Factors determine energy a human being requires in a day

Answers

Answer 1
Human energy requirements are estimated from measures of energy expenditure plus the additional energy needs for growth, pregnancy and lactation. Recommendations for dietary energy intake from food must satisfy these requirements for the attainment and maintenance of optimal health, physiological function and well-being. The latter (i.e. well-being) depends not only on health, but also on the ability to satisfy the demands imposed by society and the environment, as well as all the other energy-demanding activities that fulfil individual needs.

Energy balance is achieved when input (i.e. dietary energy intake) is equal to output (i.e. total energy expenditure), plus the energy cost of growth in childhood and pregnancy, or the energy cost to produce milk during lactation. When energy balance is maintained over a prolonged period, an individual is considered to be in a steady state. This can include short periods during which the day-to-day balance between intake and expenditure does not occur. An optimal steady state is achieved when energy intake compensates for total energy expenditure and allows for adequate growth in children, and pregnancy and lactation in women, without imposing metabolic, physiological or behavioural restrictions that limit the full expression of a person’s biological, social and economic potential.

Within certain limits, humans can adapt to transient or enduring changes in energy intake through possible physiological and behavioural responses related to energy expenditure and/or changes in growth. Energy balance is maintained, and a new steady state is then achieved. However, adjustments to low or high energy intakes may sometimes entail biological and behavioural penalties, such as reduced growth velocity, loss of lean body mass, excessive accumulation of body fat, increased risk of disease, forced rest periods, and physical or social limitations in performing certain activities and tasks. Some of these adjustments are important and may even increase the chances of survival in times of food scarcity.

Mark Brainliest please

Answer:

In autotrophic nutrition,the organism makes its own food from inorganic raw material like carbon dioxide and water present in the surrounding by using sunlight. For Example : Green plants,autotrophic bacteria. Those organism which can make their own food from carbon dioxide and water is called autotrophs.

Only plants are capable of combining simple inorganic substances into complex organic ones capable of sustaining life. An organism which can carry out this method of nutrition is said to be autotrophic which means self-feeding. There are two types of autotrophic nutrition, chemosynthesis and photosynthesis.

What is biodiversity?

Biodiversity is a word used when all the different varieties of life forms, therefore, animals, microorganisms, and plants all come together and work. both biotic and abiotic factors are included in biodiversity. There can be a variety of species that co-exist altogether.

There are three levels of biodiversity species diversity, ecosystem diversity, and genetic diversity. Examples are pine trees, sunflowers, blue whales, tigers, and all types of microorganisms. The threats to biodiversity are an invasion of alien species and an increase in the number of predators.

Therefore, biodiversity is all species coexisting altogether.

There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.

Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.

Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.

Anyone know the answer?

Answers

Answer:

the answer c. is correct  

Explanation:

During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.

In the food web above, if new species of insect were introduced that fed primarily on plantains, how would the following populations be affected? Indicate your answer by increase , decrease or no change and include a brief explanation of your reasoning.

A) greenfly

B) rabbit

C) fox

Answers

Answer:

This is a 50/50 answer. I believe it would be fox, sorry if this is incorrect.

Answer:

Greenfly- no change

The greenfly would remain unaffected because it doesn’t rely on plantains.

Rabbit- decrease

The rabbit relies on plantains as food so more competition would result in a decrease in the rabbit population

Fox- decrease

Lesser food means lesser foxes. The foxes prey like the rabbit and mouse eat plantains. If the mouse and fat population goes down so would the fox population.

Answer:

- The blood brain barrier is a layer of cells lining the blood vessels within the brain, acting as a filter that controls the molecules that pass between the blood and the brain.

- An organism's gut microbiota is the collection of all the microorganisms (e.g. bacteria, phages, fungi) that live inside the digestive system of that individual.

- A gap junction is a type of intercellular protein connection between animal cells that prevents leakage of materials through the space between the cells.

- The transmembrane protein occludin is one of the component proteins of a tight junction.

- Germ-free mice lack all microorganisms in their digestive systems, a state achieved by delivering them through cesarean section and raising them in sterile incubators.

- Pathogen-free mice are raised under sterile conditions to limit their exposure disease-causing microorganisms.

Explanation:

The blood-brain barrier is a layer of cells made up of endothelial cells that act to limit the passage of substances from the bloodstream in a more selective manner than endothelial cells of capillaries located in other parts of the body. Gut microbiota can be defined as all the microorganisms (i.e., bacteria) inhabiting the mammalian gastrointestinal tract, which helps to ferment non-digestible substrates (e.g., dietary fibers). A gap junction is a class of cell junction that is formed between cells contacting each other which allows small molecules (e.g., water, ions, metabolites, microRNA sequences, etc) to pass through this intercellular communication.  In vertebrate animals, cell junctions can be divided into 1-gap junctions (communication between cells), 2-tight junctions (occludin junctions), and 3-adherens junctions, hemidesmosomes and desmosomes (anchor junctions). Tight Junctions are composed of multiple proteins including transmembrane proteins such as occludin, tricellulin, junctional adhesion molecule (JAM), and one member of the claudin protein family. Germfree animals are research animals that have no microorganisms living in or on them, which are housed in controlled/isolated conditions to prevent any type of contamination. Finally, pathogen-free animals are research animals that are guaranteed to be free of particular pathogenic (harmful) microorganisms.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?

Answers

Answer:

Smaller and slower axons are those related to temperature, itching and pain.

Explanation:

As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.
