The ATP-powered proton pump cannot function without sucrose, hence there is no proton gradient. The cotransport protein cannot carry protons without sucrose. Protons don't diffuse down their electrochemical gradient.Therefore, option (A), (C) and (E) are correct.

The coupled transport of chemical substances across a cell membrane where the energy required to move a substance (such as glucose) against a gradient in concentration or in electrical potential is provided by the movement of another substance (such as sodium ion) along its gradient in concentration or in electric potential.

Cotransporters are a subclass of membrane transport proteins that connect the movement of one molecule with its concentration gradient and the movement of another molecule against its concentration gradient. They comprise antiporters and symporters that permit linked or cotransport.

Therefore, in the absence of sucrose,  protons don't move back into the cell through the sucrose-proton cotransport protein.

Zygospores

Zygomycota produce zygospores, which germinate into new hyphae.

Explanation;

The reproductive world of fungi ranges from bursting spores to fruiting bodies.

During asexual reproduction, some hyphae become spore-producing bodies called sporangia or conidia. The group of fungi known as Zygomycota develop sporangia within a sac. This sac then bursts to release the spores.

Once the spores land on a suitable habitat, they germinate a new hypha that grows into a mycelium.

Zygomycota, Ascomycota and Basidiomycota each reproduce sexually. The difference is the structure the spores form in. Basidiomycota form fruiting bodies called mushrooms or basidius; Ascomycota have sacs called ascus; and Zygomycota produce zygospore.

Explanation:

Acid rain harms numerous animals and plants. Thus, the food web suffers. Acid rain kills lake phytoplankton. As a result, phytoplankton-dependent insects die. Therefore, option (C) is correct.

Acid rain, also known as acid deposition, is an all-encompassing word that refers to any form of precipitation that contains acidic components, such as sulfuric or nitric acid, and that falls to the ground from the atmosphere in either a wet or dry form. Acid precipitation can take several forms, such as rain, snow, fog, hail, or even dust.

Rain that contains acid can provide significant challenges for a wide variety of flora and fauna. As a direct consequence of this, the entire food web is disrupted. For instance, phytoplankton in lakes might perish as a direct result of acid rain. As a result of there being less phytoplankton available, the insects, which get their nutrition from it, are starting to starve to death.

Therefore, option (C) is correct.

People who are diagnosed with obsessive-compulsive disorder show increased metabolic activity in the orbitofrontal cortex of the brain.

Obsessive-compulsive disorder (OCD) is a mental health disorder that affects individuals of all ages.

Individuals with OCD exhibit compulsive or repetitive actions that are often irrational and unreasonable. It affects people from all walks of life, including children and adults.

The OCD symptoms include intrusive, unwanted thoughts, images, or impulses (obsessions) and behaviors or actions to relieve the anxiety (compulsions).

Symptoms of OCD: Obsessions that cause unwanted, repetitive, and persistent thoughts or impulses, like fear of germs, or specific numbers or sequences, are common symptoms of OCD.

Repetitive and ritualistic behaviors or compulsions like frequent hand washing or arranging items in a particular order are also a common symptom of OCD.

Diagnosis of OCD: OCD is diagnosed based on the signs and symptoms, as there are no specific laboratory tests to diagnose the condition. Doctors use a combination of psychological evaluations, physical examinations, and medical tests to diagnose OCD.

In addition, doctors may use functional brain imaging tests such as PET or SPECT scans to identify the parts of the brain that have increased metabolic activity.

The orbitofrontal cortex is responsible for decision-making, motivation, and impulse control. People with OCD show increased metabolic activity in this region of the brain.

This increased activity in the orbitofrontal cortex causes obsessive thoughts, leading to compulsive behavior, which relieves the anxiety associated with the obsessions.

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: \(\rm 3x + 4y = 27 -----(equation 1)\)  

For Susy: \(\rm 3x + 2y = 21 -----(equation 2)\)

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

\(\rm 3x + 4y = 27\)

\(\rm - (6x + 4y = 42)\)

Solving above equations, we get:

\(\rm -3x = -15\)

\(\rm x = 5\)

Substituting x = 5 into one of the equations, we can solve for y:

\(\rm 3(5) + 4y = 27\)

\(\rm 15 + 4y = 27\)

\(\rm 4y = 12\)

\(\rm y = 3\)

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

Alleles of a trait that remain together in an individual do not mix, but rather maintain their identity, according to the law of segregation. Self-pollination of heterozygous tall plants (Tt) produces tall and dwarf plants in a 3:1 ratio. The segregationist law is demonstrated. Hence (b) is the correct option.

When self-pollinated, a plant that is heterozygous for tallness will yield both tall and dwarf plants. That is proof. When two heterozygous tall plants are crossed, 25% of the offspring are homozygous tall, 50% are heterozygous tall, and 25% are dwarf plants.When a Tt heterozygous, tall plant crosses with a tt homozygous, short plant, the progeny will be 50% taller because the tall, Tt heterozygous plant produces the gametes T and t with equal odds while the small, tt homozygous plant does not.

The event that occurs during prophase I of meiosis, resulting in an exchange of genetic material between homologous chromosomes, is called crossing over or genetic recombination.

During prophase I of meiosis, the homologous chromosomes pair up and form a tetrad. Within this tetrad, nonsister chromatids from the homologous chromosomes come into close proximity. At certain points along these nonsister chromatids, the genetic material can be exchanged through a process called crossing over or genetic recombination.

This exchange of genetic material between homologous chromosomes leads to the creation of new combinations of alleles and increases genetic variation. Crossing over is an important mechanism in meiosis that contributes to the diversity of offspring and ensures the shuffling and mixing of genetic information from the parents.

Consumption of oxygen (\(O_{2}\)) is used to estimate metabolic rate. Therefore the correct option is option A.

Aerobic respiration, the mechanism by which the body makes ATP (adenosine triphosphate), the energy currency utilised by cells, requires oxygen.

When oxygen is used, it is utilised to metabolise foods and create ATP, resulting in the waste product carbon dioxide (\(CO_{2}\)). The metabolic rate can be calculated by measuring the amount of oxygen used and the amount of carbon dioxide produced.

This is frequently accomplished by the use of indirect calorimetry, which measures the amount of oxygen consumed and carbon dioxide produced over a certain time period to estimate energy expenditure and metabolic rate. Therefore the correct option is option A.

Decreased sympathetic nervous system activity is the result of inhibition of the paraventricular nucleus (pvn) by the transmitter neuropeptide y.

The central nervous system contains a lot of neuropeptide Y  which is present in the hypothalamus. The paraventricular nucleus of the hypothalamus controls autonomic function, feeding behavior and the stress response.

It has been demonstrated that NPY inhibits PVN activity which lowers sympathetic nervous system activity, lowers the stress response and increases food intake. Given that the PVN is involved in the regulation of numerous physiological processes, neuropeptide Y's inhibition of the PVN may also have additional effects on the body.

These side effects could affect body temperature also heart rate, blood pressure and the release of hormones like cortisol, growth hormone and thyroid stimulating hormone.

The paraventricular nucleus (PVN) is an essential component of the hypothalamus that regulates the stress response, appetite, and other autonomic processes.

Neuropeptide Y is a potent modulator of the PVN, and its inhibition results in reduced food intake, increased anxiety-like behavior, and decreased stress responses. Therefore, the result of inhibition of the paraventricular nucleus (PVN) by the transmitter neuropeptide Y is decreased food intake, increased anxiety-like behavior, and decreased stress responses.Explanation:PVN is a part of the hypothalamus that plays an important role in regulating autonomic functions like stress responses, appetite, body temperature, and blood pressure. PVN receives input from various brain areas and is known to produce a number of neuropeptides and hormones, which are involved in the regulation of these functions.

Neuropeptide Y (NPY) is a potent modulator of the PVN, which can bind to its receptors and inhibit or activate its neurons. The exact mechanism of NPY action on PVN is not fully understood, but it is known to have an important role in the regulation of food intake, energy homeostasis, and stress responses.Inhibition of PVN by NPY is mediated by activation of Y1 receptors, which are found on the PVN neurons. NPY binding to Y1 receptors results in decreased intracellular calcium levels, which reduces the firing rate of the PVN neurons.

Plate tectonics may affect organic evolution because the movement of plates may cause a change in b. the environment

Plate tectonics can have a profound impact on organic evolution by bringing about changes in the physical environment. The movement of tectonic plates can lead to the creation of new landforms such as mountains, volcanoes, and ocean basins, as well as the shifting of continents. These geological processes directly influence the climate, distribution of habitats, and availability of resources.

As plates move and collide, they can form barriers or connections between different landmasses and bodies of water. These changes can impact the dispersal and migration of organisms, leading to changes in gene flow and the establishment of new populations. Additionally, the formation of mountains and valleys can create diverse habitats, promoting speciation and providing opportunities for adaptive radiation.

Furthermore, plate tectonics play a role in the redistribution of nutrients, the formation of ocean currents, and the alteration of climatic patterns. These factors influence the availability of food sources, temperature regimes, and ecological interactions, all of which can shape the selective pressures acting on organisms and drive natural selection.

In summary, the movement of tectonic plates can cause significant changes in the physical environment, thereby affecting the distribution, adaptation, and evolution of organisms over time. Therefore, Option b is correct.

Bioaccumulation is the total accumulation of certain chemicals/contaminants in an organism, coming from diverse sources such as water, air, and diet. Therefore the case of mercury occurs when mercury is accumulated in an organism, for example, fish. The most common pathway for this to happen is through the food chain, nonetheless can occur through abiotic means, an example is in fish, where methylmercury is acquired through the gills.

When methylmercury is absorbed through the gastrointestinal tract & enters the bloodstream and goes rapidly to other parts of the body.

Mercury is a persistent substance, which can bioaccumulate, in living organisms, inflicting increasing levels of harm on higher-order species such as predatory fish and fish-eating birds and mammals through a process known as "biomagnification"

The release of processed mercury can lead to a progressive increase in the amount of atmospheric mercury, which enters the atmospheric-soil-water distribution cycles where it can remain in circulation for years. Mercury poisoning is the result of exposure to mercury or mercury compounds resulting in various toxic effects depending on its chemical form and route of exposure.

The major route of human exposure to methylmercury (MeHg) is largely through eating contaminated fish, seafood, and wildlife that have been exposed to mercury through the ingestion of contaminated lower organisms.

King mackerel, marlin, orange roughy, shark, swordfish, tilefish, ahi tuna, and all contain high levels of mercury.

Human activity is the main cause of mercury release, especially coal-fired power stations, residential coal burning for heating and cooking, industrial processes, waste incinerators, and as a result of mining for mercury, gold, and other metals.
