what is the mechanism in type ii hypersensitivity reactions? a. antibodies bind to soluble antigens that were released into body fluids and the immune complexes are deposited in the tissues. b. antibodies coat mast cells by binding to receptors that signal its degranulation followed by discharge of preformed mediators. c. antibodies bind to the antigens on the cell surface. d. cytotoxic t lymphocytes or lymphokines-producing th1 cells attack and destroy cellular targets directly.

Answers

Answer 1

Cells are coated with antibodies when they attach to receptors that indicate their degranulation and release of mediators that have already been produced. Option (b) is Correct.

The production of antibodies against the soluble antigen is mediated by immunoglobulin E (IgE), and is referred to as type I hypersensitivity or an instantaneous reaction. This activity examines the diagnosis, treatment, and involvement of interprofessional teams in the care of individuals with type I hypersensitivity. The immune system is essential for keeping the body healthy and defending against microbial invasions.

The same system, meanwhile, can also result in heightened immunological and inflammatory reactions, which have negative effects known as hypersensitive reactions. Type I, Type II, Type III, and Type IV reactions are the four conventional categories for hypersensitivity reactions. A more recent classification that divides the reactions into seven categories and takes into account various immune system components was developed by Sell et al. However, the traditional Type I hypersensitivity reactions will be the main topic of this essay.

QUESTION 5 Which of the following is not a lymphocyte? a.Natural killer cells b.T-cells c.B-cells d.Macrophages

Answers

Macrophages are not a lymphocyte. There are three primary kinds of lymphocytes: B cells, T-cells, and natural killer cells.

The T-cells, B-cells, and the natural killer (NK) cells are known as lymphocytes since they start from similar progenitor cells known as normal lymphoid progenitor cells. Lymphocytes are a sort of white platelet (or leukocyte). They assist a life form with battling diseases. They happen in a safe arrangement, everything being equal. In human grown-ups, lymphocytes make up about 20 to 40 percent of the complete number of white platelets. They are tracked down in the course and furthermore are packed in focal lymphoid organs and tissues, like the spleen, tonsils, and lymph nodes, where the underlying safe reaction is probably going to happen.

Answers

Resource partitioning may have occurred between different groups, resulting in competitive exclusion and speciation during the evolutionary history of hornbills. thus correct option (A)

Several species of birds have huge, horn-like bills, and these birds are known as hornbills. There are 54 species of hornbill, with 31 species found in Asia and 23 in Africa, predominantly in tropical rain forests and savannahs. East of the Wallace Line, just four species are present.

About 15 million years ago, hornbills first emerged in the fossil record. They appear in several tribes' mythologies from Southeast Asia and Indonesia. The hill tribes of Borneo believe that rhinoceros hornbills carry souls to the afterlife. Every five to seven years, hornbills are celebrated in western Borneo. They serve as faithfulness symbols on Sumba.

Hornbills are found only in the Old World. Toucans are regarded as their New World equivalent. The largest hornbill are the size of turkeys. The smallest is the size of doves. Many large ones have horn-like casques on their bill. Some bird live as long as 45 years.

As a result of deforestation, habitat loss, and poaching for their bills, feathers, and flesh, several hornbill species are endangered or threatened. Some people have died after ingesting poisons placed out for animals. Others are kidnapped by poachers, who may fetch up to $1,000 per chick for the eggs of certain species.

Answers

C) As force increases, the rate acceleration increases. As force increases, the rate acceleration increases.

According to Newton's second law of motion, the force applied to an object is directly proportional to the acceleration it experiences. This means that if you apply more force to an object, it will accelerate more quickly. Conversely, if you apply less force to an object, it will accelerate more slowly.

So in this case, if the student measured an increase in force and an increase in acceleration, it is reasonable to conclude that the amount of force applied affects the acceleration of the toy car. This is the interpretation of the data that led to the conclusion.
