of the following, which explains why the zooplankton also dipped during the same year and then seemed to cycle over the next three years? a.The zooplankton rely on the same nutrients for energy harvesting as the phytoplankton, So their population was also unable to acquire the necessary energy to maintain their population level. After that major dip there were enough nutrients for both categories of plankton b.Zooplankton are more temperature-sensitive than the phytoplankton, so the annual seasonal changes will affect their population sizes in a cyclical fashion. There was a sudden, extreme temperature change in the first dip that also affected the phytoplankton c.A migration of whales was blown off course by a storm one year and ate most of the phytoplankton and zooplankton. In the following years the whales returned to their normal migration route d.The reduction in the phytoplankton population meant that the zooplankton's energy source was drastically reduced, leading to the decrease in the zooplankton population size. After the dip the phytoplankton provided a steady energy source, and the zooplankton population fluctuated around its carrying capacity
Answers
The correct answer which explains why the zooplankton also dipped during the same year and then seemed to cycle over the next three years is d. The reduction in the phytoplankton population meant that the zooplankton's energy source was drastically reduced, leading to the decrease in the zooplankton population size.
After the dip, the phytoplankton provided a steady energy source, and the zooplankton population fluctuated around its carrying capacity. Zooplankton rely on phytoplankton for their energy source, so when there is a dip in the phytoplankton population, it directly affects the zooplankton population. Once the phytoplankton population recovers, the zooplankton population will also start to increase again, leading to a cyclical pattern.

In addition to these two key characteristics, this group possesses a group of embryonic cells called the ____________ that contribute to the development of many vertebrate features.
Answers
The group of embryonic cells that contribute to the development of many vertebrate features is called the neural crest.
The neural crest is a transient structure that forms during embryonic development in vertebrates. It arises from the dorsal region of the neural tube, which is a structure that eventually gives rise to the central nervous system. The neural crest cells migrate extensively throughout the embryo and give rise to a wide range of cell types and tissues.
The neural crest cells have a remarkable ability to differentiate into various cell types, such as sensory neurons, melanocytes (cells responsible for skin and hair color), cartilage and bone cells, smooth muscle cells, and certain types of connective tissue. This diverse range of cell types gives rise to many important features in vertebrates, including the craniofacial skeleton, peripheral nervous system, and certain glands.
The migration and differentiation of neural crest cells are tightly regulated by a combination of genetic and environmental factors. Defects in neural crest cell development can lead to a variety of developmental disorders and birth defects, such as craniofacial abnormalities, heart defects, and certain types of cancer.

Answers
If a student scores in the 97th percentile of a normally distributed set of scores, this means that the student's score was approximately 1.88 standard deviations above the mean.
In a normally distributed set of scores, the mean, median, and mode are all equal. The scores are distributed symmetrically around the mean, with 68% of the scores falling within one standard deviation of the mean, 95% of the scores falling within two standard deviations of the mean, and 99.7% of the scores falling within three standard deviations of the mean.
The 97th percentile corresponds to a z-score of 1.88, which means that the student's score was 1.88 standard deviations above the mean. This can be found using a z-score table or calculator.
Therefore, if a student scores in the 97th percentile of a normally distributed set of scores, this means that the student's score was approximately 1.88 standard deviations above the mean.

Conservation practices
may cause yields to increase and therefore provide more fish
will cause yields to decrease and therefore conserve fish
will cause yields to remain constant for many years
created a commission to study fish biology
Answers
Conservation practices may cause fish yields to vary, potentially leading to an increase, decrease, or a constant yield depending on the specific measurements implemented.
Conservation practices can address some of these factors by improving habitat quality, reducing pollution, controlling invasive species, restoring wetlands or other important habitats, and implementing sustainable fishing practices. Some of these practices may have a direct or indirect positive impact on fish yields by increasing the overall health and productivity of the ecosystem. For example, reducing nutrient runoff into a river may lead to more algae growth, which can support more fish.
If the conservation practices focus on sustainable fishing methods and proper habitat management, yields may increase over time as fish populations recover and become more robust. In some cases, conservation practices may lead to a decrease in yields, particularly if strict regulations or catch limits are imposed to conserve fish populations in the short term. When conservation practices successfully balance both the needs of the fish populations and the fishing industry, yields may remain constant for many years, providing a sustainable source of fish.

Nombra de forma ordenada el camino que recorre el CO2 desde el capilar sanguíneo que rodea el alveolo hasta salir del cuerpo.
Answers
Answer:
El aire ingresa al cuerpo a través de la boca o la nariz y se mueve rápidamente hacia la faringe o la garganta. Desde allí, pasa a través de la laringe o laringe y entra en la tráquea.
La tráquea es un tubo fuerte que contiene anillos de cartílago que evitan que se colapse.
Dentro de los pulmones, la tráquea se ramifica en un bronquio izquierdo y derecho. Estos se dividen aún más en ramas cada vez más pequeñas llamadas bronquiolos.
Los bronquiolos más pequeños terminan en diminutos sacos de aire. Estos se llaman alvéolos. Se inflan cuando una persona inhala y se desinflan cuando una persona exhala.
Durante el intercambio de gases, el oxígeno pasa de los pulmones al torrente sanguíneo. Al mismo tiempo, el dióxido de carbono pasa de la sangre a los pulmones. Esto sucede en los pulmones entre los alvéolos y una red de pequeños vasos sanguíneos llamados capilares, que se encuentran en las paredes de los alvéolos.
Aquí puede ver los glóbulos rojos que viajan a través de los capilares. Las paredes de los alvéolos comparten una membrana con los capilares. Eso es lo cerca que están.
Esto permite que el oxígeno y el dióxido de carbono se difundan o se muevan libremente entre el sistema respiratorio y el torrente sanguíneo.
Las moléculas de oxígeno se adhieren a los glóbulos rojos, que viajan de regreso al corazón. Al mismo tiempo, las moléculas de dióxido de carbono en los alvéolos salen del cuerpo la próxima vez que una persona exhala.
El intercambio de gases permite que el cuerpo reponga el oxígeno y elimine el dióxido de carbono. Hacer ambas cosas es necesario para sobrevivir.
Explanation:
Glacial advances in the past have been accompanied by increased CO2 levels.
t/f
Answers
True. Glacial advances and retreats are often linked to changes in atmospheric CO2 levels. During glacial periods, CO2 levels were lower due to increased storage in oceans and decreased emissions from sources such as volcanoes.
As temperatures cooled, ice sheets expanded and reflected more sunlight, further cooling the planet. However, during periods of warming and glacial retreat, CO2 levels increased due to the release of carbon stored in soils and oceans. This led to a positive feedback loop, where warming temperatures led to increased CO2 levels, which in turn led to more warming. Today, human activities such as burning fossil fuels have caused a rapid increase in CO2 levels, contributing to the current warming trend and potential future glacial retreat.

A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?
Answers
Answer:
Cellular respiration
Explanation:
Herbivores are organisms that feed on plant materials solely. They are usually animals like sheep, cattle, goats with four stomach compartments. They are part of the global carbon cycle which shows how carbon is circulated in nature.
Plant matter is broken down by herbivores through a series of metabolic steps. The final product is a glucose laden material which is the raw material needed for cellular respiration. When oxygen combines with the glucose, energy is liberated, and carbon dioxide, a waste product is released into the atmosphere. This way, carbon is cycled in the ecosystem.Answer:
Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.

control of parathyroid hormone release label the feedback mechanism that regulates parathyroid hormone release.
Answers
The control of parathyroid hormone release is a finely-tuned negative feedback mechanism that ensures the proper balance of calcium in the blood.
The release of parathyroid hormone is regulated by a negative feedback mechanism. When the levels of calcium in the blood decrease, the parathyroid glands release parathyroid hormone, which acts on the bones, kidneys, and intestines to increase calcium levels in the blood. As the calcium levels rise, this signals the parathyroid glands to stop releasing more parathyroid hormone, thus restoring the balance of calcium in the blood.
This feedback mechanism is crucial for maintaining healthy levels of calcium in the body. If the parathyroid glands release too much parathyroid hormone, it can lead to hypercalcemia, which can cause fatigue, muscle weakness, and kidney stones. On the other hand, if the parathyroid glands release too little parathyroid hormone, it can lead to hypocalcemia, which can cause muscle cramps, seizures, and even cardiac arrest.
