Answer:

A working hypothesis is that signaling efficiency/specificity is determined in part by proteins found in the receptor's microenvironment, which together with R, G, and E contribute to the formation of a signal transduction complex at the cytoplasmic face of the receptor.

Answer: In principle, to minimise heat transfer through the building envelope the building shape should be as compact as possible,tending toward a cube.

Explanation:

A building's design should be compact and rounded to reduce heat loss through the surface. The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

By lowering the building's surface area, this design limits the region where heat may escape from the structure. The surface area to volume ratio should be taken into account while trying to reduce heat loss.

A building that is compact and rounded, such a cylinder or dome, has a lower surface area-to-volume ratio than a building that is rectangular or square and has the same volume. Accordingly, less heat is lost from the building's surface in comparison to the heat that is kept inside the structure.

Additionally, a compact, rounded building will have fewer corners and edges, which are vulnerable to heat loss. Additionally, the structure can be angled to receive as much sun exposure as possible, which can add to the building's heating capacity during the winter.

Therefore, a building's design should be compact and rounded to reduce heat loss through the surface.

Calcium is very important to the organism, and different factors influence its absorption. Pregnancy, Infancy, Vitamine D increase calcium absorption. Oxalic acid, phytic acids, and being over 70 years old decreases absorption

------------------------------------------

Calcium is a highly significant mineral for the appropriate development and functioning of the organism.

Different factors influence the mineral absorption, favoring it or limiting it.

Among the factors that might favor calcium absorption, we can mention

In the second and third trimesters of pregnancy, calcium absorption is the greatest. The intestinal absorption of calcium in women during this period increases to meet different demands. Calciotropic hormones are involved in the process.

Vitamine D is one of the principal factors involved in calcium regulation. Vitamine D helps to double calcium absorption through the thin intestine.

During infancy, the body is growing, bones are developing, and the body needs to consume a high amount of calcium to accomplish these functions.

Calcium is a baseline mineral to provide children while growing, especially in their first periods of life.

Among the factors that limit calcium absorption, we can mention

Elder people consume less food, and together with food consumption decrease, a less amount of necessary mineral is consumed.

With aging, calcium absorption decreases approximately 20% in the intestine.

Many substances, together with ingested calcium, form compounds that impede mineral absorption through the small intestine.  

So in the presence of substances such as oxalic acid and phytic acid, calcium absorption is limited.

It is recommended not to consume food rich in calcium and food rich in these other substances simultaneously.

Answer:

The particular structure of the influenza virus genome and function of its viral proteins enable antigenic drift and antigenic shift.

Answer:

Between worldwide outbreaks, known as pandemics, influenza viruses undergo constant, rapid evolution (a process called antigenic drift ), which is driven by mutations in the genes encoding antigen proteins.

Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains. The term is often applied specifically to influenza, as that is the best-known example, but the process is also known to occur with other viruses, such as visna virus in sheep. Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change.

Answer:

An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.

To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally

A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem

An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

What is the function of enzymes in a living system?

Enzymes speed up metabolic reactions necessary for life. Without them, certain vital processes would not take place and the body would be unable to function.

Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments?

In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example of such an enzyme is pepsin.

There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer.

More hydrogen peroxide will be broken down in the summer…show more content…

Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.  

Sulfuric acid - was used to stop the reaction with catalase and hydrogen peroxide.  It denatured the enzyme (catalase) and halted the reaction so the amount of hydrogen peroxide decomposed could be measured.  

Before performing part D of the experiment, why was it necessary to establish a baseline?

The baseline is a control and shows the amount of decomposed hydrogen peroxide in the initial sample.  

You may have observed the reaction of naturally occurring catalase in tissue from either liver or potato. Design an experiment to determine if the amount of catalase varies from tissue to tissue (e.g. 200 g of the liver compared to 200 g of potato).  

Put the 100 g of potato in 1 petri dish and 100 g of the liver in another petri dish. Then put equal amounts of hydrogen peroxide for an equal period of time in both dishes. Drain the dishes and titrate them with potassium permanganate simultaneously. The numbers can now be compared using the steps in the sample calculation above in the lab report. In order to compare perform a potassium permanganate titration on pure hydrogen peroxide.  

Of the thousands of enzymes known, there is a family of enzymes called proteases that catalyze a reaction of breaking down proteins. What do you think would happen if you added a protease to your sample of catalase before proceeding with your experiment?  

The catalase would be broken

D. It is warming faster than previous natural cycles.

The movement of alleles into a population is called gene flow. The most likely explanation for why this trait does not entirely spread in the population is 'outside alleles enter the population through gene flow'.

Gene flow is caused by the migration and further reproduction of individuals in the population, or the transport of gametes from one population to another (e.g., the transport of pollen by pollinating bees).

Gene flow is an evolutionary force capable of modifying allele frequencies in a population.

In this case, despite the evolutionary advantage that the mutated allele confers to the butterflies, the frequency of this allele can not reach 100% due to the continued introduction of alleles from other populations (i.e., due to gene flow).
