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 better sexual or asexual? Reproductive
Answer:
to reproduce sexual is better
Explanation:
i think if your asexual you don't feel attraction so you probably wont have intercourse and not reproduce whereas if your sexual you will
Answer:
tough question
Explanation: asexual is a broad broad broad spectrum some people who are ace are willing to have intercourse just wont find pleasure in it or some people are willing to have intercourse every once in a while or when they feel like it so technically ace people can reproduce just probably more likely that they wont but the question is also probably not the best because not all ace people are the same
The force of a muscle contraction is higher when the muscle is stimulated every 0.5 secs than when stimulated with the same voltage every 0.05 seconds.
a. True
b. False
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

Describe the process of action potential conduction and neurotransmission from one neuron to another, both electrically (including saltatory conduction) and chemically. 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
You put 10ul (one loopful - the loop is calibrated for this volume) of a 0.03 ug/ul pGLO solution into the DNA tube. Calculate the ug of DNA you put into the tube.
Answer:
The µg of DNA put into the tube is 0.3 µg.
Explanation:
Here in this question, we are interested in calculating the µg of DNA put into the DNA tube.
This can be calculated using a mathematical formula.
Mathematically;
Total amount of DNA in µg = concentration in µg/ µl X volume in µl

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.
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
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.

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.
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.2.

Explanation:
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.

Explanation:
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?
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.
