reflective coating surrounding the tissue fragments formed autoradiographic particles.Such granules eventually passed forward towards the Golgi throughout corresponding different points in time, as well as subsequently towards the cell membranes, whereby they seemed equipped for induction as established zymogen granulates.Which type of gene is only expressed if there are two genes of that type? (1 point)
O recessive gene

Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs
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.

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.
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
