One of the important developments in human evolution is Bipedal locomotion

Answer: C. Bipedal locomotion

Explanation:

One of the important evolution of humans is the bipedal locomotion. According to the evolutionary relationships, humans are the descendants of chimpanzees. The chimpanzees have quadrupedal locomotion in which they locomote with the help of two hands and two feet.

Humans have evolved and locomote with the help of only two legs and the hands are free to do any work. The evolution occurred due to the changes in gene in the entire population of humans.

What evidence is there that the o’higgins glacier is being affected by global warming?

Leno4ka [110]

The distinct evidence of climate change in the O’Higgins glacier is proven by the measurement of the area that it covers. About 11.5 kilometers of glacier land has melted within the twentieth century. Satellite images reveal the retreat of glaciers where they compared early 1900s images from the present.

Which is the safest area for towing a skier? near the shoreline where others can watch near other skiers or swimmers in the wate

Elan Coil [88]

The answer would be in the middle of the lake away from other skiers or swimmers in the water.

Given the choices that would be the best answer because it is the safest. When towing a skier, you need to be at a safe distance from hazards like the shoreline, swimmers, boats, and skiers. It is advisable that you distance yourselves at least twice the length of the rope you will use for towing.

Boats are able to stay afloat because of the force caused by...

Ugo [173]

Answer:

d) buoyancy

Explanation:

Buoyancy can be defined as an upward force which is created by the water displaced by an object.

According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.

Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.

The buoyancy of an object is given by the formula;

$Fb = pgV$

$But, \; V = Ah$

$Hence, \; Fb = pgAh$

Where;

Fb = buoyant force of a liquid acting on an object.

g = acceleration due to gravity.

p = density of the liquid.

v = volume of the liquid displaced.

h = height of liquid (water) displaced by an object.

A = surface area of the floating object.

The unit of measurement for buoyancy is Newton (N).

Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.

Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.
