Answer:

creates the necessary male and female gametes

creates gametes with one set of chromosomes

Explanation:

Meiosis is a type of cell division employed by sexually-reproducing organisms. It produces four genetically different daughter cells that have their chromosome number reduced by half i.e. from diploid (2n) to haploid (n). Meiosis is the process whereby organisms produce their necessary gametes needed for sexual reproduction.

Male organism produces haploid male gametes(n) while female organisms produce haploid female gametes (n). These gametes contain one set of chromosome (haploid) because they have to unite in a process called FERTILIZATION. When they do, they form a diloid zygote (2n), which has the same number of chromosomes as each parent cell. That is n+n= 2n.

How do I find the speed of sound when given Frequency and displacement?
IceJOKER [234]

Answer: Taking into account sound is a wave, we can use the information of the displacement (generally given as a graph) to find the wavelength and frequency, then we can calculate the speed with the formula of the speed of a wave.

Explanation:

If we have the displacement graph of the sound wave, we can find its amplitude, its wavelength and period (which is the inverse of frequency).

Now, if we additionally have the frequency as data, we can use the equation of the speed of a wave:

s=\lambda f

Where:

s is the speed of the sound wave

\lambda is the wavelength

f is the frequency

An electric wall clock has a second hand 15 cm long. at the tip of his hand, what is the magnitude of the velocity?
Mila [183]

The velocity of the tip of the second hand is 0.0158 m/s

Explanation:

First of all, we need to calculate the angular velocity of the second hand.

We know that the second hand completes one full circle in

T = 60 seconds

Therefore, its angular velocity is:

\omega = \frac{2\pi}{T}=\frac{2\pi}{(60)}=0.105 rad/s

Now we can calculate the velocity of a point on the tip of the hand by using the formula

v=\omega r

where

\omega=0.105 rad/s is the angular velocity

r = 15 cm = 0.15 m is the radius of the circle (the distance of the point from the centre of rotation)

Substituting,

v=(0.105)(0.15)=0.0158 m/s
