Scientists use squid nerve cells in research because the nerve cells of a squid are 1,000 times fatter than those of a human. how is the outcome of nerve cell research most likely to be affected if scientists were to study human nerve cells directly? a) the outcome would be different because humans and squids are very different. b) the outcome would be different because the nerve cells in squids are much larger than those of humans. c) the outcome would be the same because in both cases a nerve cell is being researched. d) the outcome would be the same because genes in squids and humans are 85 percent ide

B.The outcome would be different because the nerve cells in squids are much larger than those of humans.

The most appropriate answer would be option C.

The outcome would be almost the same as the nerve cell is being researched in both cases.

The properties of a nerve cell, the way they propagate nerve impulse, the function they perform in the body et cetera would remain the same in both humans as well as squid.

The squid nerve is preferred due to its width as it allows the scientist to perform experiments more precisely and conveniently.

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#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.
