Answer:

Every cell of their body contains defective , loss of function allele of a tumor suppressor gene

Explanation:

Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers

Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.

The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

Answer:

Vagus nerve is the 10th cranial nerve. It is long start from brain and distributed over head, thorax and abdomen.

Explanation:

1.   In the salivary gland the secretory and vasodilator effect on afferent nerve is mediated mainly by parasympathetic reflex which is given by vagus nerve.

2.   Pyloric sphincter is the part present between the stomach and small intestine which regulate the flow of food particles from stomach to the intestine. Vagus nerve control the activities of pyloric sphincter. Vagus nerve help the pyloric sphincter to relax.

3.  Efferent nerves of vagus nerve help the gall bladder to contract. Vagus nerve is stimulating the gastric tract to contract. So the vagus nerve stimulation promotpromotprthe production of CCK hormone and it will lead to the contraction and secretion of hormones from the gallbladder. Those contractions will help the gallbladder to empty the hormones from gallbladder.

4.  The efferent nerves of vagus nerves act on the smooth muscles of duodenal papila. As above says it lead to the contraction of smooth muscles and also promote the production of CCK.

Answer: Dorsal.

Explanation:

The neural plate is a region of the dorsal ectoderm that develops into the neural ectoderm. It is a flat structure, with columnar appearing cells, and the formation of the neural ectoderm is the first step in the neurulation process. This region is generated from the thickened mid-dorsal surface opposite the primitive line of the ectoderm. From this epithelial zone the various types of neuronal and glia cells belonging to the nervous system are derived. For the neural plate to be built, it is necessary that the epiblast cells converge towards the midline of the embryonic disc forming a groove of the primitive line, delimiting a longitudinal axis of bilateral symmetry around which the embryonic structures and their organs will be aligned. From this moment on, the embryo will have a rostral (cephalic) and caudal (tail) region as well as a left and right side and a dorsal (back) and ventral (front) surface. From the folding of the neural plate or neurulation, the neural tube and the development of the entire nervous system will be formed.

The neural tube is tubular structure that undergoes modifications and will give rise to a central nervous system structure (encephalon and spinal cord).  The neurulation process begins by means of signals sent by the dorsal mesoderm and pharyngeal endoderm to the ectodermal cells located above these germ layers. These signals cause this area of the ectoderm to elongate into a columnar plate of cells. The elongation allows the differentiation of the cells of the future neural plate, with respect to the pre-epidermal cells surrounding the area.

So, the neural tube is formed by invagination from the dorsal region of the ectoderm (neural plate) induced by the notochord while it is forming. This occurs at the beginning of the third week of conception by a process called neurulation.

Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.

Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.

Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:

- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".

- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.

- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

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.

There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.

These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.

There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

Therefore, You can get infected with hand, foot, and mouth disease if you have the virus on your hands and then touch your eyes, nose, or mouth.

Answer:

the parasympathetic system keeps heart rate lower than the heart would beat on its own.  

Explanation:

The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.

It occurs when there is active absorption of water by roots and transpiration is low i.e. moist and humid conditions. Therefore, guttation generally occurs in the early morning because transpiration is less at that time but water is actively absorbed by the roots.

Answer:

Species are as specific as you can get. It is the lowest and most strict level of classification of living things. The main criterion for an organism to be placed in a particular species is the ability to breed with other organisms of that same species.
