How many atoms are in a 70 kg human?
topjm [15]

Answer:

7 followed by 27 zeros

Explanation:

The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.

The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.

In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.

iogann1982 [59]

Answer:

The correct answer is option d) "head-on".

Explanation:

In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man
IgorLugansk [536]

Answer:

Number of nucleosomes in 2.9 * 10^9bp is equal to 1.47 * 10^7

Explanation:

For wounding one nucleosome, total length of DNA required is equal to 146 bp

The length of  linker DNA in mammals is equal to 50 bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

= 146 + 50\\= 196bp

Thus, in 196bp length of DNA, the total number of nucleosomes is equal to 1

Thus, number of nucleosomes in 2.9 * 10^9bp is equal to

\frac{2.9* 10^9}{196} \\1.47 * 10^7
