The most frequent source of food-borne disease is bacteria. These little, single-celled creatures are ubiquitous.

Another frequent cause of outbreaks of food-borne illness is viruses like the norovirus or hepatitis A.

Viruses can travel on any sort of food, but they need a living host like a person or animal to exist and multiply. People become ill after consuming food that has been tainted with a virus.

Parasites are living things that reside on or in humans or other animals. When people drink or eat something that contains the parasites, they are then passed to humans.

Small, single-celled bacteria called protozoa are present in both food and water. The majority of protozoa are helpful to people, but some, like giardiasis, are dangerous and bring on food-borne illnesses.

An abnormal protrusion of the eyeball out of the orbit is called exophthalmos.

An abnormal protrusion of the eyeball, or exophthalmos, is an acquired condition of the eye where the eyeball is pushed forward out of the orbit due to a swelling behind the eye. The swelling can come from an increase in the size of the muscles, fat, or tissues behind the eyeball.

Exophthalmos is commonly associated with Graves' disease, an autoimmune disorder where the immune system attacks the thyroid, causing it to produce too much of the hormone, thyroxine. Common symptoms of exophthalmos include vision problems, dry eyes, double vision, irritation, and redness.

Treatment for exophthalmos can vary depending on the underlying cause. If the cause of exophthalmos is an autoimmune disorder, such as Graves’ disease, drugs are prescribed to control the disease. Surgery may also be necessary to correct the protrusion, and eye lubrication and artificial tears may be prescribed to reduce dryness or irritation.

Answer:

Chromosomes are positioned in the middle of the cell during metaphase.  

Explanation:

During metaphase, the centrosomes are at opposite poles or sides of the cell.  The spindle apparatus is formed and the nuclear membrane has dissolved.  The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions.  The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division.  The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart.  They are important for the cell to be able to divide.  

The answer is True. The area between the two cells is known as the synaptic cleft.

There is a distinct separation between the presynaptic and the postsynaptic membrane.

The difference tells us about there must be some intermediary signaling mechanism between the presynaptic neuron and the postsynaptic neuron.

The presynaptic neuron is the cell that sends information whereas the postsynaptic neuron is the cell that receives information

The synaptic cleft is the small space separating the presynaptic membrane and postsynaptic membrane and the synaptic vesicle is an organelle that houses chemical neurotransmitters.

Neurotransmitters are chemicals that are released by neurons and bind to receptor sites, which are synthesized in the neuron, and packaged into vesicles.

The correct sequence of the common pathway of blood clotting from the beginning to the end is as follows:

The mechanism of blood clotting initiates when there is damage to a blood vessel. Platelets immediately begin to stick to the cut edges of the vessel and liberate chemicals in order to attract even more platelets. A platelet plug is formed, and the external bleeding stops.

The mechanism of blood coagulation takes initiated with the injury or when blood is leaked. Whenever there is a rupture of blood vessels or damage is caused to blood, a complex of substances called the prothrombin activator complex is formed.

The activators of prothrombin convert prothrombin into thrombin. Thrombin acts as an enzyme and converts fibrinogen into fibrin threads. These threads have now formed a polymer and activate factors that terminate the entire process.

Therefore, the correct sequence of the common pathway of blood clotting from the beginning to the end is well described above.

During the Guides phase of HIV disease, the insusceptible framework turns out to be seriously compromised, prompting a pattern of progressively extreme side effects. This cycle happens because of the accompanying elements:

Declining CD4+ Lymphocytes: HIV explicitly targets and obliterates CD4+ White blood cells, which assume a pivotal part in planning a safe reaction. As the infection duplicates and contaminates more CD4+ Lymphocytes, their numbers decline, debilitating the insusceptible framework's capacity to actually ward off diseases and sicknesses.

Pioneering diseases: With a debilitated insusceptible framework, people with Helps become defenseless to deft contaminations. These are contaminations brought about by organic entities that normally don't cause extreme disease in individuals with sound safe frameworks. Deft contaminations can go from bacterial, viral, parasitic, and protozoal diseases. These diseases can be extreme, relentless, and testing to treat, adding to the deteriorating of side effects.

Industrious aggravation: Persistent safe actuation and irritation are signs of HIV contamination. The continuous insusceptible reaction and aggravation further harm the safe framework and imperative organs after some time. This tireless irritation can prompt the advancement of unexpected complexities, like cardiovascular illness, neurological issues, and certain malignant growths, which add to the movement of side effects.

HIV transformations and viral variety: HIV has a high change rate, prompting the improvement of viral variations that can dodge the safe framework and antiretroviral treatments. As the infection advances, it turns out to be harder to control and treat, adding to the deteriorating side effects and treatment challenges.

Generally speaking, the pattern of progressively extreme side effects during the Guides phase of HIV contamination is driven by the dynamic obliteration of the safe framework, powerlessness to shrewd contaminations, persevering aggravation, and viral changes that compromise the body's capacity to protect against contaminations and illnesses.

The statement, "the decapitated plant shoot would have grown straight up with no bending after the block was placed squarely on top of the cut plant shoot surface" is False.

Decapitation refers to the complete removal of an organism's head. The decapitated organism will die immediately if the brain is removed or damaged. It's a major issue in the plant world. When a plant is decapitated, it exhibits certain behaviors. Plants react to decapitation in a variety of ways. When a plant is decapitated, it will usually generate a wound response, which will begin with a surge of auxin hormone signaling from the site of the wound.

After decapitation, the plant's stem, which is severed from the rest of the plant's tissues, undergoes considerable alterations. Some plants might increase the growth of branches, whereas others might generate new shoots. Instead of growing straight up, the decapitated plant shoot would have bent. The study demonstrates that the removal of the plant's primary shoot apical meristem caused a surge in growth hormones in the nearby side buds. These side buds grew into new branches, resulting in a bushier plant. A block placed squarely on top of a cut plant shoot surface has no effect on the growth direction of the plant.

DNA replication is so efficient because of the hydrogen bonds that form between the complementary base pairs of DNA. These hydrogen bonds are strong and stable, allowing for the two strands of DNA to be accurately and quickly replicated. Additionally, the double-stranded nature of DNA allows for the two strands to be replicated simultaneously, further increasing the efficiency of the process.

DNA replication is so efficient in terms of bonds because it involves the formation of strong covalent bonds between the nucleotides in the new strand of DNA.

The covalent bonds during DNA replication provide stability and ensure that the new strand of DNA is an exact copy of the original strand.

During DNA replication, the original strand of DNA is unwound and separated into two single strands. Each single strand then serves as a template for the synthesis of a new complementary strand of DNA. This process is catalyzed by the enzyme DNA polymerase, which adds nucleotides to the new strand of DNA, forming strong covalent bonds between the nucleotides.

The formation of these covalent bonds is what makes DNA replication so efficient. Without these strong bonds, the new strand of DNA would be unstable and prone to errors, which could result in mutations or other problems. However, because of the strong covalent bonds, the new strand of DNA is stable and accurate, ensuring that the genetic information is faithfully replicated and passed on to the next generation.

The weight of cholesterol is 0.6 g.

Here use the concept of molarity.

The amount of a substance in a specific volume of solution is known as its molarity (M). The moles of a solute per liter of a solution is known as molarity.

Molarity = no. of moles/volume (in L)

Given,

Molarity, M = 5.0 mM = 5 × 10⁻³ M

Volume, V = 315 mL = 315 × 10⁻³ L

To calculate,

Weight of cholesterol =?

We know that,

Molecular mass of cholesterol, C₂₇H₄₆O = 386

No. of moles = weight/ molecular mass

The formula is modified as,

Molarity = weight of cholesterol/ (molecular mass) (Volume)

Put the values in the formula,

5 × 10⁻³ = weight of cholesterol/ (386) (315 × 10⁻³)

Weight of cholesterol = 5 × 10⁻³  (386) (315 × 10⁻³)

                                    = 0.6 g

Hence, the weight of cholesterol is 0.6 g.

Cytokinesis in plant cells results in the formation of a cell plate between the new cells, while cytokinesis in animal cells only pinches the cell membrane in half. This is a true statement. The cell plate forms the cell wall of the plant.

The cytokinesis is a process by which the cell is divided into two daughter cells, each containing some of the cytoplasm of the parent cell. This process of cytokinesis is different in animals and plants. Animal cells' cytokinesis starts at the end of the telophase. Cell actin and myosine proteins pinch the cells, and as a result, the cell divides into halves.

In plant cells, there is no pinching mechanism. There is a cell plate formed in the middle of the dividing cell by the accumulation of the vesicles, cellulose, etc. Then daughter cells are formed.

Hence, it is a true statement that cytokinesis in plant cells results in the formation of a cell plate between the new cells, while cytokinesis in animal cells only pinches the cell membrane in half.
