Explanation:
Answer: D. It yields chromosomes that contain both maternal and paternal DNA.
Explanation:
The recombination or crossing over is a genetic process. It takes place during the Prophase I of meiosis. The homologous pair align and held together by synapsis. This results in the mixture of genes combination formed from both parents that can be represented as a single chromosome.
If the recombination do not occur then each chromosome will be either 100% maternal or paternal. Thus recombination assures the recombinant chromosomes which consists of genetic material from both parents. Thus the genetic diversity of offspring increases.
Answer:
A.Both of you pull with equal force on opposite sides of the ball.
Explanation:
Balanced forces means that the total force or the sum of the force done on the object should be equal to 0 newtons or in other words, it should not be moving.
Force is defined as the push or pull on an object. For both people to balance out the forces on the ball while both applying a force, you need to do this from opposite sides.
You could either pull with equal forces on opposite sides of the ball or you can push with equal forces on opposite sides of the ball.
→ ball ←
← ball →
For the other choices, if you both push or pull on the same side, the ball would move that direction because there is no opposing force.
ball → →
If one pushes while the other pulls on opposite sides, it will move the direction you are pulling and pushing.
→ ball →
I agree with the other answer
