Answer:

Our lungs which are a part of our respiratory system allow us to breathe.  The lung brings oxygen into our bodies called inspiration, or inhalation and send CO2 out known as expiration, or exhalation. Thus said this exchange of O and CO2 is known as respiration.

Answer:

FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture. Foods provide a perfect environment for bacterial growth, due to their provision of nutrients, energy, and other components needed by the bacteria.

Answer:Interviewer: Hello Ma'am, Thank you for taking your time to meet us.

Doctor: No problem. Good Morning.

I : In today's world more and more children are falling prey to disorders that happen during older years. Could improper diet be a reason?

D: Of course. there is so much junk in a child's meals, it is not surprising.

I: What do you thinks should constitute an ideal diet?

D: Less of fried items, of course. Enough of vitamins, carbohydrates, proteins and fats are a must as well. A lot of children drink just a glass of milk for their breakfast and I can't tell you how unhealthy that is. They should be given a proper full breakfast and milk can be given during the evenings after school. Alongwith a proper diet, it is also necessary for them to have physical activities like sports.

I: Yes..

D: Completely avoiding junk food in itself can being about a lot of change.

I: I see.. Thank you, ma'am. Have a nice day.

Answer:

B Asthma

Explanation:

Inflammation and Constriction of the Airways Are Hallmarks of Asthma. Asthma is a chronic disorder involving soreness and swelling of the interior airway walls. It can be triggered by the inhalation of particles from the air. Physical activity or respiratory infections may also contribute.

"Population education" is defined in this paper as "the planned and in- tentional educational activities in the school curriculum for the study of human population dynamics, their effects and how they are affected by other economic, social and political factors of human societies."'

Carrot

Explanation:

because it's not meat

Answer:

Carrot

Explanation:

Other options are non-veg and rich in proteins.

Answer:

A blood cell carries Hemoglobin. A neuron doesn't have hemoglobin, and uses other proteins.

Explanation:

Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

Answer:

Neurons are surrounded by a cell membrane.

Answer:

jewelry can act as a reservoir for germs

Explanation:

The fact is, everyone carries disease-causing microorganisms on and in their bodies — and jewelry can act as a reservoir for germs. That's why if you're a food worker, you should refrain from wearing from wearing anything fancier than a plain ring on your arms and hands when you work.

Explanation:

Bacteria and viruses can live outside of the human body (such as on a countertop) sometimes for many hours or days. But parasites need a living host to survive. Bacteria and parasites can often be killed with antibiotics. But these medicines can't kill viruses.

Nanoscale Drug-Delivery Systems

Anthony Singer, ... Shyam S. Mohapatra, in Nanocarriers for Drug Delivery, 2019

5.2 Challenges of Systemic Circulation and Cellular Internalization

In systemic circulation there is a danger of fouling, which is essentially the loss of function of NPs due to degradation, alteration, or mild to severe denaturation due to natural internal interactions during administration [60]. This must be accounted for in the design of the nanoformulation by conjugation of antifouling (stabilizing) agents that will maximize the stability and protection of its conjugate. In addition, any specific barriers encountered during administration must be taken into consideration by employing a mechanism to overcome the barrier. Stabilizing agents also aid in extending the half-life, maximizing delivery to the target site, preventing nonspecific premature drug release or nonspecific cellular uptake, and overall eliminating cytotoxic effects. Targeting also enhances specific delivery. Another challenge of free NPs in the systemic circulation is the prevention of opsonization, which signals for degradation and clearance from the bloodstream. This can be prevented by conjugating specific polymers, such as PEG. Size also plays a role in whether the NP is detected. Last, any NP that enters the human body and is immersed in body fluids can become coated by natural body proteins forming a protein corona [60]. In response, the NP's in vivo physicochemical interaction can be inhibited or altered to the point that its therapeutic function is lost. For example, a natural protein can successfully compete for a targeting moiety and prevent the intended ligand–receptor interaction. However, the protein corona can be controlled by functionalization to inhibit its formation or bond specific types of proteins that could aid in delivery or protection [60].

If there are no extracellular release stimuli when a target cell is reached, the intracellular delivery for an NP highly depends on its ability to survive cell entry, or internalization. This process typically relies on a phagocytic path of entry, which exposes the NP to acidic environments and also requires endosomal vacuole escape [53]. Other paths may include entry through pores in the cell membrane or facilitation by transmembrane proteins. If release is not intended to be cytoplasmic, then conjugates to aid in intracellular trafficking must be employed to cause organelle-specific drug delivery [54]. Mitochondria and the nucleus of a cell are often targeted organelles, but both have membranous barriers that must be overcome.

Most importantly, nanotherapeutics must be safe. Primarily, the body's cytotoxic response is evaluated, but on top of what has been mentioned in the last paragraphs about stable targeting, the components of the nanotherapeutic must be biodegradable. This means that any unused component, such as the nanocarrier and its conjugates, can be safely broken down and excreted from the body without induction of a cytotoxic effect. In addition, the utilization of biocompatible components (those that are either found naturally in the body or can be naturally metabolized or defended against) severely reduces cytotoxicity [14].

Answer:

It's A(right atrium)

Explanation:

In the systemic circulation, blood travels out of the left ventricle, to the aorta, to every organ and tissue in the body, and then back to the right atrium.
