In your biology career, you may come across people attempting to use the Second Law of Thermodynamics to discredit the idea of evolution. Their argument goes something like this: The theory of evolution says that life evolved from smaller inorganic molecules to larger organic molecules to simple one-celled organisms to more complex multicellular organisms, moving towards more complexity and organization. But the Second Law of Thermodynamics says that entropy always increases, with everything moving towards increasing disorder. Therefore, if the Second Law is correct, then evolution is impossible. How would you respond to this argument
Answer:
Evolutionary ideas do not contradict the thermodynamic laws, these ideas explain how descent with modification enables the organisms to have enhanced metabolic responses to fight against entropy
Explanation:
Organisms fight against entropy to maintain order within their cells and thus continue life. The debate about the association between the Second Law of Thermodynamics and evolutionary ideas emerged in 1900. During this period, it has been proposed that both ideas were contradictory, since evolution decreases entropy, while the second law states that systems increase entropy over time. However, the evolution does not contradict this law, because evolutionary ideas indicate the mode by which the organisms evolve to fight against entropy (for example, by enhancing enzymes responsible for protein degradation), while the Second Law of Thermodynamics literally states that the total amount of entropy of the whole system increases over time.

Explanation:
In neuroscience, depolarization is an "all or nothing" response; what does that
mean?
The neuron's intracellular charge must get more negative to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire
The neuron will either accept all signals, or none of the signals received. If the
neuron is ready to receive signals, then it automatically depolarizes and sends the
signals to the next neuron.
The neuron's intracellular charge must get more positive to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire
The neuron decides how much of the electochemical signals to send to the next
neuron; all or nothing
Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

Which of the following is true of the Celsius scale A.) 212° is the boiling point of water b.) 0° is absolute zero c.) 0 degrees is the freezing point of water or D .) 32° is the freezing point of water
Answer:
The correct answer is C., or ¨0 degrees is the freezing point of water¨.
0 degrees is the freezing point of water is true about the Celsius Scale. Therefore, option (C) is correct.
Water freezes at "zero degrees" on the Celsius scale. Under ordinary climatic conditions, water's freezing point is 0 degrees Celsius and its boiling point is 100 degrees Celsius. Many countries use this scale to measure temperature.
However, the Fahrenheit scale, used mostly in the US, has different freezing and boiling points for water. Water freezes at 32 degrees Fahrenheit and boils at 212. Therefore, option (C) 0 degrees is the freezing point of water is correct.

Earth is currently in a state of climate change because average global temperatures are slowly but steadily increasing. If this trend continues, what changes would you expect to see in the cicada life cycle? Use information from the article to support your argument
Answer: Cicadas will emerge from underground earlier in the year. Based on current patterns, they emerge earlier in the south than in the north because it’s warmer in the south, so the soil warms sooner. If global temperatures increase around the world, cicadas will emerge from the ground in all areas earlier than expected.

what are 3 modifications to pyruvate in the intermediate phase
Answer:
Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.

In eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl two-carbon molecule attached to Coenzyme A—producing an t, N, A, D, H, end text and releasing one carbon dioxide molecule in the process. Acetyl C, o, A, end text acts as fuel for the citric acid cycle in the next stage of cellular respiration.
Pyruvate oxidation steps
Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.
In the matrix, pyruvate is modified in a series of steps:
More detailed diagram of the mechanism of pyruvate oxidation.
1. A carboxyl group is removed from pyruvate and released as carbon dioxide.
2. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.
3. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.

Step 1. A carboxyl group is snipped off of pyruvate and released as a molecule of carbon dioxide, leaving behind a two-carbon molecule.
Step 2. The two-carbon molecule from step 1 is oxidized, and the electrons lost in the oxidation are picked up 2 \text{NADH}NADHstart text, N, A, D, H, end text are generated from \text{NAD}^+NAD
Step 3. The oxidized two-carbon molecule—an acetyl group, highlighted in green—is attached to Coenzyme A (\text{CoA}CoAstart text, C, o, A, end text), an organic molecule derived from vitamin B5, to form acetyl \text{CoA}CoAstart text, C, o, A, end text. Acetyl \text{CoA}CoAstart text, C, o, A, end text is sometimes called a carrier molecule, and its job here is to carry the acetyl group to the citric acid cycle.
The steps above are carried out by a large enzyme complex called the pyruvate dehydrogenase complex, which consists of three interconnected enzymes and includes over 60 subunits. At a couple of stages, the reaction intermediates actually form covalent bonds to the enzyme complex—or, more specifically, to its cofactors.

This is actually not as complicated as it may seem. Wind tunnels are a way that scientists and students can see how wind can affect rockets. The Wright brothers used a wind tunnel to test there model planes. The reason it has limitations is there is no wind is space because there is no gravity which means there is no particles that make up weather and wind. Wind tunnels help us know how the rocket will perform on the earth, but not in space.

Assume cube B was broken into many irregularly shaped pieces. Compared to the density of the entire cube, the density of one of the pieces would be
Answer:The same
Explanation: even thought the cube is split in many pieces the density stays the same
Because breaking the thing into pieces divides the mass and volume by the same factor, the density does not change. Additionally, regardless of a substance's size, its density is constant.
What is density relation with shape of object?An intensive property is density. This implies that the density of the substance will remain constant regardless of the shape, size, or amount of the thing.
Each component of the thing would have the same density even if you divided it into a million pieces.
For instance, despite the cube being divided into numerous parts, its density remains constant.
In a solid, the atoms or molecules are typically arranged in an orderly or occasionally crystalline structure,
Whereas in a liquid, they are free to move around with little restrictions. Because of this, the solid has a higher density.
Therefore, the density of one of the pieces is remained unchanged.
