ms. sue please help i have the same question @ms. sue
1. Chemical digestion occurs in the small intestine through the action of enzymes.
To get the answer, you can consult a biology textbook or search online for information about the process of digestion. The small intestine is known to play a crucial role in the breakdown of food through chemical digestion, and enzymes are responsible for breaking down large molecules into smaller ones that can be absorbed by the body.
2. Urea, excess water, and other waste materials are eliminated in a watery fluid called urine.
To find the answer, you can refer to a biology or anatomy resource that covers the excretory system. Urine is the liquid waste product excreted by the kidneys. It contains dissolved waste compounds such as urea and excess water, which are eliminated from the body through the urinary system.
3. Viruses can cause infections by injecting DNA or RNA into hosts.
To understand this concept, you can read about viruses and their mode of action. Viruses are tiny infectious agents that can invade host cells. They inject their genetic material, which can be either DNA or RNA, into the host's cells. This genetic material then hijacks the host's cellular machinery, forcing it to produce more viruses and potentially causing infections.
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 get this information, you can study immunology or consult reputable sources on vaccines and the immune system. Antibodies are proteins produced by the immune system in response to the presence of foreign substances, such as pathogens. Vaccines stimulate the immune system to produce specific antibodies, which can recognize and neutralize or eliminate pathogens if encountered in the future. This immune response provides protection against certain diseases.
5. Ligaments are structures that link bone to bone at a joint.
To find this answer, you can refer to an anatomy textbook or search online for information about skeletal structures and joints. Ligaments are strong bands of connective tissue that connect bones to other bones, providing stability and limiting excessive movement at joints. They help maintain the integrity and support of the skeletal system.
6. In the heart, blood flows from the right atrium to the right ventricle, where it is pumped to the pulmonary artery.
To understand the flow of blood in the heart, you can study cardiovascular physiology or consult credible sources on the circulatory system. The right atrium receives deoxygenated blood from the body, which then flows into the right ventricle. From the right ventricle, the blood is pumped into the pulmonary artery, which carries it to the lungs for oxygenation.
