Answer:
The correct option is cell wall and central vacuole.
Explanation:
The cell wall can be described as an additional membrane around the cell membrane which is present in the plant cells but is absent in animal cells.

Answer:
The correct answer would be - remain the same.
Explanation:
In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:
weight daily intake
132 2250
154 2450
176 2650
198 2850
220 3050
242 3250
In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.
Thus, the total calories he takes: 2700
burn by exercise: 295
should take: 2450
then = 2700 - (2450+295)
= 50 calories over the limit that will have negligible effect on the weight.
One reasonable plan would be to wear a face mask or surgical
mask. Take note that your surgical mask contains two sides – the white side and the
blue side. Since the main purpose of your mask usage is to prevent yourself
from inhaling too much bad air, the blue side of the mask should be the one
touching your skin. This is because the white side of your mask helps you
prevent from coming in contact with toxins that may come from the smog.
