Question 1.) part a.
before starting the lab make your best prediction for the outcome of the finches with the scenario’s data.
data—environment with equal amounts of insects, seeds, and fruit. write your prediction here.
question 2.) data—environment with equal amounts of insects, seeds, and no fruit. write your prediction here.
question 3.) post-lab reflection.

The finches are a type of birds that have lot of variations among them, or rather high speciation. The speciation has been the result of the free niches in the food chains and their adaptations to exploit a particular type of food source. Some finches feed on insects, some on fruits, some on seeds, and that has contributed to different types of beaks among them so that they can be more efficient when it comes to obtaining food. If there are equal amounts of insects, seeds, and fruits in a particular environment, than the numbers of finches that feed upon them will also be roughly the same if there isn't any changes in their food sources. The finches that feed upon the fruits and seeds though will be in higher numbers than the finches that feed upon insects, and the primary reason for this is that the plants are producers, thus they provide more energy, while the insects are consumers, so they provide less energy.

It can be stated that the finches, their numbers, and amount of species, directly depend on the environment and the food sources available in it. As this is a highly adaptable type of bird that often is able to out-compete the other species feeding on the food sources, if there is the slightest gap in the food chain, it will occupy it. The more food sources there are, the larger the population of the finches, and the more different types of food sources there are, the higher the speciation among the finches. The population size though will directly be dependent on the type of food source and the amount of energy it provides for the birds.

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.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
