How does the respiratory system help build social relationships? The respiratory system helps create sound that enables humans to communicate with each another. The respiratory system helps prevent the spread of disease so humans are able to live in communities together. The respiratory system helps humans have feelings and base decisions on those feelings. The respiratory system helps humans remember and recall memories of friends and special times.

In biology class one day, Mrs. Chabon wrote six physiological functions on the board. Then, she asked groups of students to each choose the three functions that are purposes of the excretory system. These are the lists they made. Group 1: maintaining pH level of blood; transporting hormones throughout the body; regulating growth Group 2: removing wastes from the body; digesting solid foods; maintaining salt and water balance Group 3: maintaining salt and water balance; maintaining pH level of blood; regulating growth Group 4: removing wastes from the body; maintaining pH level of blood; maintaining salt and water balance Which group correctly listed the functions of the excretory system? group 1 group 2 group 3 group 4

Which of the following has the smallest number of cells? blastocyst zygote fetus embryo

The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food does not get into the lungs? The salivary glands secrete enzymes that pull food out of the air pathway. The small intestine pushes the air out of the digestive system. The pancreas breaks down food in the air pathway. The epiglottis closes the air pathway so that food will not enter it.

How does the structure of the alveoli allow for its function of gas exchange? Alveolar sacs produce mucus that makes gas exchange easier. Alveolar sacs rely on valves to ensure that air flows only in one direction. Alveolar sacs are located within muscles that contract, which increases gas exchange. Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.

A team from New York Presbyterian hospital is conducting a study about a recent increase in cases involving both excess sweating and kidney stones. What would the team need before it draws a conclusion about the cases? medications that are specifically designed to treat the sickness machines that are built to process blood and reduce symptoms until patients are healthy again data that profile the various patients who report these symptoms proof that the excess sweating is related to the excessive kidney stones

What do structures B and C have in common? http://media.edgenuity.com/evresources/3209-12-02/mc008-1.jpg Both contain chyme. Both contain partially digested food. Both contain waste material ready for removal. Both contain stored food.

Which terms best complete the chart about characteristics of human development between fertilization and birth? Stages of Human Gestation First trimester Second trimester Third trimester - Embryo develops - Organs begin to develop - (1) - Starts swallowing - Fat begins to develop - (2) - All organs are developed - Can hear and see - (3) (1) Facial features form (2) Heartbeat can be heard (3) Nerve cells develop rapidly (1) Heartbeat can be heard (2) Nerve cells develop rapidly (3) Facial features form (1) Nerve cells develop rapidly (2) Facial features form (3) Heartbeat can be heard (1) Facial features form (2) Nerve cells develop rapidly (3) Heartbeat can be heard

During a third-trimester ultrasound, what would a doctor expect to observe in a fetus? initial development of organs response to noise and light presence of a tail-like structure the first heartbeat

What do the pancreas, liver, salivary glands, and gall bladder have in common? They are all involved in mechanical digestion. They are all accessory structures. They all digest carbohydrates. They all release digesting enzymes.

A sudden change in the body's salt and water balance would most likely be caused by a malfunction in which organ? liver kidney bladder lungs

A disorder causes a human offspring to have 47 chromosomes instead of 46. In which process was there most likely a malfunction? birth blastocyst formation fetus development gametogenesis

Homeostasis is the ability of the body to maintain internal balance despite changing external conditions. How does the respiratory system help maintain homeostasis? The respiratory system helps release hormones to control body processes. The respiratory system helps release unwanted heat and water from the body. The respiratory system produces white blood cells that kill disease-causing organisms. The respiratory system releases enzymes that help in the break down of food.

Which of the following starts to break down as soon as they enter the mouth? carbohydrates proteins fats nucleic acids

Asthma is a respiratory disorder that causes constriction of the airways. This constriction may cause difficulty in breathing. If a doctor were asked to create a medication, what would the medication most likely do? redirect airflow around inflammation increase diffusion of oxygen kill foreign pathogens decrease inflammation of blocked airways

In which of the following scenarios does skin help to maintain body temperature? When jumping into cold water, one's skin releases body heat into the water. While walking during a hot summer day, one's skin releases sweat that contains heat. After accidentally touching a hot cookie sheet, a blister forms on one's finger where all the heat entered the body. After a long run, an Olympic athlete stretches out her arms and legs.

Which diagram correctly displays the order of events during egg formation? primary oocyte ® secondary oocyte ® meiosis I ® meiosis II ® ovum ovum ® meiosis I ® primary oocyte ® meiosis II ® secondary oocyte primary oocyte ® meiosis I ® secondary oocyte ® meiosis II ® ovum primary oocyte ® meiosis I ® ovum ® meiosis II ® secondary oocyte

What is one difference between a primary oocyte and a secondary oocyte in humans? A primary oocyte contains 46 chromosomes, while a secondary oocyte contains 23 chromosomes. A primary oocyte is produced after birth, while a secondary oocyte is produced before birth. A primary oocyte develops in both men and women, while a secondary oocyte develops only in women. A primary oocyte is the product of meiosis, while a secondary oocyte is the product of mitosis.

The excretory system helps the respiratory system by introducing more oxygen into the lungs. circulating blood into and out of the lungs. removing carbon dioxide that is produced during respiration. removing urine that is produced during respiration.

What percentage of water is lost through the respiratory system? 5 to 10 percent 10 to 20 percent 35 to 50 percent 50 to 75 percent

Drinking alcohol during pregnancy negatively impacts development of the fetus because: the mother's body is unable to process alcohol. alcohol crosses the barrier that the placenta creates. the mother can no longer produce primary oocytes. alcohol causes the mother to have facial distortions.

Which correctly lists all the structures that secrete lipase? pancreas and stomach pancreas, salivary glands, and stomach pancreas and salivary glands pancreas, salivary glands, and liver

A medical biologist is examining one of many cells that are produced during the human oogenesis process. The cell is haploid, meaning that it has 23 chromosomes, and it was removed from the body shortly after it entered the fallopian tube. The cell had begun the process of meiosis II, but did not finish it. What type of cell is the biologist most likely examining? a fertilized egg a polar body a primary oocyte a secondary oocyte

Which process produces human egg and sperm cells? fertilization ovulation pregnancy gametogenesis
