Hello there!
The ship traveled 1300 kilometers in total. But, at rate of 90 kilometers per hour. So what is the rate of the ship for 1300 kilometers.
This is very easy my friend .... all you have to do is this
90 K >>>> 1 hour
1300 k >>>> x ( x represent the hour we are looking for)
Cross multiply
90x = 1300
Divide both sides by 90
90x/90 = 1300/90
x = 14.44 hr
Answer : It take the ship 14.44 hr to travel 1300 kilo
The correct option is D
Good luck and enjoy life!
Answer:
The correct answer is (1) digestive and circulatory
Explanation:
Digestive system helps in digestion of complex organic matter present in the food like polysaccharides, proteins, lipids, etc. So due to the function of the digestive system, these complex molecules are converted into simpler forms like glucose, amino acids, etc. Then these simpler forms are absorbed in the body through intestine.
Ribosomes help in the production of proteins which requires amino- acids so the absorbed amino acids are moved into the cells through the circulatory system. Therefore digestive system and circulatory system provide the molecules required for metabolic activities.
Answer:
C. Substrate
Explanation:
In the Lock and Key Theory it is the specific action of an enzyme with a single <u>substrate</u> which can be explained as the lock and key theory in biology.
Answer: Coal
, Wood, Wind turbines
Explanation:
Coal is a nonrenewable resource. It can be used for the generation of electricity as the burning of the coal as fuel liberates immense heat energy depending upon the carbon content of the coal. The amount of energy liberated by the coal depends upon the type of coal used hence, the energy yield can remain unpredictable. Wood is the source of biomass energy. It can be burned upon to obtain heat energy. The energy produce depends upon the carbon content and weight of the wooden logs used.
The energy harnessed by a wind turbine is also unpredictable because in a hot humid day and a wet rainy day wind energy cannot be captured.
