These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?

Answers

The correct answer is B. S-curve

Explanation

There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

In most cases of multiple myeloma, the excess antibodies found in the blood all share an identical protein sequence (thus they have the same structure). Consider such a case where all of the antibodies are identical and think about the cell(s) of origin. How many different B cell clones gave rise to this immune cancer?

Answers

Answer: One single B cell clone gave rise to this immune cancer.

Explanation:

The body's cells divide and grow in a completely regulated manner, following an orderly cell cycle that indicates when a cell should die by apoptosis. With this regulation, it is controlled that there are no aging or mutated cells that grow and affect the organism. Cancer is a genetic disease caused by changes in these genes that control how our cells function. These changes, genetic mutations, can occur randomly in the body or can be inherited from parents. When a cell has its functions altered, they begin to grow out of control and in doing so, form masses called tumors that consume the body's resources and energy and crowd out normal cells, preventing them from fulfilling the biological functions necessary for life. Practically, any cell can become a cancer cell and migrate to other areas of the body.

Multiple myeloma is a type of plasma cell cancer. These cells are found in the bone marrow (tissue inside the bones) and are an important component of the immune system, which is made up of several types of cells that work together to fight pathogens and disease. Some cell types are B and T lymphocytes, and myeloid cells such as macrophages, dendritic cells, etc. When B cells respond to an infection with the participation of T cells that present pathogen-derived antigens to them, they mature into plasma cells. Plasma cells produce antibodies that help the body attack and destroy pathogens as well as cancer cells. These antibodies are proteins that bind to antigens that are also proteins found on the surface of the pathogens or cells to be attacked and "mark" them for destruction by other types of immune cells, such as macrophages or neutrophils.

When the plasma cells become cancerous and grow out of control, this is called multiple myeloma, and the mutated plasma cells produce abnormal antibodies. The overgrowth of plasma cells in the bone marrow can crowd out normal blood cell-producing cells, causing low blood cell counts. This can cause anemia which is characterized by a shortage of red blood cells, and thrombocytopenia which means a low level of platelets in the blood causing increased bleeding and bruising. Another condition that can occur is leukopenia (a shortage of normal white blood cells), which can cause problems fighting infections.

Then, the abnormal antibodies produced by the cancerous plasma cells will have the same amino acid sequence and therefore the same structure. Remember that an antibody is a protein, and proteins are a polymer of amino acids. This amino acid sequence is determined by the genes since each gene consists of a sequence of nitrogenous bases and every three bases read by the ribosomal apparatus (the one that synthesizes proteins), an amino acid is synthesized. Therefore, if we consider that cancer originates from a single cell that suffered a mutation in its genes and began to divide in an uncontrolled manner, the daughter cells (which are genetically identical to the mother cell) derived from this mutated cell will have the same genes (in this case, altered because they divide and grow in an uncontrolled and deregulated manner). This tells us that a single mutated B cell gave rise to this cancer.

A) a membrane separating the cell from its environment
organic molecules, such as carbohydrates and lipids

B) self-replicating molecules, such as RNA and DNA
Thing

C) inorganic molecules, such as nitrogen and oxygen

Answers

Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)

Explanation:

The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.

When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.

Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur

--> in body cells or

--> during gamete formation.

Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution

Answer:

B (self replicating molecules such as RNA and DNA)

Answers

Answer:

The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.

What is confidence interval?

A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.

The proportion of the range consists of the true value of the factor that will be identical to the confidence level.

In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.

It cannot estimate the plausible values of the unknown parameter of the population.

Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.

Secondly, the precision defined in terms of the width of a confidence interval.
