The cell membrane helps to transport ions, nutrients, and waste.
Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The most common method is to use a balance.
- Balances and Scales.
- Space Linear Acceleration Mass
- Measurement Device
- Measurement Transducer
- Vibrating Tube Mass Sensor
- Gravitational Interaction
<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>
Answer:
The world’s largest tropical rainforests are in Amazon basin in South America, lowland regions in Africa, and the islands off of Southeast Asia.
