How does the diaphragm remove air from the lungs?
When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.
When the diaphragm pushes upward, it increases the volume of the lungs, pushing air out.
When the diaphragm pulls downward, it increases the volume of the lungs, pushing air out.
When the diaphragm pulls downward, it decreases the volume of the lungs, pushing air out.
Answer: When, the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.
Explanation:
In exhalation, the diaphragm move upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of the respiratory system through the nose or mouth.
When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward. This makes the chest cavity bigger and pulls air through the nose or mouth into the lungs.

A. Clouded leopard
B. Rhinoseros
C. Whale
D. Frog
The skeleton is of Clouded leopard.
What are Extinct animal?Extinct species of animals are those that have stopped reproducing, perished, and ceased to exist. The extinction of a species is said to occur at the time of its last member's death.
Over the past 500 years, more than 900 species have become extinct. Due to habitat loss, a shortage of food supply, hunting, pollution, climate change, and excessive consumption, animals go extinct.
One of the most well-known extinct species is the dinosaur; it is thought that a meteor impact and/or numerous volcanic eruptions were responsible for its extinction.
Therefore, The skeleton is of Clouded leopard.

In a paragraph (at least 6 sentences)- Introduce Water Striders and tell how they are able to walk on water by explaining the relationship between hydrogen bonding, cohesion, surface tension, and buoyancy.
Answer:
Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water.
Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight. The legs of a water strider are long and slender, allowing the weight of the water strider body to be distributed over a large surface area. The legs are strong, but have flexibility that allows the water striders to keep their weight evenly distributed and flow with the water movement. Hydrofuge hairs line the body surface of the water strider.

Your friend shows you the image below and claims that it shows the process of mitosis. why is he or she wrong? (3 reasons)
Answer:
1. The cell splits itself twice
2. 4 resulting sperm cells are made
3. Only half of the DNA is kept per cell
Explanation:
Mitosis only has one diving phase that occurs only on body cells, which makes it have 2 daughter cells. This, on the other hand, has 4 daughter cells. If you notice, after the third set of bubbles, the genome(DNA) is split among 4 cells.
What is the difference between Organic and Inorganic material? Provide 3 examples of each and identify which one is likely to take the longest to break down in a landfill.

The primary difference between organic vs. inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon. Also, nearly all organic compounds contain carbon-hydrogen or C-H bonds.
Explanation:
Inorganic: 1. ammonia 2. all metals 3. calcium
Organic: 1. grass 2. wood 3. flowers

Answer:
Explanation:
fractured bone as the arm is swollen
Bruising can happen with almost any kind of tissue damage, including blood leaking from a broken bone. 1 The bigger the area of bruising, the more likely the damage is deep—possibly bone deep. Broken bones often swell. Swelling can be a sign that it's broken.
it will affect your skeletal system as you are unable to moth that part of your body and it also affect your muscular system as you can move your arm.
Broken bones are one of the most common orthopedic injuries. Fractures require treatment which may be as simple as rest, or as invasive as surgery. There are many factors that must be considered to determine the most appropriate treatment of a broken bone including: Some of the most frequently used fracture treatments are described here
that is most likely nerve damage as there is no bruising and it is numb so here nerve damage will be most logical.
muscular and nervous system as you are unable to feel or move your muscle.
muscle strain as it is when she overexercise her muscle which I sometimes experience at night.
it will most likely affect your muscular system
For immediate self-care of a sprain, try the R.I.C.E. approach — rest, ice, compression, elevation: Rest. Avoid activities that cause pain, swelling or discomfort. But don't avoid all physical activity.
Begin with blood flow in the left ventricle, recognizing how the vena cava, aorta, pulmonary artery and veins, right and left atriums, right and left ventricles, arteries, and veins all contribute to blood flow. Oxygenated and deoxygenated blood should also be described in your blood flow description.
Left ventricle, Aortic semilunar valve, Aorta, Arteries, Capillaries, Veins, Inferior vena cava, Right artrium, Tricupsid valve, Right ventricle, Pulmonary semilunar valve, Pulmonary artery, Lungs, Pulmonary veins ( Right & Left ).
Deoxygenated blood is received from the systemic circulation into the right atrium, it is pumped into the right ventricle whereas, The blood that is returned to the right atrium is deoxygenated while the left atrium receives newly oxygenated blood from the lungs through the pulmonary vein.

Explanation:
Plant pollen travels from the stamen to the stigma. Which step comes next in the pollination process?
Answer:
the next step would be germination.
Explanation:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.
Answer:
When a pollen grain moves from the anther (male part) of a flower to the stigma (female part), pollination happens. This is the first step in a process that produces seeds, fruits, and the next generation of plants. The stalk holds the anther and attaches it to the flower. The enlarged basal portion of the pistil where ovules are produced.
Explanation:
When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants.
