14. Which of the following is not true regarding when a neuron is at rest?
A. it is not conducting an action potential.
B. more sodium ions (Na+) outside the cell than inside the cell.
C. more potassium ions inside the cell than outside the cell.
D. more sodium ions inside the cell than outside the cell.
Answer: C.
Explanation: The way the pump functions is it intakes 3 sodium ions, and spits out two potassium, so when the neuron is at rest after firing, it has to spit out all the potassium in order to intake the sodium. It will slowly intake more potassium to make up for the deficit but when at rest, the potassium concentration is higher outside the cell.
excluding the proteins that are made by ribosomes in either the mitochondria or chloroplasts, in what cell compartment or organelle are the first 15 amino acids of every protein made? g
The first 15 amino acids of every protein are made in the cytosol of the cell.
Cytosol is a part of the cytoplasm of a cell that does not contain organelles.
It is found in prokaryotic and eukaryotic cells.
The cytosol, also known as intracellular fluid, is a gel-like substance that fills the cell's interior.
It is the primary site for many chemical reactions, as well as cell signaling and protein synthesis, because it includes a high concentration of water and dissolved substances.
Ribosomes are the cell's protein factories, synthesizing proteins using messenger RNA molecules as templates. Ribosomes, including those in mitochondria and chloroplasts, participate in protein synthesis.
Only the first 15 amino acids of every protein are synthesized by ribosomes in the cytosol. The remaining part of the protein is made up of a series of amino acids generated by translation that occurs on ribosomes that are bound to the endoplasmic reticulum.
Therefore, in addition to the cytosol, the rough endoplasmic reticulum is the organelle where the majority of proteins are synthesized.

The pair of ligaments covered by laryngeal epithelium that function in sound production are the vocal cords or vocal folds.
The vocal cords, also known as vocal folds, are a pair of ligaments covered by laryngeal that are located within the larynx, or voice box. They play a critical role in sound production by vibrating when air is passed over them, producing sound waves that can be modified by the muscles of the larynx, mouth, and throat to produce speech and other vocalizations. The vocal cords are composed of layers of muscle, connective tissue, and mucous membrane. They are controlled by several muscles, including the thyroarytenoid muscle, which is responsible for adjusting the tension on the vocal cords to produce different pitches and tones.

Explain how plant life is benefited when microorganisms release carbon dioxide into the soil.
Answer:
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.
A female Komodo dragon (Varanus komodoensis) kept in isolation in a zoo had progeny. Each of the offspring had two identical copies of every gene in its genome. However, the offspring were not identical to one another. Based on your understanding of parthenogenesis and meiosis, generate a hypothesis to explain these observations.
The hypothesis is that the female Komodo dragon reproduced asexually through parthenogenesis, resulting in progeny with two identical copies of every gene in their genome, but still displaying differences due to other genetic factors. This explanation accounts for the observations mentioned in the question.
Based on the observations mentioned, we can generate a hypothesis to explain the situation. The female Komodo dragon in isolation in the zoo most likely underwent a type of asexual reproduction called parthenogenesis. In parthenogenesis, an unfertilized egg develops into an offspring without the need for a male contribution. This process can occur in certain species, including some reptiles.
In the case of the Komodo dragon, the female may have produced eggs through meiosis, a process where the genetic material is halved. However, during meiosis, the chromosomes can sometimes fail to separate properly, resulting in the offspring having two identical copies of each gene in their genome. This phenomenon is known as a "meiotic error" or "polyploidy."
Even though the offspring have identical copies of genes, they may still exhibit genetic variations due to other factors like genetic recombination or mutations that occurred during the process. Therefore, although the offspring share the same genes, they can still differ from one another.
In conclusion, the hypothesis is that the female Komodo dragon reproduced asexually through parthenogenesis, resulting in progeny with two identical copies of every gene in their genome, but still displaying differences due to other genetic factors. This explanation accounts for the observations mentioned in the question.

What kind of mutation is this?
Answer:
What kind of mutation - "simple base substitution" or "point mutation".
New mRNA strand - CUG CCU GCU AAU
Does the mutation affect the protein. - yes because one amino acid is different
Explanation:
Here a point mutation occurs in the gene.
What is Point mutation?A point mutation is said to occur in a genome when a single base pair is added, deleted or changed.
Here due to point mutation only a single base pair has been changed ,thus the amino acid sequence has been changed. This is because due to point mutation in the DNA strand the mRNA produced is also changed so the amino acids coded by the mrna are also changed.
A point mutation exists a genetic mutation where a single nucleotide base exists changed, inserted, or deleted from a DNA or RNA series of an organism's genome. Point mutations have a combination of effects on the downstream protein product—consequences that exist moderately predictable established upon the specifics of the mutation.

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.
In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.

the researcher used the dorsal heat treatment as the control. propose a different treatment that would have been another valid control. college board
If the researcher used dorsal heat treatment as the control, an alternative valid control could be a "sham treatment" or "placebo treatment" where a similar procedure is performed but without the actual heat application.
This would involve mimicking the process of the dorsal heat treatment, including all the steps and handling, but without the actual application of heat. The purpose of using a sham or placebo control is to account for any non-specific effects that may occur due to the treatment procedure itself.
By comparing the effects of the actual treatment (dorsal heat treatment) with the effects of the sham treatment, researchers can assess whether the observed outcomes are specific to the treatment or are simply due to the psychological or physiological responses associated with the procedure.
Using a sham treatment control helps to minimize biases and provides a more accurate evaluation of the effectiveness of the dorsal heat treatment.
It allows for a better understanding of whether any observed changes or effects are attributable to the heat treatment specifically or if they can be attributed to other factors such as the handling, attention, or expectations associated with the procedure.

What is the path or flow of energy in the process of photosynthesis?.
Photosynthesis is a process where plants, algae, and some bacteria use energy from sunlight to convert carbon dioxide and water into sugar, starches, and oxygen gas. In photosynthesis, the path or flow of energy follows the given steps: 1. Light energy from the sun enters the organism.
2. The light energy is then absorbed by the green pigments, such as chlorophyll, found in the chloroplasts of plant cells.
3. This light energy is converted into chemical energy. The energy is used to synthesize ATP (Adenosine Triphosphate) and NADPH (Nicotinamide Adenine Dinucleotide Phosphate). These two energy-rich compounds are used in the second stage of photosynthesis, which is called the Calvin Cycle.
4. The chemical energy is used in the Calvin cycle to convert carbon dioxide gas (CO2) into glucose (C6H12O6) and other sugars. This process is called carbon fixation, which involves the formation of carbohydrate molecules from carbon dioxide and water.
5. The oxygen gas (O2) produced in photosynthesis is then released into the atmosphere. This completes the cycle, and the energy is then available for use by the plant or other organisms that consume it.

classify these hypothesis about the ocean as falseifiable or non falsifiable
The hypotheses classified according to Falsifiable or Non-Falsifiable are given as follows:
Falsifiable:
Reason: When limestone comes into touch with a weak acid, such as carbonic acid, it erodes. Basalt interacts with ocean water; the silicon tetrahedra in basalt break down, allowing silica into the solution. Given that both erode when they come in contact with seawater, the hypothesis is therefore falsifiable.
"Warm ocean water is more enjoyable to swim in than cool ocean water."Reason: This is inaccurate because, while swimming in warm water boosts metabolism and speed since it is roughly 90 degrees Fahrenheit, swimming in cool water is safer because the bodies of living beings react better to cold water temperatures.
Non-Falsifiable:
"The rugged Panama coastline offers a wonderful experience for fishing enthusiasts."Reason: It is right since the protected water in such regions is a haven for a plethora of red fishes. The mangroves are also near to beaches with lagoons, which are popular fishing spots.
"Shallower tide pools offer much algal growth."Reason: It is right because each high tide feeds nutrients to the algae that live in such regions, allowing a complicated food chain among numerous creatures to refill.
What is a Falsifiable and Non-Falsifiable Hypothesis?A hypothesis or model is said to be falsifiable if an experimental observation can be made that disproves the notion in the issue.
That is, one of the possible results of the intended experiment must be a response that, if received, would refute the hypothesis.
If a statement, hypothesis, or notion is falsifiable, the potential of proving it wrong exists. It is non-falsifiable if there is no means to prove it wrong.
