Stars have a life cycle, just like people: they are born, grow, change over time, and eventually grow old and die. Most stars change in size, color, and class at least once in their lifetime.

Explanation:
A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.
Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.

<u>Answer:</u> The total pressure inside the container is 77.9 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the total pressure inside the container, we use the law given by Dalton, which is:
![P_T=p_{N_2}+p_{O_2}+p_{Ar}](https://tex.z-dn.net/?f=P_T%3Dp_%7BN_2%7D%2Bp_%7BO_2%7D%2Bp_%7BAr%7D)
We are given:
Vapor pressure of oxygen gas,
= 40.9 kPa
Vapor pressure of nitrogen gas,
= 23.3 kPa
Vapor pressure of argon,
= 13.7 kPa
Putting values in above equation, we get:
![p_T=23.3+40.9+13.7\\\\p_{T}=77.9kPa](https://tex.z-dn.net/?f=p_T%3D23.3%2B40.9%2B13.7%5C%5C%5C%5Cp_%7BT%7D%3D77.9kPa)
Hence, the total pressure inside the container is 77.9 kPa
