Answer:

A) Decreases;increase

Explanation:

When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.

This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.

Plan an investigation to determine which part of the oregano plant has the highest concentration of chemicals with antimicrobial

Mkey [24]

Answer:

The study reported here presents a comparative screening of three medicinal plants including oregano (Origanum vulgare L.), lavender (Lavandula angustifolia) and lemon balm (Melissa officinalis) having the same geographical origin, the Southeast region of Romania, and growing in the same natural conditions. The contents of total phenolics and total flavonoids for the extracts of these were determined. Furthermore, the total antioxidant capacity was also evaluated. It was found that Origanum vulgare and Melissa officinalis extracts present the most effective antioxidant capacity in scavenging DPPH radicals, while Lavandula angustifolia is less active. High performance liquid chromatography-mass spectrometry analysis was used to identify the components of extracts. Major phenolic acids identified in the analysed species were ferulic, rosmarinic, p-coumaric and caffeic, while predominant flavonoids were quercetin, apigenin kaempherol, which were present as glucosides.

Assuming this is a healthy ecosystem, which organisms in this ecosystem would you expect to have the highest population? Which s

nekit [7.7K]

Answer:

1. Highest population: Primary producers (e.g. plants). In the case of animals: Primary consumers (e.g. grasshoppers).

2. Lowest population: Third-level consumers (Top predators). E.g. An eagle.

Explanation:

There are two types of ecological pyramids that illustrate the correlation between trophic levels and biomass in a healthy ecosystem:

Energy pyramid: illustrates the flow of energy at each trophic level. That is, energy is passed up from lower to higher.
Biomass pyramid: illustrates the amount of biomass at each trophic level. Less energy, less organisms.

In a healthy ecosystem, plants are located at the bottom of the pyramid because they produce their own food; while top predators are located at the top.

Plants (trees and bushes), for example, will have high population levels and will pass energy to the next level of the pyramid. As we go up the trophic levels, organisms tend to be larger in size but fewer in numbers. This means that the top predators or third-level consumers, such as eagles, lions, or bears, are indeed bigger but have lower biomass or population numbers.
