Explanation:
cianobacteria is célula procariota?
The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Answer:
(A) RNA like DNA is a carrier of genetic information and contains the nitrogen bases adenine, guanine and cytosine.
Explanation:
RNA is a single stranded molecule which is replicating molecule that plays its role evolution of different stages. DNA is double stranded molecule that is stable under alkaline conditions and perform various functions in different body parts. RNA provides template on which DNA nucleotides assemble.
Answer:
true. there is more precipitation when it is very very cold.
Explanation:
Answer:
B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Explanation:
Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.
According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.
Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.
