Answer:
Influenza is a respiratory infection that is spread through contact with respiratory secretions from an infected person who is sneezing and/or coughing. illness—each year approximately 36,000 persons die as a result of complications of influenza and over 200,000 are hospitalized.
Explanation:
In a chemical reaction one or more reactants combine or react to form one or more product(s) with different chemical and physical properties.
When aqueous sodium sulfide reacts with aqueous copper(II) nitrate results in the formation of aqueous sodium nitrate and solid copper(ll) sulfide.
First, identify the chemical symbols for the elements in the compounds.
Sodium sulphide = 
Copper(II) nitrate = 
Sodium nitrate = 
Copper(II) sulfide = 
The chemical reaction is given as:
Now, balance the chemical equation:
For balance the equation, multiply by 2.
Thus,
Answer:
Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight.
Explanation:
Remember that <span>λ, or wavelength, is proportional to (1/f), where f=frequency. That means that wavelength and frequency are inversely related. When one goes up, the other goes down, and vice versa. That means answers C and D are incorrect because those answers have wavelength and frequency in a direct relationship.
Radiant energy is directly proportional to frequency. When frequency increases, radiant energy increases. That means A) </span><span>As wavelength decreases, radiant energy and frequency increase is the correct answer.</span>
Answer:
b consumers eat producers
Explanation:
In a food chain, the consumers are living organisms that eat organisms from a different population. Examples are herbivores like goats.
Producers make their own food in the food chain. Examples are plants.
The relationship between consumer and producers is hence that consumers consume / eat producers. Goats eat grass.
The correct option is;
b consumers eat producers
