An amoeba is much less complex than a fruit fly; however the amoeba has a much larger genome (c-value). What is the best overall explanation for this paradox?
The amoeba has a much larger genome (C-value) because A large percentage of eukaryotic genomes is non-coding DNA, the amoeba has much more non-coding DNA than the fruit fly.
The amount of DNA in an organism's haploid genome is measured by the C-value. It varies greatly, often rising in C-value as organism complexity increases—from prokaryotes to invertebrates, vertebrates, and plants.The so-called C-Value Paradox refers to the finding that genome size does not always rise in proportion to an organism's apparent level of complexity.In comparison to prokaryotes (organisms without a nucleus), such as bacteria, eukaryotes, or species having a nucleus to hold their genetic material (DNA), do have larger genomes. Only 4 million base pairs make up the best friend of microbiologists, E. coli. On the other hand, the fly, Drosophila Melanogaster, has 140 million base pairs.

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of:______
a. protein.
b. glucose.
c. thiamin.
d. riboflavin.
Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..
The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.
A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.
Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.

Which statement BEST describes how greenhouse gasses act as natural insulators in the Earth's system?
Hi there, your answer is below.
The gases absorb and emit a part of the heat reflected by the Earth's surface.
Solar radiation will pass through the atmosphere first in the greenhouse effect. Some of them will get through and touch the surface of the planet. Long-wave thermal radiation, which is what the greenhouse gases will absorb, will be produced when some of the energy that strikes the Earth's surface is transformed. They are returned to the Earth via greenhouse gases.
What are greenhouse gases, and why do they affect our environment?The surface of the Earth would be much colder and have a "snowball Earth" if it weren't for the impact of greenhouse gases, primarily water vapor, carbon dioxide, and methane.
Because the greenhouse gases are generally transparent to the sun's incoming radiation, which is mostly in the visible light region of the spectrum, the greenhouse effect is able to take place. In contrast, the majority of the radiation that the Earth emits is in the infrared region of the spectrum, which is absorbed by greenhouse gases. Some of the radiation from these gases is redirected to the earth when it is later released. This traps it, warming the planet's surface in the process. The average temperature of the Earth would be -14 degrees Celsius without greenhouse gases.
Greenhouse gases have acted to even out temperature changes over Earth's history. Huge woods have thrived when the Earth experienced warmer times, as the Carboniferous epoch. These have taken in carbon dioxide from the air, storing the resultant carbon in the form of coal deposits underground. After a certain amount of carbon has been stored, the atmospheric concentration of carbon dioxide falls to very low levels, and the warming effect is eliminated. The trees perish as the globe cools. Currently, plants are no longer removing carbon dioxide from the atmosphere, while volcanoes are still adding carbon dioxide to the atmosphere. The increase in carbon dioxide causes a rise in global warming. We are now recuperating from the last glacier, which ended roughly 10,000 years ago, during a mild time. In the past 120,000 years, the previous warm era peaked.
The ability of carbon dioxide to boost plant development is another crucial effect. Without the impact of the increased carbon dioxide concentration on crops, it is improbable that the Earth could support the 7 billion people that inhabit it now.
The amount of carbon stored in the atmosphere is rather tiny. There are currently 800 billion tons of carbon in it. But only approximately a quarter of this, or 210 billion tons, of the carbon gets recycled each year by plants and the seas. Consequently, the two-year half life of carbon in the atmosphere is rather short. Because there is such a tiny atmospheric carbon storage, people have a significant impact. Burning fossil fuels only adds roughly 9 billion tons annually. But throughout my lifetime, the concentration has increased by 30%, from around 300 parts per million in 1947 to 410 parts per million now, as a result of this modest increment each year. As a result, there has been a little but considerable increase in surface temperature as well as rising sea levels due to ice cap melting. Although the increase in sea levels over the past 70 years has only been around 9 inches, it is rising, and because so many people live near the coasts, we are susceptible.
Because the atmospheric carbon storage is so limited, it is possible to lower atmospheric carbon and prevent flooding in our coastal communities, for example by fertilizing the seas to improve their capacity to absorb carbon dioxide.

Eddie
Some bacteria have been found to have much higher rates of mutation than other members of their population; they are termed "mutators." What do you think is the most likely reason for their higher rates of mutation?
Their DNA polymerase has compromised 3' to 5' exonuclease function.
PolymeraseAn enzyme that builds lengthy nucleic acid or polymer chains is called a polymerase. Using base-pairing interactions to copy a DNA template strand, DNA polymerase and RNA polymerase build DNA and RNA molecules, respectively, while half ladder replication builds DNA molecules.
For the polymerase chain reaction, a crucial molecular biology method, the thermophilic bacteria Thermus aquaticus' DNA polymerase is used. Template dependence or independence are two possible states for a polymerase. Template independent polymerase examples include poly-A-polymerase.

Using the organisms you identified in part B, create a food web for the ecosystem you chose. Use this sample food web for reference, although your food web will contain fewer organisms. Note that your food web does not have to include images, but you may include them if you choose. However, be sure to include arrows to indicate the direction of energy flow in your food web. Design your food web using any method listed below: Use drawing or flowchart-building tools in a word-processing program. Hand draw your food web, and then take a picture of it. Use a graphic-design program. Using the Insert Image button, insert an image of your food web in the answer space.
The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, caw, rabbit, bird, eagle, mountainlion, and fungi.
Note: Since you did not detailed the organisms you identified in part B, I will define what a trophic web is, and propose an example for you to understand.
What is a trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Example.
To make the trophic web, first, you need to define the position of each of the organisms on the web.
Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.
Consumers → heterotroph
⇒ Herbivores → These are the animals that feed on any part of the plants → Let us say we have a caw, a rabbit, and a bird.
⇒ Carnivores → These are the animals that feed on herbivores → Let us say a mountain lion and an eagle.
Decomposer → detritivorous organisms that take energy from dead matter → Fungi
So, our organisms are
plants, caw, rabbit, bird, mountain lion, and eagleFungiPlants directly provide energy to the caw, the rabbit, and the bird.
Plant >> Caw, Rabbit, Bird
The eagle takes energy from the rabbit and the bird.Rabbit and Bird >> Eagle

The effect of sympathetic nervous system stimulation on the heart is to increase heart rate and myocardial contractility.
In the sympathetic nervous system (SNS), as the sympathetic stimulation increases, the heart rate also decreases along with the force of contraction.
The heart rate increases because of the release of hormones catecholamines - epinephrine and norepinephrine whereas the force of contraction increases because of a higher end-systolic volume [ESV] which requires a forceful heart contraction to pump more blood out of the ventricle which will decrease the ESV value.
The end-systolic volume [ESV] is the amount of blood that remains in a ventricle after a contraction (systole) which is to be maintained at around 50 mL of blood.
