<span>The fourth level of cell organization is the
organ level. The organ level is a structure composed of collections of tissues
that perform specific functions in a living organism. Organs that are found in
a human body are the heart, lungs, brain, pancreas, liver, among others. These
organs perform specific functions and work in an interconnected manner for the
human body to function well. When organs work together, they are called organ
systems which are already the fifth level of cell organization.</span>
Answer:
PFK (protein): cytoplasm only (targeting pathway)
Insulin (protein): ER->Golgi->outside cell
Explanation:
Translation can be described as the mechanism by which a protein is produced through a mRNA.
If a particular protein is to function inside the same cell, then it doesn't need to get any modification so that it can travel outside the cell. Such type of proteins are translated on free cytoplasmic ribosomes and are released directly into the cytoplasm to perform their function. For example, PFK protein.
If a protein has to function outside the cell where it is produced, then it has to be modified. Such type or proteins are translated on the rough ER. They are then modified in the Golgi complex and then transported outside the cell to the area where they have to function. For example, insulin.
Aerial roots perform a number of functions unlike the usual functions performed by roots stationed on soils. They help with air exchange, propagation, stability and nourishment. In many cases, aerial roots can be removed without harm to the plant
Answer:
Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.
But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.
Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
Answer:
Which region of the hip bone articulates with the sacrum? Ilium. The ilium is the largest region of this bone. It articulates with the sacrum at the articular surface.
