Hormonal factors, specifically estrogen, may play a role in the late onset of schizophrenia in women. Option B is correct.

Estrogen has been suggested to have a protective effect against the development of psychotic symptoms before menopause. During the reproductive years, estrogen levels are relatively high in women, and it has been proposed that this hormone may have a neuroprotective effect on the brain, influencing neurotransmitter systems and reducing the risk of psychosis.

After menopause, estrogen levels decline significantly, which may contribute to the increased susceptibility to schizophrenia in older women. The loss of estrogen's protective effects may leave the brain more vulnerable to the development of psychotic symptoms. The relationship between hormonal factors and schizophrenia is complex and not fully understood. Option B is correct.

Only about 10% of energy is transferred from one trophic level to another, and 90% is lost as heat.

When organic molecules from one organism 's body are ingested by another, energy can be transferred from one trophic level to the next. However, energy transfer among trophic levels is typically inefficient.

When organisms from one trophic level are ingested by organisms from the next level, energy is lost as metabolic heat. The amount of energy transferred between trophic levels is measured by trophic level transfer efficiency (TLTE).

Only about 10% of the energy moves from one trophic level to the next. The remainder is used for organism life processes, while a portion is absorbed as heat.

spider web is not a living thing

It is false that the spider web is basically considered a biotic factor.

A living thing that alters its surroundings is referred to as a biotic factor. Examples of organisms found in a freshwater habitat include algae, fish, amphibians, and aquatic plants.

A particular ecosystem is the result of the interaction of biotic and abiotic components.

Animals, plants, fungus, bacteria, and protists are examples of biotic factors. Water, soil, air, sunlight, temperature, and minerals are some abiotic examples.

All the organisms in the ecosystem have a relationship with biotic variables. The biological byproducts they produce and their presence alter an ecosystem's structure.

All living things, including people, fungi, and bacteria as well as animals and plants, are considered to be biotic factors.

Abiotic elements are those that are not living, such water, soil, and atmosphere. In an ecosystem, how these elements interact is crucial.

As a result, over 50 percent of the world's coral reefs have died in the last 30 years and up to 90 percent may die within the next century—very few pristine coral reefs still exist.

Explanation:

As a result, over 50 percent of the world's coral reefs have died in the last 30 years and up to 90 percent may die within the next century—very few pristine coral reefs still exist.

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.

Coral reefs are massive structures made of limestone deposited by coral polyps. Often referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species.

Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

The body reacts to stimuli in two basic ways: through neural and endocrine responses. A comparison of their speed, specificity, signal kinds, length of action, and coding of stimulus intensity is shown below:

Speed: Neural reflexes are distinguished by their quick speed of reaction. In general, endocrine reflexes have a slower reaction time.

Specificity: Neural reflexes frequently function in a more precise manner. The consequences of endocrine reflexes are frequently more pervasive.

Signal Types: Electrical signals (action potentials) sent by neurons are largely involved in neural responses. Hormonal chemical signals are the basis for endocrine reflexes.

Action Time: Neural reflexes normally take only a brief amount of time to complete. Endocrine responses frequently take longer to take effect.

Coding for Stimulus Intensity: In neurological reflexes, there are several techniques for encoding the frequency of action potentials. The quantity of hormone released into the bloodstream often serves as an indicator of the stimulus strength in endocrine responses.

Thus, rapid speed, specificity, reliance on electrical impulses, and relatively brief duration of action are characteristics of neural reflexes.

Explanation:

If a true-breeding brown-striped lizard is crossed with a true-breeding white-striped lizard and in the next generation, all of the lizards are brown-striped, then this outcome indicates that the brown stripe allele is dominant to the white stripe allele (option a).

A dominant allele gene variant is any genetic variant in a given locus that is expressed on a recessive asked allele to generate an individual having a characteristic phenotype even in individuals that are heterozygous for the gene.

However, a heterozygous individual can be denied as an organism that exhibits two different gene variants or alleles for a given genetic locus.

Therefore, with this data, we can see that a dominant allele gene variant is able to mask another gene variant or allele called the recessive allele in heterozygous individuals that have both gene variants.

The phospholipid bilayer is Steroid hormones that are lipid soluble and readily cross the phospholipid bilayer.

Since steroid hormones are lipid-derived hormones they can cross the plasma membrane by simple diffusion. This means it can pass through every cell in the body. Unlike other types of hormones, steroid hormones do not need to bind to plasma membrane receptors.

Steroid hormones produce changes inside the cell by first crossing the cell membrane of the target cell. Steroid hormones are able to do this because they are fat-soluble, unlike non-steroid hormones. Cell membranes are made up of phospholipid bilayers that prevent fat-insoluble molecules from diffusing into the cell. Steroids can freely diffuse through the lipid bilayer.

digestivo, respiratorio, circulatorio y excretor

Explanation:

El proceso de nutrición consiste en la ingesta de alimentos, los cuales son posteriormente transformados en energía y estructuras celulares que el organismo necesita para funcionar normalmente. Durante este proceso, intervienen cuatro sistemas:

- Sistema digestivo: descompone químicamente los alimentos en nutrientes. Los alimentos son sometidos a un proceso de fragmentación mecánica y digestión química. En primer lugar, los alimentos son triturados en la boca por los dientes, mezclados con saliva para formar un bolo alimenticio que llega al estómago donde los jugos gástricos los transforman en una papilla conocida como quimo. A continuación, los nutrientes llegan al intestino delgado donde son mezclados con el jugo pancreático y la bilis del hígado para ser absorbidos por la sangre. Finalmente, los compuestos que no fueron absorbidos llegan al intestino grueso donde se absorbe lo que queda de agua y lo demás es eliminado.

- Sistema respiratorio: los pulmones son los órganos encargado del proceso de respiración mediante el cual el organismo intercambia gases con el ambiente a través la sangre. De este modo el organismo obtiene oxígeno que es utilizado para oxidar los nutrientes obtenidos por el sistema digestivo.

- Sistema circulatorio: encargado de transportar nutrientes y oxígeno a las células del cuerpo y simultáneamente transportar elementos de desecho hasta los órganos del sistema excretor.

- Sistema excretor: encargado de eliminar los desechos de los alimentos. Los compuestos que no fueron digeridos en el intestino delgado llegan al intestino grueso donde se transforman en las heces las cuales son expulsadas por el ano. Por otra parte, el aparato urinario formado por los riñones y la vejiga urinaria funcionan para eliminar los desechos de la sangre a través de la orina.

In the Gi tract, a food bolus is converted into a semiliquid mass of partly digested food and digestive secretions known as chyme.

What is bolus?

Saliva combined with food after it has been chewed. Food particles are chemically reduced, hydrated for taste, and lubricated for easy swallowing when chewed to a size that can be easily swallowed. Saliva contributes digestive enzymes, water, and mucus that help in these processes.

What is digestive tracts?

At the end of glycolysis, two ATP molecules are produced as a net gain.

An anaerobic process called glycolysis occurs in the cytoplasm. It involves the conversion of two pyruvate molecules from glucose. To start this process, two ATP molecules are required.

As a result of glycolysis, four ATP molecules, two NADH molecules, and two molecules of pyruvate are produced. The two ATP molecules produced are used to offset the two ATP molecules that were initially used. This results in a net gain of two ATP molecules at the end of glycolysis.

The NADH molecules produced can be used in the electron transport chain to produce more ATP molecules. Therefore, glycolysis is a crucial metabolic pathway that produces energy in the form of ATP.

The group that can undergo photosynthesis to generate energy is 3. Producers.

Plants, algae, and some bacteria are capable of using sunlight energy to convert carbon dioxide and water into organic molecules through photosynthesis. Other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers, can use these organic molecules as a source of energy (carnivores).

Secondary and primary consumers are unable to generate their own energy through photosynthesis and must obtain energy from other organisms. As a result, options 1 and 4 are incorrect. Option 5, "none of these," is incorrect because primary producers can generate energy via photosynthesis.

Photosynthesis is the process by which primary producers like plants, algae, and some bacteria convert solar light energy into chemical energy stored in organic molecules like glucose. This method employs the use of specialised pigments, such as chlorophyll, to capture sunlight energy and use it to power a series of chemical reactions that convert carbon dioxide and water into organic compounds.
