Ways the HIV virus causes a syndrome of the immune system is by an infection with human immunodeficiency virus which makes a person experience an influenza-like illness. A syndrome is a ton of symptoms that occur all at once. HIV and other dangerous diseases can possibly destroy the human body because the immune system can only protect the body from bad cells and also pathogens. HIV is a dangerous disease that can be given to people by unprotected sex. Having like a stuffy nose, sore throat, or a headache does not bother people very much but if you have HIV which then moves on to AIDS, it scares people because it is a serious disease that you can't defend yourself from. AIDS is what comes after HIV which kills people by causing symptoms.
There is a ratio between the size of the organisms heartbeat and the organism in all mammals. Every mammals heart beats either faster or slower than others. In the human body, the heart beats at least around 70 times per minute but a squirrels heartbeat would be faster and beat at least around 200 times per minute. This signifies that the smaller a mammal is, the faster their hearts beat, but a much larger mammal would have less beats per minute. Every animal has a certain amount of heart beats throughout its life. The less heartbeats an animal has, the longer it lives, but the most heartbeats an animal has each minute wouldn't not have a very long life.
In this 3-class lesson i have learned about certain muscles in a chickens wing and in a cat. We had a lab that had to do with dissecting a chickens wing and learned about muscles in it. A couple muscles we learned about
were the forearm muscle, biceps, humerus, ligament, and more. Another activity we did is, we drew the body of any mammal we chose with out its skin (just of the muscles in the body) and had to give a description of each muscle in the body. Some muscles that are in a cat are the infraspinatus muscle, the deltoid muscle, the sartoris muscle, and the bicep femoris muscle. The average age for a pro football player would be 25 years old because that's around the time all the bones in a human body have developed. When they are finished being developed they are big strong bones for mostly healthy people. You can sprint faster and its easier to tackle someone when your 25 with these developed bones than tackling someone when you're 35. The average age for an ultra marathon runner would be 35 years old mostly because a person ages and when people start aging, their bones get weaker. Being an ultra marathon runner is not as crazy and rough as football so you wouldn't need to use a lot of your muscles like you would in football.
