Answer:
a. rigor mortis.
Explanation:
Electricity refers to the power generated from various power sources or power plants such as hydroelectric, wind turbine, solar, nuclear, etc.
Generally, the power supplied to homes, offices and buildings cycles at a frequency of 60 Hertz or 50 Hertz depending on the parameters chosen in countries. If a power line is dropped accidentally into a holding tank for frogs, it would immediately cause their muscles to become stiff due to the current flowing through the power line i.e because the power line is energized and has electrons moving across its terminals. This stiffness is because the high frequency stimuli is causing rigor mortis.
From his observations in the oceanic islands like the Galapagos, Darwin felt that: isolation is a significant factor in adaptation and speciation spontaneous generation is a significant factor in adaptation and speciation volcanic soils are a significatnt factor in adaptation and speciation inheritance of acquired characteristics is a significant factor in adaptation and speciation. none of these is correct
Answer:
isolation is a significant factor in adaptation and speciation
Explanation:
In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).

The statement which is true about HOX genes is they regulate the development of body parts.
What do you mean by HOX genes?HOX genes may be defined as components of the homeotic transcription factor family that play a key part in controlling the body plan.
HOX genes play two important roles, which are given below:
Specifying the place where the limb of organisms forms.Specifying whether the particular mesenchyme cells will become stylopod, zeugopod, and autopod.Therefore, the statement which is true about HOX genes is they regulate the development of body parts.

The amount of light, pressure, and temperature are examples of?
Explanation:
The answer is No. You know light from Stars travel in cold temperature of space and different pressure as they enter our planet after travelling many light year to reach us at the same the speed.
Light bends when entering a different medium(refraction). Even if the medium is same and the temperature is different it will get bend. As the 2 different temperature air behave like 2 mediums (Due to distribution of atoms ).
But light doesn't’ bend by heating or by putting pressure on it.

Explanation:
The mutation rate is the probability of a single gene mutating in an offspring bug.
a. True
b. False
Answer:
True
Explanation:
A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.
Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway. You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal. You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present. When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
Answer the following question in the space give.
A. From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

4. A bacterium is discovered with new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but produces hydrogen gas instead of NADH. a. Write a balanced equation for the new reaction. b. What affect does this mutation have on the amount of ATP produced from one glucose molecule
A bacterium is discovered with a new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but makes H₂; the reactant is isocitrate, and the product is alpha-ketoglutarate. As the proton count decreases, less ATP is produced.
What is the importance of the proton gradient in energy production?The proton gradient is formed during the electron transfer chain (ETC) by using all the NADH and FADH₂ that are derived from the glycolysis and kreb cycle. NADH and FADH₂, for example, are two compounds that travel through the different complexes to create the proton gradient, which later produces ATP; however, when H₂ is produced instead of NADH, less of a proton gradient is formed, and thus less ATP is produced. The equation is isocitrate+ NAD+ → alpha-ketoglutarate +CO₂ + H+
Hence, the reaction is composed of substrates isocitrate, NAD+, and products alpha-ketoglutarate, CO₂, and a proton (H+), which will be formed with significantly less ATP than the normal ATP produced from the one glucose.

Which of these describes a nebula
Answer:
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."

Respiratory syncytial virus uses the nasopharynx as its main replication site. has symptoms of dyspnea and rales. causes serious disease in infants 6 months old or younger. can be treated with the antiviral aerosol ribavirin. All of the choices are correct.
Answer:
All of the choices are correct
Explanation:
The respiratory syncytial virus (RSV) is an enveloped, negative-strand RNA virus (Paramyxoviridae family) capable of infecting ciliated cells of the airways by using its surface glycoproteins G and F for attachment and fusion during viral entry in target cells. RSV can affect the lungs and parts of the respiratory system (e.g., nasopharynx). Although RSV generally causes mild, cold-like symptoms, this virus may also lead to severe infection in babies (12 months) and infants, being one of the most common types of respiratory infections in children, older adults, and immunocompromised patients. Some common symptoms in individuals with RSV pneumonia include fever, nonproductive cough, dyspnea, wheezes, rales, rhonchi, etc.
