Give an example of a mutation and explain how it could affect an organism?<br> Your answer

ella [17]

Answer:

A mutation is a heritable change in the genetic material of an individual. The change can be large or small. Large changes involve the loss, addition, duplication, or rearrangement of whole chromosomes or chromosome segments. Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

A super slow snail can travel 2.2cm in one minute. How far (in pm) can it travel in 24 hours? Please round to appropriate number

Cloud [144]

Answer : The distance covered by slow snail in 24 hours is $3.2\times 10^{13}pm$

Explanation :

As we are given that the a slow snail can travel 2.2 cm in 1 minute. Now we have to calculate the distance covered by slow snail in 24 hours.

First we have to convert 24 hours in minutes.

Conversion used : (1 hour = 60 minutes)

As, 1 hour = 60 minutes

So, 24 hour = 24 × 60 minutes

= 1440 minutes

Now we have to calculate the distance covered by slow snail in 24 hours.

In 1 minute, the distance covered by slow snail = 2.2 cm

In 1440 minute, the distance covered by slow snail = 1440 × 2.2 cm

= 3168 cm

= $3.2\times 10^3cm$

Now we have to convert 'cm' into 'pm'.

Conversion used : $1cm=10^{10}pm$

As, $1cm=10^{10}pm$

So, $3.2\times 10^3cm=\frac{3.2\times 10^3cm}{1cm}\times 10^{10}pm=3.2\times 10^{13}pm$

Therefore, the distance covered by slow snail in 24 hours is $3.2\times 10^{13}pm$
