A more carbon dioxide leaving the land and moving into the atmosphere as lands are converted into farms and cities
Explanation:
Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome).
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.
Answer:
![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
Explanation:
Total force = Force due to gravity + Force due to charges
Total force = ![\frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGMm%7D%7Br%5E%7B2%7D%20%7D%20%2B%20%5Cfrac%7BkQq%7D%7Br%5E%7B2%7D%20%7D)
r is the separation between particles.
Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs
Mass of a proton (M)= 1.67×10^-27 kilograms
Mass of an electron (m) =9.11 × 10^-31 kilograms
G=6.67 ×10^−11 N⋅m^2/kg^2
k=8.99 * 10 ^9 N.m^2 / C^2
Plugging in values:
Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2
Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2
We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.
Total force = Force due to charges.
F = 2.3 *10^-28 / r^2
r = ![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
You were right, the answer to this is C.
Answer:
A.) food digestion. Smooth muscle and striated muscle are able to contract.
Explanation:
Unlike striated muscle, smooth muscle contracts slowly and automatically. Musculature of internal organs and the digestive system consists of smooth muscles. Therefore, they are involved in food digestion.
