Answer:

Cognitive behavioral therapy (CBT) is the most widely-used therapy for anxiety disorders. Research has shown it to be effective in the treatment of panic disorder, phobias, social anxiety disorder, and generalized anxiety disorder, among many other conditions.

The treatment that is commonly used to manage stress and anxiety that are related to a disorder is meditation, which is the third option. The mediation helps the person recover from the stressful situation.

The mental disorder is linked to the person's personal experience; for example, if the person has had any negative experiences and is unable to cope with them, the person is more likely to enter the anxiety and depression stages. These types of mental disorders can harm a person physically too, as the nervous system does not work properly, and due to this neuronal imbalance, the digestive system, sleep cycle, and cardiac health will all be affected.

Meditation can be used as a form of therapy for the individual. Because in meditation, a person is told to practice concentration on mental health by many different methods, and eventually a person gets better with time.

Hence, The treatment that is commonly used to manage stress and anxiety that are related to a disorder is meditation, which is the third option.

Answer:

Cells use a molecule called ATP  to store and release energy like a battery. The energy is stored in chemical bonds between phosphate  groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

ATP (adenosine triphosphate) can be though of as a battery. It is also sometimes desribed as the energy currency of the cell. DNA and RNA are nucleic acids - the genetic information of the cell, and does not store and release energy. CMP is a nucleotide.

The energy found in ATP is found stored between phosphate groups of the molecule. When a phosphate group is released, it forms ADP (adenosine diphosphate)

Cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.

ATP is the energy coin of the cell whose hydrolysis is used to carry out many different metabolic functions (e.g., reproduction, differentiation, growth, etc).

ATP hydrolysis is a catabolic reaction, which provides releasable energy stored in the bonds between the second and third phosphate groups.

The molecule of ATP can transfer its energy to different molecules during many cellular processes such as, for example, DNA replication, active transport, muscle contraction, etc.

In conclusion, cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.

The plant will swell and possibly burst if the cell walls are weak. So, the correct option is A.

A cell wall is an external structural layer that surrounds some types of cells. It may be hard, flexible, or occasionally rigid. It serves as a filtration system as well as structural protection and support for the cell. The cell wall composition varies according to the organism which is permeable in nature

The cell wall isolates the inner elements from the surrounding environment. The cell as well as its organelles are also development in the context, support, and protection by it. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component. If the plant's cell walls are insufficient in the case above, it will enlarge and possibly burst.

Answer:okay so I did it it was very fun so here are my results EXPERIMENTAL DATA  Before After 24 hours

Explanation: Conclusion

The conclusion to this test is that the plastic bag is permeable to iodine. The result

of this experiment clearly answers the "Problem" as stated above. This is~ by

the fact that the starch solution (dependent variable) in the baggie turned purple,

indicating the presence of iodine (independent variable) in the mixture. The starch

solution is the dependent variable because its color is affected by the iodine

solution. M.y hypothesis was that the iodine will get into the bag of starch because

the baggie is permeable to iodine. If the iodine solution penetrates the bag, it will

turn the starch solution inside the baggie, purple. The control data chart above

shows that if the starch had not been immersed in the iodine solution, but rather a

water solution, it would have remained the same color, white. Obviously, in order

for the iodine to enter the starch solution, the baggie must be permeable to the

iodine. The baggie represents a cell membrane. This lab is meant to demonstrate

whether or not a cell membrane is permeable to substances. Cell membranes of

living organisms may be permeable to some substances, but not permeable to other

substances. In this experiment,'1..charted that the iodine solution in the beaker did

not turn purple. This means that the starch solution did not penetrate the baggie

and therefore did not mix with the iodine outside the baggie. Because of this data, it

is clear that the plastic baggie is not permeable to starch, but is permeable to iodine.

In a cell membrane, this is called selective permeability. In other words, the iodine

can go through the baggie, but the starch cannot. The purpose of this experiment is

to show that a cell membrane is a type of barrier, and is permeable to some

substances, but may not be permeable to all substances. Therefore, a cell membrane

is selectively permeable.

Equation

Explanation:

the last word is Equation

Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical​ equation.

A chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.

In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.

Chemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.

Answer:

The complete explanation of the  immune response to a pathogen through the oral (oral-anus) and respiratory route is given below in explanation part .

Explanation:

In order to provide host protection against pathogens wherever they can enter or spread, the immune system can be seen as an organ distributed throughout the body. A collection of anatomically distinct compartments can be distinguished within the immune system, each of which is specifically adapted to produce a response to pathogens present in a specific set of body tissues. The basic concepts underlying the initiation in the compartment of the peripheral lymph nodes and spleen of an adaptive immune response. This is the compartment that responds to antigens that have dispersed through the blood or penetrated the tissues. The mucosal immune system (commonly represented by the MALT) is a second compartment of the adaptive immune system of equal size to this, and situated near the surfaces where most pathogens enter. Body cavities (peritoneum and pleura) and skin are two other distinct compartments. These compartments are characterized by two main characteristics. The first is that immune responses induced within one compartment are generally restricted to that specific compartment in terms of speech. The second is that by expressing homing receptors that are bound by ligands, known as addressins, which are specifically expressed within the tissues of the compartment, lymphocytes are limited to particular compartments. The body's mucosal surfaces are particularly susceptible to infection. Because of their physiological roles in gas exchange (the lungs), food absorption (the gut), sensory roles (eyes , nose , mouth, and throat), and reproduction (uterus and vagina), they are thin and permeable barriers to the interior of the body. Obvious susceptibility to infection is provided by the need for permeability of the surface lining of these sites and it is not surprising that the vast majority of infectious agents via these routes enter the human body.

When contemplating the immunobiology of mucosal surfaces, a second essential aspect to bear in mind is that the gut serves as a conduit of entry in the form of food to a large array of foreign antigens. The immune system has developed mechanisms to prevent, on the one hand, a robust immune response to food antigens and, on the other, to detect and destroy the entry of pathogenic organisms via the gut. The majority of the gut is heavily colonized by commensal microorganisms, which live in symbiosis with their host, to further complicate matters. In certain ways, these bacteria are beneficial to their hosts. They provide protection by occupying the ecological niches for bacteria in the gut against pathogenic bacteria. By synthesizing vitamin K and some of the components of the vitamin B complex, they also serve a nutritional role in their host.

Peyer's patches of the small intestine, the appendix, and solitary lymphoid follicles of the large intestine and rectum are the other major sites inside the gut mucosal immune system for the activation of immune responses. The patches of Peyer are an extremely important location in the small intestine for the activation of immune responses and have a distinctive shape, forming domelike structures that reach into the intestinal lumen. Specialized epithelial cells reside in the overlying layer of follicle-associated epithelium of the Peyer's patches. Instead of the microvilli present on the absorptive epithelial cells of the intestine, they have microfolds on their luminal surface and are known as microfold cells or M cells. By endocytosis or phagocytosis, M cells pick up molecules and particles from the gut lumen. This material is then transported to the basal cell membrane, where it is released into the extracellular space, via the interior of the cell in vesicles. This mechanism is referred to as transcytosis. The cell membrane of M cells is extensively folded at their basal surface around underlying lymphocytes and antigen-presenting cells that take up the transported material released from the M cells and process it for the presentation of antigen.

Answer:

Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don't use in your normal, day-to-day conversations.If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Answer:

> Consumers convert glucose from producers into ATP.

Explanation:

Consumers do NOT provide oxygen or glucose for producers.

The statement, consumers convert the glucose from producers into ATP. So the correct option is D.

In feeding chains, organisms are categorized into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.

Autotrophs, another name for producers, grow their own food. Every food chain's first level is comprised of these. Plants or single-celled creatures represent the majority of autotrophs. The majority of autotrophs produce their "food" (a nutrient called glucose) from sunlight, carbon dioxide, and water through a process known as photosynthesis.

The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live in volcanoes that are still active utilize sulfur compounds to make their own food. Chemosynthesis is the name of this process.

Therefore the correct option is D.
