A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytos
Katena32 [7]
Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!

Describe why food needs to be digested from large to small molecules.
LuckyWell [14K]

Answer:

Food must be broken down into nutrients for the body to use for energy, development, and cell repair. Before the blood absorbs and transports nutrients to cells in the body, food and drink must be broken down into smaller nutrient molecules.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.

The half life of Carbon 14 is 5500 years. How many years will pass for a 30 gram sample to reach 3.75 grams
sertanlavr [38]
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years. 
The original mass is 30 g and the new mass is 3.75 g. 
New mass = Original mass × (1/2)^n, where n is the number of half lives; 
3.75 = 30 × (1/2)^n
 1/8 = (1/2)^n
 n = 3 
Thus, the time taken will be; 3 × 5500 = 16500 years.
