Answer:
66.7m/s²
Explanation:
initial velocity(V)=54m/s
Final velocity(U)=4m/s²
Time taken(t)= 0.75 seconds
Acceleration is unknown
To find the acceleration we use this formula
a=v-u/t
a=54-4/0.75
a=50/0.75
a=66.666666
since it is acceleration we use the symbol m/s² after approximating to 1 decimal place
a=66.7m/s²
rate The answer as brainliest
The risk of lung cancer death is no different between medium, low, and very low-tar cigarettes.
People who smoke low-tar cigarettes compensate the lack of tar by changing their breathing habits, for example, they will take deeper drags or hold the smoke in for a longer period of time, basically negating the supposed " low-tar" effect.
Answer:
Hello!
The answer is A. Analysis of DNA sequences
Explanation:
Classification:
Classification is the assortment or arrangement of living organisms into groups on the basis of their similarities. These groups into which organisms are classified are called taxonomic groups or taxon.
- Before the 1960s, scientists solely relied on phenotypic or physical characteristics of organisms to classify them into related taxonomic groups.
- Modern DNA sequencing methods are capable of revealing similarities and differences between organisms on the level of genes or DNA sequences. Therefore, DNA sequence analysis is the most accurate method for classification.
- Closely related organisms have specific genes with the same DNA sequence. These sequences, known as conserved sequences, can be found universally in all species of a particular organism. For example, in bacteria, a DNA sequence known as the 16s RNA is conserved in related species. 16s RNA analysis is widely used to identify and classify bacteria.
- Behaviors, body structure, habitat and food choices are all phenotypic characters that do not provide definite evidence of evolutionary relationship.
- Different species can have the same habitat, behavior, anatomy and morphology.
