Scribe

Hey its Jarod here with todays post. When we walked in today a weird butsome what funny video was playing and we had to grab the animal of the day slip. when everyone was settled we were told that the animal of the day was a weird looking animal called a Axolotl. This is also know as the mexican walking fish because it has little feet that it uses to help it swim. Its class is amphibia. It is native to mexico and a cool fact is that it is use in scientific experiments because it can regenerate most of its body parts, a characteristic that we don't have. Once we got past the animal of the day we learned about 6 different invertebrate animal phylums. We talked about Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda and last but not least Echinodermata. I am not going to go in to detail with every thing that we talked about today. Our homework was to read 26.1 and to finish the green chart. During class today you could have actually got a lot of stuff to put on the green chart but you didn't have to. Other homework is to finish the animal profile and do your reading list. The scribe for tomorrow will be.......................Jonathan b. Good luck!

Muddiest Point

Hey its Jarod. My muddiest point is what is adaptive radiation again. I forgot please help.

Muddiest point

The muddiest point for me would have to be the stages of a fertilized egg. I get some of them but not all. If you could give me a little help, please.

Muddiest Point

My muddiest point today is about autosomal dominant. Is it like recessive and all have to be capitals of only one has to be capital. I need help.

Spinal Muscular Atrophy

Spinal muscular Atrophy or (SMA) is a genetic disorder that attacks the survival motor neuron or in other words it attacks the nerves in the spinal cord that helps the person move all their voluntary muscles. SMA is an autosomal recessive genetic disease. In order for the child to get this disease both parents have to have the abnormal gene and pass it on to their child. The likelihood of a child getting SMA is 1 out of 4. The individual with SMA has a missing or a mutated gene (SMN1) that produces the protein called Survival Motor protein. Without SMN the nerve cells may atrophy, shrink and then die leaving muscles weak. The chromosomes that SMA is found on are either the 5, 11, x, and the 20 chromosome.

Signs and symptoms :

• Decreased or absent deep tendon reflexes
• Hypotonia or diminished muscle tone
• twitching of muscles
• Respiratory problems
• Sluggish performance in activities
• aching of limbs

Diagnosis for SMA is usually throw a blood test. In the blood test they look for the presence or absence of the SMN1 gene. There is no treatment for this disease. supportive care is very important to the patient and to check every couple of weeks with your doctor. This disease is not common. Only 1 out of 6000 people will get this disease.No real population is at risk of SMA. only half of all people live to 50 with SMA.

Muddiest point

Help! My muddiest point is the difference between b cells and t cells. I have trouble understanding what they do. Help me.

It's Jarod!

At the start of class we turned in the unit packet pages 13-18. Those pages were about how bacteria grows and how some of the antibiotics we used had killed them in their tracks. That assignment lead us in to a talk on how some bacteria could live in the zone of inhibition(to the right). Even thought you can't see it there are tiny colonies of bacteria that are in that zone right now! These bacteria are resistant to that antibiotic. The way that they can live there is because ether went threw spontaneous mutation or conjugation. Those are some big words. I hope you took notes! After we did the DOD which was Tuberculosis. The agent was bacteria itself and it is highly contagious and it's a huge health concern. Then we did a little lab on how a girl fell of her bike and got infected with bacteria and went to the hospital. They tried many antibiotics on her and she got better. some were able to resist antibiotics A,C,D. I won't tell you the answer myself. All of the above concluded the day.

The next scribe is Mark.

Muddiest point

Hey guys its Jarod. My muddiest point was probably immigration and emigration. I some what got the concept but it was still very confusing. It kind of confused me about the part how they went for food and all that but i could still use so help. That is my muddiest point.

Hello class this is Jarod. Sorry for the so late post but here is your scribe for friday. We started off class with the copying down of homework and taking lab 58 out of our work books. We then corrected our homework from the night before. The homework was about how predators and prey balanced in life(right). We then learned about lab 58. It was about population density. We had to see how many clover, dandelion and plantain plants were in a meter area. We then took 2 meter sticks, some string and a meter square and headed outside. Mrs. Stein pointed to a place that we were to set up and start working. My group consisted of Trenton, Anthony and myself. (pic. of us working is up above). All of us then went back inside and tried to finish the lab so it wouldn't be for homework. Also we copied the classes findings down to complete the table.

Next Scribe is: Anthony

Unit One Reflection

Hi its Jarod. Unit one was exciting. We learned many new things like how to adjust a microscope and how to observe and infer. One of the big labs were the jumping beans. The way they moved was so unrealistic. The labs with the microscopes were cool too. The refresh of how to sight the microscope and how the powers were to be adjusted helped. Over all it was a good unit. Looking forward to the next unit.
