Explanation:

Approximately 10 ATP or GTP equivalents will be produced from fuel molecules during one turn of the citric acid cycle.

The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid (TCA) cycle, is a central metabolic pathway in cellular respiration. It takes place within the mitochondria and is responsible for the oxidation of acetyl-CoA derived from various fuel molecules, such as glucose, fatty acids, and amino acids.

During one turn of the citric acid cycle, which involves a series of enzyme-catalyzed reactions, several high-energy molecules are produced. These include three molecules of NADH, one molecule of FADH2, and one molecule of GTP (guanosine triphosphate), which can be used to generate ATP.

NADH and FADH2 are electron carriers that participate in the electron transport chain, which ultimately leads to the production of ATP through oxidative phosphorylation. Each NADH molecule can generate approximately three ATP molecules, while each FADH2 molecule can generate approximately two ATP molecules.

In addition, one molecule of GTP can be converted to one molecule of ATP, thus contributing to the total ATP production. Therefore, considering the three molecules of NADH and one molecule of GTP produced during one turn of the citric acid cycle, approximately 10 ATP or GTP equivalents can be generated from fuel molecules.

The three main stages of wound healing are: Inflammatory phase , Proliferative phase, Maturation phase

Inflammatory phase: This stage begins immediately after the injury and lasts for several days. During this stage, the body's immune system responds to the injury by sending white blood cells to the site of the wound to fight infection and remove any debris. Proliferative phase: This stage begins a few days after the injury and can last for several weeks. During this stage, new tissue is generated to fill the wound. The wound begins to granulate, with new blood vessels forming to bring oxygen and nutrients to the site. Maturation phase: This stage begins several weeks after the injury and can last for up to two years. During this stage, the new tissue that was formed during the proliferative phase is remodeled and strengthened. Collagen fibers reorganize and align in the direction of stress, making the new tissue stronger.  These stages of wound healing are interdependent and overlap to some degree, and a variety of factors, such as age, nutrition, and underlying health conditions, can affect the healing process.

Explanation:

Tree pollen is a common hay fever trigger. It’s the first pollen to be released during hay fever season, and levels are typically highest from late March to mid-May.

Around 95% of people’s hay fever is triggered by grass pollen, which tends to be highest between mid-May and July. In fact, there’s strong evidence that when grass pollen levels are high, people with asthma are more likely to need hospital treatment.

Hay fever can also be triggered by weed pollen, which is highest from the end of June until September.

Know your pollen triggers

You can be allergic to more than one kind of pollen across the year. Different pollens are released at different times, but our changeable weather makes it hard to predict exactly when. If you have hay fever symptoms all year round you might have non-allergic rhinitis.  

If you regularly get hay fever and take antihistamines, start taking them up to four weeks before you normally get symptoms. Starting them early means that when pollen starts being released, the medication has already built up in your bloodstream so you may be less likely to react.

If you usually use a steroid nasal spray, it can take up to two weeks to start working, so again, start using it before your personal pollen trigger is released.

Answer:

Bears and lizards are more closely related.

Explanation:

The chart shows the branches of the species. The relativity of each species to each other shows how closely related they are.

organisms that are placed close to each other and have a nearly common ancestor have some similarities, so the bear and the lizard are closer to each other than the newt because they are closely present in the cladogram.

The cladogram is the diagrammatic representation of the animals and shows how the organisms have evolved and their special traits. This cladogram explains how the species show commonness and difference, such as the bear and the chimpanzee, which are both derived from the common mammal ancestor.

From the common amneote ancestor, the lizard, bear, and chimpanzee are descended, so they all have the traits of the amneote. From a common tetrapod ancestor, the newt, the lizard, the bear, and the chimpanzee are derived, and all have some characteristic of the tetrapoda.

Hence, the bear and the lizard are closer to each other than the newt because they are both present closely in the cladogram.

Answer:

The bright coloration and elaborate tail feature of the male peacock are thought to be examples of sexual selection. Sexual selection is a type of natural selection that occurs when certain traits are favored by members of one sex (usually females) when choosing a mate. These traits are often exaggerated or highly visible, and they serve to attract the attention of the opposite sex.

Answer:

In many species, including peacocks, males tend to have more colorful and elaborate physical features than females. This is often referred to as sexual dimorphism. One theory for the evolution of these differences is that they function as a form of sexual selection, in which the more attractive or ornamented individuals are more likely to attract mates and reproduce.

In the case of peacocks, the bright colors and elaborate tail feathers of the male may serve as a visual display that attracts females and signals the male's fitness and genetic quality. The bright colors and elaborate tail may also serve as a way for the male to advertise his presence to other males and potentially deter them from competing for the same females.

Overall, the bright coloration and elaborate tail of the male peacock may have evolved as a way for males to stand out and attract mates, which can increase their reproductive success.

A key defining feature of endocrine pathways is that they elicit rapid and robust changes to the body's physiology. Endocrine pathways are a vital part of the human body and are responsible for the communication and regulation of body functions. Endocrine pathways have distinct characteristics that distinguish them from other body pathways.

The hormones, which are the chemical signals of endocrine pathways, are released by glandular cells into the bloodstream, from which they reach their target organs or tissues.The hormones bind to specific receptors located on the plasma membrane of their target cells and exert their effects by initiating a cascade of intracellular signaling pathways. The binding of a hormone to its receptor results in changes in gene expression, metabolism, or other physiological processes that are critical to the regulation and homeostasis of the body.

The response to hormone signaling is usually rapid and robust, which allows for quick adaptation to changes in the environment. In conclusion, the answer to the question is that a key defining feature of endocrine pathways is that they elicit rapid and robust changes to the body's physiology.

Anabolism and catabolism are two opposing metabolic processes in living organisms. Anabolism is the process of building complex molecules from simpler ones, while catabolism is the process of breaking down complex molecules into simpler ones.

In anabolism, the body uses energy to synthesize complex molecules like proteins, nucleic acids, and polysaccharides from simpler molecules like amino acids, nucleotides, and monosaccharides. This process requires energy and is usually used for growth, repair, and maintenance of the body.

In catabolism, the body breaks down complex molecules like proteins, nucleic acids, and polysaccharides into simpler ones like amino acids, nucleotides, and monosaccharides. This process releases energy which can be used for various physiological functions like muscle contraction, cellular respiration, and body temperature regulation.

In summary, anabolism and catabolism are two opposing processes that occur in living organisms. Anabolism builds complex molecules from simpler ones and requires energy, while catabolism breaks down complex molecules into simpler ones and releases energy.
