Answer:
A. Hold and receive food
D Break the food
2. A mouth
3. B compaction
4. C interphase
5. A histone
6. A G0
Explanation:
The main function of the digestive system is to receive, hold and break down the food. Mouth is the place where the digestion of the food starts in the body. Compaction is the process which is not present in the digestive process. Interphase is the longest part of the cell cycle in which cell grows and make copies of its DNA before starting mitosis. Histone is the protein where the DNA coils around to form a chromatin. Cells that mature leave the cell cycle and are arrested at phase is G0 phase.

Answer:
1 / 10 ; 1 / 5 ; 5 / 12 ; 2 / 5
Explanation:
Experimental probability is defined as the ratio of the total number of times an event occur to the total number of trials.
In the experiment performed, the total number of trials is the number of times a paper was drawn from the lot, which 120 times.
From the experiment, the following observations were recorded :
X ___ number of times drawn
1 ____ 12
2 ____18
3 ____ 13
4 ____ 9
5 ____8
6 ____ 24
7 ____ 9
8 ___ 12
9 ___ 8
10 ___ 7
Experimental probability = number of times an event occur / total number of trials
Experimental probability of :
P(1) = 12 / 120 = 1 / 10
P(6) = 24 /120 = 1 / 5
P(an odd) = p(1) + p(3) + p(5) + p(7) + p(9)
P(odd) = (12 + 13 + 8 + 9 + 8) / 120 = 50 / 120 = 5 / 12
A prime number = P(2) + p(3) + p(5) + p(7)
P(prime number) = (18 + 13 + 8 + 9) / 120 = 48 / 120 = 2 / 5
