PLEASE HELP ME I'M BEING TIMED I WILL DOUBLE THE POINT All Hawaiian honeycreeper bird species have similar skeletal and muscle structures. However, each Hawaiian honeycreeper species has a bill specialized for eating certain foods. What would a scientist most likely conclude based on this observation? Artificial selection shaped the bill for eating certain foods. Increased genetic variation resulted in similar skeletal and muscle structure. Changes in each honeycreeper species occurred independently, but resulted in similar traits. Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.

The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.

Explanation:

All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.

It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
