The scientific method of making observations is how information is obtained through the senses. A person can see, touch, smell and hear things in order to make an educated guess to how things will end up panning out for whatever scientific things they are researching.

Answer from: EstherAbuwaah

Making observations is the step of scientific method in which information is obtained through the senses.

Making an observation is the first step of scientific method where scientists gets curious about a natural occurrence or a phenomenon.

Further Explanation. Scientific method involves a process where researchers or scientists search for answers to certain questions and solutions to problems. Scientific methods are used by scientists or researchers to test a given hypothesis. Steps involved in Scientific method Making an observation and asking question. Making observation is the first step of any scientific process. The scientists make observations about a natural phenomenon.After making observations scientist asks a question about an observed phenomenon or pattern. Observations may be qualitative where the occurrences are described in ways that do not use numbers or quantitative where observations contain numbers and other features. Formulating a hypothesis Hypothesis refers to probable answers to the question asked and one that can be tested experimentally. Hypothesis is therefore a possible explanation for a given observation or occurrence. For the observation that we experience alternating periods of light and darkness that correspond to the movement of the sun, moon, and clouds. The hypothesis here would be; The earth rotates on its axis for 24 hours, thus, exposing one side to the sun or else the sun revolves around the earth for twenty four hours. Designing and performing experiments Suitable experiments be carried out to test the validity of the hypothesis formulated. Experiments refers to organised measurements or observations normally made under controlled environment. Accept or modify the Hypothesis The experiment conducted helps the researchers or scientists to determine whether the hypothesis formulated is valid. If the hypothesis is valid then they proceed to the next step of scientific method. However, if the experiments demonstrate that the hypothesis is incorrect then it must be corrected for further experimentation. Developing a law and/or a theory After conducting experiments and analyzing the results obtained, the researchers may test whether the results are reproducible and hence a law may formulated to allow general prediction. A scientific law describes a phenomenon or pattern, it describes what happens but does not explain why.

Answer from: Quest

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.

Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. which of the following best describes a challenge in classifying organisms this way? a. there are millions of species on earth, and a cladogram is not a practical means for classifying all of them. b. it is impossible to tell which organisms are most closely related to each other using a cladogram. c. cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. d. there is a limited number of ways to organize the information, so most cladograms end up looking very similar.
