Meiosis creates the gamete cells, because these cells are used in reproduction they only have 26 chromosomes two of these cells join together to make a full 46 chromosomes.
Hope this helps! :)
(a) 
The work-energy theorem states that the work done on the cheetah is equal to its change in kinetic energy:

where
m = 51.0 kg is the mass of the cheetah
u = 0 is the initial speed of the cheetah (zero because it starts from rest)
u = 31.7 m/s is the final speed
Substituting, we find

(b) 6.1 cal
The conversion between calories and Joules is
1 cal = 4186 J
Here the energy the cheetah needs is

Therefore we can set up a simple proportion

to find the equivalent energy in calories:

Answer:
continually change by the same amount each second
Explanation:
We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.
Since the basic units are meter and seconds. And the SI unit of velocity is
and acceleration's SI unit is 
For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is
and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is
.
False. When a chemical reaction occurs, atoms don't create or destroy. They are rearranged as bonds and are broken and formed together.
Answer:
Ondas y sonido. Una onda es una perturbación que avanza o que se propaga en un medio material o incluso en el vacío. ... El sonido es un tipo de onda mecánica que se propaga únicamente en presencia de un medio material.
