Answer:
The number of hydrogen bonds involved will be 39
Explanation:
There are 4 types of bases that exist in a DNA, which are adenine, thymine, guanine and cytosine. Double stranded DNA molecules have these bases attaching specifically to one another; adenine only binds to thymine and vice versa while guanine only binds to cytosine and vice versa. These two bases bonding together are referred to as base pairs and the type of bond here is the hydrogen bond. There are double bonds between the adenine and thymine base pair while there are triple bonds between the guanine and cytosine base pairs.
Thus, when there are 13 cytosine bases in a DNA molecule, the number of hydrogen bonds present in the resulting base pairs will be 13 × 3 (because cytosine binds with a triple bond to guanine).
13 × 3 = 39
The number of hydrogen bonds involved will be 39
So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.
In DNA, base pairing occurs between complementary nitrogenous bases. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Each base pair is connected by hydrogen bonds.
In a DNA molecule of 50 base pairs with 15 cytosine (C) bases, you can determine the number of hydrogen bonds involved in base pairing as follows:
1. Each adenine (A) pairs with thymine (T) and forms two hydrogen bonds.
2. Each cytosine (C) pairs with guanine (G) and forms three hydrogen bonds.
So, for the 15 cytosine (C) bases, you would have 15 pairs of C-G base pairs, and for the remaining 35 bases, you would have 35 pairs of A-T base pairs.
Total hydrogen bonds involved in base pairing:
(15 pairs of C-G base pairs * 3 hydrogen bonds per pair) + (35 pairs of A-T base pairs * 2 hydrogen bonds per pair)
= (15 * 3) + (35 * 2)
= 45 + 70
= 115 hydrogen bonds.
So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

People who respect critical thinking make up a critical society, and a critical need is anything that is urgent or necessary.
Critical sociology aims to deconstruct old social power structures through analyzing texts, artworks, and other forms of media.
This is distinct from other sociological approaches, which frequently emphasize description over criticism.
Social workers must be able to assess each situation impartially by gathering data through observations, interviews, and research.
Social workers can make educated judgments, find the greatest resources, and create the best plans to assist clients by thinking critically and without bias.
Promoting critical thinking is crucial, and doing so through the eyes of cognitive science paints a clearer picture of what proponents for critical thinking are actually attempting to advance.
Therefore, a critical need of society is one that is urgent or necessary.

Answer:
Urgent
Explanation:
A critical need is one that is urgent or necessary.
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only onevariable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

Answer:
Explanation:
Disconformities and nonconformities are both types of unconformities. Nonconformities occur where layers of sedimentary rock are deposited over eroded igneous or metamorphic rock. Disconformities occur when there is a gap due to erosion or non-deposition between layers of sedimentary rock.
