You will be the expert: Imagine you are teaching a class on controlling microbial growth in the environment. To test your students, you will present them with a scenario including a site and some probably microbes present. They must design a strategy to eliminate harmful microbes from the area.
1A. Come up with a scenario/situation including a site and some probable microbes present.
1B. Come up with possible solution/analysis to that scenario/situation in order to eleminate harmful microbes.

Answers

Answer 1

Answer:

A possible scenario would be many rusty pipes with abundant soil in an abandoned area or house.

The probable microorganism would be clostritium tetani, which causes tetanus disease.

This clostridium is eliminated once the oxidized surfaces are exterilized, eliminated and cleaned with disinfectants.

In addition, it could be sprayed with disinfectant on the ground to kill the presence of possible spores of this bacterium.

Explanation:

Clostridium tetani is a bacterium that affects the central and peripheral nervous systems of humans.

Today there is a vaccine for this bacterium, which is called tetanus and is administered against a possible accident, surgical act or risk of having been inoculated with the bacteria.

The current tetanus vaccine has a longevity of 10 years in the human organism, once this period has passed, the booster should be given.

This bacterium coexists with other microorganisms in this environment with accumulations of soil and rust, which the most dangerous would be fungi (they trigger deep mycosis). An example of these fungi is: histoplasma capsulatum, responsible for generating histoplasmosis.

Answer 2

The scenario or situation including a site and some probable microbes present would be a controlled Laboratory.

The possible solution or analysis to that scenario in order to eliminate harmful microbes is fumigation.

Identification of microbes is critical in determining which microbial removal strategies will be used in a site.

The scenario or situation including a site and some probable microbes present would be a controlled Laboratory where microbes are isolated from the site via cultured methods. When carrying out microbial culture, the culture plates usually support the growth of a wide range of microorganisms. As a result, biochemical approaches may be used to distinguish one microbial population species from another. They may exist in various species of fungi, viruses, bacteria, protozoa, etc.

The elimination of microbes is dependant on the size of the area being analyzed. This is done by the application of formaldehyde to the area. Other methods include alcohol sterilization and heat sterilization for cleaning and sanitizing surfaces of the laboratory and equipment respectively.

Describe Dr. Vellend's unifying theory of ecological communities (the factors that determine community structure). Where do concepts like competition, predation, habitat suitability, disease and parasitism, and disturbance (most of what we covered this semester) fit into his theory

Answers

Answer and Explanation:

Community ecology is a discipline that studies the organism's communities and the manner in which populations of species interact with each other within a particular habitat. Mark Vellend is an eco-evolutionist that developed a theoretical framework of ecological communities from a unified functional perspective. This theory is based on four forces of evolutionary biology: selection, drift, dispersal and speciation. This theory is used to explain how species interactions including parasitism, competition and predation may influence population fluctuations. On the other hand, this theoretical framework can also be used to understand how colonization, disturbance and habitat suitability components alter the dynamics of interacting species.

Answer:

corrugated cardboard tube - digestive tract

irregular surfaces on the corrugated tube - villi

pump - heart

Plastic tubing - blood vessels

Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

The original name for Asian Homo erectus was Group of answer choices Homo rudolfensis. Australopithecus. Paranthropus. Pithecanthropus.

Answers

Answer: Pithecanthropus erectus.

Explanation:

Between 1891 and 1892 Eugène Dubois believed he had found the "missing link", hypothesized by Ernst Haeckel, when he discovered some loose teeth, a skull cap and a femur - very similar to that of modern man - in the excavations he was carrying out in Trinil, located on the island of Java, Indonesia. Homo erectus erectus was the first specimen of Homo erectus to be discovered.  Dubois first named it Anthropopithecus erectus and then renamed it Pithecanthropus erectus. The name Homo erectus means in Latin "erect man", wich means, "standing man", whereas Pithecantropus erectus means "standing ape-man".

So, Dubois published these findings as Pithecanthropus erectus in 1894, more popularly known as "Java Man" or "Trinil Man". In the 1930s the German palaeontologist Ralpf von Koenigswald obtained new fossils, both from Trinil and from new locations such as Sangiran and in 1938 von Koenigswald identified a magnificent Sangiran skull as "Pithecanthropus". It was not until 1940 that Mayr attributed all these remains to the genus Homo (Homo erectus erectus).

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.

Answers

Answer:

C. facilitates the absorption of vitamin B12.

Explanation:

The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.

The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.

Explanation:

An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.

QUICKLY! The chemical reaction equation of photosyntesis is shown here: What information is not given in this equation. It does not show if the reaction is reversible. It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.

Answers

Answer:

C: It does not show that photosynthesis consists of many separate steps.

Explanation:

Photosynthesis is a unique process carried out by the cells of autotrophic organisms. It is the process whereby they synthesize their own food in form of sugars (glucose) in the presence of sunlight. Ideally, the photosynthetic process makes use of carbon dioxide (C02) and water (H20) in the presence of light energy (from sun) to produce glucose sugar (C6H12O6) and oxygen (02). The general photosynthetic equation is as follows:

6CO2 + 6H20 + light → C6H12O6 + 6O2

However, the process is not as simple as portrayed as it involves many separate steps that collectively forms the photosynthetic product (glucose). Photosynthesis occurs in two major stages namely: light stage and light independent stage, which in turn consists of series of reactions that forms the products.

Therefore, the equation attached to this question describes photosynthesis but It does not show that photosynthesis consists of many separate steps.

Answer:

C: It does not show that photosynthesis consists of many separate steps.

HEEELLLPPP PLSS!!! Compare and contrast open, closed, and isolated systems. Be sure to discuss the exchange of energy and exchange of matter, and provide at least one example of each.

Answers

Answer:

See the answer below

Explanation:

An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.

A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.

An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.

Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

You have been assigned a DNA stretch. What is the complementary strand when you replicate the template

Answers

Answer:

The complementary strands of a DNA are read in the opposite direction to one another

Explanation:

A DNA strand/stretch can be represented with a number of bases. The bases in a DNA strand are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). The Adenine can bind to Thymine (and vice-versa) while the Guanine can bind to Cytosine (and vice versa). These bonded bases are called "base pairs".

Complementary DNA strands are read in opposite direction to one another. Each end of a DNA strand is either a 5' end or a 3' end. Hence, if one strand runs from the 5' to 3' end, the complementary strand will run from the 3' to 5'. Thus, they are represented "on paper" the way they run.

For example,

If the DNA strand assigned is AGTCTAG running 5' to 3', the complementary strand will be CTAGACT (starting from the 3' end) and NOT TCAGATC (which starts from the 5' end)
