You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.

Answers

Answer 1

Answer:

To determine the effect of toxin binding, you perform a Competitive Binding Experiment

Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

When an electric light is turned on, the amount of light energy released by the lightbulb is less than the amount of electrical energy going into the lightbulb. Which statement best explains this?

Question 4 options:

Some of the electrical energy is destroyed.


Some of the electrical energy is changed into heat energy.


Some of the electrical energy stays in the wire.


All of the electrical energy is destroyed.

Answers

Answer:

Some of the electrical energy is destroyed.

Explanation:

some of the electrical energy is destroyed because If the excess energy goes beyond the tolerance of the devices, they will overheat and/or burn (cause damage). ... If there is no interest in saving the extra energy, it can be "dumped" into an appropriate load and converted to heat.

When a lightbulb burns out, then that is when all of the electrical energy got desroyed, and that is why it happens over time

The statement that best explains this is some electrical energy is destroyed. The correct option is A.

What is electrical energy?

Electrical energy is kinetic energy generated by moving electric charges. The amount of energy relies on the charge's speed; the faster it moves, the more electrical energy it carries.

Some electrical energy is destroyed because if the extra energy exceeds the devices' tolerance, they will overheat and/or burn (causing damage). If there is no desire to save the excess energy, it can be “dumped” onto a suitable load and transformed into heat.

When a lightbulb burns out, all of the electrical energy is destroyed, which is why it happens over time.

Therefore, the correct option is A. Some electrical energy is destroyed.

similarities between living species and fossils have been discovered and lead scientists to believe that they share what?

Answers

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Gametes, which are sex cells, carry the alleles. Why must a gamete carry one allele (represented by a letter) from each gene? Meaning, why can’t a gamete carry an “hh” instead of an “hs” or an “Hh” instead of a “HS?”

Answers

Answer:

Due to the law of independent assortment

Explanation:

In diploid species like humans, all somatic (body) cells have two complete sets of chromosomes, one chromosome inherited from the maternal gamete and one chromosome inherited from the paternal gamete. Each one of the homologous chromosomes contains one copy of each gene, or allele, such that one allele is inherited from each parent. According to the law of independent assortment, maternal and paternal chromosomes are independently assorted during meiosis, which means that different genes localized on different chromosomes are randomly distributed into gametes. In consequence, alleles of different genes are transmitted from parents to offspring independently of one another.

How does energy move through living systems?

A certain regulatory gene is involved in controlling the expression of other genes. In studying this regulatory gene, a scientist discovers that it encodes for an enzyme that causes histone deacetylase (the removal of acetyl groups from histone tails). Based on this information, how would you predict that this enzyme regulates gene expression

Answers

Answer:

by an epigenetic mechanism

Explanation:  

Epigenetics can be defined as the study of mitotically heritable gene expression changes that do not involve alterations in the DNA sequence. There are three different epigenetic modifications that work together either to activate or repress gene expression: DNA methylation, histone modifications (e.g., methylation, acetylation, phosphorylation, etc) and regulatory non-coding RNAs (e.g., long non-coding RNAs, microRNAs, piwi-RNAs, etc). Deacetylases are enzymes that play roles in epigenetic gene regulation by removing acetyl groups from lysine (K) residues located at the N-terminal end of histones H3 and H4. Histone deacetylation modifies the structure of the chromatin, thereby activating or suppressing gene expression in a context-dependent manner.

Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside, how can the candy bar sit still on the shelf in the grocery store

Answers

Answer:

Energy is stored as potential energy

Explanation:

Candy bars are primarily made of glucose (and other types of sugars), which contain many covalent bonds that store potential energy. The reason why a candy bar can sit still on the shelf is because covalent bonds are very stable. However, when you eat the candy bar, your body has enzymes that can metabolize the candy, breaking down the covalent bonds and releasing all that "trapped" energy inside.

The yeast used to make beer can perform aerobic respiration or alcoholic fermentation. When O2 is available, yeast perform aerobic respiration, and when O2 is not available, yeast perform alcoholic fermentation. What is the advantage of aerobic respiration

Answers

Answer:

Aerobic respiration generates a high amount of energy compared to anaerobic respiration.

Explanation:

Yeast is a unicellular organism that belongs to the kingdom FUNGI. Yeast is a phenomenal organism being that it is capable of both aerobic respiration and anaerobic respiration depending on whether there is availability or not of oxygen.

Yeast undergoes a type of anaerobic respiration called FERMENTATION in the absence of oxygen but when oxygen is present, it undergoes aerobic respiration. Note that aerobic respiration, which includes glycolysis, Krebs cycle, and oxidative phosphorylation, produces the highest amount of energy in form of ATP. This amount ranges from 32-34 ATP molecules. This is the major reason why aerobic respiration is advantageous over the anaerobic respiration.

Potassium metal reacts vigorously with all the halogens to form potassium halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively potassium(I) bromide, KF, potassium(I) chloride, KCl, potassium(I) bromide, KBr, and potassium(I) iodide, KI.

Rubidium is a soft, white metal that reacts with water similarly to sodium and potassium, but the reaction is much more violently exothermic.

What is a chemical reaction?

When one or more chemicals are converted into one or more other chemicals, a chemical reaction occurs.

A chemical reaction is a practice that reverts one or even more substances, renowned as reactants, to one or even more various compounds, widely recognized as products.

Chemical elements or compounds are examples of substances.

Living things (cells, animals, humans, and insects) use chemical reactions to grow, develop, reproduce, and adapt.

Combination, decomposition, single-replacement, double-replacement, and combustion are the five basic types of chemical reactions.

Analyzing the reactants and products of a specific reaction will allow you to categorize it.

Rubidium is basically a soft, white metal that reacts with water in the same way that sodium as well as potassium do, but the reaction is much more exothermic.

Thus, rubidium and sodium are the two other elements that react the same way in a chemical reaction as potassium.
