What is a material that will be permanently distorted called?
unelastic
The process by which modern organisms have descended from ancient organisms is called?
The process by which modern organisms have descended from ancient organisms is called evolution.
Scientist who study the ocean floor are called?
Benthos
Organisms that must obtain nutrients and energy by eating other organisms are?
All animals are heterotrophs, getting their organic molecules (food, growth) from another organism. Those that consume other organisms are predators. The larger predatory animals that consume smaller animals are carnivores (meat eaters).
What is the bouncing of light off a surface called?
The bouncing of light off a surface is called reflection. When a light wave is bent it is called refraction.
What are the photosynthetic organisms found near the surface of the ocean called?
Phytoplankton
What is attached to surfaces of rough endoplasmic reticulum?
Many ribosomes are attached to the surface of the rough endoplasmic reticulum. That is why it is called " rough. "
What are the small photosynthetic organisms found near the surface of the ocean called?
Phytoplankton
What are organisms that float near the surface of freshwater lakes and ponds called?
plankton
How is the upper surface of fornix is attached to the undersurface of corpus callosum?
by a membrane called septum pellucidum
What are organisms that spend their entire adult lives attached to one spot called?
immobile animal/plant
What does the electrical terminology of the word - fixture - mean?
"Fixture" generally refers to things permanently attached to the structure. A light fixture would be one example, screwed to the wall or ceiling. The light fixture, also called a luminaire, would include devices for holding the lighting elements, supplying electricity to them, enclosing the connections for safety, and means for attaching it to the electrical supply permanently. A "fixture" could, in theory, dangle from a cord permanently attached to a suitable support. For contrast, a cord-connected device would not be a fixture. In fact, it is often illegal to use cord and plug on any appliance that is permanently attached (e.g., screwed in or with water pipes attached).
What are tiny organisms that float near the surface of freshwater and marine envioments called?
the answer is phytoplankton or plankton
What is the soil name in tundra?
Tundra is marked by a permanently frozen layer of soil called permafrost, which can be at considerable depth or just below the surface.
What abiotic factors do organisms that live in the benthic zone need to adapt to?
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos, e.g. the benthic invertebrate community, including crustaceans and polychaetes.[1] The organisms generally live in close relationship with the substrate bottom and many are permanently attached to the bottom. The superficial layer of the soil lining the given body of water, the benthic boundary layer, is an integral part of the benthic zone, as it greatly influences the biological activity which takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud.
What organelle is attached to rough endoplasmic reticulum?
Ribosomes are attached to rough endoplasmic reticulum.
How can you tell rough ER and smooth ER?
The Rough ER has a surface covered by mitochondria - which appear as small circles, and make the surface "rough" in appearance. The Smooth ER does not have these ribosomes, and so the surface is just one smooth line.
