Stomach acidity is in the range of ph 1 to 2. How might this inhibit the growth of ingested bacteria?

Answers

Answer 1

Stomach acidity is in the range of pH 1 to 2 because of the presence of hydrochloric acid (HCL) and pepsin.

Cells in the stomach are responsible for the secretion of HCL in the stomach lumen.For the clearance of ingested bacteria, a particular range of pH is required. HCl and pepsin present in the gastric lumen can kill the bacteria within 15 min if the pH of the lumen gets maintained below 3. If the pH of the lumen increased by 4, it can cause bacterial overgrowth and the establishment of infection.

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?

Answers

Answer:

epigenetics chamges take place.

Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.

Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.

Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.

What is the epigenetic pattern?

Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.

Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

He thinks that the crabs choose their shells based on the shells' color and wants to design an experiment to test this. Which of these steps should the student include in his experiment? A. He should add shells that are different colors, but the same size and type, to the tank and observe which shells the hermit crabs choose. B. He should observe hermit crabs in their natural environments and determine how shells help protect them from predators. C. He should place the hermit crabs in different tanks and change the temperatures in the tanks to see if it effects their shell selection. D. He should gather shells that are different sizes and different colors, place them in the tank with the hermit crabs, then observe which shells they choose. Reset Next Question

Answers

A. He should add shells that are different colors, but the same size and type, to the tank and observe which shells the hermit crabs choose.

Durning an experiment you need to keep everything the same but only change the certain things based on your theory.
Such as how the student wanted to see if the color attracted the crab. If he had changed the size and type of the shell then the crab would have chosen the bigger one as they tend to grow into larger shells.

For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

what do the arguments for and against the use of stem cells in medical research share?​

Answers

Answer:   Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:

Parkinson’s Disease

Alzheimer’s Disease

Heart Diseases, Stroke and Diabetes (Type 1)

Birth Defects

Spinal Cord Injuries

Replace or Repair Damaged Organs

Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future

Stem cells may play a major role in cancer

Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society

Cons

"We should not mess with human life."

"Humans should not be trying to play God"

Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.

Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.

The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.

The arguments for and against the use of stem cells are:

Arguments for the use of stem cells in medical research are:

1. The stem cells enhance the growth and development of healthy skin tissue.

2. The cells can be used to enhance the production of collagen.

3. The study of stem cells helps in understanding the causes of disease.

Arguments against the use of stem cells in medical research are:

1. The use of stem cells for research harms human life and dignity.

2. People believe that killing blastocysts or stem cells is equal to taking a human life.

3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.

Therefore, the use of stem cells for research can be fruitful or disadvantageous.

Which of the following answers is NOT correct with regard to convection currents?

A. Convection currents in magma drive plate tectonics.

B.Convection currents in magma are a result of density differences.

C. Convection currents play a role in the movement of Earth’s inner core.

D. Convection currents in magma are caused by temperature differences.

Answers

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Convection currents play a role in the movement of Earth’s inner core.

Thus, the correct option for this question is C.

What is Convection current?

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.
