How does genetic drift affect small populations differently than large populations?

1 answer:

dalvyx [7]2 years ago

7 0

Answer/ Explanation:

In small populations, the relative effect of genetic drift is higher because deleterious alleles can become more frequent by chance, and less common alleles have a greater chance of being permanently lost. This reduces the genetic variation in the population.

Large populations are less likely to change quickly as a result of genetic drift, this is due to chance

What happens to the pressure of a gas inside a container if the temperature of the gas decreases?

My name is Ann [436]

Answer:

Pressure Increases

Explanation:

When the temperature of a gas is increased inside a container then the pressure of the gas inside the container increases.

This can be deduced by the Ideal Gas law equation:

$P.V=n.R.T$

where:

P = pressure of the gas

V = volume of the gas

n = no. of moles of gas

R = universal gas constant

$T=$ temperature of the gas

So,

$P\propto T$ hence the pressure of the gas will increase while the temperature is increased at a constant volume

At a point 1.2 m out from the hinge, 14.0 N force is exerted at an angle of 27 degrees to the moment arm in a plane which is per

geniusboy [140]

Answer:

$\tau = 7.63 Nm$

Explanation:

As we know that moment of force is given as

$\tau = \vec r \times \vec F$

now we have

$\vec r = 1.2 m$

$\vec F = 14 N$

now from above formula we have

$\tau = r F sin\theta$

here we know that

$\theta = 27 degree$

so we have

$\tau = (1.2)(14) sin27$

$\tau = 7.63 Nm$

A falcon can descend with a speed 250 km/h. If a falcon flies at this speed for 2.0 s and then flies a 100 m in 2.5 s, what is t

Vadim26 [7]

Answer:

v= s/t

Explanation:

250 km/ h =69.44m/s

S1=2 times 69.44 ≈ 139m

Next 2.5 seconds:

S2 = 100m

Average speed:

v=139m+100m/2s+2.5s = 239/4.5s = 53.2 m/s=192km/h

Light of wavelength 476.1 nm falls on two slits spaced 0.29 mm apart. What is the required distance from the slits to the screen

stich3 [128]

Answer:

The distance is $D = 2.6 \ m$

Explanation:

From the question we are told that

The wavelength of the light is $\lambda = 476.1 \ nm = 476.1 *10^{-9} \ m$

The distance between the slit is $d = 0.29 \ mm = 0.29 *10^{-3} \ m$

The between the first and second dark fringes is $y = 4.2 \ mm = 4.2 *10^{-3} \ m$

Generally fringe width is mathematically represented as

$y = \frac{\lambda * D }{d}$

Where D is the distance of the slit to the screen

Hence

$D = \frac{y * d}{\lambda }$

substituting values

$D = \frac{ 4.2 *10^{-3} * 0.29 *10^{-3}}{ 476.1 *10^{-9} }$

$D = 2.6 \ m$
