Which is not a function of the respiratory system? *
It warms air entering the body.
O It exchanges oxygen and carbon dioxide.
O It pumps blood to the organs.
O It creates sound through the voice box.
Answer:
it exchanges oxygen and carbon dioxide
Explanation:
You inhale oxygen and exhale carbon dioxide
Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.
The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.
It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.
The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.
The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.
Thus, the option 3 is not the function of the respiratory system.

Explanation:
A 56-year-old man with an insufficient aortic valve is scheduled for surgery. Identify the chamber of the heart that the regurgitated blood most likely enter. Will the blood regurgitated primarily during systole or diastole?
Answerand Explanation:
The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.
As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.

Mass wasting is movement of rock and soil down the hill. The rocky hillside slopes can be secured by slope reinforcement. if the slopes are not stabilized, landslide can cause damage.
What do you mean by mass wasting?Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity.
The most common types of mass wasting are slumps, rockslides, debris flows, and earthflow. Slumps are slow and short-distance downslope movements of semi-consolidated earth material on a curved or planar sliding surface.
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil.

The brain and spinal cord are part of the central nervous system.
The electrical charges that act as nervous signals are called action potentials or nerve impulses.
Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.
After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.
Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.
Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.
Muscles move endo- and exoskeletons by contracting and relaxing.
Fertilization is the joining of two gametes called sperm and egg.
A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.
Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.
Describe three different strategies used by three different animals to thermoregulate.
Elephants: Elephants thermoregulate by using their large ears as cooling devices. They flap their ears to increase surface area and enhance heat loss through evaporative cooling.Desert Lizards: Desert lizards employ behavioral thermoregulation by basking in the sun to absorb heat and warming their bodies. They also retreat to shade or burrows to avoid excessive heat when needed.Penguins: Penguins have a unique thermoregulation strategy. They huddle together in large groups to conserve body heat and shield themselves from the cold Antarctic winds, effectively reducing heat loss and maintaining body temperature.If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?
If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.
Answer:
1. central
2. action potential
3. nerve net
4. dorsal
5. hydrostatic
6. Exoskeletons
7. contraction/contracting
8. Fertilization
9. external fertilization
10. Eggs
11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.
12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)

Mobile receptors mechanism
Mobile receptors play a crucial role in the transmission of signals between cells and are essential for various physiological processes in the human body. These receptors are proteins that are embedded in the cell membrane and are specifically designed to bind with specific molecules, such as hormones, neurotransmitters, and other signaling molecules. The mechanism of mobile receptors involves several steps that allow for the efficient and accurate transmission of signals.
1: Binding: The mobile receptor recognizes and binds to its specific ligand, which is the signaling molecule. This binding occurs through complementary shapes and chemical interactions between the receptor and the ligand.
2: Activation: Once the ligand binds to the mobile receptor, it induces a conformational change in the receptor's structure. This change activates the receptor and initiates a series of intracellular events.
3: Signal Transduction: The activated receptor transmits the signal across the cell membrane. It can either directly activate intracellular signaling molecules or interact with other proteins to relay the signal.
4: Cellular Response: The signal transmitted by the mobile receptor triggers a cascade of intracellular events that ultimately leads to a specific cellular response. This response can include changes in gene expression, enzyme activity, ion channel opening, or cell signaling pathways.
5: Termination: To ensure proper regulation, the mobile receptor signal is terminated once the ligand dissociates from the receptor. This allows the receptor to return to its inactive state and be available for future signaling events.
Overall, the mechanism of mobile receptors involves ligand binding, receptor activation, signal transduction, cellular response, and termination of the signal. This intricate process enables cells to communicate and coordinate their functions, contributing to the overall homeostasis and functioning of the human body.
