The average volume of a red blood cell is 87 μ m 3 . The mean concentration of hemoglobin in red blood cells is 0.34 g ⋅ ml − 1

S_A_V [24]

Answer:

2.956 × 10 ⁻¹¹ g

Explanation:

The mean concentration of hemoglobin in red blood cell = 0.34 g/ml

average volume of a red blood cell = 87μ m³ where 1 μ m³ = 1 × 10 ⁻¹² ml

average volume = 87 × 1 × 10 ⁻¹² ml = 87 × 10 ⁻¹² ml

weight of hemoglobin contained in an average red blood cell = 87 × 10 ⁻¹² ml × 0.34 g/ml = 2.956 × 10 ⁻¹¹ g

Which food chain sequence can be found in this meadow?

Vikki [24]

Answer:

The correct answer is "grass -> grasshopper -> raccoon -> wolf"

Explanation:

Food chains are diagrams that represent the order at which organisms feed from each other, starting from producers that are able to make their own food, until quaternary consumers that feed from predators. In this case, the sequence of grass -> grasshopper -> raccoon -> wolf can be found in the meadow. Grass is a plant that function as producer, which is consumed by grasshopper (primary consumer), which is consumed by raccoon (secondary consumer), which is consumed by wolf (tertiary consumers). I attached the missing information in a picture.

Match each hazardous waste with its matching description.

Sphinxa [80]

Matching each hazardous waste with its description is shown below :

<u>Hazardous waste description</u>

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

Too much exposure to these hazardous waste always leave a negative effect on the health of individuals, Asbestos are used in the roofing of older buildings and can be found in older landfills. the fiber from asbestos affects the Lungs ( alveoli ) of humans which might lead to lung cancer.

Mercury are used for PC's backlight and also in the mother board of modern computers too much exposure to mercury can lead to brain damage.

Cadmium are hazardous cancer causing agent used in making industrial batteries, prolonged exposure to lead poses several health risk which includes reproductive issues because lead can cut across placenta barrier between a pregnant woman and unborn child.

Hence we can conclude that matching each waste to its description is as

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues
