Both, actually. They both add up to 46 chromosomes. If you have less than 46, you will come out with Autism. Hope this helps!
Answer:
Solution
For figure (a)
During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.
During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.
During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.
For figure (b),
During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.
During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.
During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived
They have two pairs of main nerve cords organized around a number of paired ganglia. while they don't have a "true brain"-- they have somewhat of a nervous system, composed of the two, or three pairs of nerve cords contained in the visceral mass.
This is kinda a weird question for me to answer... BUT.... lol
I think it is Meiosis, which occurs over two cycles of cell division, which sperm cells complete before fertilization. It also is the process that creates gametes -- sperm and egg cells -- containing only one, or a haploid, set of chromosomes.
And fertilization is the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote... OR
it could be the action or process of applying a fertilizer to soil or land.
Hope this helps. c;
Hearing gives an animal advantages such as being able to listen out for predators, so the animal can run away. The hearing can aid the animal when hunting for other animals, because it can stay still and wait for the right timing to attack, etc.
