What can possibly kill sperm in the Great Sperm Race?
Lynna [10]

Answer:

Answer:

THE GREAT SPERM RACE:

A sperm's race to fertilize an egg is not so easy. Out of about 250 million sperm ejaculated into the human vagina during intercourse, not more than one in a hundred will survive the Great race to the end due to the hurdles it has to face in the hostile, ACIDIC CHAMBER to the cervix (it has hundreds of tiny branching tunnels that can trap, crush and slowly kill sperm).

How many food calories can a human burn up in an hour by exercising at this rate? (remember that only 20.0 % of the food energy
blsea [12.9K]

Human can produce a maximum mechanical power of 1/3 hp (horse-power).

Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)


So:

1 ph = 746 watt = 746 J/s

1/3 ph = 248.6 J/s

we're looking for the calories, so

1 joule = 0.239006 calories


So human produce a maximum mechanical power of:

248.6 J/s = 82.88 calories per second.


We're looking for the number of calories consumed in three hours, so:

82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).


The number of food calories is 895.2 food calories

People claim these rock formations in the Sahara Desert look like a mushroom and a chicken. They were not sculpted by humans. Wh
miskamm [114]
Mainly because of erosion by the wind, which geographers call abrasion. When the wind blows in some hot deserts it will pick up millions of grains of sand. When the wind hits an outcrop of rock the sand it is carrying is blasted against it. Over time it would form to become that funky mushroom shape.
hope this helped! :))
