Which of the following is an example of chemical energy in nature?
A.
the energy that builds up when friction prevents rocks from moving along a fault

B.
the energy contained in the bonds of a sugar molecule

C.
the stored energy of a boulder at the top of a cliff

D.
the energy of flowing water in a mountain stream

Answer:

The correct answer will be- carbohydrates

Explanation:

The carbohydrates are one of the four abundant biomolecules which are composed of the polymers of the sugar molecules.

The carbohydrates play important roles in the organism from a structural entity to storage functions. The carbohydrates formed of one type of sugar are known as monosaccharide, of two sugars are known as disaccharide  and the more than two types are known as polysaccharides.

Thus, carbohydrate is the correct answer.

D.  Absorption

This is because when food materials are broken down the nutrients must be absorbed by the body.

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.

Our Solar System, including Earth, is located in one of the spiral arms of the Milky Way galaxy, specifically the Orion Arm. We're not at the galactic center or the central ring, nor outside the spirals. This location helps preserve life on Earth by reducing exposure to hazardous cosmic radiation.

The Solar System, including our Earth and other planets, is situated in one of the spiral arms of the Milky Way galaxy, more specifically in the outer part named the Orion Arm. It is not at the galactic center or the central ring of the Milky Way. We are also not situated outside the spirals of our galaxy.

This spiral arm is filled with gas, dust, and a number of stars. Our position in the galaxy is a key factor in preserving life on Earth because residing in a less dense part of the galaxy reduces our exposure to potentially hazardous cosmic radiation.

A (sorry if wrong) !

Yes your answer is correct I think

ground water forms when water from the surface seeps into the ground

It is formed by the rain. Or if it doesn’t rain then it’s formed by variations of components.

The answer to this is B. Methane

Pesticides have a major effect on biological diversity, alongside habitat loss and climate change. They can have short-term toxic effects on directly exposed organisms, and long-term effects can result from changes to habitats and the food chain. Policy intervention and greater coherence are urgently needed!

Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. Transfer RNA (tRNA) is the key to deciphering the code words in mRNA

Answer: It acts as the intermediate between the genetic information of DNA and amino acid sequence of protein.

Explanation:

The mRNA contains the codons that are complementary to the sequence of the nucleotide on the template strand of the DNA.

Then with the help of the ribosomes and tRNA it directs the formation of amino acids.

It carries the genetic information hence, called as messenger RNA. The molecule of the mRNA is made of single strands of the adenine, cytosine, guanine and uracil kept together by sugar phosphate backbone.

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.

A. Most people thought that trillium was not getting enough sunlight in the forest.

Explanation – Scientists used to believe that the population of trillium decreased because there were not enough sunlight to reach these plants. Later, it was found that deer used to eat the flowers of trillium plant that led to the decrease of its population.

The seed of the trillium plant is very nutritious and hence consumed by the deer. Because of this, trilliums were found to be unlikely to recolonize local areas on their own.  

Answer:

Most people thought that garlic mustard was crowding out trillium in the forest.

I guess its D because when you burn stuff the smoke goes into the air

Burning in an incinerator is the main cause of air pollution, and this method of waste management is hazardous, hence option D is correct.

The method of burning solid wastes in a big furnace at a very elevated temperature whereby making ash is called Incineration.

Incineration is the methodology of igniting hazardous materials at temperatures high enough to eradicate impurities. Incineration is run in an “incinerator,” which is a kind of furnace conceived for steaming hazardous materials in a blast section, it is a kind of container that use  fuel concern to generate heat and burns the waste

It is a waste therapy process that includes the discharge of organic substances managed in waste materials.

Therefore, burning in an incinerator is the correct option.

bounce check and insufficient funds

Explanation:

A is a check that you have written that you cannot pay due to bounced check or insufficient funds.

A bank reconciliation mainly computed by an accountant, gives the difference between the balance in relation to the bank statement and the cash balance with respect to the accounting records of the depositor in a particular financial institution.

In Financial accounting, a bank statement can be defined as an official summary or list of financial transactions, which typically comprises of the amount of money that has been paid into or withdrawn from an account by an individual or business entity over a specific period of time.

Bank customers are advised to frequently reconcile their records with bank statements in order to prevent non-sufficient funds (NSF) checks.

Therefore,  A is a check that you have written that you cannot pay due to bounced check or insufficient funds.

A group of interacting individuals belonging to one species and living in same geographical area

in biology, a population is the number of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding

Im not completely sure but I think the answer is Solar Eclipse.

Sorry if Im not correct btw

The geographic term is elevation

1) Many things can help lessen or prevent air pollution. We can plant more trees to help rid the atmosphere of the harmful gasses our factories release. We can reduce the number of smoke-emitting factories. Use solar power more too.

2) Air pollution affects our health in many ways. Just as smoking a cigarette can pose major health implications, so can breathing the polluted air that is constantly being release by all our cars and other machinery. Our life-spans can be shortened by the pollution, and more diseases could be caused to outbreak by harmful chemicals in the atmosphere.

1. C. Process one describes cloning and process two describe artificial selection

Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.

2. C. Polygenic

A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.

3. C. The BW mice would have black and white patches

Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.

4. D. Polygenic

Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.

Prezygotic and postzygotic isolating mechanisms prevent interbreeding between different species. Prezygotic isolation occurs before fertilization, including mechanisms like habitat isolation and temporal isolation. Postzygotic isolation happens after fertilization, including mechanisms like reduced hybrid viability and reduced hybrid fertility.

Prezygotic and postzygotic isolation mechanisms are both part of what scientists call reproductive isolation, which prevents different species from interbreeding. However, they operate at different stages of the reproductive process.

Prior to fertilisation, zygotic isolation takes place. It includes mechanisms like habitat isolation, temporal isolation, behavioural isolation, mechanical isolation, and gametic isolation. For instance, two species might live in the same area, but breed at different times of year (temporal isolation), or they might have different courtship behaviours that prevent them from successfully mating (behavioural isolation).

Postzygotic isolation, on the other hand, takes place after fertilization. It includes mechanisms like reduced hybrid viability, reduced hybrid fertility, and hybrid breakdown. For instance, even if two different species do mate and produce offspring, those offspring might be weak and unable to survive (reduced hybrid viability), or they might be healthy but sterile, unable to have offspring of their own (reduced hybrid fertility).
