Mrs. Sue, please help
I think the first one is chemical, the second one is urine, the third one is pathogens, the fourth one is antibodies, the fifth one is ligaments, and the sixth one is lungs. Please help Mrs. Sue
I agree with your answers.
I'll be glad to check your answers.
1. Chemical digestion occurs in the small intestine through the action of enzymes.
To get the answer to this question, you can refer to a biology textbook or reliable online sources that explain the process of digestion. The small intestine is an organ in the digestive system, where the majority of chemical digestion and nutrient absorption takes place. Enzymes, such as pancreatic enzymes and brush border enzymes, break down proteins, carbohydrates, and lipids into smaller molecules that can be absorbed by the body.
2. Urea, excess water, and other waste materials are eliminated in a water fluid called urine.
This information can be found in textbooks or online sources that cover the topic of excretion or the urinary system. The kidneys play a crucial role in eliminating waste products from the body. They filter the blood, remove urea (a waste product of protein metabolism), excess water, and other waste materials, which are then excreted as urine.
3. Viruses can cause infections by injecting DNA or RNA into hosts.
To find the answer to this question, you can refer to a microbiology textbook or reliable online sources that discuss the concept of viral infections. Viruses are infectious agents that can cause diseases in animals, plants, and even bacteria. They are unique in that they cannot replicate on their own and rely on host cells to reproduce. Viruses infect host cells by injecting their genetic material, which can be either DNA or RNA, into the host cell. This genetic material takes over the cellular machinery, hijacking the host's resources to replicate and produce more virus particles.
4. The human immune system produces antibodies in response to a vaccine, which later can bind to and destroy a pathogen if it invades.
To obtain the answer to this question, you can refer to immunology textbooks or reputable online sources that cover the topic of vaccines and the immune response. Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to a foreign substance, such as a vaccine or a pathogen. Vaccines contain harmless or weakened forms of a pathogen, or specific proteins from the pathogen, which stimulate an immune response. When the immune system encounters the vaccine, it produces antibodies that recognize and bind to specific components of the pathogen. If the actual pathogen later invades the body, these antibodies can identify and help destroy it, preventing or reducing the severity of the infection.
5. Ligaments are structures that link bone to bone at a joint.
To find the answer to this question, you can refer to anatomy or orthopedic textbooks, or reliable online sources that cover the topic of joints. Ligaments are fibrous connective tissues that connect bones to other bones at a joint. They provide stability and support to the joint, preventing excessive movement and maintaining its proper alignment. Ligaments can be found in various joints of the body, such as the knee, shoulder, ankle, and wrist.
6. In the heart, blood flows from the right atrium to the right ventricle, where it is pumped to the lungs.
This information can be found in anatomy textbooks or reliable online sources that explain the anatomy and physiology of the cardiovascular system. The heart is a muscular organ that pumps blood throughout the body. Blood enters the heart from the body through the superior and inferior vena cava into the right atrium. From the right atrium, blood flows into the right ventricle before being pumped out through the pulmonary artery to the lungs. In the lungs, oxygen is picked up, and carbon dioxide is released as part of the process of respiration.
