External fertilization
In this type of fertilization, the female lays numerous eggs and they are fertilized externally by the males that ‘pours’ its sperm on the eggs.
Explanation:
While laying of many eggs gives an increased chance of diversity in the population, many offspring don't make it to maturity due to low parent care. There is, therefore, more wastage of reproductive energy compared to internal fertilization.
On the other hand, in internal fertilization, the egg is fertilized inside of the female and develops into a young organism before it is birthed. Even though there are fewer offspring produced, the more parental care they receive gives them an increased chance of survival. There is also low reproductive energy loss.

The part of the brain stem that regulates vital activities such as heartbeat,breathing and digestion is the<u> Medulla oblongata. </u>The bottom part of brain which regulate your breathing,heart rhythms,blood pressure and swallowing.
The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing.It's locate where the brain and spiral cord connect, it help in control vital processes like our heartbeat, breathing and blood pressure.
This also responsible for reflexes of the face and throat like - coughing,sneezing,gagging. It can lead to respiratory failure, loss of sensation, paralysis,it causes 'brain death" and person can not survive.

Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
