How is a varied diet an advantageous adaptation for animals dwelling in the chaparral biome?
Ray Of Light [21]
<span>The chaparral is characterized by sparse, rough terrain and nutrient-poor soil meaning that no single resource is overly abundant. Therefore, a varied diet allows an animal to make use of a wider selection of the resources that are available to it and thereby thrive.</span>

As evidenced in the graph, the national average CO concentrations have decreased substantially over the years. All BUT ONE tacti
Gekata [30.6K]

Answer:

Explanation:

Carbon monoxide (CO) is a colourless, non-irritant, odourless and tasteless toxic gas. It is produced by the incomplete combustion of carbonaceous fuels such as wood, petrol, coal, natural gas and kerosene. Its molecular weight is 28.01 g/mol, melting point −205.1 °C, boiling point (at 760 mmHg) −191.5 °C (−312.7 °F), density 1.250 kg/m3 at 0 °C and 1 atm and 1.145 kg/m3 at 25 °C and 1 atm, and relative density (air = 1) 0.967 (1,2). Its solubility in water at 1 atm is 3.54 ml/100 ml at 0 °C, 2.14 ml/100 ml at 25 °C and 1.83 ml/100 ml at 37 °C.

The molecular weight of carbon monoxide is similar to that of air (28.01 vs approximately 29). It mixes freely with air in any proportion and moves with air via bulk transport. It is combustible, may serve as a fuel source and can form explosive mixtures with air. It reacts vigorously with oxygen, acetylene, chlorine, fluorine and nitrous oxide. Carbon monoxide is not detectable by humans either by sight, taste or smell. It is only slightly soluble in water, blood serum and plasma; in the human body, it reacts with haemoglobin to form carboxyhemoglobin (COHb).

The relationship of carbon monoxide exposure and the COHb concentration in blood can be modelled using the differential Coburn-Forster-Kane equation (3), which provides a good approximation to the COHb level at a steady level of inhaled exogenous carbon monoxide.

Conversion factors

At 760 mmHg and 20 °C, 1ppm = 1.165 mg/m3 and 1 mg/m3 = 0.858 ppm; at 25 °C, 1 ppm = 1.145 mg/m3 and 1 mg/m3 = 0.873 ppm.

Are there ways you can help reduce the use of nonrenewable resources? If so, how?PLEASEEEEEEEEEEEEEEE HELPPPPPPOPO MEEEEEEEEEEE
irinina [24]

Answer:

The three R's – Reduce, Reuse and Recycle – represent the best strategy for conserving non-renewable oil, coal and natural gas. ... Increasing the reliance on renewable energy sources, such as solar, wind and geothermal generators, can also help conserve the dwindling supplies of fossil fuels that remain in the ground.

What is the best way to show the lead levels in six contaminated water wells?
Marrrta [24]

Answer:

Option B, Barr graph

Explanation:

A bar graph is used for comparing several items all together based on any certain parameter.  

Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.  

A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.

Hence, option B is correct
