What is the role of deoxyribonucleic acid (DNA) in organisms?
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

Infer If the rock layers shown above hare
not been disturbed, what type of dating
method would help you determine which
layer is oldest? Explain.
Answer:
radiometric dating methods
Explanation:
The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.
anyone help please!!!

How does a bird develop?
Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
Answer:
Explanation:
Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.
The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.
The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

What is Natural Selection? Give an example for Natural Selection for Survival.
Answer:
is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds
Explanation:
It's sorta like adapting with extra steps.
Answer: Natural Selection
Explanation: Individuals in a species have variation or mutations.
These differences may either be helpful, such as a giraffe with a long neck, or unhelpful, such as a colour variance in a moth that makes them stand out to predators.
The individuals that are more suited to their environment will survive and breed, passing on their genes.
Those that are not suited will die and their genes will not be in the ‘gene pool’.
This is the survival of the fittest!

define magnification and cisternae?
Answer:
Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.
Explanation:
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.
How could you determine the identity of a bacterium?
Answer:
THE RELATIONSHIP OF IDENTIFICATION TO BACTERIAL CLASSIFICATION AND NOMENCLATURE. In order to identify an unknown bacterial isolate, the characteristics of the isolate must be compared to known taxa. In microbiology, the basic taxonomic unit is the species, and groups of related species are placed in the same genus.

B) A longer neck to reach the vegetation that is high up in the trees.
C) A better digestive system for breaking down plant material.
D) Larger ears and eyes located on sides of head to detect predators.
Answer:
B

Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

If I wanted to prepare to run a marathon, what type of macromolecule would I want
to consume?
Answer:
Complex Carbohydrates
Explanation:
There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.
