Renal medulla
The renal medulla contains the renal pyramids, where urine formation takes place. Urine passes from the renal pyramids into the renal pelvis. This funnel-shaped structure occupies the central cavity of each kidney and then narrows as it extends out to join the ureter.
Among the following scientists (Michael Faraday, Albert Einstein, Gregor Mendel, and Charles Darwin), the one who is known for developing the laws of heredity is C) Gregor Mendel.
<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>
Because of the 7 billion people that live on this earth :)
