A:mold and cast fossil
B:index fossil
C:trace fossil
D:petrified fossils
Answer:
B:index fossil
Explanation:
The trilobite fossils are examples of index fossils.
Index fossils are most desirable for stratigraphic construction and to predict ancient life forms on earth.
Index fossils are fossils with the following characteristics;They have short stratigraphic spanThey have a wide geographic distributionShows rapid evolutionary trends or changes.Trilobite is one of such fossils that have the above listed properties.

what is the "Cell (plasma) membrane"? Question 1 options:
the structure that forms the surface of a cell separating its contents from the outside world.
a type of cell without a membrane-bound nucleus and without membrane-bound organelles, considered by scientists to be a more primitive type of cell than the more complex eukaryotic cells.
a small organelle, made of RNA and protein and found in both prokaryotic and eukaryotic cells, that forms proteins from amino acids .
a cell organelle that is essential to cell functions including reproduction, contains the cell's chromosomes, and is enclosed by a membrane.
Answer:
The first option
Explanation:
The cell membrane is the structure that forms the surface of a cell separating it's contents from the outside world.

Explain what the title of this article and video, "The Albatross, Harbinger of Human Migrations" means. In what ways should humans and their governments act like the scientists working with albatrosses
Answer:
Albatross are the indicators for migration of humans.
Explanation:
The Albatross, Harbinger of Human Migrations" means that Albatross are the indicators for migration of humans from that location. Humans and their governments act like the scientists working with albatrosses by making environment suitable for them. The humans have to reduce interventions in the places where they are present in order to increase occur in their population. governments should made policy for them to secure their habitat and prevent them from extension.

Answer:
best for identifying whether a rock is intrusive or extrusive is texture (c)
Explanation:
importance of respiration
Answer:
Respiration is important because it converts food energy into chemical energy.
Explanation:
In vesicular transport, __________ transport materials into and out of the cell using _______.
Endocytosis and exocytosis transport materials into and out of the cell using vesicles.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, which are covered by the formation of a vesicle that detaches into the cell, forming phagocytic vesicles.In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are wrapped in a vesicle towards the Golgi apparatus, where they are released to be used by other cells or by the body in different processes.Therefore, we can conclude that exocytosis and endocytosis are the biological processes responsible for the transport of particles and substances into and out of the cell.

What direction will solutes move if a protein pump is functioning properly?
Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane.
Explanation:
The epithelial cells of the small intestine have large numbers of mitochondria.
Explain how this is an adaptation for the function of these cells.
Answer:
★ - Mitochondria is site of ATP production.
★ - High respiration rate if there are lots of them for active transport.
★ - Needed for the metabolic activity - absorption of digested foods
Explanation:
Hope you have a great day ;-)
Mitochondria is the power house of ATP production, The epithelial cells of the small intestine have large numbers of mitochondria as it is needed for the metabolic activity like absorption of digested foods.
What are the function of mitochondria ?Mitochondria is the power house of the cell which is made up of double membranes responsible for production of energy, contain proteins, lipids, and nucleic acids.
If mitochondria is destroyed, the cell dies and the outer membrane of mitochondria is very similar to the nuclear membranes the nucleus where the inner membrane is bigger and forms multiple folds called cristae.
The area present between two membranes is called the matrix, have circular DNA, multiple proteins and essential molecules, it take of sugars by cellular proteins, enter Krebs cycle produces smaller molecules.
When electron moved a spike of energy is generated called as ATP.
