The article is about how Barry Bonds getting on steriods. I think he was jealous of McGwire, because he was playing good ball and it was getting to Bonds. Bonds starting making remarks to people saying that McGwire was using juice which is another away of saying steriod. So then Barry Bonds started using steriod hisself to hit more homeruns and get bigger. His personal trainer Anderson provided him with the drugs. The steriods started having their side effects and caused Bonds to blow out his left elbow and he had spent seven weeks on the disabled list. Soon he pulled a groin muscle and was sidelined again.
My response to steriods are bad, because of the way Barry Bonds used them. He is an competitive person, he acts as if he don't want no one that played baseball when he did to get all the attention. He was jealous of McGwire when he was getting all the attention. He shouldnt have let nothing like that get the best of him. He should have already knew someone better than him was going to step in any day. People that use steroids the way Bonds did, dont have no respect for their self treating their body the way they do. They only time someone should use steriods is when the doctor has gave them a presciption for it. Other than that, i think it is bad!!

Skeletal Muscle Physiology Worksheet
1) What percent of the body is smooth muscle? 5% to 10% Striated muscle? 40%
2) Name 3 types of muscle proteins. What is the function of each? Stroma protein constitutes about 1/5 of the muscle protein. It funtions solely as an inert structional element or skeleton, to hold the rest of the structures in place. Cellular protein also comprise about 1/5 of the muscle protein. Contractile proteins: myosin and actin, are essential for contraction.
3) What is a myofibril? consist of smaller myofilaments which form regular repeating pattern along the lenght of the fibril.
4) Sketch a picture of a sarcomere. Label the I-band, the A-band, the Z-line and the H-zone. (above)
5) Name the two filaments that make up a sarcomere. Thick filaments and This filaments
6) Draw a sarcomere at rest, stretched out and contracted. (above)
7) What is the sliding filament theory? the thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere
8) Muscle relaxation ensues upon the removal of what? calcium ions

Integumentary Study Questions in Text
Critical Thinking Questions (3,6, and 8)
3. As a rule, a superficial partial-thickness burn is more painful than one involving deeper tissues. How would you explain this observation? deeper burns, you dnt have no type feeling.
6. How would you explain to an athlete the importance of keeping the body hydrated when excercising in warm weather? Drink enough water while you are in the heat so you wont get hydrated from the hot air while you are doing your excercisings!!
8. How is skin peeling after a severe sunburn protective? How might a fever be protective? It allows your new cells to restore your skin.
Review Exercises:(4,5,6,8,13,15,16,22,25,27,28, and 29)
4. List six functions of skin excretion, heat regulation, control of evapotation, protection, absorption and sensation.
5. Distinguish between the epidermis and the dermis. g. epidermis: outer layer, thin, and divide into 2 layers. AND dermis: region of connective tissue, under epidermis and contain collagenous and elastic resilient.
6. Decribe the subcutaneous layer. under the dermis; fatty layer
8. List the layers of the epidermis. stratum lucidum, corneum, granulosum, spinosum, and germinativeum
13. Distinguish between a hair and a hair follicle. hair is outgrowth of proteins and hair follicles are the skin that grows the hair by packing cells together.
15. Describe how nails are formed. nails are made of a protein called keratin that is produced from living skin cells in the fingers and toes.
16. Explain the function of sebaceous glands. they act to protect and waterproof hair and skin, and keep them from becoming dry, brittle and cracked.
22.Describe the body's responses to decresing body temperture. the nervous system signals dermal blood vessels to constrict and sweat glands to remain inactive, then the body heat is conserved and it rises back to normal.
25. Describe three physiological factors that affect skin color.
27. Distinguish among first-, second-, and third-degree burns.
28. Describe possible treatments for a third-degree burn. require medical treatment
29. List three effects of aging on skin. appearance, temperature regulation, and vitamin D

Cell-ebrity Squared Video
There are 5 basic life functions
Growth and Development
Respond to Environment
Nutrition
Reproduce
Respond to environment
All living things have certain things in common
Adaptation to their environment
Growth
Circulation
Sensitive to environment
Reproduction
Cells
The building blocks of life are cells.
All cells in a human are not the same. Please give examples of at least two different types of cells in humans. 1.
Why are cells not the same? b/c they reflect the different functions they serve.
The first person to discover cells was Rober Hooke. He called them cells because they looked like monks' cells called cellula. He first saw cells when he was looking at a piece of cork under a microscope.
The cell theory was created by Theodor Schwann and Matthias Jakob Schleiden.
The three main ideas in the cell theory are
Cells are the basic unit of life
All organisms are made up of one or more cells
All cells arise from pre-existing cells
Unlike animal cells, plant cells contain the organelles _choroplast_ and _______________________________.
All animal cells are covered in a cell __ membranes__. The function of this is to maintains integrity of the cell, controls the passage of materials into and out of the cell, and provides for signal transduction.
The different parts of the cell are known as __organelles__. Each organelle has a specific function. The function of the nucleus is enclosed by a double-layered, porous membrane and contains DNA; the dense core of an atom that is composed of pretons and neutrons. The mitochondria are also known as the ___________________________ of the cell because their function is to release energy from food molecules and transform energy into unable form. Storage is the main function of the _vacuole_.
Bacteria are interesting organisms. Bacterial cells do not have a _membrane_. Instead the chromosomes of the cell are located _necleoid_.
There are different types of transport used in cells as well. _Diffusion_ is the movement of particles from high concentration to low concentration. Osmosis is different than this because it requires _semi-permeable membrane __ and _solute_.
What is the difference between active and passive transport? active transport are cellular energy and passive transport are molecular
What organelle makes the energy used in active transport? osmosis
Is a virus a living cell? no
What is contained inside a virus? RNA and DNA
What is the only life function of a virus? reproduce
