What is a cell?
-A cell is the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
What is the difference between an animal and a plant cell?
-An animal cell does not have a cell wall but a plant cell does.
-An animal cell is round and a plant cell is rectangular.
Describe the cell functions:
-Muscle- Produce force and motion.
-Nerve-Transmits messages from one part of the body to another.
-Blood- Transports red and white blood cells throughout the body.
Relationships between tissues that make up an organ and the function of the organ
-Cells are the basic structure of life which make up tissues in which make up organs then make up organ systems which help carry out life's basic tasks.
Components and functions:
Digestive system: Your digestive system is uniquely constructed to perform its specialized function of turning food into the energy you need to survive. This consists of the mouth, esophagus, anus, stomach, small intestine, pancreas, liver, gallbladder, large intestine and the rectum.
Circulatory system: The circulatory system is made up of vessels and muscles that help control the flow of blood around the body. This consists of the head, arms, lungs, liver, stomach, kidneys and legs.
Respiratory system: A system of organs functioning in respiration. This consists of nasal passage, oral cavity, pharynx, larynx, trachea, bronchi, lungs, heart and ribs.
-It looks like a cell, but it functions on its own like it is a single organism.
2- 75% green flowers and 25% yellow flowers
3- A pure dominant green flower and a pure dominant yellow flower.
4- Two heterozygous, Gg
5- Asexual reproduction is a form of reproduction in which an organism creates a genetically-similar or identical copy of itself.
-Adaptation- The action or process of adapting or being adapted.
-Evolution- The process by which different kinds of living organisms are thought to have developed from earlier forms during the history of the Earth.
-Species- A group of living organisms consisting of similar individuals capable of exchanging genes ro inbreeding.
-Gene- a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
-Genetic-of or relating to genes or heredity.
-Sexual reproduction- the production of new living organisms by combining genetic information from two individuals of different types.
-Asexual reproduction-A mode of reproduction by which offspring arise from a single organism.
-Partly determine organsims' physical form and function. Helps organsims cope with current environmental variability. Reduces potentially deleterious effects of breeding among close relatives. Primary basis for adaptation to future environmental uncertainty.
Sexual and Asexual Reproduction:
-Terrestrial ecosystem- Can be found anywhere apart from heavy saturated places.
-Forest ecosystem- Has an abundance of flora, or plants, is seen so they have a been number of organisms which live in a relitively small space.
-Aquatic ecosystems- An ecosystem found in a body of water.
-Freshwater ecosystem-. Covers only 0.8% of Earth's surface and contains 0.009% of the total water.
-Grassland ecosystem- Mainly comprises grass with a little number of trees and shrubs.
-Decomposer-an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
-Consumer-a person or thing that eats or uses something.
-Ecosystem-a biological community of interacting organisms and their physical environment.
-Producer-An autotrophic organism that serves as a source of food for other organisms in a food chain.
-Food chain-a series of organisms each dependent on the next as a source of food.
-Biotic-of, relating to, or resulting from living things, especially in their ecological relations.
-Abiotic- physical rather than biological; not derived from living organisms
-Adaptation- the action or process of adapting or being adapted.
-Decomposer- some types of decomposers are Bacteria and Fungi. Others are worms, and mushrooms. The worms live in the ground. They eat their way through bits of dead plants and animals.
-Consumer-Consumers include deer, wolves, bears, grasshoppers, hawks, etc.
-Ecosystem-There are tropical rainforest, Grassland, Desert etc. Ecosystems.
-Producer- Trees are one example of a producer.
-Food chain- butterfly - small birds - fox
-Biotic- Autotrophs, heterotrophs, and detritivores.
-Abiotic-These may be plants, animals, fungi, and any other living things
-Adaptation- Countless species engage in group living, either in herds, colonies, harems, complex societies or loose associations.
Biotic and Abiotic factors in a wetland ecosystem:
Wetland food chain ecosystem:
12.Energy enters the ecosystem through light from the sun.
13.The arrows represent the energy flow through each organism.
14. If an element were to be eliminated from the food chain then the ecosystem would die or the organisms would adapt through natural selection.
15. Wetlands filtrates the water by retaininf excess nutrients and pollutions.
16. Wetlands reduce floods because they trap and slowly release surface water, snow, rain, and flood water.
17. Wetlands plants hold the soil in place with their roots, absorb the energy of waves, and break up the flow of stream or river currents.
18. Animals that live in the wetlands for food, shelter, and breeding grounds.
19. The wetlands prouce natural products, has historical, scientific, and cultural values.
Energy flow through an ecosystem:
How lifestyle choices effect the human body...
There are many different decisions that you need to make in life. It is always important to make the right decision for you. For example, in the article "The Doctor Will See You Now" it talks about how your genes are modified by the choices we make everyday. So if we decide to eat not healthy foods, then the result will be unhealthy. Another example of how your decisions influence your life is by if you smoke, not only is smoking bad for the person doing it but it is also a risk for the people that are around you when you are smoking. In the Secondhand Smoke article it states, "Since 1964, approximately 2,500,000 nonsmokers have had breathing problems or have even died from health problems due to exposure to secondhand smoke." So even though you are the one who is smoking, it still effects others as well. According to the article "Cigarette smoking and air quality", it states that air pollution emitted by cigarettes is 10 times greater than diesel car exhaust. So this means that by smoking, it lets off more pollution into the air than a car does, and cars are used all over the world all of the time. Also if you don't make good decisions on what you eat than that is going to make you in greater risk for not being healthy in the future and that is not a good way to live. So in conclusion, decisions that you make determine your destiny, therefore is you choose to eat junk food or smoke, or make any other bad decisions for you then you will not have a very promising future for you or the people around you. But on the flip side, if you make good decisions than that will make you live a much more accomplished lifestyle, so always try to make good decisions for yourself and others around you.
