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.

In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.
Answer:
isotonic; the same rate
Explanation:
Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.
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.

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.
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.

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 ?
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.

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