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.

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.
What might happen to a cell if its cell membrane fails to function properly?
Answer:
If cell membrane fails to function then the cell will not be able to perform its task properly. The organelles will stop working which means no more protein created, no more energy production in the mitochondria and no material comes in and out of the cell. Eventually the cell will die.
Your welcome
Answer:
If the cell membrane is unable to do its job properly, this can cause the cell to stop working properly. If many cells have bad cell membranes, the disease can affect an entire organ or even the whole body. In many of these cell membrane diseases, proteins within the cell membrane don't transport materials properly.

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

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.

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.

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.

NEED HELP ASAPP!!!! 1. Which of these is smaller: a cell or a protein?
Answer:
[tex]\boxed {\boxed {\sf Proteins}}[/tex]
Explanation:
Proteins are found inside the cell. There are proteins in the cell membrane and cytoskeleton, they act as enzymes inside the cell, and they are created inside the cell during protein synthesis at the ribosome.
Since proteins are part of the cell and are made inside the cell, the proteins must be smaller.
The size comparison between a cell and a protein depends on the specific cell and protein being considered. In general, cells are larger than proteins.
1. Cells: Cells are the basic building blocks of life and can vary in size depending on the organism and cell type. For example, a human red blood cell has a diameter of about 7-8 micrometers, while a typical animal cell can range from 10 to 30 micrometers in diameter.
2. Proteins: Proteins are biomolecules made up of amino acids and have a variety of functions in cells. Proteins can vary in size, with some being relatively small and others much larger. For example, insulin is a small protein consisting of two polypeptide chains, each about 21 amino acids long. In contrast, titin is the largest known protein and can contain over 38,000 amino acids.
Therefore, while cells are generally larger than proteins, it is important to consider specific examples to accurately compare their sizes.
