PLEASE HELP MY DAUGHTER WANTS ME TO CHECK HER HOMEWORK AND I DON'T KNOW TO MUCH ABOUT SCIENCE LOL! BUT PLEASE HELP PLEASE PLEASE HELP ME PLEASE 'IN YOUR OWN WORDS PLEASE' PLEASE PLEASE PLEASE 'IN YOUR OWN WORDS' IN YOUR OWN WORDS PLEASE' I'M BEGAN YOU PLEASE PLEASE ANYBODY HELP......!!!! :( :( : ( : ( :( !!!! ???? I'M THE PARENT NO LINKS IN YOUR OWN WORDS PLEASE PLEASE !!!!! NO LINKS NO LINKS
THANK YOU ...
1) Describe the relationship between your skeletal muscles and your bones.
2) Describe how homeostasis is maintained in the body using the negative-feedback system. Provide an example.
3) Explain what a reflex action is. Why do reflex actions help animals to survive? Use an example to explain how a reflex action works.
4) Describe the fertilization process and explain why only one sperm fertilizes each egg.
5) Describe what happens to body systems over time from infancy to adulthood to older adulthood.
Why is there such big words?
I am in school and I hve learned about that lesson about all that already. I found it in my book. It was easy. You just have to take the time and read it! As a matter of fact I got a 98% of the homework. & I had only 1 person help me on one question. I agree with Ms. Sue, use your own words! Just telling you, reading the book would be easier than just scattering around for answers because it isn't going to make your child learn anything if you beg for answers.
1.Bones are considered to be part of your skeletal system
3. A reflex cant be controlled
5. Body systems become weaker with time and less immunse to diseases
Of course, I'd be happy to help explain these concepts to you! Here are the answers to your daughter's homework questions:
1) The relationship between skeletal muscles and bones is a close one. Skeletal muscles, which are connected to bones through tendons, are responsible for moving our bones. When muscles contract and relax, they create movement at our joints, allowing us to perform various activities such as walking, running, or lifting objects. Simply put, our skeletal muscles work together with our bones to enable our body to move.
2) Homeostasis refers to the body's ability to maintain a stable and balanced internal environment. This is achieved through a negative-feedback system. In this system, when a certain variable deviates from its set point, the body initiates a series of responses to bring it back to the normal range. An example of this is the regulation of body temperature. When we get too hot, our body activates cooling mechanisms such as sweating to lower our temperature. Conversely, when we get too cold, our body triggers warming mechanisms like shivering to raise our temperature. The negative-feedback system helps to keep our body's internal conditions within the optimal range.
3) Reflex actions are automatic and rapid responses of our nervous system to a specific stimulus. They occur without conscious thought, allowing for quick reactions to potentially dangerous situations. For instance, when you accidentally touch a hot stove, your reflex action causes you to pull your hand away immediately, even before you consciously perceive the pain. Reflex actions enhance survival because they help protect our body from harm and prevent further injury. They allow us to react swiftly without having to go through the slower process of consciously analyzing and initiating a response.
4) The fertilization process occurs when a sperm cell combines with an egg cell to form a fertilized egg or zygote. During sexual reproduction, millions of sperm are released during ejaculation into the female reproductive system. However, only one sperm successfully penetrates and fertilizes the egg. This is because the outer layer of the egg, called the zona pellucida, undergoes changes after the first sperm penetrates it. These changes prevent any additional sperm from entering. This ensures that only one sperm cell contributes its genetic material to form an embryo, avoiding the possibility of multiple fathers for the same offspring.
5) As our body progresses from infancy to adulthood and older adulthood, our body systems go through various changes. In infancy, many systems are still developing, and growth is rapid. The bones continue to grow and harden, muscles become stronger, and the immune system develops. During adulthood, the body systems reach their peak efficiency and functionality. However, as we age into older adulthood, some changes occur. Muscles may begin to lose strength and mass, bone density can decrease, and the cardiovascular system may become less efficient. The immune system might weaken, making us more susceptible to infections. These changes vary from person to person and can be influenced by genetics, lifestyle, and overall health.
I hope these explanations help! If you have any further questions, feel free to ask.
