During cellular movement which filaments will be the ones that are responsible for attaching and pulling the other filaments along?

Answers

Answer 1

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

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.

In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

a. True
b. False

Answers

Answer:

this is true it neutralise easily

It is true that in the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

What is DNA isolation?

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellular components using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensic science, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.

A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?

Answers

Answer:

osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.  

Explanation:

Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.

The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it

from either of the parent because it's a genetic disorder. The health care

provider should teach the parent about how to prevent the effect of having

such disease such as bone fractures.

Osteogenesis imperfecta is a genetic disorder inherited by offspring from

their parent. The disease involves individuals having very  brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.

Answers

Answer:

First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout  ( light bulb may not be working )

Explanation:

The three possible hypothesis for light not to turn on immediately after one on the switch are;

First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout  ( light bulb may not be working )

We test the first hypothesis, how?

We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.

To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.

As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.

The three hypotheses we can derive from entering a dark room, turning on a

light switch,and the light not coming on include

There may be no power source at that momentThe bulb may be faultyThe switch may be faulty

A power source helps to provide energy to power up an appliance and where it is absent, the bulb won't light up.

A defect in the switch and bulb may also hinder the light from coming on as

the switch controls electric current flow while the bulb produces the light.

No change
VC (Vital capacity)
IC (Inspiratory capacity)
FRC (Functional residual capacity
TV (Tidal volume)
IRV (Inspiratory reserve volume)
ERV (Expiratory reserve volume)
RV (Residual volume)

Answers

Answer:

During intense exercise:

lung capacity increases

vital capacity increases

respiratory capacity increases

functional residual capacity increases

tidal volume increases

the inspiratory and expiratory reserve volumes decrease as does the residual volume.

Explanation:

Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.

If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.

Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.

It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage

A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.

Answers

Answer:

D) The lac operon will function normally.

Explanation:

The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.

If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.

Promotor:

It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.

How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change

Answers

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

Answers

Answer:

C. facilitates the absorption of vitamin B12.

Explanation:

The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.

The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.

Explanation:

β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.
