Extant nonbird reptiles are __________, whereas birds are different in that they are __________. View Available Hint(s)for Part A amniotes; not amniotic ectothermic; endothermic scaly; lacking in scales endothermic; ectothermic
Answers
Extant nonbird reptiles are ectothermic, whereas birds are different in that they are endothermic. The correct answer is option B.
Extant nonbird reptiles, such as turtles, lizards, and crocodiles, are ectothermic, which means that their body temperature is determined by the environment.
They cannot regulate their body temperature internally and instead rely on external heat sources to warm up or seek shade to cool down.
Additionally, these reptiles lay amniotic eggs that are protected by a shell, which allows them to survive in diverse environments, such as deserts, forests, and oceans.
In contrast, birds are endothermic, meaning that they can maintain a constant internal body temperature through physiological processes such as shivering or panting.
They can maintain a high metabolism, allowing them to fly and maintain activity levels in various environments. Birds also lay amniotic eggs, but their eggs have hard shells and internal membranes that prevent water loss and allow for gas exchange.
Thus, while both nonbird reptiles and birds share the trait of laying amniotic eggs, they differ in their ability to regulate body temperature and metabolism. therefore, the correct answer is ectothermic and endothermic, option B.

For every molecule of O₂ that is released by photosystem II two H₂O molecules are needed, which together pass four electrons to the PS II reaction-center complex.
Photosystem II (or water-plastoquinone oxidoreductase) is the principal protein complex in the light-reliant responses of oxygenic photosynthesis. It is situated in the thylakoid layer of plants, green growth, and cyanobacteria. Inside the photosystem, chemicals catch photons of light to stimulate electrons that are then moved through various coenzymes and cofactors to diminish plastoquinone to plastoquinol. The stimulated electrons are supplanted by oxidizing water to shape hydrogen particles and sub-atomic oxygen.
The oxygen-advancing complex is the site of water oxidation. It is a metallo-oxo group containing four manganese particles (in oxidation states going from +3 to +4)[6] and one divalent calcium particle. At the point when it oxidizes water, creating oxygen gas and protons, it consecutively conveys the four electrons from water to a tyrosine (D1-Y161) sidechain and afterward to P680 itself.

Compare and contrast negative and positive feedback loops. Which one is more common? Why?
Answers
Answer:
Negative Feedback LoopsA negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.The negative feedback mechanism moves the variable factors towards the stable state or homeostasis after the control unit interprets the extent of the deviation.Negative feedback loops are more common than positive ones as they tend to stabilize the system.The loop detects the change in output and acts in the opposite direction to nullify the stimulus causing the change.These loops are activated under two conditions; when the value of the variable is above the normal value and has to be brought down and when the value of the variable is below the normal values and has to be brought up.Negative feedback mechanisms occur as a part of homeostasis to bring the variables back to their normal levels by counteracting the stimulus, causing the deviation in the first place.Like in a positive feedback mechanism, a negative feedback mechanism also contains different components that together help to maintain a stable state.Examples of Negative Feedback Mechanism
1. Regulation of blood glucose level
2. Temperature regulation
Positive Feedback LoopA positive feedback mechanism, as the name suggests, is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation.A positive feedback mechanism amplifies the deviations and brings state changes to the output.Positive feedback mechanisms are far less common than negative feedback mechanisms as it moves the body away from homeostasis.The process of positive feedback mechanism progressively amplifies the response as long as the stimulus is continued.The positive feedback loop can consist of either a single component that activates its own activity or several components with direct and indirect interactions.Positive feedback loops in biological processes are often observed in processes that need to occur quickly and towards completion as the output tends to increase the effect of the stimulus.Positive mechanisms are very few within living systems like the human body, but these can also be observed in the ecosystem, like in the case of ripening of fruit.Examples of Positive Feedback Mechanism
1. Menstrual cycle
2. Childbirth
Negative feedback loops are more common than positive ones as they tend to stabilize the system.
Positive Feedback vs Negative Feedback (8 Key Differences)Definition
The positive feedback mechanism is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation. A negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.Effect on the homeostasis
A positive feedback mechanism breaks down the homeostasis system of the body. A negative feedback mechanism works to maintain the conditions of homeostasis in the body.Occurrence
The positive feedback mechanism is less common and occurs in specific situations.The negative feedback mechanism is more common and occurs in different organs and systems in the body.Stability
The positive feedback mechanism is less stable.The negative feedback mechanism is more stable.Effect
In a system with a positive feedback mechanism, the effective input is increased by the addition of actual input with the feedback signal.In a system with a negative feedback mechanism, the effective input is decreased as the feedback signal inhibits the actual input.External interruption
A positive feedback mechanism might require an external interruption.A negative feedback mechanism doesn’t require an external interruption.Changes
Positive loops enhances the change in physiological factors.Negative loops resists changes in physiological factors.Examples
Positive feedback mechanism in nature is observed during childbirth in humans and during the ripening of fruits. The negative feedback mechanism is observed during thermoregulation and maintaining the blood glucose level.Earth Science

They can prevent hurricanes and other damaging storms.
O Lower costs for flood insurance.
O They result in lower taxes.
O They have no maintenance costs.
Answers
Answer:
A possible benefit of flood mitigation efforts is lower costs for flood insurance. By reducing the risk of flooding, flood insurance premiums may be reduced or eliminated, saving property owners money. Flood mitigation efforts can also help to reduce the overall cost of flood damage, which can be significant, and may help to prevent the need for costly emergency responses. However, flood mitigation efforts do not prevent hurricanes and other storms, do not necessarily result in lower taxes, and may require ongoing maintenance costs to remain effective.
What positive effect can mutation have on a population?
a) It increased the genetic variation within the population.
b)It eliminates the genetically weak members of a population.
c)It decreases competition for resources between the population's different species.
d)It ensures that a population will not produce more offspring than the habitat can support.
Answers
Answer:
In biology, a mutation is a change in the DNA sequence of an organism. Mutations can have different effects on a population, and not all of them are necessarily negative. Here are some positive effects that mutations can have on a population:
Increased genetic diversity: Mutations introduce new genetic variation into a population, which can increase its adaptability to changing environments. This can be particularly advantageous in situations where a population faces new challenges, such as the emergence of a new predator or a changing climate.
Enhanced survival and reproduction: Some mutations can improve an organism's ability to survive and reproduce. For example, a mutation that confers resistance to a particular disease or toxin can increase an organism's chances of survival in an environment where that disease or toxin is present.
Evolutionary innovation: Mutations can create new traits and functions that did not exist in a population before. This can lead to evolutionary innovation and the emergence of new species. For example, mutations that enable the development of new structures or functions in an organism can lead to the evolution of complex organs or behaviors.
It's important to note that the positive effects of mutations are often dependent on the specific context of a population and environment. Mutations can also have negative effects, such as increasing the likelihood of disease or reducing an organism's fitness. Therefore, the role of mutations in evolution is complex and multifaceted.

Which best describes a neutralization reaction? areaction between an acid and a base Oareaction between two acids O a reaction between a base and a salt Oa reaction between two salts
Answers
The statement best describes a neutralization reaction is a reaction between an acid and a base. The correct option is a.
What is neutralization?Neutralization is the reaction that occurs when acids and bases of equal strength react to generate salt and water. Because acid and bases cancel each other out, the salt generated in the reaction is neutral.
Neutralization is the reaction of an acid and a base that causes the pH to rise to 7. It is a useful process that occurs in everyday life, such as the treatment of acid indigestion and the addition of lime to acidic soil. Neutralization lowers the pH of alkali to around seven.
Taking a base helps to neutralize excess acid in our stomach. Because formic acid is present in the ant sting, it can be painful. Using moist baking soda, which is basic in nature, we can neutralize the acid action and reduce the discomfort caused by the sting.

If 50DD/dd pairs of parrots mate, and each pair has 2 offspring, how many of the 100 offspring would you expect to be Dd? A. 0 B. 100 C. 75 D. 50
Answers
If 50DD/dd pairs of parrots mate and each pair has two offspring, the 100 offspring would you expect to be Dd is B. 100.
As the given problem already specifies the genotype of parents, we can apply the rules of Mendelian Genetics to solve it. If both parents are heterozygous, they carry a dominant allele (D) and a recessive allele (d) each. So, we get: 50 DD/dd pairs of parrots. Each pair has 2 offspring. Total offspring produced= 50 DD x 2 + 50 dd x 2 = 200
Offspring that would be Dd: From the above, 50DD/dd pairs are there, so 50% of pairs are expected to have Dd offspring, so 100 Dd offspring are expected. In conclusion, the expected number of Dd offspring in 100 offspring produced by 50DD/dd pairs of parrots mating is 100. Therefore, the correct option is B. 100.

Individuals who are heterozygous for the sickle-cell allele have one normal allele and one mutated allele. The mutation causes a change in the shape of hemoglobin, the protein responsible for carrying oxygen in the blood.
Under normal conditions, individuals with one normal allele are able to produce enough normal hemoglobin to function properly. However, under certain circumstances, such as low oxygen levels or physical exertion, the mutated hemoglobin can clump together, causing red blood cells to become misshapen and break down. This can lead to a range of health problems, including anemia, pain, and organ damage.

A drug that caused more chlorine to enter into the cell would cause the resting membrane potential to ________________ compared to normal.
Answers
A drug that caused more chlorine to enter into the cell would cause the resting membrane potential to become more negative compared to normal. The resting membrane potential is defined as the electrical charge difference between the inner and outer sides of the cell membrane at rest or when a cell is not conducting an impulse.
Neurons are examples of excitable cells with resting membrane potential. The resting membrane potential of a neuron ranges from -60mV to -80mV, and it can fluctuate between cells. This is owing to the fact that there is no set RMP for all cells; rather, it varies depending on the type of cell. In a resting neuron, there is a greater amount of negative ions on the inside of the cell than on the outside. This difference in charge is established by the cell membrane, which acts as a barrier between the inside and outside of the cell and regulates the flow of ions in and out of the cell. When a drug causes more chloride to enter a cell, it will result in the concentration of negative ions on the inside of the cell to rise. This will cause the RMP of the cell to become more negative than usual. Conversely, if a drug causes more sodium ions to enter the cell, the RMP of the cell will become more positive. The RMP has a significant impact on the excitability of the cell and its ability to conduct electrical impulses. Altering the RMP through drug treatment can cause a wide range of physiological and pathological changes in the body, ranging from mild to severe.
