Explanation:
DNA can be used to tell people apart because humans differ from each other based on either their DNA sequences or the lengths of repeated regions of DNA. The technique of gel electrophoresis separates DNA by size, thus allowing people to be identified based on analyzing the lengths of their DNA.
Total number of different committees = C(14,6) = N
We have two cases where we have less than 2 teachers.
case 1: 1 teacher (out of 5)
Number of ways to choose 1 teacher = C(5,1) = 5
Number of ways to choose the remaining members from students = C(9,5)
Total number of ways to choose a committee with exactly 1 teacher = 5C(9,5) = N1
case 2: no teacher
Number of ways to choose 6 students = C(9,6) = N2
Probability to choose at least two teachers
= (N-N1-N2)/N
=109/143

Explanation:
Barriers and gatekeepers are both functions of cell membranes. They're semi-permeable, which means some molecules can pass through but others can't. The concentration of particular chemicals inside the cell is controlled by specialised proteins in the cell membrane.
A cell's plasma membrane, also known as the cell membrane, offers protection. It also maintains a constant environment within the cell, and the membrane serves a variety of purposes. The first is to carry nutrients into the cell, and the second is to transport harmful chemicals out.
