Prolactin hormone allows a woman to produce milk after she gives birth. Thus, the correct option is D.

What is lactation?

Lactation is the process of producing and releasing milk from the mammary glands in breasts. Lactation begins in pregnancy when hormonal changes signal the mammary glands to make milk in preparation for the birth of baby.

It’s also possible to induce lactation without a pregnancy using the same hormones that your body makes during pregnancy. Lactation ends once your body stops producing milk.

Milk ducts increase in size and number when levels of estrogen and progesterone rise. The result is a fuller breast. The mammary glands start to get ready to produce milk.

Kathy Morningside is a 55-year-old woman who has had spells of gastroin- testinal problems over the years (dyspepsia), but a formal diagnosis has never been conclusive. During the past four months, she has had a history of vomiting after some meals and she has lost about 5 kg over this time. Mrs Morningside, together with an old school chum, went to London for a weekend theatre break to see Les Miserables. On the Friday evening, she began to feel unwell, but put it down to her fear of flying. They went to the theatre on the Saturday evening and followed this with a light opera supper at a nearby restaurant. Mrs Morningside suffered a haematemesis and was rushed to hospital with massive bleeding. Her condition settled and follow- ing overnight rehydration, she returned to her home in Newcastle where she was examined by a gastrointestinal consultant. The consultant noted that Mrs Morningside was pale and tachycardic. Her blood pressure was 130/90 mmHg. Rectal examination revealed frank melaena. He attributed the bleed to chronic peptic ulceration, probably as a consequence of long-term use of non-specific anti-inflammatory drugs. He considers her to be at high risk of re-bleeding and may contemplate partial gastrectomy when her nutritional intake has improved. The consultant refers Mrs Morningside to the dietitian as he is concerned about her overall nutritional status. She is currently anaemic (frank iron and possibly megaloblastic/pernicious anaemia). (1) Explain the approaches that may be taken to assess this patient's nutri- tional and dietary status. (2) Consider the dietary assessment more carefully. What may be the prin- cipal focus of the interview with the client? What advance preparation might assist you in the conduct of the assessment interview?

Answers

In order to assess the nutritional status of the patient, the nurse needs to understand the anthropometric measurements of the patient by:

The physical examination helps to understand the physical appearance of the patient and to find out the BMI.Monitoring the intake and output chart helps to understand the nutritional status of the patient.Monitoring the weight helps to understand the accurate weight loss of the patient.

How to depict the information?

The patient is having chronic peptic ulceration so, the focus of the dieticians during the interview must be the collection of history about the previous intake of the anti-inflammatory medications.

In order to confirm it, the dietician needs to ask the patient about the past medical condition and treatments.

As an advance preparation, the dieticians need to study the case sheets of the patient to get an idea about the patient prior to the interview session.

The principal focus of the interview with the client will be the food that the client normally eats and previous treatment regarding the illness.

The advance preparation that might assist in the conduct of the assessment interview is to read extensively on the disease in order to have more information about it.

Answers

Options:

A. reactant

C. substrate

D. protein

Answer:

The catalyzation of a chemical reaction is greatly aided by the enzyme.

What are enzymes?

Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a component of all life. Enzymes are created by our bodies spontaneously.

The structure of the enzyme has an active site where a substrate can bind. The substrate of a complimentary form can approach and bind to the active site because it has a certain shape. Once the substrate is attached to the enzyme's active site, the reaction begins, and a product is created. At the conclusion of the process, the product is generated, released from the active site, and the enzyme is unaltered.

The product that is released from the active site is the appropriate response.

Answer:

RNA has for nitrogenous bases out of which three are the same as DNA. The bases common to both DNA and RNA are Adenine (A), Guanine (G) and Cytosine (C). The one that is different is called Uracil (U).The five carbon sugar in RNA is called Ribose sugar.

Explanation:

DNA consist of four bases that are A,T,C and G. Similarly, RNA also consists of four bases that are A,U,C and G.

Thymine (T) is not present in RNA, instead of it, RNA has Uracil (U) which binds with Adenine (A) by two hydrogen bonds.

The five-carbon sugar that is present in RNA is ribose and that present in DNA is deoxy-ribose. Ribose and deoxy-ribose differ at second carbon. Ribose has an OH at second carbon while in deoxy-ribose, O is missing at second carbon and it has only H.

The diagram below (attached image) represents two cells, X and Y.

Which statement is correct concerning the structure labeled A?

A) It is involved in cell communication in cell X but not in cell y.

B) It represents a cell wall in cell X and the cell membrane in cell y.

C) It prevents the absorption of CO2 in cell x and O2 and cell y.

D) It aids in the removal of metabolic waste in both cell X and Y ​

Cell membrane accomplishes several functions, among them, the removal of cell wastes. Option D. It aids in the removal of metabolic waste in both cell X and Y.

What is the cell membrane?

The cell membrane is a barrier that surrounds the cell content and isolates it from the extracellular space. It is composed of two lipidic layers, proteins, and glucans incrusted in between.

The cell membrane accomplishes many different functions. Among them, we can mention,

Isolation ⇒ It separates the intracellular content from the extracellular space.

Protection ⇒ It protects the interior of the cell from any damaging external factor that might affect its correct functioning.

Transport ⇒ It allows the selective pass of certain molecules or ions.

Substances interchange

⇒  Passive transport → Simple diffusion → through lipids

                                     → Facilitated diffusion → Assisted by channel  

                                        proteins

                                     → Does not need energy

                                    → Depends on the molecule size, the concentration                      

                                       at each side of the membrane, and the charge of      

                                       the ions.

                                      → Occurs in favor of the electrochemical gradient

Active transport → It does the energy to occur

                                → Mediated by carrier proteins

                                → Transport big-sized molecules

                                → Against the electrochemical gradient

Endocytosis/Exocytosis → Active transport mediated by vesicles.  

Communication ⇒ By emission and reception of substances and molecules, the cell can communicate with other cells. This process is always mediated by membranes and their transport proteins or receptor proteins.

In the exposed example X cell represents an animal cell, and Y cell is a plant cell.

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

Among the options, the correct one is D. It aids in the removal of metabolic waste in both cell X and Y
