I’m pretty sure it’s either A or C. Please help???
I was hoping there are some personal trainers who could offer me a bit of advice?
In a couple of months I’m going to start a home study program to prepare for my personal trainer certification. I’m doing it so I can work part-time as a personal trainer to help me pay for school
(I haven’t decided who I’ll do it through. NCSF? ACE? Any suggestions?).
I’m waiting a couple of months to make sure I’m not only physically ready, but also that I have enough knowledge that the study program and exam should be a breeze.
What I want to know is, what types of things should I be studying on my own time to prepare? Nutrition? Skeletal/muscle systems? Types of exercises with no weights, free weights, ball, resistance band, machines etc..
I’m not sure what else would be good things to learn. Any advice would be wonderful!
please answer these questions if you can. 
thank you

C. 2 nanometers
D. 1 meter long
2. a cells plasma membrane would not contain:
A. phospholipid
B. nucleic acid
C. protein
D cholesterol
E. glycolipid
3. Which of the following would you expect to find in or on cells whose main function is absorption?
A. microvilli
B. cilia
C. Desmosomes
D. Gap junctions
E. Secretory vesicles
4. adult cell types expected to have gap junctions include
A. skeletal muscle
B. bone
C. heart muscle
D. smooth muscle
5. for diffusion to occur, there must be
A. a selective permeable membrane
B. equal amounts of solute
C. a concentration difference
D. some sort of carrier system
E. all of these
Thank you so much..
I refused to dissect a frog, so I’ve been given the worksheets to find the answers on the internet.
Sadly, I’m having a hard time finding the answers. So if someone could give me a website that has information on frog anatomy, that would be great, or help answer some questions.
1.Why dissect the nerves last?
2. Describe the frog’s respiratory system
3. Location and structure of the heart?
4. Location and function of frog’s skeletal muscles.
Anything will help. Thanks a bunch.
i need to know what systems of the body (nervous, skeletal, muscular systems) are in volved in Rosacea…if u dont no wat this disease is leave this quesitno alone… i also need to know what organs/glands are involved in the disease…

Quick and Ruben’s breakthrough was in recognizing that this “knee running” anatomy, where the upper leg bones are fixed, is crucial in keeping birds’ lungs from collapsing. Thus, if birds walked like us, they would not be able to support the sophisticated pulmonary system that helps enable flight.
“This is fundamental to bird physiology,” Quick explained. “It’s really strange that no one realized this before. The position of the thigh bone and muscles in birds is critical to their lung function, which in turn is what gives them enough lung capacity for flight.”
In the next phase of research, the scientists examined whether theropod dinosaurs’ skeletons would have allowed a similar pulmonary system. But the evidence shows that skeletal differences—including a mobile femur—meant dinosaurs couldn’t have given rise to birds. “Theropod dinosaurs had a moving femur and therefore could not have had a lung that worked like that in birds. Their abdominal air sac, if they had one, would have collapsed. That undercuts a critical piece of supporting evidence for the dinosaur-bird link,” Ruben said.
Intriguingly, Ruben commented on the widely held dinosaur-to-bird-evolution model: “Frankly, there’s a lot of museum politics involved in this, a lot of careers committed to a particular point of view even if new scientific evidence raises questions.” A startling reminder—especially since it comes from an evolutionist—of how presuppositions play a role in determining science

Hey.
I have some questions about my science homework. Here they are:
What is the maintenance of a stable internal enviroment?
What are 2 or more tissues working together?
What is the soft, flexible tissue that changes to bone?
What tissue covers and protects other tissue?
What is a group of cells working together?
What tissue contracts and relaxes to produce movement?
What tissue send electrical signals throughout the body?
What tissue joins, supports, protects, insulates, nourishes and cushions organs?
What muscle contracts to move bones?
What kind of bone has many open spaces and contains marrow?
What tissue attaches skeletal muscle to bones?
What kind of bone does not have open spaces?
What system is made up of muscles and connective tissue that attaches them to bones?
What bones protect your spinal cord?
What kind of joint allows you to flex and extend your lower leg?
If you can provide answers to any of these questions that would be amazing! Thanks!
