Explanation:
We have attached a figure that shows the diagram of the given equation.
We need to find how many angles are alternate exterior angles with angle 5?
We know that an exterior angle is the angle that is made outside of the shape and an alternate angle is the angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.

History has demonstrated that the techniques employed in this laboratory exercise often overestimate an individual's actual resting tidal volume. List some reasons why these laboratory techniques might produce abnormally high values for resting tidal volume.
Answer:
See below
Explanation:
One possible reason here could be the fact that since the person is being watched while doing this exercise, they might tend to breather deeper than they normally do. Secondly, it may also be because the person is trying to make up for the spit filter and flow meter by breathing harder/sharper than they normally would.
Why were the advent of metagenomics, and the application of molecular techniques such as single-cell and next-generation sequencing, important for defining a microbial relationship
Answer:
Based on novel approaches, it has been seen that symbiotic associations prevails between a host and one to thousands of more microbes, which challenges the previous meaning of symbiotic association as one that takes place between the host and a single microbe. It was considered previously that symbiotic association’s takes place only between the pair of single microbe and host.
However, newer approaches has revealed that such kind of association can take place between one microbe and many other hosts. A symbiotic association can take place between microbe-microbe, plants-plants, microbe-plants, and others. However, symbiotic association has never been found to take place between a bacteria and animal host. The symbiotic associations are always not parasitic.

active transport occurs in cells for example when Na-k pump is at work.Any process that involves active transport most often involves the
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.

Explanation:
ions but you do not want to increase the volume of the blood by reabsorbing large amounts of water from the filtrate. Assuming the aldosterone and ADH are both present, how would you adjust the hormones to accomplish the task
Answer:
Aldosterone and ADH are part of the renin angiotensin aldosterone system, this system is a system regulated by the kidney and lungs to be able to raise blood pressure.
Explanation:
This system is a retainer of liquids and water, to increase the blood volume of our body, in this way arterial hypotension is compensated.
Another mechanism with which blood volume can be increased is with the stimulation of thirst, and the need to ingest a liquid because of the dry mouth that our central nervous system perceives.
Both mechanisms prevent hypotension and dehydration.

In the wild, various sperm and egg cells must navigate a complex environment to complete fertilization. There are mechanisms in place at the molecular level to guard against interspecies fertilization, even between very closely related species. Some of these mechanisms involve lock and key functions of interacting proteins. These molecules most likely regulate which type of reproductive isolation mechanism? Please explain.
Answer:
pre-zygotic reproductive isolation
Explanation:
The molecules regulate the pre-zygotic reproductive isolation mechanism.
Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms.
Some of these processes act to prevent fertilization or the formation of zygotes between organisms that are not of the same species (pre-zygotic mechanisms) while others ensure that the product of fertilization is invalid in case the former fails (post-zygotic mechanisms).
Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.
The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.

If a splinter of wood were to enter the skin and introduce microorganisms to that site, what specific early and late events of inflammation would respond to that newly infected tissue
Answer:
If a splinter of wood enters the skin and introduces microorganisms to the site the body would first release chemical mediators like histamine then cause vasoconstriction. Platelets work to make a blood clot then neutrophils come in and vacillation occurs. This causes redness, warmth, swelling and pain. Edema and pus formation occurs therefore the neutrophils work to rid the area of cell debris and pathogens. Later the lymphocytes and macrophages will finish the job of the neutrophils and scar tissue is formed to repair the damaged tissue.
Explanation:
In Drosophila, the genes for body coloration and eye size are on different chromosomes. Normal-colored bodies are dominant to ebony-colored (very dark) bodies, and normal-sized eyes are dominant to eyelessness. Line A is true breeding for normal bodies and normal eyes, whereas line B is true breeding for ebony bodies and eyelessness. From an F 2 cross between lines A and B, 800 flies are scored. How many F 2 flies are expected to have normal body color and to be eyeless
Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.

What substance are the bacteria (microorganisms) breaking down in the digestive system of cattle? Describe the digestion of this substance.
Answer:
The Bacteria or microorganisms are present in the rumen of cattle that aid in the digestion of cellulose and grains in the digestive system of cattle.
The process of digestion of cellulose by bacteria in cattle is anaerobic digestion and includes two steps – the production of the required enzymes and the fermentation.
In the fisrt step of production of enzyme, the microbes or bacteria are found in the first chamber of the stomach. These bacterias or microbes releases several enzymes that helps in splitting the cellulose into smaller carbs such as glucose.
These smaller carbs are the move to thrd chamber of the stomach and fermented. the required nutrients are absorbed. The digested food then finally reached at fourth chamber (acidic part), where the remained food is digested and passes to the small and large intestines.
How are the current and resistance related when the voltage of a circuit is constant?
The current doubles when the resistance doubles because they are directly proportional.
The current doubles when the resistance doubles because they are inversely proportional.
The current is cut in half when the resistance doubles because they are directly proportional.
O The current is cut in half when the resistance doubles because they are inversely proportional.
Answer:
The current is cut in half when the resistance doubles because they are inversely proportional.
Explanation:
Ohm's law states that the electrical current (I) flowing in a circuit is proportional to the voltage (V) and inversely proportional to the resistance (R).
I = V/R
Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed.

B)to create interesting looking pets.
C) the florescent cells can help track the movement of cells.
D) to create light in a dark laboratory.
The correct answer is C) the fluorescent cells can help track the movement of cells.
Explanation:
In the last years, geneticists and scientists created animals that glow in the dark by inserting a Green Fluorescent Protein or GFP gene found in some species of jellyfish. This protein was used in animals such as rabbits, rats, and even chickens. One of the key reasons for this is that by inserting fluorescence scientists can better observe the development and movement of cells. This includes analyzing cells reproduction and growing in embryos of "glowing" animals or inserting the protein in specific cells or organs in an organism to observe how these change or move. Thus, the purpose of studying fluorescent rabbits is that "the fluorescent cells can help track the movement of cells".

A karyotype shows that a child has Klinefelter syndrome (47,XXY). If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision, in which parent and stage of meiosis did nondisjunction occur?
Answer:
It occurred in the mother and in meiosis II stage
Explanation:
A karyotype shows that a child has Klinefelter syndrome (47,XXY) which involves a male child having an XXY chromosome in which the XX chromosome codes from the mother.
If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision then the nondisjunction occurred in meiosis II because sister chromatids separate during meiosis II and the non separation is the reason for the Klinefelter syndrome.
Approximately how much methane does one cow produce per year? How does the greenhouse gas warming effect of methane compare to carbon dioxide? Describe the organisms that digest and ferment the hay inside of the cow’s stomach? How are scientists reducing the amount of methane released from cows?
Answer:
Cattle and other ruminants are significant producers of the greenhouse gas methane—contributing 37 percent of the methane emissions resulting from human activity. A single cow on average produces between 70 and 120 kg of methane per year and, worldwide, there are about 1.5 billion cattle.
While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. ... As temperatures rise, the relative increase of methane emissions will outpace that of carbon dioxide from these sources, the researchers report.
The cow's rumen is like a large fermentation vat. More than 200 different bacteria and 20 types of protozoa help the cow to utilize fibrous feedstuffs and non-protein nitrogen sources. ... Bacteria adhere to the feed and gradually digest the fermentable material.
“You can probably reduce methane by about 20-25% by altering diet,” he says. One study by researchers at the University of California, Davis, estimated it might be possible to reduce global methane emissions from cows by 15% by changing their diet.

Emily and Zach are two students working in the lab to improve the stability and activity of the newly discovered transport protein BCM1 in eukaryotic cells. While introducing mutations into the protein sequence that were predicted to improve the stability and activity of BCM1 Zach convinced Emily to mutate some of the amino acids in the N-terminal signal peptide region of the protein sequence. Subsequently, they expressed this mutated BCM1 protein in eukaryotic cells and observed very little transport across the membrane via the mutate BCM1 transporter in comparison to the levels of transport that was observed via the unmutated BCM1 transporter. Upon further analysis Emily determined that the reduction in transport across the mutated BCM1 transporter was due to mutations made in the signal peptide region of the BCM1 sequence. Explain to Zach the importance of this signal peptide region and disrupting it would lead to reductions in the BCM1 transporter activity.
Answer:
A mutation in the N-terminal region may alter protein stability
Explanation:
Transport proteins are proteins capable of transporting substances through biological membranes. These proteins are located within cellular membranes where they form channels that allow the movement of substances between the internal and external sides of the membrane. The N-terminus is the first region in the protein that emerges from the ribosome during its synthesis. This region is usually composed of signal peptides consisting of about 30 amino acids required for protein delivery. Moreover, the N-terminal region is also important because it dictates protein degradation by peptidases. Consequently, mutations in the N-terminal region of transport proteins can alter the properties of these proteins, i.e., either by modifying protein stability or by altering protein signaling.
