The best answer is "a" - the overuse of antibiotic.
Emerging disease are those whose incidence has increased in the past two decades or threatens to increase in the near future.
Such diseases include :
1. Old infections emerging as a result of antimicrobial resistance due to indiscriminate or poor use or over use of antibiotics.
2. New infections resulting from evolution or change of existing organisms.
3. Previously unrecognized infections in areas undergoing ecological transformation
4. Known infections spreading to new geographical areas or population.
Antibiotic resistance has been on the rise and is now major concern.
Answer:
The correct answer will be option- A
Explanation:
Red drop effect is the effect observed by the light present in the spectrum of the wavelength of red light. The effect is observed with the decrease in the quantum yield of the oxygen formed per quantum of light when the wavelength of light exceeds 680 nm.
The decrease of quantum yield is observed due to the fact that the oxygen is formed by the breakdown of the water molecule during light-dependent reaction which is initiated by the PS II which begins the chain at 680nm.
If light exceeds the 680 nm then, PS II will remain inactive and thus will abrupt the dissociation of the water molecule and thus the formation of oxygen during the light-dependent phase.
Thus, option-A is the correct answer.
Answer:
the null hypothesis and the alternative hypothesis.
Explanation:
null contains a statement of equality (greather than or equal to, less than or equal to, equal to) and the alternative is the complement of the null hypothesis statement that must be true if H0 is false and it contains a statement of strict inequality (greater than, less than, not equal to)
Answer:
1. Newton believed that gravity was a force.
3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Explanation:
Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.
To solve the problem, let us note that the calcium percentage no longer considers the moisture content of the canned dog food. Taking the 75% of the sample 681 grams results in a moisture content of 510.75. This is "removed" from consideration and we're left with 170.25 grams which we multiply with the given (dry basis) percentage of calcium to get 2.043 grams of Calcium.
