how do structures in an organisms relate to their functions
Answer:
The relationship of a structure and function is the structuring levels from molecules to organism ensure successful functioning in all living organism and living system.
Explanation:
Function and structure are related, because of a certain structure a living thing make contain makes the object function the way it does. There is a lot of structural future in humans, plants, animal and all living things.
What is located on chromosomes
Answer:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells.
Explanation:
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Identify the nitrogenous base NOT present in RNA.
Adenine
O Thymine
O Guanine
Cytosine
Answer:
Thymine
Explanation:
Uracil is the nitrogenous base present only in RNA, but not in DNA. ... DNA have thymine, guanine, adenine and cytosine. Thymine is replaced by uracil in RNA.
which do all cells need in order to function?
a: oxygen
b: water
c: carbon dioxide
d: offspring
Answer:
A. Oxygen ( for animals )
B and C ( for plants )
Explanation:
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.
In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.
Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
What are Cells?Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.
Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.
Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.
This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.
Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.

Spartina is a group of grasses that dominates communities of salt marshes in many coastal areas. Many of the insects, snails, birds, mice, and other animals found in these communities rely on Spartina for food, nest building materials, protection for their young, etc. The roots of Spartina also form dense mats that hold together soil in these ecosystems. Many species that live in Spartina salt marshes cannot survive outside of these unique ecosystems. Because living near the ocean is desirable to many humans, many Spartina marshes have been drained & cleared for human development. Analysis of the destruction that came when Hurricane Katrina hit Louisiana in 2005, however, showed that the reduction of salt marshes in coastal Louisiana was a contributing factor to the storm surge penetrating further inland.
1. The value of Spartina salt marshes in protecting coastal areas from storm surge would be classified as which type?
A. Extrinsic.
B. Intrinsic.
C. Neither.
2. The value of Spartina salt marshes in holding soil together would be classified as which type?
A. Extrinsic.
B. Intrinsic.
C. Neither.
3. In general, you would expect species that only live in Spartina salt marshes to have a higher extinction risk than species that can survive in urban areas.
A. True
B. False
4. Based only on the information included in this scenario, extinction risk for species that only live in Spartina salt marshes would be most influenced by which factor?
A. Restricted geographic range.
B. Narrow habitat requirements.
C. Small population size.
Answer:
1)a. Extrinsic
2) b. Intrinsic
3) a. True
4) a. Restricted geographic range
Explanation:
1. Spartina Salt marshes are important to the coastal areas as they protect them from storm surge as affecting the erosion of salt marsh edges and it is classified as extrinsic.
2) b. Intrinsic
Intrinsic factors such as vegetation and soil affect the erosion of salt marsh edges. It is determined by characteristics of soil and root biomass found under the ground.
3) a. True
Species that could survive in urban areas are less prone to extinction than the species that only survive in spartina salt marshes.
4) a. Restricted geographic range
A restricted geographic range is a factor that leads and affects the extinction in endemic species more.
