Digestion is the - breaking down of food into molecules small enough for the body to absorb.

What is Digestion?

Breaking down of food into molecules small enough for the body to absorb is a type of chemical digestion. It is a complex process in which the broken down subunits of food particles are absorbed by the lining of alimentary canal with the help of enzymes.

Conversion of glycogen to glucose is called as Glycogenolysis.

Churning actually helps to move chyme ( liquid material ) towards the lower part of the stomach specially towards the pyloric sphincter whereas the absorption of nutrients suspended in water occurs in small intestine.

Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.

A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.

Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.

The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

Nucleus

Explanation:

Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope, eukaryotes are distinguished from prokaryotes(another Domain) which are single-celled organisms that lack a nucleus, and other membrane-bound organelles.

Archaea is another domain but does not have a nucleus.

Nucleus is cell structure distinguishes members of domain eukarya from other organisms.

A nucleus is the organelle within a cell that is membrane-enclosed and houses the chromosomes.

The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such proteins and nucleic acids) into and out of the nucleus.

Each of pollan's chapters focuses on one particular plant and pollan suggests that each plant satisfies a specific human desire. The potato satisfies our desire for control – even more so now that we control its genes.

Though people might consider potatoes ordinary everyday fare, history demonstrates how crucial this vegetable is to humankind. Prior to the invention of the potato, conditions were challenging; many people, particularly in northern European nations, suffered from starvation and famine.

Malnutrition and starvation were eradicated in the countries that embraced the potato, and as a result, they grew stronger and more powerful. It is even conceivable that the potato spread resulted in a transfer of power from southern European nations to northern ones.

Ketone bodies are produced from the incomplete breakdown of fats when glucose is unavailable for the brain and nerve cells.

Ketone bodies are the substances which are produced by the liver during gluconeogenesis. Gluconeogenesis involves formation of glucose during fasting and starvation. The three ketone bodies produced by the liver include acetoacetate, beta-hydroxybutyrate, and acetone.

These compounds are utilized in healthy individuals to provide energy to the cells of the body when glucose is low or absent in the diet.

During fasting or starvation, the glucose levels in the blood quickly decrease which stimulates the body to enter the post-absorptive state. In this state, the body starts converting fat back into fatty acids, glycogen into glucose, and even starts breaking down amino acids for energy.

Explanation:

Hox genes, which are members of the homeotic transcription factor family, establish the segment identity of tissues within the embryo and are essential regulators of the body plan along the cranio-caudal axis (also known as the anterior-posterior axis). This means during embryogenesis, these genes expression follows a precise spatial and temporal colinearity pattern from the 3' to the 5' end of each cluster.

This indicates that Hox genes expressed anteriorly in the developing embryo are typically found at the 5′ end of the same genomic area, a phenomenon known as spatial colinearity. In comparison, those expressed posteriorly are typically found at the 3′ end of the Hox cluster.

The boy's mother, a neurologist noticed sympathetic activation of the radial muscles of the iris dilated the child's pupil.

In humans,  the dilator muscles of the iris contains fibers that extend radially through the iris of the eye and involuntarily contract as available light decreases, thus dilating the pupil.  

Pupillary dilation is controlled primarily by the sympathetic nervous system and interruption of the innervation of the dilator muscle can cause an abnormally small pupil, a condition seen as part of Horner syndrome.

Pupillary dilator increases the size of the pupil to allow more light to enter the eyes. It works in opposition to the pupillary constrictor. The pupil dilation occurs when there is an insufficient light for the normal functioning of eyes or during heightened sympathetic activity, for example during fear .

Answer:

During meiosis i, homologous chromosomes undergo crossing over while they are side-by-side in an event called synapsis.

Explanation:

The synapse's ability to alter as a result of repeated stimulation, reinforcement (such as via reward), or reduction in neurotransmission under other circumstances makes it important. These are referred to as long-term depression or potentiation. Synaptic plasticity, often known as the capacity for change, is what underlies learning in all contexts, including associative learning, associative memory, and episodic memory. You may think of it as residues of neurotransmitters that are reinforced and are used to form memories, routines, and personality traits.

A chemical preservative stops items from decomposing. Some preservatives are used to cure wood or metal, while others are applied to food. Food preservation is "the science that deals with the process of preventing food from decaying or spoiling so that it can be stored in a fit condition for future use." Food quality, edibility, and nutritional content are all guaranteed via preservation.

Drying: The oldest method of food preservation is drying. By using this technique, water activity is reduced, preventing bacterial growth. Drying makes food lighter so it can be transported more readily. Modern drying methods include bed dryers, fluidized bed dryers, freeze drying, shelf dryers, spray drying, commercial food dehydrators, and household ovens, in addition to the traditional methods of using the sun and wind. Examples of dried items using this technique include meat and fruits, apples, apricots, and grapes.

Freezing: Food prepared and frozen is kept in cold storage. Although potatoes can be controlled in dark areas, potato preparations must be frozen.

Smoking: Food is cooked, flavored, and preserved through smoking, which exposes it to wood smoke. Meats and fish are typically smoked because the smoke has antibacterial and antioxidant properties. Assorted smoking techniques are employed, including hot smoking, cold smoking, smoke roasting, and smoke baking. Smoking increases the risk of cancer when used as a preservative.

Vacuum packing creates: By making bottles and bags impermeable, vacuum packing creates a vacuum. Bacteria perish because there is no oxygen in the newly generated vacuum. Typically applied to dry fruit.

Salting and Pickling: Curing, commonly referred to as salting, removes moisture from goods like meat. Pickling is the process of preserving food in a salt solution (brine) or vinegar (acetic acid); in Asia, food is sometimes preserved in oil. At a 20% concentration, salt kills and stops the growth of microorganisms. Pickling can be done in many ways, including chemical pickling and fermentation pickling. To extend the shelf life of commercial pickles, sodium benzoate or EDTA is added.

Sugar: Fruits can be preserved with sugar in syrup form or crystallized form, depending on whether the material to be preserved is boiled in the sugar until it crystallizes, like candied peel and ginger. Another use is for fruit superficially coated in sugar syrup and then glazed. Alcohol and sugar are combined with preserving upscale foods like fruit in brandy.

Lye: Lye, also referred to as sodium hydroxide, makes food alkaline and inhibits the growth of microorganisms.

Canning and bottling: Sealing cooked food in sterile bottles and cans is the definition of canning and bottling. Boiling the container destroys or weakens bacteria. Various amounts of time or space are used for cooking food. The food is more at risk of rotting after the can or bottle has been opened.
