Answer:
Unisexual and bisexual organisms are differentiated based on the reproductive systems they posses. Unisexual organisms have separate sexes male or female. Male and female reproductive systems are present in different individuals hence unisexual organisms produce male or female gametes but never both. Bisexual organisms have both male and female reproductive systems within the same individual. Hence, they are capable of producing both types of gametes. Some flowers are unisexual, and they possess only pistils or stamens. Some flowers are bisexual, and they possess both stamens and pistils together. This is the difference between unisexual and bisexual organisms.
The characteristic of life it represents is homeostasis.
<h3>
What is homeostasis?</h3>
Homeostasis is the body's attempt to maintain a constant internal environment.
One of the major ways the body achieves homeostasis is through excretion, the process of removing wastes and excess water from the body.
Thus, when the snakes excrete waste products produced from the breakdown of food for energy, the characteristic of life it represents is homeostasis.

Atp energizes other molecules in cells by transferring a phosphate groups to those molecules.
<h3>What about phosphate group?</h3>
- A functional group that has an atom of phosphorus linked to four atoms of oxygen (three single bonds and one double bond).
- If there isn't a link between one of these oxygen atoms and another atom, the structure is a phosphate ion.
- Proteins require phosphate groups to be activated in order to carry out specific tasks in cells.
- The process of phosphorylation, which involves the addition of a phosphate group, activates proteins.
- All living things phosphorylate proteins at some point.
- Bone and teeth are formed with the help of phosphate.
- Additionally, phosphorus is a component of a number of essential compounds, such as those that the cell uses for DNA, cell membranes, and energy (deoxyribonucleic acid).
- Phosphorus is a mineral that the body gets from food and excretes in urine and occasionally stooll.
- The part of the DNA double helix that gives the molecule's structure support is known as the phosphate backbone.

<span>The levels of organization of life from the least
complex to most complex are enumerated below:<span>
<span>a.
Organelles - the basic part of a living organism. It refers to the different
structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria,
nucleus)</span>
b. Cells
- building blocks of life that are composed of different molecules responsible
for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues
- combinations of cells that carry out a specific function in an organism.
(Example: Human skin)
d. Organs
- collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ
Systems - composed of interconnected organs that function as a whole. Many
organisms, particularly mamamals, are composed of organ systems. (Ex.
respiratory, circulatory systems)
<span>f. Organisms
– individual entities that specifically make-up a population. (Ex. Each tree in
the forest is an organism, each animal in sea is an organism)</span></span></span>
g. Population – species living within a specific
location. It could be the same or different species that inhabit a place. (Ex. Birds
are species in the forest as well as bears)
h. Community – refers to the total number of
populations that inhabit a specific location. (Ex. All of the trees, insects,
birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that
function together as a group which also includes the non-living parts of the
environment. (Ex. Rain water, nitrogen in the soil)
<span>j. Biosphere – the highest organization of life
that consist of all the collection of ecosystems in the planet. It includes the
land, air, water, even the atmosphere of the planet. </span>
D all of these create a magnetic field. let me know if you want me to explain.
