Answer:
ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting
R = Vesicle velocity / step size
Explanation:
The rate of ATP hydrolyzation can be explained by relating ΔG ( Gibbs free energy) and Q using this equation : ΔrGo + RT ln(Q). where ΔrGo = standard Gibbs energy change.
while ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting
Calculating R

A 36 years old female came to see the doctor with the complaint of amenorrhea (absence of menstrual period) for past three months. She is worried if she is pregnant although she never missed her Contraceptive Pills. She recently noticed some milky discharge from her left breast and abnormal facial hairs. She also said that her period was irregular and less in amount for past one year. She also gained 15 pounds during last year but denies any cold intolerance, dry skin, depression, fatigue or hot flushes.
Her menarche was at 14 and she had regular 21 days cycle till last year when it became irregular and gradually scanty.
Her LMP (last menstrual period) was 3 months back.
She has a 10 years old healthy child (normal vaginal delivery). She has regular Pap test, last test was done 10 months ago which was normal.
Her mother had menopause at age 55.
Her vitals were normal.
Her pregnancy test was done at the office which was Negative.
The doctor reassured and discussed hormonal imbalances with her. She recommended her urine and blood tests for hormone levels and pelvic ultrasound to check her reproductive organs. The doctor advised her to come back with all the test result
1. After reading given case, what will be the most likely diagnosis of this patient?
2. Normal woman does not show and breast discharge, what could be the reason in this patient for breast discharge?
Help me answer to your best of ability
Answer:
The correct answer is -
1. galactorrhea or prolactinoma
2. hormonal imbalance (prolactin imbalance)
Explanation:
The given symptoms experienced by the patient are the absence of menstrual cycles, an increase in weight, some milky discharge from her left breast, and abnormal facial hairs. The pregnancy tests show she is not pregnant and she also does not experience cold intolerance, dry skin, depression, fatigue or hot flushes.
All these suggest that there is a hormonal imbalance in her and due to producing a white substance from the breast it can get that there is too much production of prolactin, which suppresses the effect of estrogen, which is producing by the pituitary gland.
Galactorrhea or prolactinoma are two disorders that affect the production of prolactin that cause milky discharge, it can be caused by overuse of contraceptives or underlying conditions.
What is the role of pitutary gland in puberity
Answer:
Puberty has begun. The trigger for puberty in both boys and girls is the production of 'gonadotrophin releasing hormone' (GnRH) from a part of the brain called the hypothalamus. This hormone stimulates the pituitary gland to release two hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
Explanation:
Please Mark me brainliest
Answer:
the gland produce hormones that help to regulate growth and body functions.
The body regulates the amount of hormones are released by using feedback loops. A __ feedback loop increases the response whereas a __ feedback loop decreases the response.
Positive feedback loop increases the response whereas a negative feedback loop decreases the response.
What is positive feedback?Positive feedback is the amplification of a body's response to a stimulus. For example, in childbirth, when the head of the fetus pushes up against the cervix (1) it stimulates a nerve impulse from the cervix to the brain (2).
A feedback mechanism resulting in the inhibition or the slowing down of a process.
Examples of processes that utilise negative feedback loops include homeostatic systems, such as thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels), blood sugar regulation (insulin lowers blood glucose when levels are high ,glucagon raises blood glucose when levels are low).

Answer: All of the above.
Explanation:
The liver is simply the largest solid organ in the body and it can be found below the rib cage in the upper abdomen by the right. It's function is to maintain the blood sugar, regulate blood clotting and remove toxins from the blood.
It should be noted that the liver develops as a ventral outgrowth of the embryonic foregut. It also helps in the incorporation of both the endodermal and the mesodermal components. Furthermore, it's developed in the ventral mesentery and is connected to the stomach by the lesser omentum.
Therefore, all of the above options are correct.
During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?
Answer:
During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol
Explanation:
During the conversion of glucose to pyruvate, NAD+ is converted into NADH.
What is alcoholic fermentation?Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.
The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.
Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

La actividad de agua (aw) es la cantidad de agua libre en el alimento, es decir, el agua disponible para el crecimiento de microorganismos y para que se puedan llevar a cabo diferentes reacciones químicas. Tiene un valor máximo de 1 y un valor mínimo de 0. Cuanto menor sea este valor, mejor se conservará el producto. La actividad de agua está relacionada con la textura de los alimentos: a una mayor actividad, la textura es mucho más jugosa y tierna; sin embargo, el producto se altera de forma más fácil y se debe tener más cuidado.A medida que la actividad de agua disminuye, la textura se endurece y el producto se seca más rápido. Por el contrario, los alimentos cuya actividad de agua es baja por naturaleza son más crujientes y se rompen con facilidad. En este caso, si la actividad de agua aumenta, se reblandecen y dan lugar a productos poco atractivos. En ambos casos, el parámetro de la actividad de agua del alimento es un factor determinante para la seguridad del mismo y permite determinar su capacidad de conservación junto con la capacidad de propagación de los microorganismos.Agua y microorganismosControlar la actividad de agua en alimentos es sinónimo de alargar su vida útilCuanto menor es la actividad de agua de un alimento, mayor es su vida útil.

At which location is contact metamorphism least likely to occur
1. divergent boundary
2. convergent boundary
3 .transform boundary
Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.
-------------------------------------
Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.
Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.
It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.
It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.
I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.
II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.

Direct counts of cells in liquid samples can be performed using a Petroff-Hausser counting chamber. Research this method and describe how it compares to the viable plate count method of determining the number of CFU in a sample.
The viable plate count is the most commonly used method to estimate the number of viable cells in a sample; while the Petroff-Hausser counting chamber is a direct microscopic count method generally used for counting bacteria and sperm cells.
The Petroff-Hausser counter is a counting chamber used to count microorganisms and cells (e.g., bacteria and spermatic cells) under the microscope.
The Petroff-Hausser counter chamber is divided into 25 large squares which are in turn divided by double lines. Moreover, within each large square, there also are 16 small squares divided by single lines.
Petroff-Hausser counting chambers are often used to directly determine the number of bacteria in a culture or liquid medium. Petroff-Hausser counting chambers are used to count the number of cells in a given volume of culture liquid by observing 10 to 20 microscope fields.
The viable plate count, also known as simply plate count, is the most commonly used procedure to estimate the number of viable cells in a sample.
The viable plate count method consists in obtaining serial dilutions of a sample having viable microorganisms/cells which are plated onto a growth medium.
This method (viable plate count) can be used to determine the number of actively dividing cells.

Antimicrobial susceptibility testing was performed to screen a novel compound. The MIC was found to be 10ng/mL. Use the following data to determine the percent recovery for each treatment group. What is the MBC and would you describe the antimicrobial tested as static or cidal?
Novel compound concentration CFU/mL Present Recovery
0ng mL 3.4 x 10^5
10ng/mL 2.4 x 10^5
20ng/mL 6.4 x 10^4
40ng/mL 1.4 x 10^4
80n mL 4.4 x 10^3
160n mL 0
Answer:
a) Percent recovery
100%, 70.58%, 4.11%, 1.29% , 0%
b) MBC = 160 ng mL
c) Static
Explanation:
A) Calculate the percent recovery for each group
i) for 0ng mL
( 3.4*10^5 / 3.4*10^5 ) * 100 = 100%
ii) for 10ng mL
( (2.4 * 10^5) / (3.4 * 10^5) ) * 100 = 70.58%
iii) for 20ng mL
( ( 6.4 * 10^5 ) / ( 3.4 * 10^5 ) ) * 100 = Nil
iv) for 40 ng mL
( ( 1.4 * 10^4 ) / ( 3.4 * 10^5 ) ) * 100 = 4.11 %
v) for 80 ng mL
( ( 4.4 * 10^3 ) / ( 3.4 * 10^5 ) ) * 100 = 1.29%
vi) for 160 n mL
percentage recovery = 0%
B) what is the MBC
The value of MBC = 160 n mL because at this concentration CFU/mL = 0
c) determine if the antimicrobial tested is static or cidal
condition : If, the ratio of MBC : MIC is ≤4 then novel compound is Cidal
MBC / MIC = 160ng / 10ng = 16 : 1
hence we can conclude that the antimicrobial tested is STATIC

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms
Answer:
Protozoa
Explanation:
The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.
Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.
Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.
Hence, the case of Mr. L would be that of protozoa.
Many anti-evolutionists believe that since science doesn't have answers for all questions; scientific conclusions are not necessarily correct. This attitude reflects a failure to understand the nature of science. What is the general nature of scientific thinking? In what way is science "self correcting"?
Answer:
In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions
Explanation:
A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.
