Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Answer:

The following Statements accurately portrays role of natural selection in antibiotic resistance

c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.

d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce

e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce

Explanation:

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.

As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection

In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving  bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers

The day-to-day change in the temperature of air on the Earth is controlled by the energies which are received and lost from the surface of the planet.

During summers, the sunrays hit Earth at a very steep angle. The sunlight does not spread out as much, thus increasing the amount of energy which is hitting any spot. Also, the long daylight hours allows Earth time to reach the warm temperatures.

The daily air temperatures at Earth's surface are in control of the incoming and outgoing energies. During the day, the temperature of air increases as energy gain exceeds the energy lost from the surface of Earth. And throughout the night, the air temperature decreases as the surface of Earth loses more energy than it receives.

2.Eggs cooking is a chemical change

3.Salt dissolving is a physical change

4.Wood burning is a chemical change

5. Fireworks exploding is a chemical change

A substance can change physically even when no new substance is created as a result of the change. It simply modifies the substance's outward attributes, such as its shape, size, texture, or phase (such as solid, liquid, or gas).

When a compound undergoes a chemical change, a new substance or substances with new chemical properties are created. Chemical bonds are broken and formed as a result of this process, which transforms one or more chemicals into one or more new substances. Chemical changes can release or absorb energy (heat, light, or sound), and they are frequently irreversible.

Answer: The arrangements and correct order of the above described genetic and behavioural adaptations includes:

A.) Camouflage: This is a survival adaptation by which an animal blends in and is hidden in its surroundings.

B.) Mimicry: This is an organism exhibiting characteristics similar to one known to be dangerous.

C.) Tropism: This is the growth or movement of an organism ( usually plant) in response to a stimulus.

D.) Venom: This is a poison secreted by animals for either defensive or offensive purposes.

E.) Mutualism: This is the interaction of two organisms where both benefits.

F.) Commensalism: This is the interaction of two organisms where one is helped and the other is neither helped nor harmed.

Explanation:

In the study of organisms and it's environment, they are able to adapt through genetic and behavioural mechanisms. Adaptation of defined as the ability of organisms to become fitted to its environment by modifying or changing its features. These features may be structural or behavioural.

STRUCTURAL ADAPTATION: Almost every part of the body of a living organism is structurally adapted to its mode of life. They are structurally adapted for the following specific functions:

--> Escape and defence: many animals use CAMOUFLAGE to remain unnoticed by potential predators. While some others are capable of producing poisonous VENOMS which may become offensive to the predators. Also many harmless organisms may possess structural behaviours that may MIMIC dangerous organisms thereby keeping their predators at arms length.

--> obtaining food: organisms needs to possess some structural features that will enable them obtain food in their environment. This usually leads to forming various feeding relationship ( which may be MUTUALISTIC or COMMENSALISM) with one another to be able to obtain food for survival.

BEHAVIOURAL ADAPTATION: Behaviour is everything an organism does in response to changes in its environment. Plants do exhibit behavioural adaptations and a typical example is the phototrophic movement of plant shoots which is a type of TROPISM.

One major difference wold be the final stage of each star's life.

An average size star will eventually use up all of the hydrogen fuel in its core and expand into a red giant, before shedding its outer layers and becoming a white dwarf. The white dwarf will continue to slowly cool over billions of years.

A high mass star will follow a more explosive and catastrophic path. After it has used up all of its hydrogen fuel it will continue to fuse heavier elements around its core. Eventually the core will collapse in on itself, triggering a supernova explosion that blasts the outer layers of the star into space. The remaining core will either form a neuron star or a black hole, depending on its mass.

Answer:

repeated DNA sequences decrease the target specificity of the CRISPR-Cas system, and may lead to off-target effects  

Explanation:

The CRISPR-Cas system is a versatile and powerful tool for gene editing. This gene-editing tool consists of a single guide RNA (sgRNA) that guides the Cas endonuclease protein to the appropriate genomic locus, where Cas generate a double-strand break in the DNA and thus induces DNA repair either by Non-homologous end joining (NHEJ) or Homologous Recombination (HR) repair pathways. The sgRNA consists of a 17-20 nucleotide sequence which is complementary to the target DNA, this sequence is called crispr RNA (crRNA). The existence of repeated DNA sequences hampers the specificity of the CRISPR-Cas tool because a particular sgRNA is able to guide Cas9 to different genomic loci that have the same (repeated) nucleotide sequence complementary to the crRNA. In consequence, repeated DNA sequences may lead to undesired off-target effects, i.e., unintended cleavage (and therefore unintended mutations) at untargeted genomic sites.

Explanation:

The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .

Answer:

As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.

Explanation:

Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.

To put it simply, the intrinsic hand muscles are divided anatomically into the Thenar group, which is located at the base of the thumb, the Hypothenar Group, which is situated at the base of the small finger, and everyone in between .

The intrinsic hand is made up of four muscular groups. These are the lumbrical, interossei, thenar, and hypothenar muscles. The intrinsic muscles, including the lumbricals & interosseus muscles, balance finger movement during normal hand function and produce this broad sweeping motion. They are also in charge of connecting the extension of the interphalangeal joints (IP) with the flexion of the metacarpophalangeal joint (MCP). The carpal & metacarpal bones serve as the origin & insertion points for the intrinsic hand muscles. The forearm is frequently the origin of the extrinsic hand muscles, which enter into hand . The majority of the hand's intrinsic muscles, including all seven interossei, three hypothenar muscle fibres, the adductor hanced, the deep heads of the FPB, and the two flexors longus, are innervated by the ulnar nerve.
