Compare and contrast sexual and asexual reporduction

makvit [3.9K]

Difference:

The biological process of sexual reproduction requires the input of genetic material from many people. When a flower self-pollinates, for example, the term "individual" might refer to gamete cells developing as a single physical or even genetic organism. I don't want to substitute the word "cell" for "person," either, as that would eliminate instances of acellular biologic entities that reproduce, like viruses. When a piece of a chromosome from one bacterium is injected into another, it recombines and reproduces there, with or without sporulation, which is one instance of what I consider sexual reproduction but which not all viewers would. My notion just requires some genetic material, even in the form of an episome, not gametes. Asexual phases are included in nearly all forms of reproduction, but I regard all of them to be a part of sexual reproduction when they take place throughout a life cycle that also contains an obligatory sexual phase. Brewer's yeast serves as an illustration of the distinction I make because either the diploid or haploid stage, which could be classified as a gametophyte or sporophyte, can be maintained through an infinite number of mitoses. As a result, I consider vegetative propagation to be asexual reproduction.

Now that you have the difference compare the similarties.

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.
