A ___________ mutation occurs when a base in the DNA sequence is replaced by a different base.

77julia77 [94]

Answer:

Missense Mutation

Explanation:

The types if mutations include: Missense mutation. This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. An insertion changes the number of DNA bases in a gene by adding a piece of DNA.

Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruis

White raven [17]

Answer:

23.38 years

Explanation:

Speed of Allison = 0.83 c = v

Time passed according to Allison = Δt = 29.5 years

Time dilation

$\Delta t'=\frac{\Delta t}{\sqrt{1-\frac{v^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-\frac{0.83^2c^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-0.83^2}}\\\Rightarrow \Delta t'=52.88\ years$

For Nora 52.88 years would have passed

So, their age difference would be 52.88-29.5 = 23.38 years

A mass of 3.6 kg oscillate on a horizontal spring with a spring constant of 160 N/m.

Darya [45]

Answer:

48.7 J

Explanation:

For a mass-spring system, there is a continuous conversion of energy between elastic potential energy and kinetic energy.

In particular:

- The elastic potential energy is maximum when the system is at its maximum displacement

- The kinetic energy is maximum when the system passes through the equilibrium position

Therefore, the maximum kinetic energy of the system is given by:

$KE=\frac{1}{2}mv^2$

where

m is the mass

v is the speed at equilibrium position

In this problem:

m = 3.6 kg

v = 5.2 m/s

Therefore, the maximum kinetic energy is:

$KE=\frac{1}{2}(3.6)(5.2)^2=48.7 J$

The elastic energy stored in your tendons can contribute up to 35%% of your energy needs when running. Sports scientists find th

zzz [600]

Answer:

11.16 J

Explanation:

Elastic energy (E) stored in the tendon is given by 1/2ke^2

SPRINTERS

k = 31N/mm = 31N/mm × 1000mm/1m = 31,000N/m

e = 41mm = 41mm × 1m/1000mm = 0.041m

E = 1/2 × 31,000 × 0.041^2 = 26.06J

NON-ATHLETES

k = 31,000N/m

e = 31mm = 31mm × 1m/1000 = 0.031m

E = 1/2 × 31,000 × 0.031^2 = 14.90 J

Difference = 26.06 J - 14.90 J = 11.16 J
