In an experiment, a small dialysis bag is filled with a 20% salt solution. It is placed in a
beaker filled with a 40% salt solution. Assuming that water can pass through the
small pores of the dialysis bag, whereas the large salt molecules cannot, what will
happen to the size of the dialysis bag?

Answers

Answer 1

Answer:

The bag will get smaller

Explanation:

Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.

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

Answers

I say it’s 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.

Help me answer to your best of ability

Answers

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.

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?

Answers

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.

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

Answers

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.

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce ____________ against sperm cells' ____________ and render someone sterile.

Answers

Answer:

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce __auto-antibodies__ against sperm cells' __auto-antigens_ and render someone sterile.

Explanation:

Auto-antibodies are antibodies that can destroy cells from the same organism. They are mistakenly directed against organs or tissues of the same organisms, causing auto-immune diseases or affections. The autoantibodies action occurs when the organism fails in recognizing its own cells and faces them as strange elements.

Auto-antigen is the molecule produces by the body that fails in being recognized due to a break up in the tolerance mechanisms, triggering an immune response.

In the exposed example, sperm cells do not usually mix with blood. So when they do, blood cells recognize them as strange bodies and act against them. Sterility might be an effect of this auto-immune response.

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

Answers

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

c] A red flower and a yellow flower mating to produce an orange flower.

d] A orange flowers mating to produce an orange flower.​

Answers

Answer:

c] A red flower and a yellow flower mating to produce an orange flower.

Explanation:

An incomplete dominance in biological terms means a situation where one allele doesn't totally take the expression in a gene, but rather the two parental traits combine to form a secondary trait. As a result of this, a third phenotype comes up, with the physical trait being a mix of the phenotype of the parents.

Therefore, an example of incomplete dominance is a red flower and a yellow flower mating to produce an orange flower.

Answer:D

Explanation:

D is a Orange with orange meaning its incomplete dominance because it both the same theres no other color dominance the other

During transcription, RNA polymerase synthesizes RNA from a DNA template with the help of accessory proteins.

a. True
b. False

Answers

Answer:

The correct answer is a. True

Explanation:

The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).
