A trilobite fossils has been used to tell us how life on earth has changed. Trilobite fossils are examples of?
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 would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?
O The water would move out of the cell and the cell would decrease in size.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size
Which will most likely cause a decrease in the predator population? an increase in prey populations 2. a decrease in prey populations 3. a decrease in decomposers 4. an increase in producers.
Answer:
[tex]\huge\boxed{\sf A \ decrease \ in \ prey\ population}[/tex]
Explanation:
Predators are those animals which hunt prey. Prey is the animals which is "hunted".
When the prey population is less (a decrease in prey population), There will not be more animals for "predators" to hunt and so, the competition of living will become more. Decrease in preys population would lead to a decrease in predator's population because many predators will die of hunger.
[tex]\rule[225]{225}{2}[/tex]
Hope this helped!
~AnonymousHelper1807Answer: B a decrease in prey populations
Explanation: Because if there is a decrease in the predator population decreased, then wouldn't the prey.
How is the principle of superposition helpful in determining the age of the earth? Justify your response in two or more complete sentences.
How is stratigraphy helpful in determining the age of the earth? Justify your response in two or more complete sentences.
please hurry and answer both of these questions, this is important and put your answer again in the comments, thank you and please hurry.
Explanation:
The principle of superposition states that "in an undisturbed sequence of strata, the oldest is usually at the bottom and the youngest on top of it".
Judging by this, we know that sedimentary rocks are arranged on top of one another. We can use this to determine relative age because we know for sure the oldest layers are at the base of the sequence and the youngest are on top.
ii. Stratigraphy deals with the relative way in which strata are deposited in sedimentary basins.
It is useful in determining age of rocks because, rocks in different localities can be correlated using stratigraphic principles.
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.
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.

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.

the way a punnet square works is that you basically multiply two genes. for example:
b b
B Bb Bb
b bb bb
then, if it's uppercase, it is dominant. if it's dominant, it will take over the recessive gene. if it was Bo, B being brown and dominant, and o being recessive and orange, then brown would take over. there are also cases with codominant but that's not in the question. feel free to ask me anything about this.
