Saprozoic nutrition is characterized by pinocytosis of soluble nutrients and subsequent formation of phagocytic vacuoles.

Saprozoic nutrition entails the absorption of simple organic molecules and dissolved salt from the environment in order to fulfil the organism's nutritional needs. Saprophytic nutrition is the mechanism of nutrition in which an organism receives nutrients from dead and decaying organic substances.

The arrangement, in which flagella are distributed all round the bacterial cell, is known as peritrichous.

Flagellum is singular while flagella are plural which is frequently used for locomotion. A flagellate could also be a cell or organism with one or more whip-like appendages called flagella. peritrichous having a spiral line of modified cilia around the cytostome peritrichous protozoans.

Follicle-stimulating hormone is responsible for the onset of puberty in females.

At this stage of puberty, the Follicle-stimulating hormone hormone begins producing and induces the development of ovaries which result in the hormone estrogen. This hormone is also responsible for the development of secondary sexual character; induces voice change, body hair, breast, feminine shape, and external genitalia.

Erythroblastosis fetalis, also known as hemolytic disease of the newborn, is a condition that occurs when there is an incompatibility between the Rh factors of the mother and the baby. If the mother is Rh- and the baby is Rh+, the mother's body may produce antibodies against the Rh factor, potentially causing harm to the baby.

The blue color of the vaginal mucosa during pregnancy is a sign of Chadwick Sign.

• Chadwick's sign is the bluish discolouration of the vagina, cervix, and labia.
• It is due to the result of increased blood flow.
• It is first described in 1836 by Dr. Étienne Joseph Jacquemin.
• It was named after James read Chadwick who presented a paper in the American Gynecological Society in 1886.

The scrub nurse assists the surgeon by providing appropriate surgical instruments and supplies, maintaining strict surgical asepsis and, with the circulating nurse, accounting for all gauze, sponges, needles, and instruments. The circulating nurse assists the surgeon and scrub nurse, positions the patient, applies appropriate equipment and surgical drapes, assists with gowning and gloving, and provides the surgeon and scrub nurse with supplies.

Proline is an imino acid.

Because it contains the –C = NH – OH group, proline is classified as a secondary amino acid, sometimes known as an imino acid.

Delta waves in Electroencephalogram (EEG) are usually associated with the deep stage 3 of NREM sleep (also known as slow-wave sleep). In case of brain death, EEG shows no brain activity at all.

Signs of brain death include

• Pupils do not respond to light
• No reaction to pain
• Absence of corneal reflex
• Absence of oculocephalic reflex (eyes do not move when head is moved)
• Absence of oculovestibular reflex (Eyes do not move when ice water is poured into the ear)
• Absence of gagging reflex
• Absence of breath when the ventilator is switched off.
• No brain activity in EEG

Patients with peripheral vascular disease often have nerve damage as a result of inadequate tissue fusion. Ischemic pain is more worrying. This refers to extreme pain that is caused by a combination of PVD and inadequate fusion. Ischemic pain is often intensified due to poor cardiac output.

ECG test is not used to diagnose neurological problems.

• ECG is used to assess the electrical activity of the heart.
• It helps to assess cardiac rhythm and rate.
• It plays mo part in detecting neurological problems.

The following tests are used to diagnose neurological problems:

• EEG
• CT scan
• MRI
• Electromyography (EMG)
• Lumbar puncture
• Myelogram
• Neurosonography

The nurse always should clean around a wound drain, moving from center outward in ever-larger circles, because the skin near the drain site is more contaminated than the site itself. A Jackson-Pratt (JP) drain is used to remove fluids that build up in an area of the body after surgery. The JP drain is a bulb-shaped device connected to a tube. One end of the tube is placed inside the client during surgery. The other end comes out through a small cut in the skin. The bulb is connected to this end. The patient may have a stitch to hold the tube in place.

Cyanobacteria require light as a source of energy to perform photosynthesis. Fungi and viruses are unable to perform photosynthesis and are heterotrophic. Cyanobacteria are a phylum of Gram-negative bacteria that obtain energy via photosynthesis.

Hematinics are drugs which when administered favors erythropoiesis i.e. synthesis of red blood cells and increase the oxygen carrying capacity of the blood.

Hematinics are substances that are essential to the proper formation of the components of blood. Examples of hematinics include folic acid, vitamin B12, and iron. In addition, vitamin D, which helps maintain the health of bones—the reservoirs of new blood cells—may also have a role in protecting hemoglobin and in stimulating the formation of new blood cells.

The nurse must consider the patient’s cognitive abilities to understand drug instructions. If not, the nurse must find a family member or significant other to take on the responsibility of administering medications in the home setting. The patient’s ability to recover, occupational hazards, and socioeconomic status do not affect drug administration.

Spirochetes are flexible and can twist and contort their shape, whereas spirilla are relatively rigid. Treponema palldium belongs to the spirochetes group and Spirillum volutans belong to the spirilla group.

The gas that does not cause green house effect is N₂ (g).

Greenhouse gases are those which contribute to greenhouse effect by absorbing infrared radiations. Nitrous oxide, ozone, chlorofluorocarbons are some of the greenhouse gases other than given in the options (A), (B) and (C) of the question. Nitrogen is not a greenhouse gas since it is transparent to infrared light and hence does not absorb it.

Genetic drift is a change in gene frequency in the successive generations of a small population due to chance alone rather than natural selection or gene transfer. The effect of genetic drift on a small population is large as compared to that in the larger population which, owing to its large size and a large number of gametes produced, has a greater probability to accurately represent the allelic frequency of a parental population. An isolated population rules out the possibility of gene flow.

Lungs are enclosed in pleural membrane.

Each lung is enclosed by a double-layered serous membrane, called the pleura. The visceral pleura is firmly attached to the surface of the lung. At the hilum, the visceral pleura is continuous with the parietal pleura that lines the wall of the thorax.

To ensure homogenization when diluting powdered medication in a vial, the nurse should roll the vial gently between the palms.

Gently rolling a sealed vial between the palms produces sufficient heat to enhance the dissolution of powdered medication.

Salivary amylase is an enzyme present in the human saliva which is produced by the salivary glands. It helps in the process of digestion as it breaks down complex carbohydrates such as starch into simpler sugars like glucose and maltose. It is also called ptyalin.

The chromosome Number of pairs in a human ovum is 23 in which 22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.

Platelet transfusions may be given to prevent bleeding when the platelet count falls down. In a study of bleeding risks in thrombocytopenic patients, Webert et al. noted that the majority of severe bleeds were preceded by bleeds of lesser severity. Even patients with petechiae (WHO grade 1 bleeding) were 2.5 times more likely to experience clinically significant bleeding on the next day; patients experiencing WHO grade 1 or 2 bleeding were three times more likely to have a severe bleed the next day.

Down syndrome is an example of a chromosomal disorder.

The circle of Willis is located at the base of the brain. The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.

To best ensure the client’s safety, nurse Mary should check the client frequently at irregular intervals throughout the night.

Checking the client frequently but at irregular intervals prevents the client from predicting when observation will take place and altering behavior in a misleading way at these times. Once the patient is deemed to be at risk for suicide, then intervention steps must be initiated right away. The individual must not be left alone. Enlist the help of a support person while at home. The suicidal individual must be treated in a safe and secure place. In addition, the place has to be monitored.

From the following Statement we have these diagram:

From the above diagram, we can have a conclusion that only I conclusion is true.

The least possible Venn diagram is as follows,

Conclusions:

I. All phone are telephone → As, All phone are mobile and all mobile are telephone, all phone will definitely be telephone, hence it is true.

II. Some mobile are phone → As, All phone are mobile, so, some mobile must be phone, hence, it is true.

Thus, both conclusion I and II follows.

The possible Venn diagram is given below:

Conclusions:

I. No dessert is a soap. → True (No soap is a dessert, so we can say that no dessert is a soap.)

II. Some cups are desserts. → True (All desserts are cups, so we can say that some cups are desserts.)

III. Some desserts are soaps. → False (No soap is a dessert, so there is no relation developed between desserts and soaps as some desserts are soaps.)

IV. All cups are desserts. → False (All desserts are cups, but all cups can not be desserts.)

Micrococci such as Micrococcus luteus, Micrococcus varians are found in the ducts of cow’s mammary glands and dairy utensils. They are acid producers and are weakly proteolytic. Micrococcus is a genus of bacteria in the Micrococcaceae family.
