a. the relative amount of products and reactants.
b. the formation of glucose.
c. the intermediate reactions needed to break down glucose.
d. the environment in which cellular respiration occurs.
The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.
• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.
• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.
• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.
• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.
Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.

Explain how it is possible for nutrients to be transported to the cells of a flatworm with no circulatory system.
Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

Translation occurs at the ribosome, which consists of rRNA and proteins. ... Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein. A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Once a protein is made, its biochemical and structural properties play a role in producing option a. phenotype.
Phenotype is the observational traits or characteristics of an individual organism. This is an aspect that includes the morphology and the physical form of an organism.
Phenotypes are produced as genetic material that is Chromosomes and DNA are produce proteins, and once the protein is prepared, then proteins, contribute to the structural properties of the cell to make physical form or phenotype.
The biochemical and structural properties plays role in producing the phenotype as the various enzyme and biological reactions help in maintaining physical form and morphology and other aspects.

The correct answer is option D "Mexico"
Explanation:
In February 2008, we gathered grown-up rulers at two discrete overwintering destinations in the Neovolcanic Piles of Focal Mexico:
(I) Sierra Chincua
(ii) Cerro Pelon.
The two locations are situated in Michoacan, Mexico. Butterflies were gathered utilizing standard flying nets with expandable posts.
The commonness of monarchs vigorously infected with OE at every one of these two areas in 2008 was 14.4 and 13.6%.
From ten imitate bunches (five groups for every site), we arbitrarily chose sound and tainted butterflies following starter screening of parasite tests in the field, for a sum of 75 solid and 100 intensely infected monarchs.
