Explain why there are fewer organisms at higher trophic levels.
Answer:
As we move to higher Trophic levels, we will, generally speaking, see larger animals. And yet, moving to higher trophic levels, these larger animals need to live on smaller energy production from the next trophic level down. As a result, there will usually be fewer animals at higher trophic levels.
Explanation:
Question: What do all organisms
have in common?
Answer:
All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.
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?
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.

What is the impact on human health as we try to stay ahead of the evolutionary process?
(Hint: Consider diagnoses of new illnesses, research and development of medicines, and biological factors like antibiotic resistance).
Staying ahead of human evolution has provided more harm than good impact on human health. According to an evolutionary perspective, several genetic variations interact with surroundings and other genes during development to affect the phenotypes of diseases.
Evolution is a set of intricate mechanisms through which populations of organisms change over time and is regarded by scientists as the fundamental, unifying notion of biology. Genetic adaptations brought about by evolution enable organisms to endure, remain healthy, and flourish.]Often sparked by war and natural disasters, public health evolved via trial and error and the expansion of scientific medical knowledge. Specifically, urbanization and social changes, as well as other aspects of the growth of community life, increased the demand for organized health protectionHence , The process of evolution has significantly impacted human health.

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.

how do blood vessels function to maintain body temperature on hot and cold day
Answer:
Vasodilatation
Explanation:
The blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler — away from your warm inner body. This lets your body release heat through heat radiation.
Answer:
on a hot day they vasodillate causing a lot of blood to flow near the skin surface thus losing heat by convection while voice versa during cold Temp

witchh component is released from the active site of an enzyme during a chemical reaction
Options:
A. reactant
B. product
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.
