Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. It aids in cell regeneration and repair in your body.
Sustainable agriculture is the practice of farming in a way that satisfies society's current demands for food and textiles without endangering the ability of present or future generations to meet their own needs. It might be founded on knowledge of ecosystem services.
The biochemical and physiological process by which an organism uses food to sustain its life is known as nutrition. Consumption, absorption, assimilation, biosynthesis, catabolism, and excretion are all included. Nutritional science is the field of study that focuses on the physiological aspects of nutrition.

Explanation:
Why is the sympathetic nervous system referred to as the fight or flight system?
Answers
As you can see from the diagram below, the human nervous system is divided into two main components, the peripheral nervous system and the central nervous system.
The peripheral nervous system is further divided into two components. The somatic nervous system involves the voluntary movement of skeletal muscle. When you decide to raise your cup of coffee to your mouth, that is the somatic nervous system at work activating the appropriate muscles. The second component of the PNS is the autonomic nervous system, which controls processes that are out of our conscious control.
The autonomic nervous system is further subdivided into the parasympathetic nervous system and the sympathetic nervous system (which you are interested in). In very generalized terms, they have antagonistic effects on each other. The sympathetic nervous system generally activates the body, whereas the parasympathetic nervous system primarily acts to relax the body. This is a simplified view of things, but it is useful to think of it in this way.
The sympathetic division of the autonomic nervous system increases heart rate, inhibits digestion, relaxes bronchi in the the lungs to allow more airflow, causes the release of glucose from the liver, and relaxes the bladder. All of this activates the body, prepares it for a "fight".
In contrast, the parasympathetic division reduces heart rate, constricts bronchi in the lungs, and increases blood flow to the digestive tract. It has been called the "rest and digest" system.
As you can see from the diagram, the nerves of the parasympathetic nervous system come directly from the brainstem and spinal cord. However, with the sympathetic nervous system, there are "ganglia" (groups of cell bodies) outside the spinal cord itself.
Interestingly, the parasympathetic nervous system only uses Acetylcholine (ACh) to exert its effects on organs, but the sympathetic nervous system uses both ACh and norepinephrine (NE) to activate the body.
Its important to remember that the sympathetic and parasympathetic nervous systems are autonomic, meaning we generally have little control over them.

2 the corona
3 the brain
4 the stomach
Answers
The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.
Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.
Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.
This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.
Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

Aerobic is one that uses oxygen in the process of generating energy in the muscles. This type of exercise works a large number of groups rhythmically.

Aerobic respiration is the one that participates in the control and can be probable in three steps: analysis of glycolysis, Krebs cycle and oxidative phosphorylation. When breathing, we soon imagine the inflow of oxygen and the outflow of carbonic acid through our airways.
With aerobic cellular breathing, more and more ATP is broken down so that it generates more energy so that we can continue to perform the exercises. This energy causes cells to break down fats.

The rate of cellular respiration and photosynthesis can increase or decrease because of different factors.
Explain how either the rate of cellular respiration or the rate of photosynthesis can be increased and decreased. Be sure to include details of specific reactions in your answer.
Answers
The main environmental factors that affect photosynthesis are: light, CO2 and temperature. Also, the availability of water and nutrients are important factors.
How to increase the rate of photosynthesis?Plants kept under ideal conditions of luminosity and carbon dioxide concentration increase the rate of photosynthesis as the ambient temperature increases, up to close to 40°C. Above this temperature limit, there will be a drastic reduction not only in photosynthesis, but also in most vital reactions.
The photosynthetic rate, that is, the intensity of photosynthesis that the plant performs, can be changed by the amount of light it receives. The greater this light radiation, the greater the photosynthetic rate, if there is no other factor such as temperature or water availability limiting the process.

Answers
The statement is true. Economic profit equals zero when total revenue (TR) equals total cost (TC).
In Economics, total cost is defined as the sum of costs that is incurred by firm for the production of certain level of output.
Mathematically, it is calculated as:
TC (total cost) = TFC (total fixed cost) + TVC (total variable cost)
Fixed cost refers to a cost that does not change with an increase or decrease in the number of goods or services produced or sold.
Variable cost changes with an increase or decrease in the number of goods or services produced or sold.
Total revenue is also called gross revenue. It is the total amount of income your company brings in from selling your products/services.

2. Bone
A 68-year-old Asian female presents with mildly achy muscles and joints. The aches seem to “come and go” quite often lasting for several days at a time. Upon examination you take note of a hunch-backed appearance on the patient. An x-ray is performed and showed a significant decrease in bone tissue mass. After further diagnostic testing is performed the patient is diagnosed with Osteoporosis. TAKE NOTE: Osteoblast cells build bone matrix while osteocytes maintain the matrix. Osteoclast cells break down bone matrix and reabsorb the nutrients.
Using your knowledge of the human physiology, which of the following do you predict is a potential cause of the Osteoporosis?
A. Decreased osteoblast activity B. All choices are potential causes
C. Increased osteoclast activity D. Secondary to external factors like drugs/cancers
Answers
Osteoporosis causes bone density to decrease due to decreased osteoblast activity, increased osteoclast activity, and external factors like long-term medication. Option B. All choices are potential causes.
What are the factors that promote osteoporosis?
Let us first review what the bone cells are and their functions,
• Osteoprogenitores → in charge of osteocytes production
• Osteocytes → maintain the matrix
• Osteoblasts → Synthesize and secrete osteoid matrix that will later calcify
• Osteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.
Osteoporosis is a no-symptoms disease -silent- that causes a decrease in the bone mineral and mass density and might change the bone structure.
Osteoporosis weakens the bone until it breaks. So this affection becomes evident when a fracture occurs.
Several factors lead to osteoporosis development. Among them, we can mention,
genetic factors, habits factors (lifestyle),hormonal alterations,drugs/medication
The increased rate of bone resorption is the major mechanism by which osteoporosis occurs. It deteriorates bone structure and decreases bone density.
Bone resorption and deterioration might be caused by
a decrease in osteoblast activity, leading to the decrease in osteoid matrix formation and calcification,an increase in osteoclast activity, enhancing the activity of these phagocytic cells.
Other external factors also increase the probability of developing osteoporosis. Some of them are,
long-term medications (for instance, those used in cancer treatment) excessive alcohol consumption and smokingsedentary lifestylepoor dietAccording to this framework, the potential causes of the Osteoporosis are Decreased osteoblast activity, Increased osteoclast activity, Secondary to external factors like drugs/cancers.
Hence, option B is correct, All choices are potential causes.
