Grace [21]

Answer:

Mitochondria

Explanation:

Pyruvic acid enters the mitochondria where in the presence of oxygen it is converted into acetyl coenzyme A. Acetyl coenzyme A joins the Krebs cycle in which it is broken down to carbon dioxide, water and energy which is used to produce ATP. ATP is a complex organic molecule.

water's unique property of ______ allows water molecules to stick together so they can be pulled upward by the force of transpir
My name is Ann [436]
Cohesion. Cohesion is the property of water that attracts other water molecules so they can stick together. Water is sticky because it has positive and negative charge in the oxygen and hydrogen ends that attracts one water molecule to another. Adhesion is also a property of water that attracts it from other substances, making it easy for water to travel upwards through transpiration.

What is a toxic chemical produced by our excretory system called.
slega [8]

Answer: ammonia

Explanation: Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder

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.

Hormones from final target organs inhibit release of anterior pituitary hormones is an example of which hormonal release
xeze [42]
There are three types of hormonal release control (increase or decrease production), which is stimulated by
1. specific molecules, minerals or particular nutrients ( chemical regulation)
2. other hormones (hormonal regulation)
3. input from nervous system. (neural regulation)

If the inhibition is caused by a different hormone, it would be considered hormonal regulation.  In the given example, the hormone is produced in the target organ.

However, if the inhibition is due to the accumulation of the hormone itself, then it is an example of a <em>negative feedback</em>.
