How did the asteroid that smashed into Yucatan, Mexico 66 million years ago kill so many organisms (including the non-avian dino
Bad White [126]

Explanation:

Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 66 million years a couple of things can happen:

Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.

The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.

Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.

taurus [48]

Answer:

of the low pH of the vagina.

Explanation:

The pH of the vagina is maintained at highly acidic levels to prevent the germ buildup. The range of vaginal pH is around 3.8 to 4.5. The very low pH of the vagina creates a hostile environment for sperms and most of the sperms are killed as they enter the vagina due to the acidic pH.

Apart from supplementing the sperms with energy, cervical mucus serves to protect the sperms from the hostile conditions of the vagina. The cervical mucus has an alkaline pH at or near the ovulation to protect sperms from acidic pH of the vagina and to facilitate fertilization.
