The option that is not one of the steps of the water cycle includes options C(Respiration of water into the atmosphere)

and D(Transpiration of water into the atmosphere).

Water cycle can be defined as the constant flow or movement of water through earth, atmosphere and the oceans either in liquid states or vapour.

The four main steps of water cycle includes:

In nature, water circulates mainly within the abiotic (non-living) environment; only a small proportion recycled through living organisms.

Therefore respiration and transpiration which occurs through living organisms doesn't form the major steps of water cycle, hence the correct option is C (Respiration of water into the atmosphere) and D (Transpiration of water into the atmosphere).

In the electrophoresis of plasmid pGLO DNA, one dye may move faster than the other due to differences in the following factors: Molecular size, Charge, Gel concentration and voltage.

1. Molecular size: Smaller molecules or fragments of DNA move faster through the gel matrix compared to larger ones. This is because they can navigate through the pores in the gel more easily.

2. Charge: DNA molecules have a negative charge due to their phosphate groups. The electrophoresis process uses an electric field to separate the molecules based on their charge. Molecules with a stronger negative charge will migrate faster towards the positive electrode.

3. Gel concentration: The concentration of the gel affects the pore size and, subsequently, the migration rate of the DNA molecules. Lower gel concentration results in larger pores, allowing DNA molecules to move faster.

4. Voltage: The electric field strength can also influence the rate of migration. Higher voltage can make the DNA molecules move faster through the gel.

In summary, the dye that moved faster in the electrophoresis of plasmid pGLO DNA likely had a smaller molecular size, stronger negative charge, or experienced a more favorable gel concentration or voltage during the experiment.

Urban Sprawl leads to reduced habitat and fragmentation. Option D

Natural ecosystems are frequently destroyed and fragmented as a result of urban sprawl. Forests, marshes, and other habitats are destroyed when cities grow to make room for new structures, parking lots, and other infrastructure.

The remaining natural areas become fragmented as a result of habitat loss, isolating populations of plants and animals and interfering with their ecological connectedness. Fragmented ecosystems make it harder for species to migrate, reproduce, and obtain suitable resources, which causes biodiversity to dwindle.

Explanation:

A. Power plant     :)

mitochondria provides the energy.

Answer:

1.Small cell: has larger surface-area to volume ratio  

  Bigger Cell:  has little space to volume ratio

2. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.

Amoeba and some bacteria's are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.

Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.

3. Diffusion and Cell Size

The larger a cell is, the greater the surface area available for diffusion. ... Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.

Having many cells help large organisms maintain homeostasis because larger organisms have smaller surface-area to volume ratio ( i.e. does not require large cell to carryout every function in the organism ).

Certain single celled organisms like Amoeba which are flat in nature possess a high surface area to volume ratio therefore diffusion of materials into them are faster and this makes it difficult for them to achieve homeostasis.

Larger cells will definitely posses a larger surface-area to volume ratio and hardly achieve homeostasis.

Hence we can conclude that large organisms maintain homeostasis by been having lower surface area to volume ratio.

An adaptation of desert animals that helps them retain and acquire water in such a hot and dry environment is to evolve an internal air conditioning system to help them stay cool. Thus, the correct option is C.

Adaptation may be defined as the methodology that involves numerous changes through which an organism or species becomes better compatible with its surrounding environment.

Adaptation also characterizes the specific property of organisms through which they acquired certain changes slightly over time to be able to continue to exist in a particular environment.

Statement three "evolved an internal air conditioning system to help them stay cool" represents the process of evolution rather than adaptation.

While excretion of uric acid in place of urine, obtaining water from the plants and animals, and burrowing in moist soil or living in underground dens demonstrate the process of adaptation.

Therefore the correct option for this question is C.

Students perform tests of macromolecules in a laboratory to test whether lipids, carbohydrates, and proteins are present in various foods.

A macromolecule is defined as a very large molecule that is important to various processes like protein or nucleic acid. It is made up of covalently bonded atoms. Many macromolecules are polymers of smaller molecules which are called monomers. Carbohydrates, lipids, proteins, and nucleic acids are the four main types of a macromolecule which are necessary for normal function as well as the survival of our body. We can use indicators to test the presence of macromolecules such as lipids, carbohydrates, and proteins in many foods in laboratory. We will be testing for the presence of carbohydrates such as glucose, and sucrose as well as complex carbohydrates such as starch and proteins.

In the chi-square test of association, as the difference between the observed and expected proportions increases, the chi-square test statistic also increases.

This is because if the claim made in the null hypothesis is true: the claim that frequency of the observed is equal to that of the expected (Oi = Ei) then, the observed and the expected values are close to each other and the difference Oi − Ei  is small for each category and the chi-square test statistic is small.

But when the observed data does not fit to what is expected  as of the null hypothesis, the difference between the observed and  expected values, Oi − Ei  is large producing a large chi square statistic.

Explanation:

Lock and Key states that there is no change needed and that only a certain type will fit. However induced fit says the active site will change to help to substrate fit.

Explanation: According to the lock and key paradigm, an enzyme’s active site exactly matches a certain substrate. According to the induced fit model, when an enzyme binds a substrate, its active site undergoes a conformational change to enhance the fit.

Two ideas that describe an enzyme’s manner of action are induced fit and lock and key. The induced fit hypothesis describes the binding of an enzyme and a non-complementary substrate, whereas lock and key describes the binding of a complementary enzyme and substrate.

Adaptive radiation groups plants and animals into a wide variety of species.

Adaptive radiation, also known as divergent evolution, is a process in which a single ancestral species gives rise to multiple new species that are adapted to a wide variety of ecological niches.

This process often occurs in situations where a new ecological opportunity arises, such as when new habitats become available or when environmental conditions change.

The new species that arise from adaptive radiation often exhibit significant morphological and behavioral differences, as they evolve to exploit different resources and ecological niches. This process can lead to the evolution of a wide variety of forms and functions, including differences in feeding habits, locomotion, and reproduction.

Adaptive radiation is an important driver of biological diversity and is a key process in the evolution of many animal and plant groups.

Explanation:

Prairie dogs' warning barks are a complex example of altruistic behavior, where an individual risks their own safety to warn others of danger. The evolutionary explanation for this behavior is that it benefits the survival and reproduction of the individual's kin, who share a large percentage of their genetic material. Therefore, the correct answer to the question is b.

By warning related prairie dogs, the barking individual is increasing the chances of their kin's survival and therefore the transmission of their shared genes. This is the reason why prairie dogs are more likely to make a warning bark when predators are near related colony members than unrelated ones. While the warning barking prairie dog puts itself at risk, the benefits to its kin outweigh the costs, as more individuals are likely to survive and reproduce. Therefore, the correct answer to the question is b. The warning bark changes the behavior of related prairie dogs nearby, allowing the prairie dog's family to have a better chance of survival and reproduction.
