Which of the following is maintained across the terminals of a battery?
a) a potential difference
b) a voltage drop
c) an electric charge
d) both A and B
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.

How often does the body perform cellular respiration? once in the morning and once at night only at night continuously only when the body runs out of ATP
continuously
its breaking down the chemical bounds in ATP and its energy is essential for survival
Answer: Constantly
Explanation:
Cellular respiration is a kind of metabolic process by which the carbohydrates of the body are broken down into ATP molecules in the presence of oxygen.
The energy is stored in the bonds of ATP molecules which is released when the bonds are broken.
The cells of the body needs energy continuously so the cellular respiration occurs constantly.
In a laboratory population of flies, the female flies are gray and the males are yellowish gray. Biologists observed that all the male flies had an equal chance for reproduction, but the male flies with the brightest colors were more likely to successfully reproduce. What phenomenon could explain such a change?
Answer:
The correct answer is sexual selection.
Explanation:
Sexual selection is illustrated as a medium of natural selection that comprises a selection of mates of the contrary sex by the individual of one biological sex, and at the same time competing with the individuals of the similar sex for the members of the contrary sex.
As in the given question, the male flies exhibiting brightest colors are more effective in reproducing in comparison to the male flies exhibiting light colors, it shows that the phenomenon of sexual selection is taking place.
What two factors affected the development of new species
The development of new species is influenced by environmental conditions and geographic separation, leading to genetic isolation and speciation through adaptation to new ecological pressures and different environments.
The development of new species is primarily influenced by two factors: environmental conditions and geographic separation.
Environmental changes, such as a significant drop in water level, can cause a population to split into two groups, leading to a small subsection of the population being exposed to new ecological pressures. This smaller group's gene pool can quickly evolve if a favorable trait emerges, contributing to the rise of new species.
Additionally, geographic separation can lead to speciation by isolating portions of a population in different environments, prompting them to adapt in diverse ways. For example, mammals living in mountainous regions may evolve increased fur for the cold, while those in lowlands develop differently. Over time, these adaptations may lead to the formation of new species as these groups experience genetic isolation.

describe how lichen are used to indicate air quality
Lichens are composite organisms in which a single species of fungus (mycobiont) lives symbiotically with one or more algal species (phycobionts), some of which may be nitrogen (N) fixing (cyanolichens), e.g. members of the blue green algae. The fungus provides structure and protection for the algae which reciprocates, providing energy and assimilates, via photosynthesis. Many secondary metabolites are synthesised by the fungus, which are unique to lichen symbioses.
In Europe lichens have been used as sensitive bioindicators of air quality for more than a century. As with most vegetation, lichens show a range of sensitivities to pollutants. Not all lichens are sensitive to a particular pollutant, some can be remarkably tolerant. Among lichens are species that are sensitive to sulphur, nitrogen, acidity, halogens (e.g. fluoride), heavy metals and ozone.

How is mitosis different from meiosis
I believe Mitosis is your individual cells dividing and meiosis is you and the males cells dividing but I might be wrong I'm not good at this subject sorry
Answer:
Mitosis produces 2 daughter cells with the same number of chromosomes as the parent cell while Meiosis results in 4 daughter cells with half of their parent's chromosomes.
Explanation:
Cells divide and reproduce in two different ways that are mitosis and meiosis. The fundamental difference in both cell division is that mitosis results in 2 identical daughter cells, but meiosis results in 4 sex cells with half chromosome numbers.
In mitosis, daughter cells are genetically identical , creates all body cells apart from sex cells and no recombination occurs, whereas daughter cells are different, creates only sex cells, and recombination occurs in meiosis.
What is the genetic contribution to the onset of autism?
Answer:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by very early onset of dysfunction in social communication and interaction, repetitive behavior, and limited interest. It is now believed that ASD is a result of complex gene-environment interactions, with strong and clear genetic influences. Hope this helps!
The onset of autism is significantly influenced by genetics, with high concordance rates observed in identical twins. Various gene mutations and environmental factors also contribute to the development of ASD.
The onset of autism spectrum disorder (ASD) is significantly influenced by genetics.
Research has shown high concordance rates for autism in monozygotic (identical) twins, ranging between 60%-90%, compared to much lower rates of 5%-10% in dizygotic (fraternal) twins and siblings. This suggests a strong genetic component. Studies have identified various genes and gene mutations involved in autism, particularly those crucial for the formation of synaptic circuits that facilitate communication between different brain regions. For example, de novo mutations, which are spontaneous and not inherited from either parent, have been frequently linked to cases of autism.Which of those methods of waste management is most likely to produce air pollution

Complete the sentence about the continental drift theory
Alfred wegener proposed the theory of continental drift after he saw that the coasts of ___ and ___ looked like two interlocking puzzle pieces
1. A. Eastern Africa
B. Northern Africa
C. Western Africa
2. A. Eastern North America
B. Eastern South America
C. Western South America
The correct answers are:
1. C. Western Africa;
2. B. Eastern South America;
Alfred Wegener has spent lot of times looking at maps, as it was his job. One day he noticed something peculiar, the western coast of Africa and the eastern coast of South America were an almost perfect match. They looked like peaces of puzzle that belong together. In his mind this was suggesting that these two continents had been merged in the past, and than broke apart. He later got proof about his theory by observing the sea mounts in the Atlantic Ocean.
Answer:
c. Western Africa
B. Eastern South America
Explanation:
Why are certain traits adaptations in one ecosystem, but not in another? A. All ecosystems have the same amount of competition. B. Organisms can learn new adaptations. C. Ecosystems can have different conditions. D. Organisms lose adaptations when they migrate.
i am going to choose c because i think it is correct
Answer: C. Ecosystems can have different conditions.
Explanation:
Adaptations are the changes that occur in the physiology, genome, morphology and the behavior of the organisms so as to support their survival in the adverse environmental conditions. An ecosystem is a biotic community where the living beings interact with their non-living environment. The abiotic (non-living) and biotic (living) factors may vary from ecosystem to ecosystem depending upon the location.
Certain traits adaptations can be seen in one ecosystem but not in another this occurs due to the fact that C. Ecosystems can have different conditions. Organisms adapt according to their environment. For example, a white coat over the hare species will help the population to remain insulated and protected against the predators in snow region but the same species when exposed to tropical forests will not be able to survive due to excess warm temperature and will be detected by the predators easily.

which information do tiny fossils found in drilling samples from earths crust reveal about earths history?
Answer: microfossils help us decode the climate and what the ecosystem was like in the past.
Explanation:
Fossils are any remainder or evidence of an organism that lived long ago. The preserved remains of living beings or their traces of the past are documents of the history of life on planet Earth.
Depending on their size, they are classified as microfosiles or macrosophiles.
Macrophiles are visible sized fossils, such as bones, shells or petrified wood. While the microfossils are seen with the microscope. They are important for correlating sedimentary layers, when looking for oil, and they help us decipher the climate and what the ecosystem was like in the past. Examples of microfossils are diatomaceous, radiolaria and foraminifera.

Examine the air pressure map.
Which type of line is shown on the map?
isobar
isotherm
radar
humidity
The correct answer is - isobar.
The isobars are closed lines that are connecting spots with the same air pressure, thus giving us information about the air pressure in certain places. The air pressure can be standard, low, or high. The standard air pressure is 1013.25 mbar, the low air pressure is bellow the value of the standard one, and the high air pressure is above the standard one.
The low air pressure means that there are warm air masses in the area, or more water vapor in the atmosphere, while the high air pressure means that there are cold air masses present in the area. The reason why the warm air masses have low air pressure is that they are less dense, thus have less mass, and make less pressure, while the cold air masses are denser, have more mass, and make more pressure.
The unit most commonly used for measuring the air pressure is milibar (mbar)

What is gradualism? When is it most likely to apply?
Gradualism refers to the theory that evolution occurs through slow and steady changes, while punctuated equilibrium involves long periods of stability interrupted by rapid changes. Gradualism is expected in stable environments, whereas punctuated equilibrium may follow events like mass extinctions.
Gradualism in Evolutionary Biology
Gradualism is the theory that evolution occurs through a process of slow, steady, and gradual change. This concept implies that new species arise from the accumulation of small, incremental modifications over vast periods of time. Gradualism is most likely to apply in situations where environmental conditions are relatively stable and selection pressures change slowly, allowing for these small changes to accumulate into significant differences over time.
On the other hand, the punctuated equilibrium model of evolution describes periods of relative stasis in species, interrupted by bursts of rapid change. These bursts often occur due to significant environmental changes or isolation events that trigger speciation. In the context of the extinction of the dinosaurs, it's predicted that the punctuated equilibrium model would follow, as such a massive extinction event likely caused rapid environmental changes that could have led to the rapid evolution of new species.
While the concepts of gradualism and punctuated equilibrium may seem opposed, they are not necessarily mutually exclusive. The differences often come down to the time scale and granularity with which evolutionary change is studied. Disagreements about speciation models do not threaten the overarching theory of evolution by natural selection, which is supported by extensive scientific research.

Jazelyn needs to create a project that shows reproductive isolation in action and decides
Here is the complete question:
Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
A. A video that shows a large river that has penguin populations on both sides.
B. A video that shows penguin species that have different mating dances.
C. A video that shows a penguin that is laying eggs.
D. A video that shows penguins in a tidal pool and an open ocean.
ANSWER
The correct option is B.
Reproductive isolation refers to evolution mechanisms that make it impossible for member of different species from successfully mating or producing fertile offspring. There are two different types of barriers that can prevent different species from mating, these are prezygotic and postzygotic barriers.
Prezygotic barriers are those hindrances that prevent different species from producing offspring by preventing formation of zygote. An example of this barrier is difference in courtship behaviors. Post zygotic barriers prevent offspring produced by different species from being fertile, that is, they are sterile.
Answer:
b
