Answer:
Option (1)
Explanation:
Meiosis is also known as reduction division. Meiosis is the process of cell division by which a parent cell divides to give four daughter cells each with half number of chromosomes.
Crossing over may occur during meiosis I of the cell cycle. Crossing over will not occur in the cells immediately after the fertilization of egg and zygote restores the original number of chromosomes.
Thus, the correct answer is option (1).
Answer:
i think yes in 3 4 5 not in 1 2. It's asking if the genetic situation applies to the hardy equillibrium.
Explanation:
Yes it does fit the definition

Answer:
Humans switch from aerobic respiration to anaerobic respiration when they lack oxygen to breathe.
Explanation:
- When humans and other animals lack sufficient oxygen, they'll create ATP through a form of anaerobic respiration.
- Anaerobic means respiration under low oxygen level.
- When you are doing heavy work your heart beats faster to deliver you oxygen. if this oxygen is not enough even at the highest heart beat then your body switches to anaerobic respiration.
- In anaerobic respiration you take glucose and break it down into carbon molecule called as lactic acid.
