Humans reproduce by cell division.
True
False

False

Explanation:

Single-celled organisms use cell division as their method of reproduction. Humans are not single celled, we are multicellular, therefore this conclusion is incorrect.

Hope this helps :)

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
