Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.

Define el consepto de fraccion
Answer:
The concept of fraction
Explanation:
What is the concept of fraction tho? Fractions are numbers that represent a part of the whole. When an object or a group of objects is divided into equal parts, then each individual part is a fraction. ... It is divided into a numerator and denominator where the denominator represents the total number of equal parts into which the whole is divided.
A fraction represents the number of parts that we take from a unit that is divided into equal parts. It is represented by two numbers separated by a fraction line.
How can extinctions and expansions occur in the same habitat? Explain your answer.
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
Extinctions are associated with biodiversity changes, thereby affecting species expansion.
What is extinction?Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).
This process of disappearance (extinction) modifies the trophic relationships in the ecosystem.The modification may lead to the expansion of a given species (e.g., prey in the case of predator extinction).In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.

Why can't a hair shaft be used to collect an individual's DNA
Answer:
A hair w/out the follicle and its nuclear DNA, or genetic material in its nucleus, cannot provide individual evidence. Physical examination of the hair can only yield class evidence.
Explanation:
Answer: Hope this helps!
Explanation:
When performing a hair DNA test for the purpose of paternity, it is a must to have a complete hair sample – with hair shaft and hair follicle. On the other hand, if the purpose of hair DNA testing is for forensic use, a cut hair sample even with no follicle can still be of use. However, a complex procedure has to be made.

Do different patterns of electrical signals have unique
meanings?
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.

A lack of CO2 in the flask would have caused reduced O2 production. If O2 , ATP, and NADPH are the by-products of the light-dependent phase of photosynthesis, how does a lack of CO2 cause reduced O2 production
Answer:
Carbondioxide is a reactant of photosynthesis.
Explanation:
Carbondioxide is a reactant of the process of photosynthesis and the product of photosynthesis is oxygen, if there is no or less carbondioxide the rate of photosynthesis decreases which leads to the lower production of oxygen. The rate of photosynthesis affected by the reactants available to it. If Carbondioxide is available in large amount more photosynthesis occurs that leads to more production of glucose as well as oxygen. So we can conclude that lack of Carbondioxide results in lower production of oxygen in the process of photosynthesis.

One old strand that came back together after replication and one completely new strand that was just assembled
Two completely new strands of DNA built from the lagging strand
Two strands of DNA that are joined, running antiparallel
Two strands of DNA that each contain one strand of the original DNA molecule
The immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.
Meiosis is a reductional cell division by which a cell produces four daughter cells with half of the chromosomes.
Meiosis is preceded by a stage called interphase in which DNA is replicated. The phase of the interphase in which genetic material is duplicated is known as Synthesis (S) phase.
During DNA replication, a new DNA molecule consists of one original DNA strand bound to one strand of newly synthesized DNA.
It is for that reason that DNA replication is said to be semiconservative.
In conclusion, the immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.

Answer:
Asexual reproduction.
Explanation:
The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.
The E-site A) is found on the RNA polymerase enzyme. B) is responsible for the release of the tRNA. C) is found on the 35S polysome. D) is the aminoacyl site on the ribosome. E) is another name for anticodon.
Answer:
B) is responsible for the release of the tRNA.
Explanation:
A transfer ribonucleic acid (tRNA) is an RNA molecule that connects a particular triplet of nucleotides or 'codon' of a messenger RNA (mRNA) to a particular amino acid during protein synthesis (translation) in the ribosomes. In a cell, tRNAs can be found in three different forms: aminoacyl-tRNAs, peptidyl-tRNAs, or deacylated tRNAs. Moreover, during translation, the tRNA binds to the ribosome at three different sites. The E-site (E for exit) refers to the final binding site for deacylated tRNAs in the ribosomes (i.e., before their dissociation from the ribosomes) during protein synthesis. The first binding site for tRNA in the ribosome is the A-site (A for aminoacyl), while the second binding site is called P-site (P for peptidyl). These three sites are oriented in inverse sense (5' to 3' E-P-A) with respect to the mRNA.

Passage
People traveling to an island accidentally introduced mice into an ecosystem that previously had no mice. The population of mice quickly grew out of control. It started harming populations of native plants and birds. Scientists offered two solutions. One was to introduce cats to the island. The cats could hunt and eat the mice. The other suggestion was to introduce a disease that could infect the mice and reduce their population.
Answer:
Cat.
Explanation:
Introduction of cat can control the population of mice on the island more effectively as compared to the introduction of disease because the introduction of disease can cause damage to other population of that environment that adversely affected the ecosystem. Cat feeds on mice that act as a controlling agent in this ecosystem that will leads to decrease as well as controls the population from increasing in order to cause damage to the environment.
