Answer:

True.

Explanation:

Yes, the number of heavy storms has increased due to global warming because of the holding power of moisture by the atmosphere due to higher temperature. When the air is warmed, the air can hold more water at that temperature so due to more holding power of moisture by the air the number of storms increases. One NASA study supports that global warming is causing the increase in number of extreme storms especially in the tropical ocean.

The role of salicylic acid in plant defense responses is b) activating systemically acquired plant resistance

Growth hormone is an organic compound both naturally occurring and man-made that can promote plant growth and development. Hormones control plant growth and development, by influencing cell division, cell elongation, and cell differentiation.

Salicylic acid is a phenolic compound that plays a role in regulating plant growth. These phenolic compounds can increase plant growth and have an effect on protecting the development of antistress programs. Resistance to disease in the process of plant production can be achieved by using biopesticides through the induction of systemic resistance by increasing secondary metabolites with salicylic acid. Salicylic acid plays an important role in induced systemic resistance in response to pathogenic infections. The mechanism of plant resistance to disease can be in the form of physical or chemical resistance. Salicylic acid is more dominant to overcome the attack of biotrophic pathogens.

Answer:

The passive transport of a substance by its concentration gradient through a protein channel is called facilitated diffusion.

Explanation:

Facilitated diffusion is a type of passive transport through the membrane, which involves the use of integral proteins called protein channels or transport proteins, and moves substances unable to cross the membrane by simple diffusion.

An example of facilitated diffusion through protein channels is the ion channel. Ions, being electrically charged particles, cannot pass through the plasma membrane. A protein channel -which crosses the whole thickness of the membrane- constitutes a space where ions can move depending on their concentration gradient.

In facilitated diffusion, both protein channels and transport proteins do not require energy, so it is a transmembrane passive transport process.

Answer:

Abiotic factor: Water | Biotic factor: Trees

Explanation:

Abiotic factors are non-living components within an ecosystem. Biotic factors are living organisms within an ecosystem. By removing the abiotic factor, water, an ecosystem will drastically decline. Just like humans, plants and animals depend on water. When drought hits, food supplies can be reduced and habitat compromised. Damage may be temporary, and habitat and food supplies may return to normal once the drought is over. By removing the biotic factor, trees, an ecosystem will suffer from material loss and climate change. Without trees, the land would be hot and dry, and dead trees would inevitably lead to large wildfires. This causes sun-blocking soot to blanket the skies, leading to years of crop failure and global famine.

1. The pharynx is located between segments of the respiratory and digestive systems.

The pharynx is a muscular tube that serves as a common pathway for both air and food. It is located at the back of the throat and connects the nasal and oral cavities to the esophagus and larynx. The pharynx is divided into three regions: the nasopharynx, oropharynx, and laryngopharynx.

The nasopharynx is located behind the nasal cavity and above the soft palate. It serves as a passageway for air, connecting the nasal cavity to the rest of the respiratory system. The oropharynx is located behind the oral cavity and extends from the soft palate to the epiglottis. It plays a role in both the respiratory and digestive systems, as it serves as a passage for both air and food. The laryngopharynx is the lowest part of the pharynx and is located behind the larynx. It leads to the esophagus for food passage and the larynx for air passage.

The pharynx plays a crucial role in the process of swallowing. When food is swallowed, it passes through the pharynx before entering the esophagus for digestion. The pharyngeal muscles contract in a coordinated manner, pushing the food bolus downward and preventing it from entering the airway.

In summary, the pharynx is located between segments of the respiratory and digestive systems. It acts as a common pathway for both air and food, playing a vital role in swallowing and directing the passage of substances into the appropriate pathways of the respiratory and digestive tracts.

Explanation:

The most significant anthropogenic sources of nitrogen compounds in the environment are the combustion of fossil fuels and nitrogenous fertilisers used in agriculture.

The growth and reproduction of plants depend on nitrogen. Growth of pasture and crops will frequently respond to an increase in soil nitrogen supply. Fertilizers containing nitrogen are frequently added to this scenario to regulate it.

Strong greenhouse gas nitrous oxide contributes between 5% and 7% of worldwide greenhouse gas emissions, 90% of which come from agricultural operations. The main sources of nitrous oxide emissions on farms are nitrogen-based fertilisers and livestock manure (dung and urine).

The most significant impact on reducing nitrous oxide losses comes from products that capture nitrogen more effectively. This also reduces ammonia volatilization to the atmosphere, as well as nitrate leaching.

Water flows through plants during transpiration, where it is then released as water vapour into the atmosphere. It mostly happens in the leaves of plants and is fueled by a number of processes.

Such as water uptake by roots, water transport through vascular systems, and water vapour diffusion from stomata (tiny openings on the surface of leaves). Water is transported through the plant's xylem vessels during transpiration from the roots to the leaves. Once inside the leaves, water evaporates from the cell surfaces of the plants and diffuses into the atmosphere through the stomata. This procedure not only helps the plant move water and nutrients around, but it also keeps the plant cool and preserves its structure.

As it helps to transfer water from the ground into the atmosphere, transpiration is a crucial part of the water cycle. As it has the ability to change the temperature and humidity of the surrounding air, it also contributes to regulating the climate.

Gas exchange with the cells takes place at the tracheal system of insects. In insects, gaseous exchange takes place through a series of tubes called the tracheal system.

Spiracles are the little holes seen on an insect's body's sides. The spiracles allow oxygen-rich air to enter. The tubes' network is joined by the spiracles. The air sacs, or alveoli, are located at the end of the bronchioles, the tiniest branching of the bronchial tubes.

The tiny air sacs called ALVEOLI are where oxygen and carbon dioxide are exchanged. In insects, the complex tracheal system, a tubular respiratory system filled with air, is principally responsible for gas exchange. Cuticular cell invasions that form branching tubes are called tracheae.

The genotype ll ww hh represents a triple homozygous recessive individual, meaning that all three genes are present in their homozygous recessive state.

If we cross this individual with another triple homozygous recessive individual, all of the F1 offspring will also be triple homozygous recessive. When we self-cross the F1 individuals to generate the F2 generation, we will get a 1:2:1 ratio of homozygous recessive: heterozygous: homozygous dominant individuals for each gene separately. Therefore, the proportion of F2 individuals that will have the same phenotype as the ll ww hh genotype will be 1/4, or 0.25. This means that approximately 25% of the F2 individuals will have the same phenotype as the triple homozygous recessive individual.

The renal artery carries blood to the kidney and branches into smaller vessels until it reaches the nephrons. The nephrons are the functional units of the kidney where blood is filtered. The afferent arteriole brings blood to the glomerulus, a network of capillaries surrounded by a capsule. The glomerulus filters out water and waste products from the blood and sends them to the tubule. The efferent arteriole takes the filtered blood away from the glomerulus and forms a second capillary network around the tubule. The tubule reabsorbs water and nutrients from the filtrate and returns them to the blood. The waste products are concentrated in the urine, which drains into the collecting ducts. The urine then flows into the renal pelvis and exits the kidney through the ureter. The renal vein collects blood from the kidney and returns it to the inferior vena cava.

Renal artery is a blood vessel that carries clean blood from the heart to the kidneys. The renal artery branches from the abdominal aorta and enters the kidney through the hilum. The renal artery plays an important role in maintaining normal blood pressure and kidney function.

Cellular respiration is a chemical process that occurs in the cells of all living organisms. It involves the breakdown of food molecules, such as glucose, and the subsequent production of energy in the form of ATP (adenosine triphosphate)

The process can be broken down into a few key steps:

Glycolysis: In the cytoplasm of the cell, glucose is broken down into two molecules of pyruvate, releasing a small amount of energy in the form of ATP and NADH (nicotinamide adenine dinucleotide).

Transition reaction: The pyruvate molecules then enter the mitochondria, where they undergo a transition reaction, which converts them into acetyl-CoA. This step also releases a small amount of energy in the form of ATP and NADH.

Citric Acid Cycle: Acetyl-CoA enters the citric acid cycle, where it is broken down further, releasing more energy in the form of ATP, NADH, and FADH2 (flavin adenine dinucleotide).

Electron Transport Chain: The NADH and FADH2 molecules produced in the previous steps are then used in the electron transport chain, which occurs in the inner membrane of the mitochondria. Here, electrons are transferred to oxygen molecules, which results in the production of water and the release of a large amount of energy in the form of ATP.

Answer: The nervous system plays a crucial role in coordinating and modulating various aspects of reproduction, including sexual behavior, hormone production, and reproductive physiology.

Explanation:  The relationship between reproduction and the nervous system can be understood in terms of the control and regulation of reproductive processes by the nervous system.

The nervous system, specifically the brain, plays a crucial role in sexual behavior by combining sensory information, emotions, and mental processes. It regulates the release of hormones and neurotransmitters, which affect sexual arousal, desire, and mating behaviors.

The autonomic nervous system plays a role in reproductive physiology by controlling physiological reactions related to reproduction. The sympathetic division triggers the "fight-or-flight" response, which may momentarily limit reproductive activities during stressful situations. On the other hand, the parasympathetic division promotes relaxation and is involved in sexual desire and erection.

The nervous system is absolutely essential in effectively managing and organizing the complex reproductive processes that are absolutely critical for the survival and perpetuation of a given species.
